TL* THE CONTACT OWNS A 2003 MERCEDES-BENZ S55. WHILE THE VEHICLE WAS IDLING, THE CONTACT WAS INFORMED OF FLAMES UNDERNEATH THE VEHICLE. THE FIRE DEPARTMENT WAS ABLE TO EXTINGUISH THE FIRE. THERE WERE NO INJURIES. A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.
WHEN I START S55 AMG AFTER THE CAR HAD BEEN SITTING OVER NIGHT, I FIND DIFFICULT TO MOVE THE GEAR LEVER FROM P TO R; AFTER A FEW TRIES ONLY IT MOVES FROM PARK POSITION TO REVERSE. THIS PROBLEM DOES NOT APPEAR AFTER DRIVING, UNTIL THE NEXT DAY. NOW I AM SCARED TO DRIVE MY CAR THINKING I'LL GET STUCK WITH THIS GEAR LEVER MOVING PROBLEM, OR SOME UNFORESEEN ACCIDENT MAY OCCUR AS A RESULT GEAR GETTING STUCK. ON GOOGLE SEARCH, I READ SEVERAL MERCEDES OWNERS COMPLAINING ON THIS MATTER, STUCK-PARK-PROBLEM. FEDERAL SAFETY STANDARD REQUIRES YOU TO PRESS ON THE BRAKE TO SHIFT THE CAR OUT OF PARK. IT IS PROBABLY LEFT OVER FROM THE AUDI "UNINTENDED ACCELERATION" DAYS, BUT IT IS HERE IN MY MERCEDES BENZ. ADDING TO THE COMPLICATION IS THE FACT THAT THE SHIFTER IS SUPPOSED TO REMAIN LOCKED IN PARK UNLESS THE PROPER KEY IS IN THE IGNITION. I AM HAVING A HARD TIME GETTING MY CAR OUT OF PARK FROM TIME. ACCORDING TO GOOGLE SEARCH THIS HAPPENS DUE TO A CHEAP PLASTIC BRACKET INSTALLED BY MERCEDES TO LOCK THE GEAR IN PARK POSITION, EITHER BROKEN OR DETERIORATION. THOUGH THIS HAS BEEN HAPPENING SINCE ABOUT 2001 & OWNERS HAVE BEEN COMPLAINING, MERCEDES HAS NOT VOLUNTARILY FIXED THE PROBLEM. DEALER MAY CHARGE CLOSE TO $1,200 TO FIX THIS MANUFACTURING DEFECT; I HAVE ALREADY SPENT $238.05 ABOUT A WEEK AGO FOR DEALER TO REPLACED AND FIX TRANSMISSION ELECTRICAL BUSHING LEAKS, THINKING IT WOULD FIX MY GEAR SHIFT PROBLEM. UNFORTUNATELY, IT HAD NOT FIXED MY PROBLEM. I APPRECIATE VERY MUCH IF YOUR AGENCY TAKE APPROPRIATE ACTION TO GET MERCEDES TO RECALL THEIR VEHICLES AND FIX FREE. I THINK THIS PROBLEM IS VERY SIMILAR TO THE GM'S IGNITION SWITCH PROBLEM, AND IS UNSAFE TO DRIVE A CAR WITH THIS KIND OF PROBLEM. *TR

From owner reports, verbatim
I HAVE BEEN EXPERIENCING PROBLEMS WITH MY VEHICLE GETTING STUCK IN "PARK" AFTER MULTIPLE TRIES (SOMETIMES IN EXCESS OF 30 MINUTES) IT WILL RELEASE ALLOWING ME TO SHIFT INTO REVERSE OR DRIVE. I HAVE NOT BEEN ABLE TO DRIVE MY CAR FOR THE LAST FEW WEEKS BECAUSE OF THIS ISSUE, ONCE AFTER GETTING IT TO SHIFT GEARS I DROVE AROUND THE CORNER FROM MY HOME AND PUT IT IN PARK AT THE STOP SIGN (PRIOR TO TAKING A TRIP FAR AWAY FROM HOME) IT BECAME STUCK AGAIN (OBSTRUCTING TRAFFIC) AND IT TOOK ME OVER 30 MINUTES (AGAIN) TO GET IT TO SHIFT AGAIN, I DROVE BACK HOME! THE PSE PUMP THAT OPERATES THE TRUNK FAILED AND THE TRUNK AUTO RELEASES AND BECAUSE IT WORKS BY HYDRAULICS IT IS DIFFICULT TO OPEN (AND HOLD UP) WHILE ATTEMPTING TO LOAD SOMETHING IN THE TRUNK. THE SUPERCHARGER BEARING WAS FAULTY AND CAUSED IT TO SMELL LIKE SOMETHING WAS BURNING AND I HAVE SPENT IN EXCESS OF $14,000 HAVING REPAIRS DONE ON THIS VEHICLE AND I'VE ONLY OWNED IT FOR NEARLY THREE YEARS. THIS IS MAKING MY "DREAM CAR" DREAM A TOTAL NIGHTMARE!!!!!! *TR
