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

ENGINE

1 complaint

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.

AIR BAGS,SEAT BELTS

1 complaint

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.

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. I CONTACTED MY DEALERSHIP TODAY, ONLY TO BE INFORMED, THIS WAS AS A RESULT OF COMPUTER GLITCH CONTROLLING THE FUEL PUMP CAUSING IT TO SHUT OFF WITHOUT WARNING. I WAS TOLD THERE HAS BEEN A SOFTWARE PATCH TO REMEDY THIS PROBLEM. IF IT IS TRUE, I BELIEVE THE CORRECTION SHOULD HAVE BEEN DONE BEFORE THE CAR WAS PICKED UP OR PROMPTLY NOTIFIED TO RETURN THE CAR FOR FIXING. I COULD HAVE BEEN KILLED ON THE HIGHWAY LAST NIGHT IF NOT FOR MY PROMPT SITUATION AWARENESS AND EXPERIENCE IN HANDLING THIS POWERFUL CAR WHICH IS MY FOURTH M5 SINCE 2006. OWNERS NEED TO BE NOTIFIED IMMEDIATELY FOR FIXES LIKE THIS THAT CAN LEAD TO FATAL INCIDENTS. I DON'T KNOW IF ANYTHING SIMILAR HAS BEEN REPORTED ABOUT THIS MODEL
