NHTSA Complaint #11499904 — 2014 MERCEDES-BENZ C250

On December 14, 2022 at approximately 3:45 pm in rush hour traffic in the high speed lane on i-75 in Bradenton, Fl, the 2014 Mercedes C250 I was driving lost total engine power, traveling from 80mph to 0 in seconds. I had just enough time because of the momentum of the speed I was traveling at to maneuver the car into the breakdown lane adjacent to a median construction site. Had I been traveling in the middle lane there would have been insufficient time to change lanes in heavy, fast traveling traffic and get to a breakdown lane. In other words, we could have been killed. There was no check engine light nor warning lights of any kind. The engine was quiet and there was no engine rattling noise or shuddering prior to the incident during over 7 hours of travel from Marietta, Georgia into Florida. The car had been purchased from a used car dealer in Marietta two days before and had passed the Georgia emissions test on 11/18/22. We had the car towed to a Mercedes Benz dealership 20 miles away in Sarasota. On 12/16/22 Mercedes mechanics deemed the catastrophic engine failure to be due to a broken timing chain (this was confirmed in a conversation12/21 with Mercedes Sarasota Service Manager Jim Foulkrod) and that there was no compression in the engine. Among the codes which came up during Mercedes multi-point inspection was 036562, exhaust cam signal and 34164. Mercedes’ estimate to fix the car was $24,222.13. We declined to move forward with engine repairs. Mercedes was threatening to charge storage fees so the car was donated to the charity, Veteran Car Donations, Heroes on the Water which towed the car on 12/20/22. The car remains with the charity awaiting title transfer information.
