Mercedes-Benz USA (MBUSA) To whom It May Concern, Complaint through your dealer, regional MB and state AG. Going through MBUSA is a waste of time. You would be better off going to Sears and buying a shiny new hammer and banging your head every hour on the hour. A little over a year ago, I Purchase a previously owned 2016 GLC300 from a local DGDG dealership in San Jose CA. for the past few month, I started experiencing a heavy fuel odor generated from the fuel rail and fuel injectors. I initiated a leak detection to verify the above-mentioned defect. I became aware the Mercedes Benz has a major issue with the fuel rail and fuel injectors that caused a safety & emission recall campaign 2022030003 that is launched to replace the fuel rail and fuel injectors on 139 Model Year 2016-2020 that included my car GLC-class vehicle. To my surprise my car VIN number was not listed and flagged in this campaign. According to the campaign issue, a leak may develop between the fuel line and the fuel injectors due to trapped debris from the production process, which could affect the safety and emissions of the vehicle. according to the documents of the campaign, trapped debris might damage the seal between the fuel rail and fuel injectors, which over the life of the vehicle, might result in a fuel leak into the engine compartment. I informed Mercedes Bens that my vehicle fuel rail line and fuel injectors have shown to have a safety manufacture failure. Leaking fuel from this area might contact hot parts of the engine and therefore the risk of fire cannot be ruled out. It seems that the fuel pressure deviation has exceeded the thresholds because the fuel odor is perceptible to me. I had an appointment with Mercedes Benz of Stevens Creek, and they established that my vehicle VIN number was not affected by the recall even though the defects exist on my vehicle. I reached out to Mercedes Benz USA, LLC and filed case # [XXX] but they elected not to take responsibility to repair my ca INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have noticed extreme gas odors in the cabin of my car, the gas odor is so horrific that even when I exit the car either outside or in my garage the odor remains. My car is housed in my garage and I'm very concerned regarding these fumes which fills up my garage because my home is attached. I researched on a web site that there has been complaints and consequently a recall ( 21V961000) ON 12-12-2021 FOR GLC 300,2016, But my vehicle did not receive a recall notice. I am concerned regarding possible fire or illness related to fumes being inhaled.

What component or system failed or malfunctioned, and is it available for inspection upon request? Crank case vent valve malfunctioned 2 years ago and was replaced. Now it is failing again. Reports online from other owners show this part failing about every 2 years / 20k miles. This is not a wear item. Yes it is in my car How was your safety or the safety of others put at risk? It is part of the fuel system so it can potentially damage the car Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has been inspected by the dealer Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There is a check engine light that appears right at failure, not before.

The vehicle needs a new PCV Valve / hose, as well as a new turbo charger

My MB GLC 300 has run out of gas three times. The first two times the car showed it still had 40 miles before fill up and the gas warning light never came on. I took the car in for repair to see if the Fuel level sending unit had stopped working or the float was stuck. The date was March 2020 and at that time the car was under warranty. I was told to make sure I filled up the tank when the fuel indicator reached 100 miles. I was told by the dealer there was nothing wrong and the service department had run a diagnostic. I had never been told that I needed to fill up when a car gauge read 100 miles. Thirty or forty maybe but 100 seemed odd. Two weeks ago I had the gas leak repaired which was the result of the class action law suit. Yesterday I again ran out of gas again. The gas gauge showed 3 bars and 100 miles before next fill up. No gas low warning light came on. I was able to get a friend to bring a gallon of gas so I could drive somewhere to fill up. After I filled the gas tank the gas gauge completely stopped working. The miles to fill up is zero. I have tried resetting the ODM and have checked all the fuses related to the gas tank. This could have been a dangerous situation.
