Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I am writing to voice a concern about a significant safety flaw with newer model Bmw cars, including my 2015 428I gran coupe. Upon turning on to a major road, the car suddenly failed to accelerate to a speed of more than 10-15mph. With traffic quickly approaching from behind at ~50mph, the oncoming car had to swerve to avoid hitting me due to my loss of acceleration, and we both barely avoided a major accident. …”

“Car would shift without warning to neutral and stall while driving at street and highway speed. Potentially may cause a crash due to sudden loss of speed and power. There has been previous recalls, but the 4 series was not included and should be, as I experienced the same as reported with attached”

NHTSA complaint #11351074, filed 2020-08, 117,540 miles

“There is a ebrake bracket made of plastic underneath the car but that sits above the drive train running from the front to the back parallel to the drivetrain. It's not protected by a heat shield and is only made of thin plastic. My has been replaced three times already and is already needing to be fixed again on a car with only 76k miles. The high temperatures from the exhaust melt the plastic and cause the cable to fall on to the drivetrain. It's only the matter of time before it gets caught in the drivetrain or wraps around causes an accident and serious bodily injury. …”
