Mercedes Benz is recalling 54 MY 2009 S-class, W221 vehicles. During production the front and rear passenger side door locks may have been mistakenly interchanged during production. The exchange of a front and a rear passenger side door lock would result in a passenger side door that cannot be opened by merely pulling on the interior handle and a rear door lock that can be opened with a simple pull of the interior door handle even if locked.
Dealers will check the part number on all door locks and replace any incorrectly installed door lock free of charge. The recall began on March 27, 2009. Owners may contact Mercedes Benz at 1-800-367-6372.
