Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Bought the 2005 z-4 Bmw used from a dealer in high point nc. Drove it and enjoy driving until the warm weather. The steering sticks to a point of being dangerous. To compensate, I steer to the left and car pulls to the left then I bring the steering back towards the center and feel it sticking so I compensate by steering to the right. The whole time down the highway I fear for my life driving this car. I really had to concentrate to keep the car from steering off the road and I'm sure it appears I'm driving erratically to others on the road. …”
