What owners report

Our vehicle, VIN [redacted] , is a 2019 Mercedes C300 2 door coupe. We purchased it as a certified preowned vehicle from Mercedes of Bellevue in Washington State last March 2023. We noticed soon after taking possession of the vehicle that the front driver and passenger seat belts were not retracting into the resting place when not in use. We took it to the service department. The service team there told us that it was an "inherent" problem with a series of vehicles including ours and the there was nothing they could do to fix it. We didn't accept this explanation and returned the car to the dealer service department with the demand that it be fixed. In the meantime, I found a NHTSA recall # 21V-032 that addresses the exact issue for this car model within the production dates that it falls. However, a search of the vehicle VIN [redacted] comes up with zero Unrepaired Recalls. …

My 2019 Mercedes-Benz C300 Coupe's front driver seat belt will not fully retract to its stowed position. This creates THREE safety hazards: 1.Passenger Trip Hazard: The extended belt causes difficulty when exiting from the rear seat - passengers can easily trip over the non-retracting belt 2.Door Damage Risk: Belt gets stuck in the door, preventing proper closure and potentially damaging the door or wearing down the seat belt webbing 3.Safety System Failure: A belt that doesn't retract properly may not fully restrain occupants in a crash, compromising the seat belt safety system Dealer Response: My dealership told me this is "out of pocket" repair cost, even though the identical retraction issue exists in 2017-2021 C-Class Cabriolet (A205 platform) vehicles that ARE covered under Safety Recall 21V-032000. …
