“We drove about 12 miles to a friends, parked in driveway, went inside to visit. In 10-15 minutes was a knock on the door by a neighbor who said your car is on fire .

Insurance tow truck took the car to their lot. The whole back half was badly damaged. Afterwards I found many reports of fires like mine. The portland, oregon mercedes dealer would not talk to us.

“I have a 2008 Smart fortwo, the ignition key is between the seats. At least eight times in traffic, I have accidentally turned the car off by bumping the key fob. The car sits dead in traffic until I can restart it. It has everything to do with the placement of the key. I challenge anyone over 200 lbs to take a hard left turn as in a avoidance maneuver and try not to slide to the right and accidentally kill the engine. Someone is going to die in these small cars.”
