Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Where should I start? Purchased 03 trailblazer in 2/08 w/only 60,000 miles. Has been in shop 3 months..lost count of costs. A/c and heat not working properly..no hot air; clutch fan replaced; transmission slipping; engine cuts off while at stop-light. Should I go on? You would think w/only 60,000 miles on it--it was just getting broken in. I have never been so disappointed in a truck before..now I am stuck with the truck and its payment...no more money to repair and can't afford to trade in.”
NHTSA complaint #10243198, filed 2008-09, 60,000 miles“Dt: left driver's side outside mirror is not holding the correct settings, and clicks constantly. The mirror is hitting against something, and turns completely to the ground. When using keyless entry the mirrors also turn to the ground. The mirror is changing by itself, and it is not going back to the correct setting. The mirror is always making a clicking noise and it is facing downward. There is no problem with the right side. The dealer replaced the right side mirror, and from then on the left side has not worked. Consumer has taken vehicle to dealership 4 or 5 times to be checked. …”
