My car has stalled several times, either when I am driving, or when I stop at a traffic light. Rough idling and/or running when stopped at a red light or driving at speeds that wouldnât normally be an issue. Engine stalling or misfiring, and car sometimes have trouble starting up. Loud rattling or vibrating noises from the engine. The check engine light is turned on. I took it to Mercedes Benz Dealership in Brooklyn, NY and was told it is a Balance Shaft problem, and they told me it could cost me about $9,000.00. Further research informs me that the problem should not be ignored, nor repair put off. Also, that failure of the balance shaft leaves the inner components of the engine…

MAY 13, 2019, MY WIFE STARTED THE CAR AND DROVE FOR LESS THAN A MILE WHEN HER DRESS STARTED SMOKING FROM THE DRIVER SEAT THAT WAS ALIGHT. SHE STOPPED THE CAR AND REMOVED OUR 11 MONTH OLD BABY FROM THE BACKSEAT AND CALLED ME. SHE HAS A VIDEO OF THE INCIDENT. I CHECKED ON MERCEDES USA SITE AND FOUND OUT THAT THERE WAS A CLASS ACTION LAW SUITE ON THIS ISSUE. WE WERE NOT NOTIFIED BY EITHER MB OR THE ADMINISTRATOR OF THE CASE. THIS COULD HAVE TURNED OUT DEADLY AS THE BATTERY IS UNDER THE PASSENGER SEAT AND THE FUEL LINES. I TURNED THE CAR ON AND AGAIN , THE SEAT STARTED TO SMOKE. IT IS NOW PARKED IN OUR DRIVEWAY AS MY WIFE AND I ARE SCARED OF PUTTING OUR KIDS IN IT. I CONTACTED MB USA AND THEY…

TAKATA RECALL. I PURCHASED MY 2006 MERCEDES R350 IN 2016 WITH OVER 100K MILES ON IT. WITH THE ENGINE LIGHT ALREADY ON. I USED A SCANNER TOOL FOR AN ACCURATE DIAGNOSIS. AS IT STATED TWO ISSUES. A CRANK SHAFT SENSOR/ CAM SHAFT SENSOR WAS NEEDED. SO I DECIDED AGAINST MY BETTER JUDGEMENT TO FINALIZE THE PURCHASE ANYWAY. NEEDLESS TO SAY, AFTER I CHANGED THE SENSORS THE PROBLEM STILL REMAINS. AFTER DOING A LOT OF RESEARCH AND SPENT UNNECESSARY MONEY, IT WAS BROUGHT TO MY ATTENTION THAT THE PROBLEM IS IN FACT A FAULTY BALANCE SHAFT INSIDE OF THE ENGINE. DUE TO A MANUFACTURING DEFAULT. THAT WAS COVERED MY MERCEDES IN A RECALL AT ONE POINT BEFORE I HAD PURCHASED THE VEHICLE. FOR SOMETHING AS SERIOUS…
