Verbatim excerpts from NHTSA complaints, by component

Engine

2 reports
“BMW issued a stop sale on 2017-2023 bmw F90 M5 chassis regarding the expansion tank failure. All vehicles should be affected by the recall. My current vehicle is experiencing the issues stated on the recall notice. Expansion tank is failing and causing coolant to seep into engine bay”
Owner complaint to NHTSAFiled Jun 17, 2024Unknown or other, EngineODI 11594879

Air bags

1 report
“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.”
