NHTSA Complaint #10705233 — 2014 MERCEDES-BENZ CLA250

ACCELERATING FROM AN INTERSECTION AFTER THE LIGHT TURNED GREEN, THE ENGINE BEGAN CHUGGING AND THUMPING. THE CHECK ENGINE LIGHT CAME ON IMMEDIATELY AND THE ECO LIGHT STARTED FLASHING . THE ENGINE STALLED SEVERAL TIMES. WE DROVE STRAIGHT TO THE DEALERSHIP WITH THE CAR. AT EVERY INTERSECTION WITH A RED LIGHT, IT SEEMED AS THOUGH THE CAR WOULD STALL AGAIN. WE DID MAKE IT TO THE DEALERSHIP. THEY KEPT IT FOR THREE DAYS, AND DETERMINED THAT IT WAS A DEFECTIVE MANIFOLD PRESSURE SENSOR. THIS IS THE SECOND TIME THE MANIFOLD PRESSURE SENSOR HAS HAD TO BE REPLACED. IN THE FIRST EPISODE ON OCTOBER 9TH, 2014, THE CAR DIED COMPLETELY AND THE MESSAGE "INOPERABLE" APPEARED IN THE MESSAGE SCREEN. THE CAR HAD TO BE TOWED IN THAT TIME. BOTH INSTANCES REQUIRED REPLACEMENT OF THE SAME SENSOR AND AN UPDATE TO THE SOFTWARE. *TR
