Complaints
2020 MERCEDES-BENZ AMG C43
ID: 2103374STRUCTURE:BODY
On Tuesday, June 24th, 2025, the glass panel located between the windshield and sunroof on my 2020 Mercedes-Benz C43 AMG unexpectedly detached and flew off while driving. This posed a serious safety risk to me and others on the road. There were no prior warning lights, messages, or symptoms before the failure occurred. This appears to have resulted from heat stress weakening the bonding that secures the panel to the vehicle—an issue consistent with NHTSA Recall 23V854000. That recall covers my exact year, make, and model, yet my specific VIN has not been included for reasons unknown, despite experiencing the exact same failure described in the recall notice. The issue was confirmed by Mercedes-Benz of Boston, where my vehicle is currently located. The failed component is available for inspection upon request. The dealer quoted me approximately $2,200 for repairs but declined to cover the cost under warranty since my VIN is not part of the active recall. I have opened a case with Mercedes-Benz Corporate to request full or partial reimbursement, and I am reporting this to NHTSA so that my VIN may be considered for inclusion in the recall.
