Plug-in electric vehicle fire

Frontal crash test of a Volvo C30 Drive Electric to assess the safety of the battery pack

Background

Numerous plug-in electric vehicle (EV) fire incidents have taken place since the introduction of mass-production plug-in electric vehicles. In some cases, an EV's battery (at least arguably) caused a fire. In other cases, an EV's battery did not cause a fire, but it added "fuel" to a fire. Technically: it is the "thermal propagation" properties of the battery pack which may, or may not, prevent it from getting involved in an automotive fire -- even if one or more of the cells in the battery pack has overheated dangerously, the upholstery has already caught on fire, or the car's wiring harness is severely damaged.

According to one research group:

The causes of fires in EVs can be mainly divided into the following categories: spontaneous combustion during driving, fire during charging, fire during vehicle parking, fire after collision (traffic accident and chassis collision), water immersion of battery packs, external fire ignition, human factors, aging and short-circuit of components, and charging equipment failure. For the first 3 categories, they can be classified as the state of the vehicle, rather than the apparent factors of the EV fires, because in these states, the status and integrity of the battery have not been changed, and the accident that occurred at these states can be considered to be caused by the battery pack's malfunction.

Based on the EV fire accidents collected from the internet in 2021... battery malfunction accounts for 50%, chassis collision accounts for 13%, water immersion, traffic accident, and external fire accounts for 7% separately. Charger or wire failure accounts for 5%, electrical failure accounts for 4%, customer retrofit accounts for 2%, and others account for 5%.

Regulatory Activity

In 2017, the United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) conducted a study to establish whether lithium-ion batteries in plug-electric vehicles pose an exceptional fire hazard. The research looked at whether the high-voltage batteries can cause fires when they are being charged, and when the vehicles are involved in an accident.

... Regarding the risk of electrochemical failure, [this] report concludes that the propensity and severity of fires and explosions from the accidental ignition of flammable electrolytic solvents used in Li-ion battery systems are anticipated to be somewhat comparable to or perhaps slightly less than those for gasoline or diesel vehicular fuels. The overall consequences for Li-ion batteries are expected to be less because of the much smaller amounts of flammable solvent released and burning in a catastrophic failure situation.

In 2021, the NHTSA established a Battery Safety Initiative for Electric Vehicles "to coordinate research and other activities to address safety risks relating to batteries in electric vehicles."

As at December 2024, the NHTSA planned to

"... [c]ontinue to advance battery safety through NHTSA’s participation in the development of Phase 2 of Global Technical Regulation No. 20 for Electric Vehicle Safety. NHTSA continues to advance electric vehicle and battery safety by chairing the development of the second phase of work currently underway at the UN. The activity is considering, among other things, safety issues related to battery thermal runaway, water immersion, and vibration resistance."

In September 2024, GlobalAutoReg's Informal Working Group on Electric Vehicle Safety convened in Tokyo for its 28th meeting. Thermal propagation was the primary topic on the agenda. In the view of this working group,

... thermal propagation continues to be the single most important issue in Phase 2 based on the field data... Chinese experts informed the meeting of the revisions to the national Thermal Propagation Test requirements and the physical robustness of the system; the European Commission’s expert reported on the progress of the Special Interest Group on Thermal Propagation (TP) in seeking an amendment of UNR. 100, and the US expert informed group of the rulemaking activities, specifically, that the US issued a Notice of Proposed Rulemaking (NPRM) in April 2024, which should be finalized by the end of 2024. The NPRM contains a proposal for a comprehensive documentation requirement for TP in all vehicle drive and park modes.

The expert from Korea gave an update on the investigation of the fire of an electric vehicle that resulted in injuries to 20 persons and damage to 900 vehicles in an underground garage in Seoul in August. As a result of this incident, Korea is considering tightening its testing requirements and certification procedures.

The group proceeded to discuss a way forward toward a successful resolution of Phase 2. The resulting table documented that there is a potential for a consensus on approaches to address thermal events and thermal propagation but all agreed that more work is needed.

The IWG plans its next in-person meeting for February 17-19 [2025] in Torrance, California, followed by a technical tour of Honda’s EV facility.

