BMW is recalling nearly 30,000 plug-in hybrid sedans across the United States due to a faulty engine starter relay that presents a serious fire risk
The affected lineup includes specific 3 Series, 5 Series and 7 Series models produced between 2016 and 2020 that share a starter design susceptible to water intrusion
Owners are strongly advised to park their vehicles outdoors and away from structures until dealership technicians can install an upgraded component
BMW is issuing a safety recall for 29,119 plug-in hybrid sedans in the US over a critical fire hazard. The National Highway Traffic Safety Administration identified a serious flaw in the engine starter relay of several prominent luxury models. Affected vehicles include the 2016 to 2018 330e iPerformance, the 2017 to 2019 740Le xDrive iPerformance and the 2018 to 2020 530e iPerformance variants. Owners of these specific cars are being instructed to park outside and far away from buildings until the manufacturer can resolve the dangerous mechanical defect.
The root of the issue stems from a design vulnerability where water can seep into the starter housing and trigger rapid corrosion. This degradation frequently leads to engine starting difficulties and can ultimately cause an electrical short circuit. According to the automaker, extreme cases present a distinct risk of an unexpected thermal event. The compromised relay can overheat and catch fire whether the car is actively driving or sitting parked with the ignition turned completely off.
This latest safety campaign expands upon a widespread 2025 recall that impacted nearly 200,000 conventionally powered BMW models alongside the Toyota Supra. Following that initial push to secure combustion engines, investigators analyzed approximately 150 starters pulled from hybrid models in the field. While no crash or injury reports have been linked to the hybrid starter failures, the findings prompted the brand to take immediate preventative action to mitigate any lingering short-circuit threats across its electrified lineup.
BMW dealership technicians will perform the necessary repairs completely free of charge by replacing the faulty starter with a newly engineered component. Official notification letters are scheduled to be mailed to owners beginning August 28, 2026. Until the upgraded parts are securely installed, the strict directive remains clear for drivers to keep their luxury hybrids out of residential garages.
