Example complaints

Electrical system: “I’ve been having issues with the front end since I purchased the vehicle. The dealership had not diagnosed this issue yet in 3 years. It had caused my vehicle to be in the shop continuously, my front driver side tire is worn out. I had to replace all brakes and rotors after 2 years, numerous sensor issues, radiator loses fluid as well as software issues.”

NHTSA complaint #11630662, filed 2024-12

Brakes: “On July 27, 2024, the parking brake on this car would not disengage, thus, I was unable to drive my car. We had to turn off the car for 15 minutes and then step on the gas and brake at the same time at which point the park brake disengaged. I believe this is a safety/manufacturer issue that needs to be addressed and should be under a broader warranty protection (like 100,000 miles or more).”

Other or unknown: “Duluth BMW Dealership service department repaired a recall thats directly related to an issue due to a water pump leak. My X6 currently has a water pump leak for which they are charging me $1600.00 to repair. However, it is the water pump leak is what causes the potential for the engine to overheat and start the vehicle to catch fire. I purchased my 2020 in 2019 which was the first batch to be made by BMW. Apparently they're stating the X3, X4 and X5. My X6 have this very same issue and BMW have the responsibility to fix this water pump issue. It's not only the X3,4 and 5. Please help me. …”
