The oil filter housing has a plastic coolant passage that cracked. That lead to a complete loss of coolant, leaving my teenage daughter stranded. The problem seems pretty wide spread on these cars and happens right around the end of the warranty period. It could have been a more than $2500 repair. I ended up fixing it myself for a little less.

It was not ok at all! The car started smoking and we were left stranded on the side of the road. Iâve read numerous blogs showing that the same thing has happened to other people and that there have even been recalls on other bmwâs in regards to the engine coolant system.

I parked my car and there were not any lights on the showing. When I returned to my car about an hour later 2 lights were shown (1) 4 wheel drive and (2) Passenger restraint system. I am concerned about the passenger restraint system because until I can get this repaired, no one can use the passenger seat because of this safety issue.
