2024 Mercedes-Benz E-Class Reliability Report

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)

The master central screen as well as the passenger screen that contains all features for radio, navigation, control of reading road signs, climate control and the like go BLACK randomly during the four weeks I have owned the 2024 E Class Mercedes. It will reboot after 2-5 minutes with no lost data. Dealer in Cherry Hill, NJ did major software update not completed at time of purchase. But incident happened after two weeks. Others with this make, year and model have same situations with dealerships not knowing anything. Supposedly, Mercedes knows but a solution may be three months or more. This is a safety issue as if happens at night, you lose all connections even to the cell phone and no speed sign indicator on. You cannot see anything but the driver screen with just the speed you are doing. Cruise control disengages which is using all security systems and navigation map.

I’ve been hearing a creaking noise in the rear when coming to a stop. Independent mechanic inspected it and said the subframe was severely rusted and that I probably should not drive long distances until it is fixed. They researched and said others have had similar issue. Mercedes apparently is aware and offers an “extended warranty.” I have an appointment in two weeks (!) to have it looked at by a Mercedes mechanic. They will pay for the repair/replacement IF warranted. Should be a recall, IMO. Can’t imagine that the part in question, which according to my mechanic, “essentially holds the back of the car together” wouldn’t be an immediate recall. Car has 120k miles on it.

The contact owns a 2024 Mercedes-Benz E450. The contact stated while driving at an undisclosed speed, the "Active Emergency Assistance Imperative" message was displayed. The vehicle was taken to the dealer, who determined that a software update was required. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer, who then diagnosed a failure with the power steering control module (PSCM). The vehicle was repaired, but the failure reoccurred. The vehicle was then taken back to the dealer, who replaced the steering wheel. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 50.
