2012 MERCEDES-BENZ C250 Complaints

CAMSHAFT INTAKE ADJUSTER REPLACED THERMOSTAT SEALS REPLACED CHAIN TENSIONER REPLACED. *TR

THE STEERING WHEEL ,HAS ALUMINUM PLATING OR COVERING, THAT WAS PEELING OFF AND CUT MY FINGER AS I WAS DRIVING, THIS HAPPENED LAST YEAR AND WAS STILL UNDER WARRANTY, AND DEALER REPLACED, THIS IS HAPPENING AGAIN, AND THE DEALER HAS AGREED TO REPLACE EVEN THOUGH THE WARRANTY HAS EXPIRED. I THOUGHT YOU GUYS SHOULD KNOW. *TR

ON MULTIPLE OCCURRENCES THE VEHICLE HAS STARTED TO MISFIRE AT RANDOM TIMES AND SPEEDS RANGING FROM 45-70 MPH RESULTING IN "LIMP MODE" OR A STALLING CONDITION. THE CHECK ENGINE LIGHT COMES ON, BUT WILL NOT BE ON WHEN THE VEHICLE IS RESTARTED. THE DEALERSHIP ON NO OCCASION HAS BEEN ABLE TO DUPLICATE MY CONCERN ALTHOUGH OTHERS HAVE BEEN IN THE CAR TO WITNESS. I FEEL VERY UNSAFE DRIVING THE VEHICLE AS WHEN IT STALLS ON THE HIGHWAY, I LOSE STEERING AND BRAKES AS WELL. *TR

TL* THE CONTACT OWNS A 2012 MERCEDES BENZ C250. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, HE ATTEMPTED TO ENGAGE THE BRAKES BUT IT FAILED TO STOP THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TECHNICIAN DIAGNOSED THAT THE BRAKE VACUUM WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 25,000 AND THE CURRENT MILEAGE WAS 30,000.

THIS WAS NOT AN ACCIDENT, IT IS, IN MY OPINION, A POSSIBLE SAFETY PROBLEM WITH THE VEHICLE - TURBO LAG; THROTTLE LAG; TRANSMISSION LAG. I ALMOST HAD TWO ACCIDENTS DUE TO THE LAG PROBLEMS, AND HAVE ATTACHED A MORE DETAILED ANALYSIS FOR YOUR REVIEW. TURBO LAG: THIS IS THE TIME IT TAKES FOR THE CAR TO GO FROM ITS NATURALLY ASPIRATED POWER TO THE FULL POWER OF THE CAR AT FULL BOOST/ PEAK BOOST IS REACHED RELATIVELY LOW IN THE REVERSE RANGE, BUT IT IS NOT INSTANTANEOUS POWER LIKE A NATURALLY ASPIRATED ENGINE. THROTTLE LAG: THE DRIVE BY WIRE SYSTEM HAS A BIT OF LAG. UNDER CERTAIN CONDITIONS, I MEASURED IT AT .2 OF A SECOND OR SO. WHATEVER THE VALUE, THERE IS ALWAYS LAG THERE, AND WE ARE VERY SENSITIVE TO IT. HOWEVER, DRIVING INS MODE VS E MODE DOES MAKE SOMEWHAT OF A DIFFERENCE. NONETHELESS, THE CAR ALWAYS STARTS OUT IN E MODE WHEN I GET IN AND START THE CAR. WE DIDN'T PURCHASE THE CAR TO ALWAYS DRIVE IN S MODE. TRANSMISSION LAG: THIS I NOTICE SIGNIFICANTLY AND IT IS, IN MY OPINION, PROBABLY THE MOST ANNOYING TO ME. YOU'LL NOTICE THIS WHEN STOMPING THE PEDAL TO THE FLOOR AND THEN DOING THE WAIT... WAIT... WAIT.. DOWNSHIFT. EVEN IF THIS ENGINE WAS RUNNING ONLY ON ITS NATURALLY ASPIRATED FOUR CYLINDERS, THE TRANSMISSION SHOULD RESPOND IMMEDIATELY TO A SURE FOOTED STOMP TO THE FLOOR WITH THE QUICKNESS, AS DOES MY FOUR CYLINDER RAV-4. HOWEVER, THE MB C-250 DOES NOT! IN MY OPINION, YOU CAN RESET THE TCU ALL YOU WANT, THE DELAY WILL REMAIN.
