    On XXX, my 2016 Mercedes-Benz GLC 300 was serviced at a Mercedes-Benz dealership for a B Service, including replacement of the rear brake pads and sensor. The rear wheel had to be removed to perform this work. On XXX, approximately 7 days later, my wife was driving the vehicle with our [XXX] son and his friend as passengers when the LEFT REAR WHEEL COMPLETELY SEPARATED from the vehicle while in motion on a public road. A truck was approaching from behind. The family narrowly avoided a serious collision. Police responded to the scene and an officer directed traffic while the vehicle was towed. The lug bolts were recovered from the roadway. The dealership's General Manager later asked me to return the lug bolts, which I did. The vehicle required repair of the wheel and hub assembly at a collision center. I was given no written explanation of why the wheel separated. Separately, after the XXX service I noticed a transmission problem that was not present before. On XXX it became dangerous: coming out of stops at traffic lights and stop signs, the transmission would slip into Neutral instead of engaging Drive, and after several attempts would drop directly into third gear with a hard jerk. This creates a serious risk of being unable to accelerate away from a stop in traffic. I documented this on video and provided it to the dealership. No injuries have occurred, but both incidents were near-misses with a high risk of a crash or injury. I am reporting this so the potential defect and the quality of the safety-related service are on record. I have photographs and video from the wheel-separation scene, the transmission video, the service records, and related documentation available on request.

    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 I