Safety guidelines for fire hazard

In the United States, General Motors ran, in several cities, a training program for firefighters and first responders to demonstrate the sequence of tasks required to safely disable the Chevrolet Volt's powertrain and its 12-volt electrical system, which controls its high-voltage components, and then proceed to extricate injured occupants. The Volt's high-voltage system is designed to shut down automatically in the event of an airbag deployment, and to detect a loss of communication from an airbag control module. GM also made available an Emergency Response Guide for the 2011 Volt for use by emergency responders. The guide also describes methods of disabling the high voltage system and identifies cut zone information. Nissan also published a guide for first responders that details procedures for handling a damaged 2011 Leaf at the scene of an accident, including a manual high-voltage system shutdown, rather than the automatic process built-in the car's safety systems.

Earlier NHTSA investigations

In August 2012, the National Highway Traffic Safety Administration (NHTSA) decided to begin a US$8.75 million study of whether lithium-ion batteries in plug-electric vehicles pose a potential fire hazard. The research looked at whether the high-voltage batteries can cause fires when they are being charged and when the vehicles are involved in an accident. The research from 2013 was initiated to evaluate the fire risk 400-volt lithium-ion batteries pose. General Motors assisted the NHTSA researchers, and the study was issued in October 2017. The report concluded, "...ignition of flammable electrolytic solvents used in Li-ion battery systems are anticipated to be somewhat comparable to or perhaps slightly less than those for gasoline or diesel vehicular fuels. The overall consequences for Li-ion batteries are expected to be less because of the much smaller amounts of flammable solvent released and burning in a catastrophic failure situation."(p. 11-2)

On October 24, 2019, the National Highway Traffic Safety Administration opened a Defect Petition for Tesla Model S and X vehicles manufactured between 2012 and 2019 related to battery fires not caused by collision or impact.

Responding to 2022 questions about the risk of fire and reignition related to contact of li-ion battery with salt water (seawater), as it appeared to happen in Florida following the passage of Hurricane Ian, Jack Danielson (executive director of NHTSA) wrote that what reported "is not an isolated event". He also quote tests and studies dated 2019 and 2021 on the subject.

Thermal Incidents in Electric Vehicles

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

A Future EV

About 6 a.m. on 17 November 2010, a fire broke out on the vehicle deck of the MS Pearl of Scandinavia on its way from Oslo to Copenhagen. The ferry's fire sprinkler system put out the fire before any of the crew or the 490 sleeping passengers were injured and the ship could dock in Copenhagen under its own power. It was determined that the cause of the fire was a short circuit in the plug of an extension cord used to charge a rebuilt Nissan Qashqai, converted into a battery electric vehicle by the Sakskøbing based company A Future EV. The company owner was returning from Norway where the vehicle had started the approval process for general sale there, and had used an extension cord to charge the vehicle from a general purpose power outlet on the ferry. The ferry operator DFDS Seaways consequently prohibited vehicle charging on board its ferries while the investors withdrew their support for the vehicle company forcing it into bankruptcy.

Zotye M300 EV

A Zotye M300 EV operating as a taxicab caught fire in Hangzhou, China, in April 2011. No one was injured as the driver and two passengers evacuated the electric car in time. Due to the incident, the city authorities decided to halt all electric taxis on safety concerns, 15 of which were M300 EVs out of a fleet of 30 electric taxis. The city's official investigation team found the cause of the fire was the car's defective battery pack due to lack of quality control during manufacturing. According to the investigation report, the battery pack problems include: leaking of battery cells; damage of the insulation between battery cells and the walls of the aluminum container in which the cells were stacked; short circuits occurred within certain containers and those involving supporting and connecting parts. One of the stronger short circuits ignited the car's back seats. The lead investigators said that "...in sealing and packing the battery cells, in loading and unloading the battery stacks, insufficient attention had been paid to several safety factors; monitoring procedures had been inefficient or neglected in the process of manufacturing, battery charging/switching, and vehicle driving, failing to detect anomalies." The report added that the battery cells on the car were made by Zhejiang Wanxiang Group.

Chevrolet Bolt

As of August 2021, Electrek had compiled a list of 18 battery-related Chevrolet Bolt fires, and one possible-battery related fire. The frequent fires resulted in a recall of about 110,000 Chevrolet Bolt and Bolt EUV EVs from the 2017 through 2022 model years.

