What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Mechanical failure, steering jam and brake did not work during driving at 15-[address] got in accident hitting the van.
The contact stated that while her boyfriend was driving, the front and back seat warmers were operating and the driver noticed smoke. The contact mentioned there was a smoke odor and noticed the front driver seat caught on fire.
While on my short commute to work (about 8 minutes) this morning my driver seat started to smoke and burned a hole through the leather and melted part of my clothing.
After 10 minutes of driving on the highway I could smell smoke but thought it was outside the vehicle. A few seconds later I felt a burning sensation on my lower back. I reached my left hand behind me to check and felt something hot, when I pulled my hand out my finger tips were covered in melted leather.
The evening before the fire I had dinner out and when I went to unlock my car doors, the right blinker light flickered and remained on. As I got into the car the sound of the blinker was very quick and I turned it off but realized then that it went completely out along with the right front headlight.
