What 2018 BMW M5 owners say
Engine & cooling
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.
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
