Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Car randomly shows “Passenger restraint system malfunction”. I have read multiple complaints from other BMW owners about this issue that is not covered under BMW warranty.

NHTSA ID 11595827 · filed Jun 21, 2024

My car is producing a warning light for "Passenger restraint system malfunction". This is a safety hazard and it is not covered by warranty. I believe this should be investigated and a recall should be mandated as many people have this issue. The cost to fix is over $2,500 and BMW should bear the cost of this safety issue.

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.

NHTSA ID 11682017 · filed Aug 20, 2025

I was driving home after picking my son up from school and out of no where the vehicle temperature was in the red and a message popped up stating that vehicle coolant needed to be replenished but that continued driving of the vehicle was ok. It was not ok at all! The car started smoking and we were left stranded on the side of the road. I’ve read numerous blogs showing that the same thing has happened to other people and that there have even been recalls on other bmw’s in regards to the engine coolant system.

Passenger Restraint system malfunction warning keeps appearing. This car has never been in an accident or had any moisture, spills etc. that would cause that to happen. I'm reporting it as an issue due to the many complaints by BMW customers with the same issue. BMW charges $2500 to fix for this very common problem.

Passenger Restraint System Malfunction. This is what randomly and constantly pops up. The fasten seat alert goes off the whole time I’m riding, although no one is in the passenger seat. I took it to the BMW service center twice and each time they keep my vehicles for hours, just to say they couldn’t duplicate the issue.
