What 20 owners told NHTSA about the 2020 Mercedes-benz E-class Wagon

The Engine Electrical harness is completely corroded after only 50,000 miles requiring a 4k+ repair. Oil leaking from the camshaft sensor pushed it way all throughout harness. There are no warnings as it will only be noticeable after doing routine maintenance OUTSIDE of the manufactures warranty. While driving you may lose complete power or slight power loss due to engine misfiring and low system voltage. Warranty company has denied my claim saying that it looks as if the car was in an accident with water damage but the car is pristine and accident free. This is happening to all Mercedes with magnetic camshaft solenoids after doing routine spark plugs. Any movement of the wires will cause damage to the corrosion and then electrical problems. This happened before with previous generations and they recalled the engine to put extensions between the sensors and harness. Unfortunately they did not do a recall for this generation even though the same problem is apparent!

There was smoke coming from from the engine compartment and spontaneous fire started while the car was at a stop light. The car was totally damaged. The car has less than 15000 miles driven. It is still under warranty. Information was sent to Mercedes-Benz USA with a certified mail and immediately via email from the dealership. Also was reported where the vehicle was stored if they wanted to investigate the engine. Benz USA just wanted me to fill out their standard report form. The towing company also told me that they had to tow another Benz not long ago from engine fire.

PLEASE SEE ATTACHED PDF. IT CONCERNS THE TRUNK OPENING AND CLOSING MECHANISM WHICH IS SUPPOSED TO SIGNAL WHEN SOMETHING IS IN THE WAY BEFORE IT CLOSES. THE TRUNK CLOSED WITHOUT WARNING ON MY HEAD. MERCEDES REFUSES TO DISCONNECT THE TRUNK LATCH FEATURE BECAUSE I WILL NOT SIGN A RELEASE, WHICH I WILL NOT DO. SEE ATTACHED INCIDENT REPORT FILED WITH MB.
