    The car was parked on my driveway, As soon as i started it, I got a message 'The electronic rear axle differential lock is inoperative' NHTSA previously issued a recall for 2017 C63s AMG models. I purchased this vehicle from Carvana in April 2021 with clean single owner carfax. The manufacture warranty has expired. I have seen lots of posts on Mercedes forum talking about this issue where Mercedes did fix the issue free of cost. Since there is no open recall on my vehicle, I am not sure what to do.

    THIS CAR IS NOT EQUIPPED WITH ENOUGH PROTECTION FOR THE FRONT RADIATORS TO PREVENT DAMAGE FROM DEBRIS. THIS IS A KNOWN ISSUE FOR 2017 AND UP VEHICLES. THE RADIATOR SEEMS TO BE VERY FRAGILE DUE TO THE DESIGN AND THERE HAVE BEEN MANY REPORTS OF THE ISSUE, BUT CLAIMS ARE DENIED DUE TO BEING 'ROAD DEBRIS' BUT MERCEDES-BENZ FAILS TO ACKNOWLEDGE THIS IS A MAJOR ISSUE WITH MULTIPLE CLASSES OF THEIR CARS. MY CAR HAS 27K MILES AND IS JUST OUTSIDE THE WARRANTY PERIOD. THE RADIATOR IS LEAKING IN MULTIPLE PLACES.

    ON MARCH 8, 2018 MY VEHICLE HAS BEEN INVOLVED IN AN ACCIDENT. WHILE DRIVING TO A MEETING THE RIGHT REAR WHEEL OF THE VEHICLE LOCKED UP SENDING THE VEHICLE INTO A 360-DEGREE SPIN. ALL SAFETY FEATURES IN THE VEHICLE FAILED. NO BRAKES, NO AIRBAGS DEPLOYED ON IMPACT. ON OR AROUND OCTOBER 21ST OF 2018. MY VEHICLE IS INVOLVED IN A SECOND ACCIDENT. THE CIRCUMSTANCES OF THE VEHICLE ARE IDENTICAL. WHILE ON MY WAY TO A MEETING THE RIGHT REAR WHEEL GOT LOCKED WHICH SENT THE CAR INTO A 360-DEGREE SPIN. BRAKES, STABILITY CONTROL FAIL, THE CAR ACCELERATED WHILE APPLYING BRAKES, AIR BAGS FAILED TO DEPLPOY ON IMPACT. AFTER THE ACCIDENT I REQUESTED MBUSA TO DISPATCH A SOFTWARE ENGINEER TO HAVE THE ONBOARD ELECTRONICS EXAMINED FOR A POSSIBLE DEFECT. MBUSA ALONG WITH THE MANUFACTURER ARE REFUSING TO HAVE AN ENGINEER SENT. THE DEALERSHIP IS ENGAGED IN DECEITFUL TACTICS IN THEIR COMMUNICATIONS WITH MBUSA LLC. THE DEALERSHIP HAS LIED MULTIPLE TIMES TO MBUSA STATING I AM NOT SHOWING UP TO PRESCRIBED MEETINGS. I HAVE SHOWED ON TIME ON THE DATE THE MEETINGS WITH THE ENGINEER WAS SUPPOSED TO TAKE PLACE AND HAVE A WITNESS. ON THE NIGHT OF THE SECOND ACCIDENT THE VEHICLE WAS BROKEN INTO TWICE. THE DEALERSHIP STAFF HAVE CHANGED THE RIGHT REAR TIRE ON THE VEHICLE TO MAKE IT APPEAR AS THOUGH IT WAS THE TIRE'S FAULT. THE PURCHASE RECEIPT FOR THE TIRE AND THE DOT NUMBERS DO NOT MATCH THE DOT NUMBER CURRENTLY ON A TIRE REPLACED BY THE STAFF. MBUSA ALLEGES IT IS THE TIRES FAULT WITHOUT PROVIDING ANY SCIENTIFIC FACT BASED EVIDEMCE. A YEAR AN A HALF LATER THE ISSUE IS NOT RESOLVED AND EVERYONE IS POINTING FINGERS AT EACH OTHER.