Even after the recall, several fires occurred in vehicles that had received the new software and been checked by a dealer — including one in a vehicle owned by a Vermont state lawmaker. Another fire happened in New Jersey, the company told CNBC. GM says it's still investigating the fires, and is asking owners who haven't gotten the fix to take their Bolts in to a dealer regardless. At least nine fires have been documented, and the company has started buying back some Bolts. Moreover, the company recommended that Bolt owners park their cars outside and at least 50 feet away from other vehicles.

On September 13, 2021, a Chevrolet Bolt caught fire in a private garage in Cherokee County, Georgia, USA. The owner had either been unaware or simply ignored the recommendation to park outside.

Chevrolet Volt

As a result of a crash-tested Chevrolet Volt that caught fire in June 2011 three weeks after the testing, the National Highway Traffic Safety Administration (NHTSA) issued a statement saying that the agency does not believe the Volt or other electric vehicles are at a greater risk of fire than gasoline-powered vehicles. They added: "In fact, all vehicles –both electric and gasoline-powered – have some risk of fire in the event of a serious crash." The NHTSA announced in November 2011 that it was working with all automakers to develop post-crash procedures to keep occupants of electric vehicles and emergency personnel who respond to crash scenes safe.

In further testing of the Volt's batteries carried out by NHTSA in November 2011, two of the three tests resulted in thermal events, including fire. Therefore, the NHTSA opened a formal safety defect investigation on November 25, 2011, to examine the potential risks involved from intrusion damage to the battery in the Chevrolet Volt.

On January 5, 2012, General Motors announced that it would offer a customer satisfaction program to provide modifications to the Chevrolet Volt to reduce the chance that the battery pack could catch fire days or weeks after a severe accident. General Motors explained the modifications will enhance the vehicle structure that surround the battery and the battery coolant system to improve battery protection after a severe crash. The safety enhancements consist of strengthening an existing portion of the Volt's vehicle safety structure to further protect the battery pack in a severe side collision; add a sensor in the reservoir of the battery coolant system to monitor coolant levels; and add a tamper-resistant bracket to the top of the battery coolant reservoir to help prevent potential coolant overfill. On January 20, 2012, the NHTSA closed the Volt's safety defect investigation related to post-crash fire risk. The agency concluded that "no discernible defect trend exists" and also found that the modifications recently developed by General Motors are sufficient to reduce the potential for battery intrusion resulting from side impacts. The NHTSA also said that "based on the available data, NHTSA does not believe that Chevy Volts or other electric vehicles pose a greater risk of fire than gasoline-powered vehicles." The agency also announced it has developed interim guidance to increase awareness and identify appropriate safety measures regarding electric vehicles for the emergency response community, law enforcement officers, tow truck operators, storage facilities and consumers.

Fisker Karma

Fisker Karma plug-in hybrid.

In December 2011, Fisker Automotive recalled the first 239 Karmas delivered to the U.S. due to a risk of battery fire caused by coolant leak. Of the 239 cars, less than fifty had been delivered to customers, the rest were in dealerships. In the report filed by Fisker Automotive with the NHTSA, the carmaker said some hose clamps were not properly positioned, which could allow a coolant leak and an electrical short could possibly occur if coolant enters the battery compartment, causing a thermal event within the battery, including a possible fire. In May 2012 a Fisker Karma was involved in a home fire that also burnt two other cars in Fort Bend County, Texas. The chief fire investigator said the Karma was the origin of the fire that spread to the house, but the exact cause is still unknown. The plug-in hybrid electric car was not plugged in at the time the fire started and it was reported that the Karma's battery was intact. The carmaker release a public statement saying that "...there are conflicting reports and uncertainty surrounding this particular incident. The cause of the fire is not yet known and is being investigated." Fisker Automotive also stated that the battery pack "does not appear to have been a contributing factor in this incident." The NHTSA is conducting a field inquiry of the incident, and is working with insurance adjusters and Fisker to determine the fire's cause.

