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 wasnt a driver behind him. He was very startled and couldve swerved off the road causing injury to himself or others. If someone was behind him they couldve 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 wasnt 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)
