Example complaints

Electrical system: “I was slowing down as I was entering an intersection and there was traffic in front of me. I suddenly lost all power steering and power brakes and struck the car in front of me. None of the occupants of either vehicle was hurt, per police report. On my way to the collision center near home, the cab of the truck filled suddenly with very black smoke, so thick I couldn't see and had to immediately try to pull off the road. By the time I got to the side of the road there were flames in the cab as well. When I finally got out of the truck my clothes were on fire. …”

NHTSA complaint #10662229, filed 2014-12, 120,000 miles

Exterior lighting: “I was driving down the road and all of a sudden my headlights go completely out. No other lights went out I continuously flicked them back and forth and finally my bright lights works to get me home. Next day they work fine again then 2 days later same thing happens. Bulbs fuses all have been changed and no short found. So I look online and seems a lot of people with trailblazer are having the same issues.”
