On Thursday September 12, 2024, I took my vehicle into the Mercedes Benz of Novi dealership located at 39500 Grand River Avenue in Novi, Michigan to have them diagnose and repair the passenger seat due to the seat bouncing, vibrating and rattling while driving the vehicle. Technicians from dealership took the car out and they noted the passenger seat bounced and vibrated as they were driving the vehicle out for the test drive. Technicians from the dealer stated "there cannot be anything done for the vehicle and to call the manufacturer's Customer Care number." While standing in at the service desk at the dealership, I called the Customer Care number (1‑800‑367‑6372) and documented this issue, and the dealer's response, under Case #[XXX]. The Customer Care representative heard the technicians response and included it in case number noted above (see attached) On Monday, September 16th, the dealership contacted me and advised me to bring the vehicle back in to diagnose the same issue. The vehicle was taken back in on Tuesday September 17th. Upon picking up the vehicle on Tuesday September 17th, I was told that all the vehicles of this particular year, make and model has the same problem and that there is nothing they can do about it. I believe this is an extreme occupant safety concern and should be addressed by the manufacturer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
