BMW Recalls 29,119 Plug-In Hybrids Over Starter Fire Risk on July 15

BMW is recalling 29,119 plug-in hybrid sedans in the United States over a fire hazard tied to the engine starter relay. Water can seep into the starter, causing corrosion and a short circuit that may trigger a fire even when the vehicle is parked and turned off. The recall affects 2016-2018 330e iPerformance, 2018-2020 530e and 530e xDrive, and 2017-2019 740Le xDrive models. BMW dealers will replace the starter assembly free of charge, with owner notification beginning August 28, 2026.

What is the defect

Water intrusion into the engine starter relay causes corrosion over time. The corroded relay can short circuit and overheat, creating a thermal event. This fire risk exists whether the car is running or parked with the ignition off. BMW tested 150 field-return starters earlier this year and documented two incident reports, one in November 2025 involving a 2019 5 Series and another in May 2026 involving a 2017 3 Series. The company estimates fewer than 0.1% of recalled vehicles will experience the failure.

How this recall connects to last year’s campaign

BMW issued a related recall in September 2025 covering roughly 196,000 conventionally powered 3, 4, X3, and X4 Series models, plus the Toyota Supra, for the same starter relay corrosion issue. Plug-in hybrid models were evaluated at that time but were not included. Continued monitoring of service data revealed the same failure mode appearing in plug-in hybrids that had been excluded from the first campaign.

Which models are affected and what owners should do

The recall spans four plug-in hybrid models: 2016-2018 330e iPerformance (7,852 units), 2018-2020 530e iPerformance (14,406 units), 2018-2020 530e xDrive (5,803 units), and 2017-2019 740Le xDrive (1,058 units). BMW dealers will replace the starter assembly at no cost. Owners are advised to park outside and away from structures until the repair is completed. Notification letters will begin arriving August 28, 2026. Owners who previously paid out-of-pocket for a starter replacement may request reimbursement.

No injuries reported yet

BMW says it has not received any reports of accidents or injuries tied to the starter relay defect. The company estimates the failure rate at fewer than 0.1% of the 29,119 recalled vehicles. Owners can verify whether their vehicle is included in the recall by entering the vehicle identification number on the BMW or NHTSA websites.

Final Thoughts

BMW owners of 2016-2020 plug-in hybrid sedans should check their recall status immediately and park outside until repairs begin in late August. The free replacement eliminates the fire risk, and prior out-of-pocket repairs may qualify for reimbursement.
