What 251 owners told NHTSA about the 2017 Mercedes-benz C-class Phev

In October 2024, the rear subframe was replaced due to rust perforation in the area of the suspension arm mounting bracket. I had no warning. The car was in for routine service at Mercedes Benz of New London. It had rusted from the inside out and was considered unsafe to drive by the Mercedes service advisor. I could have had a serious accident! I had no choice but to replace the subframe as it is my only vehicle. Shockingly I learned many others have had this issue with various Mercedes models/years and that Mercedes Benz knows of this serious safety problem and there is a class action lawsuit pending but subframe replacement is not covered under warranty by Mercedes Benz, so the cost was mine to bear.

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.

SINCE I BOUGHT IN FEBRUARY 2017 BRAND NEW 2017 MERCEDES BENZ C300 CONVERTIBLE IN ONE YEAR OF OWNERSHIP I HAD TO BRING MY CAR SEVERAL TIMES FOR SERVICES LIKE, THE CONVERTIBLE TOP WOULD NOT WORK, THE MIRRORS WOULD NOT FOLD, THE STEERING WHEEL WOULD NOT ADJUST, ELECTRONICAL ISSUES LIKE CONNECTING MY CELL PHONE TO THE CAR. ( I HAD THE TOP GOT REPLACED ONLY AFTER COUPLE OF MONTHS AFTER I PURCHASED THE CAR.) TODAY APRIL 27 2018 I COULD NOT START THE CAR IN THE MORNING TO GO TO WORK, THE DISPLAY WAS SHOWING THE KEY IS NOT DETECTED( HAD TO EXIT THE CAR COUPLE OF TIMES, WITH THE KEY AND TRY AGAIN TO START THE CAR UNTIL IT FINALLY WORKED).HAD MY TOP OPEN WHILE WAS DRIVING TO WORK AND ONCE PARKED THE TOP WOULD NOT CLOSE, AND AGAIN HAD TO EXIT THE CAR LOCK UNLOCK AN TRY AGAIN COUPLE OF TIMES BEFORE IF FINALLY CLOSED. I DID RECEIVE A LETTER SAYING THAT THE CAR WAS DEFEFECTED, AND THAT THE AIRBAG ON THE DRIVERS SEET MAY NOT WORK, I'LL ATTACH THE LETTER ( BROUGHT FOR SERVICES) BUT IT'S SEEMS THAT THEY DIDN'T FIX THE PROBLEM. ALSO THE TIRE PRESSURE EVERY COUPLE OF WEEKS IT'S LOW, AND THE DISPLAY WOULD SHOW SOMETIMES THAT THE SEET IS NOT FIRM OR STEADY. I BOUGHT A BRAND NEW CAR TO FEEL SAFE AND DO NOT FEEL THAT WAY.

VEHICLE HAS INSUFFICIENT ELECTRICAL GROUNDING THAT CAN LEAD TO AN INADVERTENT DEPLOYMENT OF THE DRIVER AIRBAG. MERCEDES REFUSES TO INFORM ME OF A DATE THAT THE VEHICLE WILL BE REPAIRED. I WAS SENT A LETTER FROM MERCEDES DATED NOVEMBER 2017 AND THE DEALERS AND THE MANUFACTURE WILL NOT GIVE ME A DATE. I AM UNSURE AS I DRIVE THE AUTO THAT THE AIRBAG WILL DEPLOY CAUSING AND ACCIDENT AND INJURY TO MYSELF. WHY CAN'T THE VEHICLE BE REPAIRED IN A TIMELY MANNER? I AM NOW IN THE 5TH MONTH AND WONDERING IF I AM DRIVING A TIME BOMB.

NHTSA ODI 11053814

WHILE DRIVING THE CARE, I NOTICED THE SEAT BELT LIGHT REMAINED ON DESPITE BEING BUCKLED AND THE PASSENGER AIR WAS NOT SET DESPITE MY WIFE SITTING IN THE SEAT. I FOUND THIS ODD, CONTACTED THE DEALERSHIP FOR SERVICE AND RESEARCHED IF THE CAR HAD A RECALL...THIS CAR DID HAVE A RECALL AND WAS SOLD WHILE IN ACTIVE RECALL STATUS. FEDERAL LAW EXPLICITLY PROHIBITS DEALERSHIPS FROM SELLING A NEW CAR IF A PENDING RECALL HASN'T BEEN PERFORMED. AS, A RESULT, I NO LONGER WANT THIS CAR BECAUSE THE CAR SHOULD NOT HAVE BEEN SOLD UNTIL THE RECALL WAS PREPARED. BUT, MORE SO BECAUSE THE REMEDY TO REPAIR THIS CAR IS NOT UNTIL MARCH OF 2017.
