I was driving my car was sputtering or trying to shut off while I press the gas and I let go of the gas and it catches and stayed on. I took it to the dealership and they said they found nothing wrong. May 3rd around 12pm im driving on the freeway and as im getting on the express lane going 60 it dies and I couldn't move the steering wheel and I slammed into a guardrail. After doing research my car (vin [XXX] ) had multiple recals from the fuel pump and steering wheel and the dealership never fixed or checked any recalls before selling it to me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

WHILE DRIVING MY 2015 C250 COUPE, I HAD TO BRAKE HARD AS I WAS TRYING TO AVERT STOPPED HEAVY TRAFFIC. WHEN I SLAMMED ON THE BREAKS, THE STEERING WHEEL, COLUMN AND ENTIRE VEHICLE LOCKED UP. I WAS UNABLE TO TURN THE WHEEL ENTIRELY. AS A RESULT, MY VEHICLE SLIDE INTO ANOTHER VEHICLE FROM BEHIND. BECAUSE BOTH THE STEERING AND BRAKES LOCKING, I WAS UNABLE TO MANEUVER THE VEHICLE TO AVOID THE STOPPED TRAFFIC. THE AIRBAGS ALSO DID NOT DEPLOY AS THEY SHOULD HAVE.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Mercedes-benz C-class Hybrid verdict →
