Example complaints

Electrical system: “I have driven the car now about 900 miles. At no time has the front end collision/pedestrian warning system given me any warning even though I have nearly rear-ended the car ahead and even though I have it set for the earliest warning possible. Bmw n.a. Assist customer care states that I should receive both visible and audible warnings but also states I have to rely on what dealer says. The dealer- dreyer & reinbold - states the system is working as it should. This cannot be true. …”

NHTSA complaint #11099936, filed 2018-06, 900 miles

Other or unknown: “My husband bought a BMW through the military sales program, had it delivered to the United States, and we took it with us to Germany where we currently live. The car is made to U.S. specifications and I had been driving the car weekly in Germany to keep the battery running while he is away on a deployment. …”

Body and structure: “While driving on a local parkway, our sunroof spontaneously exploded. We were not passing under anything and nothing of any noticeable size struck the car or the sunroof. There was a very loud bang, and when we pulled over, we discovered a large hole in the sunroof. There were shards of glass sitting atop the sunroof cover, which had we not had closed, some of the glass would have fallen into the passenger compartment. A simple google search makes clear that exploding sunroofs are a real danger.”

NHTSA complaint #11373788, filed 2020-11, 52,300 miles

Air bags: “I was rear ended. My airbag did not deploy. I do not think my seatbelt restrained me because I was not sore in that area, but do not remember. My head hit the stearing wheel. I spent 3 months in a neuro-recovery program and still deal with post-concussive syndrome. The car is available for whomever would like to see it. I incurred a closed head injury with significant effects. No one has tried to reproduce the issue, and I'm actually scared that if there is a problem and another accident it's like I don't have airbags. …”