A second fire incident took place in August 2012 when a Karma caught fire while stopped at a parking lot in Woodside, California. According to Fisker engineers, the area of origin for the fire was determined to be outside the engine compartment, as the fire was located at the driver's side front corner of the car. The evidence suggested that the ignition source was not the lithium-ion battery pack, new technology components or unique exhaust routing. The investigation conducted by Fisker engineers and an independent fire expert concluded that the cause of the fire was a low temperature cooling fan located at the left front of the Karma, forward of the wheel. An internal fault caused the fan to fail, overheat and started a slow-burning fire. Fisker announced a voluntary recall on all Karmas sold to replace the faulty fan and install an additional fuse.

BYD e6

BYD e6 all-electric taxi in Shenzhen, China.

In May 2012, after a Nissan GT-R crashed into a BYD e6 taxi in Shenzhen, China, the electric car caught fire after hitting a tree killing all three occupants. The Chinese investigative team concluded that the cause of the fire was that "electric arcs caused by the short-circuiting of high voltage lines of the high voltage distribution box ignited combustible material in the vehicle including the interior materials and part of the power batteries." The team also noted that the battery pack did not explode; 75% of the single cell batteries did not catch fire; and no flaws in the safety design of the vehicle were identified.

On December 29, 2020, a BYD e6 taxi caught fire at an intersection in Luohu District, Shenzhen, China.

BYD Han EV

In July 2021, Dongchedi (Chinese: 懂车帝), a ByteDance's automotive media in China, performed a crash test of BYD Han EV versus Arcfox Alpha-S. Having been parked for 48 hours after the test, only the Han EV caught fire and burned to the ground.

On June 15, 2022, a BYD Han EV caught fire on a road in Xaysetha district, Vientiane, Laos.

BYD Tang

On November 15, 2021, a BYD Tang EV caught fire in a workshop in Kristiansand, Norway.

On January 26, 2022, a BYD Tang DM-i (plug-in hybrid) caught fire on a flatbed tow truck, on a road in mainland China. By the such kind of transporting, it seems to be a malfunctioning car.

BYD Qin

On May 28, 2020, a BYD Qin Pro EV caught fire at a charging station in Shenzhen, China.

On October 28, 2020, a BYD Qin Pro EV caught fire after charging completed in Yantai, Shandong province, China.

On November 22, 2021, a BYD Qin Pro EV caught fire in an underground parking lot in Beijing, China.

On February 13, 2022, a BYD Qin Plus DM-i (plug-in hybrid) caught fire on a road in Zhongshan city, Guangdong province, China.

BYD Atto 3

On September 3, 2023, a BYD Atto 3 suffered smoke and heat damage to the engine compartment when charging at a charging station in Mueang Udon Thani district, Udon Thani, Thailand. Investigation showed that the damage was caused by a wire attached to the 12 V lead–acid battery, not the vehicle's main EV battery pack.

Dodge Ram 1500 Plug-in Hybrid

Dodge Ram 1500 Plug-in Hybrid demonstrator

In September 2012, Chrysler temporarily suspended a demonstration program that it was conducting with 109 Dodge Ram 1500 Plug-in Hybrids and 23 Chrysler Town & Country plug-in hybrids. All units deployed in the program were recalled due to damage sustained by three separate pickup trucks when their 12.9 kWh battery packs overheated. The carmaker plans to upgrade the battery packs with cells that use a different lithium-ion chemistry before the vehicles go back on service. Chrysler explained that no one was injured from any of the incidents, and the vehicles were not occupied at the time, nor any of the minivans were involved in any incident, but they were withdrawn as a precaution. The carmaker reported that the demonstration fleet had collectively accumulated 1.3 million miles (2.1 million km) before the vehicles were recalled. The demonstration is a program jointly funded by Chrysler and the U.S. Department of Energy that includes the first-ever factory-produced vehicles capable of reverse power flow. The experimental system would allow fleet operators to use their plug-in hybrids to supply electricity for a building during a power outage, reduce power usage when electric rates are high or even sell electricity back to their utility company.

