The vehicle caught fire while parked and running in the driveway of my home. There were no modifications, no accident, and no external cause. The fire occurred without warning and posed a serious safety risk to occupants and property. The vehicle was under manufacturer warranty at the time of the incident. The fire caused damages to my house too. There were no warning lamps or messages. Benz has not done an investigation yet.

January 2026 Fire

While backing out of steep driveway, the car computer screen blinked saying "updating" then screen went blank, lost power, I could not brake. We have a row of trees at the back of our driveway that stopped the car ( with damage) or else we would have rolled into our neighbors basement all. Tree limbs poked a hole in bumper, cracked left tail light, and damaged the back hatch. Mercedes is saying User fault. I have been driving for 45 years without a ticket, wreck or causing an accident, and I am not a liar.
