The BMW Fire Recall Just Got Company
BMW initially recalled approximately 196,000 vehicles in late September after discovering that starter motor relays could corrode and potentially catch fire. The affected models included 2019 through 2021 BMW 330i sedans, 2019 through 2022 Z4 roadsters, 2020 through 2022 models of the 530i, X3, and X4, plus 2021 through 2022 versions of the 430i and its convertible variant, and 2022 BMW 230i models. Even some Toyota Supras made the list since they share BMW components.
The problem is that moisture can get into the starter motor units. When water penetrates these components, the starter relay can corrode, overheat, and short circuit. The truly concerning part is that these fires can ignite hours after you've parked and walked away. BMW advised owners not to park inside garages or near buildings until repairs are completed.

BMW’s Starter Motor Woes Are Far From Over
Just when BMW owners thought they could relax, the company announced another recall affecting over 145,000 additional vehicles for the exact same starter motor fire risk. This second recall targets 2020 model year 340i sedans plus additional X7 and X5 SUVs.
The combined recalls now affect well over 340,000 vehicles in the United States alone. BMW has identified the issue across nearly all model lines produced between September 2015 and September 2021, with the exception of some compact models and M performance variants that used different suppliers.

What BMW Owners Can Do To Safeguard Their Cars
First, check if your vehicle is included in the recall. BMW will replace the faulty starter motor, with some models also receiving a new battery. Repairs will be handled through authorized dealerships. Unfortunately, BMW doesn’t have replacement parts ready just yet, so waiting is the only option.
Until then, follow BMW's guidance and park outside, away from other vehicles and structures. The good news is the fix is free. The bad news is your BMW might spontaneously combust before you can schedule the appointment.