Fires related to Hurricane Sandy flood

In separate incidents during the storm and flooding caused by Hurricane Sandy on the night of October 29, 2012, one Toyota Prius Plug-in Hybrid and 16 Fisker Karmas caught fire while being parked at Port Newark-Elizabeth Marine Terminal. The vehicles were partially submerged by flash floods caused by the hurricane. In the case of the Toyota's incident, a Prius PHV burned and two other Priuses, a conventional hybrid and a plug-in, just smoldered. A Toyota spokeswoman said the fire "likely started because saltwater got into the electrical system." She also clarified that the incident affected only three cars out of the 4,000 Toyotas that were at the terminal during the storm, including more than 2,128 plug-in or hybrid models. Fisker Automotive spokesman said that the Karmas were not charging at the time of the fire and there were no injuries. After an investigation by Fisker engineers, witnessed by NHTSA representatives, the company said that the origin of the fire was "residual salt damage inside a Vehicle Control Unit submerged in seawater for several hours. Corrosion from the salt caused a short circuit in the unit, which led to a fire when the Karma's 12-Volt battery fed power into the circuit." The company explained that Sandy's heavy winds spread that fire to other Karmas parked nearby, and also ruled out the vehicles' lithium-ion battery packs as a cause of, or a contributing factor to, the fire.

Mitsubishi i-MiEV and Outlander P-HEV

Mitsubishi Outlander P-HEV

In March 2013, Mitsubishi Motors reported two separate incidents with lithium-ion batteries used in its plug-in electric cars, one with a Mitsubishi i-MiEV electric car and the other with an Outlander P-HEV plug-in hybrid. The battery packs are produced by GS Yuasa, the same company that supplies the batteries for the Boeing 787 Dreamliner, whose entire fleet was grounded in January 2013 for battery problems. The lithium-ion battery of an i-MiEV caught fire at the Mizushima battery pack assembly plant on March 18 while connected to a charge-discharge test equipment. Three days later, the battery pack of an Outlander P-HEV at a dealership in Yokohama overheated and melted some of the battery cells, after the vehicle had been fully charged and stood for one day. Nobody was injured in either incident.

Mitsubishi did not issue a recall but halted production and sales of the two models until it determines the causes of the battery problems. The carmaker advised owners of the Outlander plug-in hybrid to drive only on gasoline mode for the time being. In the case of the i-MiEV, the problem is related with a change in GS Yuasa manufacturing process, and Mitsubishi called fleet-vehicle operators with i-MiEVs whose batteries were made under the same process as those that overheated and is working on a possible fix. In August 2013, and after changing a production process to avoid damaging any batteries, Mitsubishi restarted production of the Outlander plug-in hybrid.

In May 2019, an Outlander caught fire after immersion in salt water. The vehicle was being used to haul a boat trailer out of the water at a Port Moody boat ramp when the driver lost control. After a tow truck recovered the Outlander, what appears to be the battery pack caught fire.

Tesla Model S, 3, X, and Y

Tesla Model S

Although the frequency of fires in a Tesla is about an order of magnitude below fires in gasoline cars, there are 44 known cases of deaths involving incidents of Tesla car fires. The following list of Tesla car fires is not comprehensive:

A Tesla Model S caught fire after the vehicle hit debris on a highway in Kent, Washington, on October 1, 2013. According to the driver, he hit something while traveling in the HOV lane of Washington State Route 167, and exited because the car reported a problem and told him to stop. Flames began coming out of the front of the car at the end of the off-ramp, so the driver left the car. The fire was caught on video by a witness and posted on several websites. According to the Kent Fire Department incident report, initial attempts to extinguish the fire with water were unsuccessful, as the fire reignited underneath the vehicle after appearing to be extinguished. Then, the firefighters cut a hole to apply water directly to the burning battery. According to Tesla, the car owner was alerted by onboard systems to stop the car and exit the vehicle, which he did without injury.

The carmaker confirmed the fire began in the battery pack and it was caused by an impact to one of the battery pack modules by a large piece of metal from a semi-trailer and that the design of the battery pack had isolated the fire to the front section's internal firewalls.

The company also said that conventional gasoline-powered cars were much more vulnerable to such a situation, because they have less underbody protection. It also noted that the battery pack holds only about 10% of the energy contained in a gasoline tank and is spread across 16 firewalled modules, meaning that the combustion potential is only about 1% as much. Elon Musk posted on his blog that, based on U.S. automobile miles-per-fire statistics from the National Fire Protection Association, a driver is "5 times more likely to experience a fire in a conventional gasoline car than a Tesla." After news of the accident, Tesla's listed shares fell 6.24% in NASDAQ trading the next day, and an additional 4% the following day, closing at US$173.31. The stock recovered by 4.4% at the closing of the week.

