2003 Mercedes Benz S55

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
