2019 Mercedes-benz GLC-Class Complaints

The component that failed was the right front differential. My safety and the safety of others was put at high risk as I was driving at 60 mph on the highway and my vehicle suddenly and abruptly reduced speed to about 15mph without any warning. This created an extremely dangerous and potentially hazardous situation as I tried to maneuver my car at this very low speed on the highway in the middle lane safely to the side of the highway. Cars around me quickly maneuvered around me in attempts to avoid my slow moving vehicle and not hit me. The entire experience was terrifying, especially given that the car gave no prior indication of a malfunction. The vehicle had to be towed to Mercedes. I have no real answers from Mercedes as to the cause or why the vehicle did not notify me or why the service light did not go on. The vehicle only had 51,000 miles and is well taken care of.

Sunroof exploded while I was driving. No other cars around me, pretty day, not a very hot day. I’m driving along and suddenly hear a loud POP that sounded like a shotgun going off! I swerved, but thankfully did not leave the road. Shattered glass was contained in the cover of the sunroof as I didn’t have it open at the time. A huge hole is in my roof of my car! I called the dealership who said it was not covered under any warranty although I just got the vehicle in Feb of this year. He said I would have to contact corporate. I contacted corporate who said bring it in for an inspection. At the conclusion of the inspection on 10/8/24, they could not determine if it was a manufacturer defect or outside sources since they could not find a point of impact, because the glass was nearly all gone. I had to get my insurance involved. There was no warning whatsoever. The dealership said no recalls. It just exploded all of a sudden!
