Example complaints

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

“My steering was what I felt as an affected problem. I was subsequently stuck while out with my one year old in the cold 10/31/2024. Eventually the car started again but I had what felt like steering issues (i.e. dragging/shuttering) thereafter. I was told that there were no issues aside from the power steering which completely failed and was replaced. Not until 1 year later when I insisted that the issue continued did the dealership give me an idea of what it could be despite them knowing about the SIB the entire time. …”

“I was having intermittent starting issues. After a starter recall was done, things got worse. Idrive will not turn off and car wont start draining battery. Battery was replaced and car still having idrive and start issues. It would not start after being hot. I was told extended warranty is not covered and that the center console was the problem after diagnostic. They want approximately $3000 to repair. The car will not start at all and the idrive will not shut off. They said it will continue until repaired.”

“How does a known manufacturing defect ( or the factory-filled transfer case oil does not meet BMW specifications.) Not become a safety concern. The wheels have intermittent power from the transfer case. My car showed the concern at 55k miles and the warranty company made me go through another 12 months of the shuddering issue before replacing. When moving from winter to all season tire it became more noticeable. When setting off from a slope my power loss was even greater causing the front wheels to slip from the shuddering power train. This possess a greater risk on loose paving.”

NHTSA complaint #11590613, filed 2024-05

“Transfer case issue which is well known across different BMW vehicles. While driving, reversing , slow parking maneuvers there is a very evident jerking sensation coming from the drivetrain. As if gears within the transfer case are slipping. Potentially dangerous while driving because the transfer case distributes power to the rear axle Issue has been confirmed by a BMW mechanic No warning lights”
