What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Speedometer appears to be displaying/indicating inaccurate speed compare to actual speed of the car.
Steering (overall for car and steering wheel) feels very unstable when going over uneven road surfaces or small bumps. This is specially true when driving at speeds higher than 40mph.
Since I took delivery of my brand new mercedes-benz sl-55, I noticed severe pulling to one side to the point that, after more than 15 minutes of driving, I will have to switch arms to continue applying compensating weight on the steering wheel.
