AIR BAGS

Airbag front message

POWER TRAIN

The Valve body control failed. I took the car into the dealership but upon doing some searching this seems to be a common issue amongst owners of this vehicle/make model. The transmission won't go beyond 5th gear (of 9) so it's is dangerous to drive on the interstate. The car doesn't shift into drive, only shifts into N, the reverts automatically to park. It required the engine shutting on/off multiple times and only then does it go into 3rd gear, causing the vehicle to jump due to missing gears. This issue could leave an owner stranded at any time and cause injury due to the limitations of the gears. It was inspected and confirmed behavior by Mercedes in Durham NC. There were no warning lamps, there were no signs of the issue. The technician did plug it in and was able to read the fault codes but it didn't trigger a light. The appeared first about 45 days ago, and the vehicle was taken in to be looked at 7/21/25.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER

My vehicle goes into neutral while driving which poses a major risk.

VISIBILITY

The contact owns a 2017 Mercedes-Benz GLC300. The contact stated that on several occasions while opening the sunroof, the contact heard an abnormal grinding sound.

POWER TRAIN,AIR BAGS,SEAT BELTS

Vehicle has previous recalls done and still has the same issues with recall. Srs code no air bag will deploy. Dealer ship refused to service vehicle due to miscommunication and I'm driving a defective vehicle without an airbag which could lead to a bad accident waiting to happened. I will like to file a complaint against Mercedes of Richmond for refusing to service my vehicle without a defective air bag and the passenger seat bear latch doesn't retract properly. So I'm currently dealing with 2 huge safety hazard and was denied service due to a miscommunication with Steven Powers (service technician) at Mercedes of Richmond! I will like an investigation done.

POWER TRAIN,AIR BAGS,SEAT BELTS

No incident my vehicle has a front left malfunction service required light and issues with the passenger seatbelt not proper latching. Upon checking I notice my car had previous recalls done. It seems as if the same issues has come about. NHTSA: 18v177- seat belt not retracting properly. NHTSA: 17V627 is related to the steering column switch replacement of clock spring. So if me or a family member was to get into an accident no airbag will deploy! Huge safety hazard!
