Car stops accelerating and shifts into neutral without warning I nearly got hit from behind. I have consulted several other Mercedes vehicle owners and all had the same issue. Two of the other owners stated that this happened on the interstate and was very lucky they were not involved in a collision. Both vehicles were GLC 300. Mercedes does not seem to have an answer to the issue and all previous owners traded vehicles for fear of dying.

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.

Is 12 complaints a lot? They were filed between 2022 and 2026, roughly 3 a year, which is fewer than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2020 has 12 complaints on file, fewer than the 2018 (13). Of the 3 model years of the Mercedes-Benz AMG C43 we cover, the 2017 has the most (23). Older model years have had longer to collect complaints.