Tesla's CEO, Elon Musk, issued an official statement on October 4, 2013. The statement said that a curved piece of metal from a semi-trailer that had fallen on the roadway appeared to have impaled the one-quarter-inch (6.4 mm) plate on the base of the vehicle. According to the statement, in order for the object to have made a 3-inch (7.6 cm) diameter hole in the plate, the object must have had enough leverage to produce approximately 25 short tons-force (220 kN). After the driver exited the car, the statement continued, the frontmost of the car's 16 battery modules caught fire due to the initial damage, but the battery pack's internal firewalls kept the fire from spreading and vents directed the flames away from the car down towards the pavement. The statement also noted that the fire never entered the passenger compartment. According to Tesla, the firefighters observed standard procedure, and gained access to the source of the fire by puncturing holes in the top of the battery's protective metal plate and applying water. However, the company noted that although the water and dry-chemical fire extinguisher quickly put out the fire, the firefighters should not have punctured the firewall since the new holes allowed flames to enter the front trunk of the vehicle. Musk closed the official statement explaining that the result of this accident could have been "far worse" had a conventional gasoline-powered car encountered the same object on the highway, because most gasoline cars do not have an armored underbody, leaving the fuel lines and tank vulnerable. He also noted that Tesla's battery pack only contains about 10% as much energy as a standard tank of gasoline and it is divided into 16 sections means that the combustion potential is about 1% of a comparable gasoline-powered car. Based on U.S. statistics from the National Fire Protection Association, Musk's statement claimed that a fire was five times more likely in a gasoline car than in a Tesla car.

The U.S. National Highway Traffic Safety Administration (NHTSA) was not able to send investigators to the scene of the incident due to the U.S federal government shutdown. After the agency reopened, the NHTSA began gathering data of the incident. On 24 October 2013, the agency announced it will not open a formal investigation into the Model S fire incident, saying that they had not found evidence that the fire was caused by a vehicle defect or noncompliance.

A second reported fire occurred on October 18, 2013, in Merida, Mexico. In this case, the vehicle was being driven at high speed through a roundabout and crashed through a wall and into a tree. The NHTSA did not investigate this incident because it occurred outside the U.S. There have since been several additional fires, caused by catastrophic high speed collisions, which are omitted from this list because they do not illustrate problems unique to electric drive trains. (Incidents which illustrate issues with Tesla's Autopilot features, including some that lead to car fires, are listed here)

A Tesla Model S being driven on Interstate 24 near Murfreesboro, Tennessee caught fire on November 6, 2013, after it struck a tow hitch on the roadway, causing damage beneath the vehicle. Tesla Motors stated that it would conduct its own investigation, and as a result of these incidents, the company announced its decision to extend its current vehicle warranty to cover fire damage and to apply a software update on Model S cars to increase the ground clearance of the Model S when driving at highway speed.

On November 19, 2013, based on the two fire incidents occurring on U.S. public highways, the NHTSA opened a preliminary evaluation to determine if undercarriage strikes presented an undue fire risk on the 2013 Tesla Model S. An estimated population of 13,108 Model S cars were part of this initial investigation.

On November 15, 2013, a fire broke out in an Irvine, California garage where a Tesla Model S was plugged in and charging. The fire appears to have originated at the wall connection where the Tesla charging equipment was plugged in. Shortly afterwards, Tesla updated the Model S firmware to reduce charging current when power fluctuations were detected and replaced wall adapters with a new unit containing a thermal fuse.

On November 18, 2013, Tesla released a software update to the air suspension system to increase the ground clearance at highway speeds and requested that the NHTSA conduct an investigation into the fire incidents. Another fire incident took place in Toronto, Canada, in early February 2014. The Model S was parked in a garage, and it was not plugged in or charging when the fire started. As of February 14, 2014, the origin of the fire was still unknown. Tesla's response was that "[i]n this particular case, we don't yet know the precise cause, but have definitively determined that it did not originate in the battery, the charging system, the adapter or the electrical receptacle, as these components were untouched by the fire."

