Mercedes-Benz Recall 21V-032: Seat belts – retractor

Affected: 2017–2020 Mercedes-Benz AMG C43, 2017–2020 Mercedes-Benz AMG C63, 2017–2021 Mercedes-Benz C300. Filed with NHTSA on January 29, 2021, covering about 24,550 vehicles.

The problem

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."

The risk

If the seat belt does not fully retract, the occupant may find the operation of the seat belt inconvenient and not wear it, increasing the risk of injury in the event of a crash.

The fix

MBUSA will notify owners, and dealers will check the retraction function of the front seat belts and adjust the damping foam within the B-pillars, as necessary, free of charge. The recall began February 26, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2021020010.
