I own a 2021 Mercedes-Benz GLC 300. The vehicle developed moisture/condensation in the headlamp, and the affected headlamp subsequently failed. I took the vehicle to RBM of Alpharetta, an authorized Mercedes-Benz dealership. I was advised that corrosion was found in the affected headlamp and that the headlamp assembly requires replacement. On September 8, 2026, the dealership provided a repair estimate of $3,387.33. The vehicle had approximately 84,769 miles. Mercedes-Benz previously issued NHTSA Recall 22V-261 / Campaign 2022050005 for certain 2021 GLC-Class vehicles because headlamp electrical connections may not have been sufficiently watertight, allowing moisture intrusion that could c
My vehicle is experiencing moisture intrusion caused by a defective headlight housing seal. The water intrusion has resulted in a short circuit and failure of the turn signal module within the headlamp assembly. I am aware of NHTSA Safety Recall 22V-261, which addresses a substantially similar defect involving inadequate watertight sealing of the headlamp assembly that can allow moisture intrusion and lead to headlamp electrical failure. My vehicle is experiencing the same type of moisture intrusion and resulting electrical failure described in that recall. Because this failure appears consistent with the known safety-related defect identified by NHTSA, I am requesting that the vehicle and
My 2021 Mercedes-Benz GLC 300 is not currently included in NHTSA Recall 22V-261 / Mercedes-Benz Campaign 2022050005, but my vehicle is experiencing substantially the same defect described in that recall. Moisture/water entered the left headlamp assembly/electrical connection, resulting in condensation/water accumulation and damage/corrosion around the headlamp electrical module/connector. The headlamp system subsequently malfunctioned. Recall 22V-261 describes a condition where the headlamp electrical connection may not be watertight, allowing moisture ingress and potentially causing headlamp failure. My vehicle appears to exhibit the same condition even though my VIN is excluded from the

Authorized Mercedes service center scanned the car, confirming Fault Code P019185 (Rail pressure sensor malfunction / signal above permissible limit value). The dealer applied an Engine Control Module software patch under Mercedes TSB LI07.70-P-078047.Second Incident (53,695 miles): Less than 3,000 miles later, the exact same sudden powertrain failure recurred. The vehicle drastically lost propulsion power immediately after exiting a high-speed freeway, l
