Example complaints

Seat belts: “Both front seat belts on the driver and passenger side fail to retract. Looking up my car model I found the following: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017-2021 C300, 2017-2020 AMG C43, and AMG C63 vehicles. The front seat belts might not fully retract to their stowed position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, Occupant Crash Protection. However my vin number was not marked for the repair and the dealer refused to cover it. I ended up paying for the repair out of pocket for safety.”

NHTSA complaint #11521132, filed 2023-05

Wheels: “In regard to continental tires.the wheels crack at the slightest resistance. The wheels constantly need air placed in them sometimes twice a week. In a year I have had to replace 12 tires due to cracking at the slightest impact. The wheels do not last 50 miles after being flat they are destroyed the minute they hit impact. These are dangerous tires for anyone and these need to be recalled.”

NHTSA complaint #11191483, filed 2019-03, 30 miles

Air bags: “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 complaint #11083593, filed 2018-04

Brakes: “The parking brake won't release sometimes after doing everything that the manual and mercedes benz recommends. I've been stranded for over 30 minutes. I've pulled the brake release for over 10 seconds and put the car in gear and turned if off and on. Twice the parking brake light has come on when driving.”
