The National Highway Traffic Safety Administration (NHTSA) has announced a sweeping recall of nearly 196,355 BMW vehicles in the United States due to a serious fire hazard linked to the cars’ electrical system. The agency issued the warning on Friday, urging affected vehicle owners to park their cars outside and away from buildings or other vehicles until repairs are completed.
The recall was prompted by concerns that a key electrical component—the engine starter relay—may corrode over time, leading to overheating, short-circuits, and in worst cases, a potential fire. According to NHTSA, the defect could cause fires whether the vehicle is being driven or is parked.
Models Affected by the Recall
NHTSA and BMW confirmed that the recall spans a wide range of popular BMW models produced between 2019 and 2022. The affected vehicles include:
- BMW Z4 (model years 2019–2022)
- BMW 330i (2019–2021)
- BMW X3 (2020–2022)
- BMW X4 (2020–2022)
- BMW 530i (2020–2022)
- BMW 430i – both standard coupe and convertible versions (2021–2022)
- BMW 230i (2022)
- Toyota Supra (2020–2022) – about 1,469 units built by BMW
The inclusion of the Toyota Supra may surprise some owners, but this model is manufactured in partnership with BMW and shares the same four-cylinder B48 turbocharged engine and electrical relay system. This means the Supra is vulnerable to the same fire risk as the BMW lineup.
What Owners Should Do Immediately
NHTSA stressed that safety should be the top priority for affected vehicle owners. Until repairs are available, BMW and Toyota owners should:
- Park their vehicles outdoors, away from garages, homes, or other cars.
- Avoid leaving the cars unattended near flammable materials.
- Check their vehicle recall status beginning November 14, 2025, by visiting NHTSA’s recall website. Owners can enter their 17-digit VIN or license plate number to confirm whether their car is included in the recall.
- Wait for official BMW or Toyota notifications, which will begin mailing out on November 14. A second round of letters will be sent once repair parts are available.
- Schedule free repairs at authorized dealerships once BMW confirms parts distribution. The automaker has promised to replace the faulty starter relay at no cost to vehicle owners.
For questions, owners can also call NHTSA’s Vehicle Safety Hotline at 888-327-4236 or contact BMW customer service directly.
Why the Starter Relay Is a Problem
The starter relay is a critical electrical component that controls current flow from the battery to the starter motor when the car is turned on. According to NHTSA’s technical investigation, the relay in these BMW and Toyota models may be vulnerable to moisture intrusion and corrosion.
When corrosion builds up inside the relay, it can:
- Increase electrical resistance.
- Cause the relay to overheat.
- Lead to a short circuit.
- Spark and ignite nearby components, creating a fire hazard.
Importantly, this risk is present even when the car is turned off and parked, since the relay is still connected to the battery circuit. That is why NHTSA explicitly warned owners to keep their cars parked outdoors.
BMW’s Response and Recall Timeline
BMW told regulators that the recall will be handled in phases, due to parts availability. The company acknowledged the fire risk but emphasized that it is not aware of any confirmed injuries or fatalities caused by the defect so far.
- Interim notification letters: Sent beginning November 14, 2025.
- Second notification letters: To be mailed once replacement parts are ready.
- Free repair program: Owners will be able to bring affected cars to dealerships for a free starter relay replacement.
BMW has not provided an exact timeline for when all parts will be available, but NHTSA indicated the automaker is working with suppliers to accelerate production.
Toyota Supra Owners Also Impacted
Because the 2020–2022 Toyota Supra is built on a BMW platform at BMW’s Graz, Austria factory, it shares identical electrical systems with the Z4. As a result, nearly 1,500 Supras sold in the U.S. are also included in the recall.
Toyota has confirmed that it will notify Supra owners directly and coordinate with BMW to supply the necessary replacement parts. Supra owners are advised to follow the same safety precautions and check recall databases using their VINs.
History of BMW Recalls Over Fire Risks
This recall is not BMW’s first fire-related safety issue. In fact, BMW has faced similar problems in recent years:
- 2017: BMW recalled more than 1 million cars and SUVs worldwide over risk of fires caused by wiring and ventilation system defects.
- 2019: The company expanded that recall to another 185,000 vehicles, again citing fire risks from faulty electrical components.
- 2024: BMW recalled over 105,000 vehicles due to overheating starter motors, a related issue in the electrical system.
- August 2024: The company also recalled 720,796 vehicles because water could seep into an improperly sealed water pump connector, increasing fire risks.
These repeated recalls highlight the increasing complexity of modern vehicles and the challenges manufacturers face with electrical and electronic component reliability.
What This Means for Car Owners
For affected BMW and Toyota owners, the key takeaway is simple:
- Don’t ignore the recall. Even if your car seems to run fine, the risk of fire is real and could happen while parked.
- Check your vehicle status as soon as the VIN search becomes available.
- Stay alert for official letters and instructions from BMW or Toyota.
- Take advantage of free repairs once dealerships are ready to handle the replacements.
Until then, the safest option is to follow NHTSA’s advice—keep your car parked outdoors, away from buildings or other vehicles, and avoid unnecessary risks.
