Thanks

I traded my 09 in for a three letter german car top of the line over the summer. They bought it back after numerous electrical issues. I will never go down that road again, EVER. I might try another brand but never that one.

The sales guy told me, it's due to the cold weather and it will go away. I am not sure whether this problem is related to the problem mentioned in this post or not. I am planing to take it to the local dealer to check it. It could be a steering rack issue.

Rack was replaced and still not there. MBUSA technician came in and tightened everything up so much that the car felt like there was zero power steering.

After he "fixed" the problem, the steering was so tight that the car wouldn't return to neutral and there was zero dead zone between turning left and right. That is, when "trying" to drive you could go left or right, but never straight---the only way to keep a straight line was to constantly make small adjustments in the wheel and zig zag down the road. Turn it a 1/4 inch left and it'd stay there, a 1/4 right and it'd stay there too---never returning to a neutral position--or "straight."

It seems that MBUSA is "fixing" the problem by increasing tension in the steering so much that the car isn't drivable. Either that or they plan on making the cars so dangerous to drive that we either give up or get killed trying.

I am "told" that the car is fixed now and will be delivered tonight. I'm not holding out much hope. I'm afraid that my next stop may be the inevitable attorney letters.

It's time MBUSA came clean, fixed this problem and faced their customers in an honest and completely truthful way. So far the only thing I've seen out of them is a random patch work and jury rigging approach to address this issue.

Perhaps they need more ethics training?

Previous post is ccorrect the new Michelins will solve for about 3,000 miles and then it comes back. However, like the previous poster I also do not believe it is a tire problem. I have had the car aligned, road-force balanced, you name it, it's been done. I beleive it is the design of the car itself and not a function of the newer models electric steering. Very frustrating. Between that, the electronic faults, and numerous other problems MB will not "own", I think it might be time for a change. I've been looking at cars that are far less costly and are better equipped and just as safe. Nothing can match the S in terms of presence and style, and at one point it had a ride quality that was unparalleled. I recently rented a (don't laugh) Cadillac XTS (their new big sedan) and I was blown away. Not an S, but WOW, what a car. Blew my mind that it was made by GM. Embarassing to have people in my S with the vibration/shake in the ride, A/C smelling like mold (since new, been cleaned a gazillion times), and having one of the worst user interfaces (Comand) on the planet.
