I was leaving the parking lot at XXX downtown [XXX] around 12:30 a.m. with my passenger when the vehicle out of nowhere started throwing multiple errors and warnings. I lost the ability to break and I lost steering. I completely lost the ability to slow down the car using the brake pedals. Luckily I was not moving fast and I was able to come to a rolling stop. Have I been in heavier traffic or have been traveling faster this most certainly have resulted in an accident, potentially causing injury or worse for me and or my passenger. It was a very scary situation and my safety was at risk. BMW assistance was not able to provide Tow Service due to the time of the hour and availability so I called Boca Raton police department and they provided with a towing service to the dealership at BMW Coconut Creek where the car has been since. The service at the above dealership is currently inspecting the car and I'm looking to find out the result of their investigation. I am aware of the current recall of the brake booster system however I want to emphasize that "safe mode" degraded breaking was not available does not match what happened in my situation. In my case I had no breaking power whatsoever and I could not stop the car even from a very low speed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2026 BMW I4 Gran Coupe Bev verdict →
