Door Locks May Not Operate As Expected
Body, Interior & Misc., March 27, 2009
RepairPal Expert Overview:
During production, on fifty-four Mercedes S-Class models, the front and rear door locks may have been mistakenly interchanged. This means that a rear passenger could open the rear door with a simple pull of the interior door handle, and the front passenger could not open by pulling on the interior handle. This situation could affect the safe exiting of the vehicle in a crash or protection against the accidental opening of the rear door by a child. Dealers will inspect the part numbers on all door locks and replace any that are incorrect. The recall began on March 27, 2009. The Mercedes-Benz recall number is 2009030001.

Mercedes-Benz S550 4MATIC Reviews
09/20/2012 2012 S550 4 Matic. Second time in the shop. 1st problem - the heated steering wheel didn't work from the beginning had to wait for over a month for a new steering wheel to come. 2nd problem - started at around 7k miles and at least once a week it's loosing power at speeds between 60-80 mph and starts shaking. Took it to the dealer. Transmission problem. Now they are waiting for a new transmission and I am driving a very expensive Chevrolet equinox(rental). In addition to the above, the dashboard is making these clicking/cracking noises even when the car is stopped, folding mirror makes squeaky sound when unfolds. For $110K I wasn't expecting a LEGO.
10/15/2012 Update: Waiting on yet another transmission... that's few weeks after they put a rebuilt transmission in that makes a whining noises.
