Airbag front message

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

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.

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.

The driver mirror and passenger mirror are warping or having some type of melting effect happening to it.

Odometer Fraud. The contact purchased a 2017 Mercedes-Benz GLC43 AMG. The contact stated that while reviewing a Carfax report, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 74,000 and at the time of registration, it was discovered that the mileage was 140,000.

-The malfunctioned component is the Positive Crankcase Ventilation. - Vehicle wanted to stall and did not want to accelerate while in the middle lane on the highway with my family. - Yes it has been diagnosis by certified mechanic - The check engine light turned on at the time of the incident and has been turning on and off ever since.

I was driving and my engine light came on. I ran the code and it came up as P052E which has to do with the positive crankcase ventilation regulator valve. I’ve heard that this part goes out very often on the Mercedes Benz.

Car stalled in traffic due to code P052E PCV regulator valve

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!

Strong gasoline smell coming from the engine bay every morning at start up. I removed protective plastic lining from the under carriage to identify the issue. I identified a lot of gasoline dripping from the top portion of the engine compartment where the High Pressure Fuel Pump is located. There was no warning or check engine lights that alerted of this issue of a gasoline leak. This is very dangerous as it could cause the vehicle to catch fire.