On March 28, 2014, the NHTSA announced that it had closed the investigation into whether the Model S design was making the electric car prone to catch fire, after the automaker said it would provide more protection to its lithium-ion batteries. According to the NHTSA, the titanium underbody shield and aluminum deflector plates, along with increased ground clearance, reduce the severity, frequency, and fire risk of underbody strikes. All Model S cars manufactured after March 6 have the 0.25-inch (6.4 mm) aluminum shield over the battery pack replaced with a new three-layer shield designed to protect the battery and charging circuitry from being punctured even in very high speed impacts. The new shielding features a hollow aluminum tube to deflect impacting objects, a titanium shield to protect sensitive components from puncture damage, and an aluminum extrusion to absorb impact energy. The new shields, which decrease vehicle range by 0.1%, will be installed free-of-charge in existing Model S vehicles by request or during the next scheduled maintenance. According to the NHTSA, the titanium underbody shield and aluminum deflector plates, along with increased ground clearance, "should reduce both the frequency of underbody strikes and the resultant fire risk."

A fire occurred in a Tesla Model S charging at a Tesla Supercharger in Norway on January 1, 2016. The fire was slow, and the owner had time to unplug the car and retrieve possessions. An investigation by the Norwegian Accident Investigation Board (AIBN) indicated that the fire originated in the car, but was otherwise inconclusive. In March 2016, Tesla stated that their own investigation into the incident concluded that the fire was caused by a short circuit in the vehicle's distribution box, but that the amount of damage prevented them from determining the exact cause. Tesla stated that the Supercharger detected the short circuit and deactivated, and a future Model S software update would stop the vehicle from charging if a short circuit is detected.

On August 15, 2016, a new Tesla Model S 90D spontaneously caught fire during a promotional test drive in Biarritz, France. Following a sudden, loud noise the dashboard presented the driver with a warning of a "charging" problem. Following advice from a passenger Tesla employee, the driver pulled over and all three occupants safely exited the vehicle. Moments later the vehicle started burning and although firefighters quickly arrived, the fire completely destroyed the vehicle within 5 minutes. Tesla subsequently determined that the vehicle in question had a "bolted electrical connection" which would normally have been tightened by a robot, but which in this case had been "improperly tightened" by a human, causing the fire.

On August 25, 2017, the driver of a Model X lost control of the vehicle, which went over an embankment and struck a garage in Lake Forest, California, starting a fire that damaged the car and structure. The NTSB stated the resulting battery fire was under investigation.

On May 8, 2018, an 18-year-old lost control of his Tesla Model S while driving 116 mph in a 30 mph zone and hit the curb, a wall, the curb and a light pole causing the battery pack to ignite; the car was reportedly modified to be limited to a top speed of 85 mph. The driver and passenger died in the crash and subsequent fire. The battery pack reignited twice, requiring fire fighters to extinguish the burning battery pack three times. In reaction to this accident, Tesla sent an over-the-air firmware update that allows limiting the top speed to between 50 and 90 mph dedicated to the deceased driver.

On May 10, 2018, a Tesla S caught fire after hitting the guard-rail on the Swiss A2 highway on Monte Ceneri, between Lugano and Bellinzona, killing the 48-year-old German driver.

On June 16, 2018, pedestrians on a Los Angeles street alerted a driver of a Tesla Model S that smoke was emanating from his vehicle. The driver pulled over and safely exited the vehicle and flames started shooting out from under it. Firefighters quickly extinguished the fire, which left the cabin unaffected. The National Transportation Safety Board subsequently stated that they would monitor Tesla's investigation of the fire to learn more about fires in battery-powered vehicles, while the NHTSA stated that it collects information regarding the incident and would take action as warranted.

On February 8, 2019, A Tesla Model S caught on fire in a private garage in Pittsburgh. Two months later, on April 8, it caught on fire again, while it was under investigation. On February 24, 2019, a Tesla Model S that crashed into a tree burst into flames and burned its driver beyond recognition Sunday evening along Flamingo Road in Davie, Florida, then repeatedly caught fire after being brought to the tow yard used by police.
