2017 Mercedes-benz Glc-class

Independent service company said the car has a raw fuel smell under the vehicle. Signs of fuel leak at the connection between the high pressure fuel rail / high pressure fuel pump line. Mentioned a recall campaign of 2022030003. That addresses this issue. I contacted Mercedes Benz dealers (2) and they said my VIN does not show a recall. The recall does show up online via an AI search and it is supposed to cover 2016-2020 GLCs like ours. Don't know why this is. Can you help?

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.

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 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.

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.
