On August 12, 2023, my husband pulled into the E43 into the garage with my two kids. When my son got out of the car, he noticed smoke coming out of the front of the car and notified my husband. He popped the hood and tried to put it out with the fire extinguisher but the smoke got overwhelming and he called 911. Fire department came and put out the fire. After the incident we did a search to see if there was a recall we missed but we only found an article published by Mercedes in December 2021 acknowledging their cars may catch on fire but no recall was done.

I WAS DRIVING IN THE FLORIDA TURNPIKE TRAVELING FROM MIAMI I STOPPED AT A SERVICE STATION TO GO TO THE RESTROOM AND WHEN I CAME BACK MY CAR HAD A FIRE COMING FROM THE ENGINE. I HAD TO GET THE FIRE EXTINGUISHER FROM THE GAS STATION, OPENED THE HOOD AND PUT DOWN THE FIRE. THE VEHICLE WAS STATIONARY AND THE ENGINE WAS NOT RUNNING. MY CONCERN WAS NOT JUST MY SAFETY BUT THE FACT THAT I WAS SO CLOSE TO THE GAS STATION. THERE WAS 0 WARNING AND NO ERRATIC BEHAVIOUR FROM THE CAR BEFORE THIS.

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 2018 Mercedes-benz E-class verdict →
