BMW and Toyota have announced a voluntary safety recall affecting certain 2019–2022 BMW models and 2020–2022 Toyota Supra vehicles due to a potential fire risk involving the engine starter relay. The issue arises when water makes contact with the relay, which over time may corrode and compromise the electrical connection. While corrosion can make it difficult or impossible to start the engine, in more severe cases it can cause the relay to short-circuit and overheat. This overheating poses a significant fire hazard, as a thermal event could occur not only while the vehicle is being driven but also when it is parked with the ignition off.
BMW launched an engineering investigation in July 2024 after reports of thermal events in certain vehicles. Over the following year, engineers analyzed field cases, conducted parts tear-downs, and tested water ingress scenarios in an attempt to replicate the failure. Although no single cause was definitively confirmed, BMW identified production periods that may be at risk. On September 16, 2025, the automaker initiated a recall. Toyota conducted its own review of records and confirmed no U.S. reports of Supra incidents to date, but vehicles remain included in the recall as a precaution.
Owners of affected vehicles are strongly advised to park outdoors and away from buildings until repairs are complete. Dealers will address the issue by replacing the engine starter at no cost to customers. Interim recall notices will begin mailing on November 14, 2025, with a follow-up notice sent once replacement parts are available. The recall is listed under NHTSA Campaign Number 25V-636.
Affected Vehicles Include:
- 2019–2021 BMW 330i
- 2021–2022 BMW 430i
- 2021–2022 BMW 430i Convertible
- 2020–2022 BMW 530i
- 2020–2022 BMW X3
- 2020–2022 BMW X4
- 2019–2022 BMW Z4
If you own one of these vehicles, stay alert for recall notifications, and in the meantime, take the precaution of parking your vehicle outside until the remedy is performed.
