Example complaints

Engine: “The coolant tank on my 2018 M5 failed causing a coolant leak. This is a highly documented problem on the forums and mine needed replacement at 22k miles. The bigger issue is the location of the tank because the coolant leaks on the ignition coils and fuel injectors causing failures later. My coils and spark plugs needed replacement along with the tank. This is unacceptable and BMW needs to address this issue.”

NHTSA complaint #11585423, filed 2024-04

Air bags: “This is for the front passenger seat only.The idrive system will give an error for the passenger restraint system and will mention there is a seat belt issue and turn off the airbag. This is intermittent and will happen with or without a passenger. I contacted BMW about it but because it is not presently acting out, they won't do anything about it unless I want to just start paying for new parts and do exploratory surgery on it trying to resolve this. Unacceptable as this has been happening for a couple of years and is a danger because of it happens during an accident it could prove fatal.”

NHTSA complaint #11577017, filed 2024-03

Brakes: “I had gotten into a head on collision in January. My insurance had refused to cover me because I had only been insured for a month. Now I’m trying to get it fix out of pocket. I’m finding out about more repairs needed ASAP. My engine might be gone.”

NHTSA complaint #11729136, filed 2026-04

Fuel system: “I almost had a terrible accident in my 2 week old 2018 M5 on the 1-95 highway on the night of may 25, 2018 at about 9:45pm. Without warning, at about 65mph, the car jerked for about 3seconds , kicked out of drive into neutral and started decelerating. I was in the middle lane surrounded by speeding vehicles. I managed to guide it to the shoulder and turned off the ignition for 2minutes, after which I re-started the car and was able to engage drive. …”
