BMW is facing one of its largest recalls in recent years, pulling back more than 330,000 vehicles worldwide after regulators identified a serious fire hazard tied to defective starter motors. The U.S. National Highway Traffic Safety Administration (NHTSA) confirmed the campaign on Friday, urging owners not to park affected models inside garages or near buildings until repairs are made.
Corrosion at the Core of the Problem
Investigations revealed that the defect stems from the starter motor relay, which can corrode if exposed to moisture. This corrosion may prevent the vehicle from starting, but in more severe cases, it can lead to overheating and short circuits. Both BMW and NHTSA have warned that such conditions could cause vehicles to catch fire even hours after being shut off.
BMW acknowledged that water penetration in certain starter motor assemblies manufactured between late 2015 and 2021 is responsible. The company traced the issue through its internal product testing and multiple field complaints that pointed to recurring failures.
U.S. and German Markets Hit Hardest
The recall spans a broad lineup, with 196,000 vehicles impacted in the U.S. and at least 136,500 more in Germany. Globally, nearly all BMW models produced between September 28, 2015, and September 7, 2021, are affected, except for some compact models with transverse engines and M-performance variants that used different components.

Safety Warnings for Owners
Both BMW and regulators are stressing caution. Owners have been advised not to park indoors or near structures until the remedy is applied. The warning echoes safety measures seen in past industry recalls linked to fire risks, underlining the seriousness of the defect.
NHTSA issued its own statement reinforcing the guidance: “Owners are advised to park their vehicles outside and away from structures until the remedy is complete.”
Repair Program to Begin in November
BMW confirmed that repairs will start rolling out in mid-November. Owners in the U.S. will receive official notices beginning November 14, 2025. They can verify whether their vehicles are included by entering the VIN at NHTSA.gov/recalls.
The remedy will involve a complete replacement of the starter motor at no cost to customers. In some cases, vehicles may also receive a new battery to ensure long-term safety. Repairs will be performed exclusively at authorized BMW dealerships worldwide.

What This Means for BMW
The recall adds to a string of recent safety campaigns across the auto industry, highlighting the challenges of managing complex electrical systems in modern vehicles. For BMW, it raises questions about supplier oversight and long-term reliability but also demonstrates the brand’s willingness to act preemptively once risks are identified.
As the company works to replace parts in hundreds of thousands of vehicles, owners are left balancing frustration with relief—frustration over the inconvenience, but relief that the danger was flagged before it could cost lives.
