Example complaints

“On july 2018 Bmw issued an important limited warranty information notice related to this vehicle. Bmw would cover repairs to the front passenger seat occupancy for the srs/air bag system. Unfortunately this warranty repair will not cover my vehicle because the 15 year period does not include my vehicle that was put into service in january 2003. I believe that Bmw should cover any 2003 Bmw Z4 rather than cutting off those made in the prior 6 months. Bmw refuses to cover. The other concern I have relates to the servo motor/electronic steering control unit. …”

NHTSA complaint #11128326, filed 2018-09, 80,500 miles

“Air bag warning light has been on for three years. Have had 3 tests incl lieth Bmw test that verifies it is the passenger side occupancy sensor mat. This defect is a known problem in many Bmw models. Bmw refuses to fix it yet requires me to do these diagnosis (for a fee) over and over. Not only that - they have drastically raised the price to repair to >$1400. I seriously question the safety of the car and feel Bmw uses the issue as an opportunity to make high profits off the safety concerns of its customers.”

NHTSA complaint #10631879, filed 2014-09, 55,000 miles

“On august 1 of this year I received a letter from Bmw stating that there was a problem with the front passenger seat occupancy mat(oc3) for the supplemental restraint system (srs/air bag system) . I made an appointment for the following week and when I got to the dealership they told me my extended warranty had run out in march of this year. When I called Bmw of north america I was told the only way to get it fixed is at my expense. Over the next 2 days I spoke to them 3 different times and they would not pay to fix a safety problem that was in the vehicle when it came off the factory floor.”

“I have a 2003 Bmw Z4 and I am having passenger side airbag issues, there was a recall on certain VIN numbers for such problems. My car does not fit in the VIN numbers but I am having same problem, there should be something I could do.”

NHTSA complaint #10350083, filed 2010-08, 39,000 miles

“The air bag light illuminated and has remained illuminated for over 1 year now. When I called Bmw na to inquire whether this issue was covered under the 04v247000 recall, I was told my VIN was not one of the VIN numbers covered under this recall. However, in light of the numerous similar complaints filed by owners of this vehicle, it is evident that a problem exists with the air bag module of this vehicle. Bmw na nevertheless has responded with the same answer your VIN number is not included in the list of affected VIN numbers. …”
