Everything below is an owner-reported complaint submitted to NHTSA about the 2017 Mercedes-Benz E400, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
Seat pressure sensor for supplemental restraint system (SRS) routinely fails. The system generates and error and disables the front passenger airbag. The condition clears when the vehicle is turned off. Sensors have been recalibrated multiple times. System still routinely fails.

THE CONTACT CALLED MERCEDES-BENZ OF LONG BEACH (2300 E SPRING ST, SIGNAL HILL, CA 90755) WHERE IT WAS CONFIRMED THAT THE PART WAS NOT AVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER HAD EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS NOT MADE AWARE OF THE ISSUE. THE CONTACT HAD NOT EXPERIENCED A FAILURE.

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.

Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
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.
