A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

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.
