THE DAY I PURCHASED THE VAN WHILE STILL AT THE DEALER A WARNING CHIME CAME ON AND NO ONE COULD FIGURE OUT WHAT IS WRONG THEN IT FINALLY WENT AWAY BY ITSELF. THAT HAPPENED SEVERAL TIMES SINCE I PURCHASED IT LAST AUGUST. I TOOK IT TO TWO MERCEDES DEALERS BUT NO USE. I ALSO EXPERIENCED A DRASTIC DROP IN FUEL MILEAGE IT SUDDENLY DROPPED FROM AROUND 19 TO 13.5 MPG AT THAT TIME I NOTICED GRINDING NOISE ALL THAT WAS REPORTED TO THE DEALER. ON 2/27/2015 AT 2:15 AM A LOUD KNOCK ON THE DOOR WOKE US UP THE PERSON WAS AN UNDERCOVER POLICE OFFICER THAT HAPPENED TO BE DRIVING BY TOLD US TO GET OUT OF THE HOUSE BECAUSE THE VAN IN THE DRIVEWAY WAS ON FIRE. BY THE TIME THE FIRE TRUCKS ARRIVED THE WHOLE VAN HAD BURNED AND THE HOUSE ALSO CAUGHT FIRE. *TR
