2009 Mercedes-Benz S65 AMG ProblemsRough Running Motor/Lack of Power Due to Coil Pack/Ignition Module Failure
Engine misfires (rough running) and lack of power are commonly caused by ignition coil pack or ignition module faults. Proper diagnoses should isolate the cause and prevent unnecessary replacement of good parts.
High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.
A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
2009 Mercedes-Benz S65 AMG RecallsDoor Locks May Not Operate As Expected
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.
