NHTSA Complaint #10899403 — 2012 MERCEDES-BENZ S350

VEHICLE ENTERED LIMP HOME MODE WHILE ENTERING INTERSECTION. DEALERSHIP SAID CODES DID NOT INDICATE AN ISSUE AND COULD NOT REPRODUCE PROBLEM. ONLY ACTIONS TAKEN WAS A COMPUTER TEST AND ROAD TEST. AFTER LEAVING THE DEALER, THE VEHICLE ENTERED THE LIMP HOME MODE AGAIN THIS TIME ON THE HIGHWAY. DEALER THEN REPLACED TWO SENSORS AT THE TURBO. AFTER RETURNING THE VEHICLE TO ME, IT ENTERED THE LIMP HOME MODE AGAIN, ALSO WHILE DRIVING ON THE HIGHWAY. THIS TIME, DEALER REPLACED THE TURBO WHEN IT WAS BROUGHT BACK IN FOR REPAIR. THE VEHICLE STILL ENTERED THE LIMP HOME MODE AFTER THIS REPAIR. SO THE DEALER HAS ALSO REPLACED THE CATALYTIC CONVERTER. PROBLEM STILL PERSISTED AND CAUSED A HOSE TO RUPTURE. THIS WAS REPLACED AND THE PROBLEM STILL PERSISTS AFTER A MONTH OF TROUBLESHOOTING AND PARTS REPLACING.
