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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Mercedes-benz E-class Wagon verdict →
