The manufacturer was not made aware of the failure. The failure mileage was approximately 45,000.

We received a recall notice on our Mercedes stating that over time the bonding in the glass panel and sunroof frame might deteriorate over time and cause the glass to separate from the vehicle. On 02/06/25, my son brought his car into the Mercedes dealership in Lafayette, Indiana to take care of the recall. The service tech signed off on the recall and told him everything was ok. On [XXX], he was driving down the highway and the entire glass part of the sunroof flew off behind him! Luckily there wasn’t a driver behind him. He was very startled and could’ve swerved off the road causing injury to himself or others. If someone was behind him they could’ve been injured or even killed. We called the dealership immediately. The service manager told my husband that they checked the glass on the roof and our car was not part of the recall and there was nothing they could do! Since that day, (one month) we have been trying to get SOMEONE to help us. We have contacted the GM at the dealership, talked to 3 people at Mercedes corporate only to be hung up on once and put on hold for 45 minutes the other time. To this day we are unable to get anyone to address the issue. The NHTSA clearly stated our vehicle is part of this recall yet the dealership is stating the glass number wasn’t listed. Obviously our vehicle is part of the recall considering what happened! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2006 Mercedes-Benz C230. The contact stated that while driving at an undisclosed speed, the vehicle started leaking oil. The check engine warning light was illuminated.

CrashFireInjuryDeath
The car randomly misfires and goes into limp mode with a flashing check engine light. This has occurred on roadways and the vehicle loses all engine power. My engine code, 272920 30 183997272.920, falls into a known range of balance shaft gear problems with this motor. There was previously a settlement by the manufacturer to repair the motor but I was unaware of this settlement before purchasing this vehicle as there was no official recall. I am being told the repair requires pulling the motor out which is quite a high cost. The problem has been confirmed by an independent mechanic inspecting the camshaft timing. There were no other indicators of this failure before the check engine light came on and flashed.

The contact owns a 2006 Mercedes-Benz C230. The contact stated while driving approximately 30 MPH, the transmission failed to shift, and the transmission appeared to be frozen in the 2nd gear. The contact stopped and turned off the vehicle and shifted into park (P); when the vehicle was restarted and shifted into drive (D), the vehicle was lunging and jerking. The contact stated that it was difficult to shift from drive (D) to park (P) or reverse (R), because the vehicle would lunge in the direction the transmission was shifted. The contact stated that the check engine warning light was illuminated. The contact had not taken the vehicle to a local dealer or independent mechanic to be diagnosed or repaired. The contact had researched online and related the failure to the transmission control module sensor. The manufacturer had been informed of the failure. The failure mileage was 131,629.
