2017 Mercedes-Benz E400 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety Issue. The Chrome on the lever to make the seat move forward to access the back seat has sharp razor blade ridges. It has cut my hand open multiple times as well as my wife and a friend. A lot of blood, this is a serious issue. When I brought my car to the Mercedes Service center the agent told me this is a known problem and he too has cut his hand open on customers cars. This is not from wear and tear, this lever is used in frequently, I see a lot of complaints on the blogs too. Mercedes will not fix it. The Part is only $270 but they want $650 to install it.

report

From owner reports, verbatim

The contact owns a 2017 Mercedes-Benz E400 Coupe. The contact stated that the silver metal coating on the seat release lever was rough and jagged on both driver and passenger sides of the two door vehicle. The contact's son had grabbed the front seat release lever to access the rear passenger’s side seat and cut his hand. The cut was approximately 2-3 inches long. No medical attention was needed. The vehicle was taken to the dealer, and the contact was informed that the failure was common with the vehicle and that the coating was known to peel due to heat. The contact was concerned that the failure occurred as his vehicle was stored in the garage and sustained less heat exposure due to its maintenance/care. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 42,000.
