2006 Chevrolet TrailBlazer LS 4dr SUV (4.2L 6cyl 4A)


This vehicle has been in the repair shop for electrical problems 2 times, with only 5600 miles this annoying.The 291 horsepower rating, i think is wrong,more like 200 hp. Gas mileage is 12-14 city and 18-20 highway. Off the line acceleration is horrible,from 0- 40 feels like a go-kart, once you are past 40 mph acceleration is awesome. A Geo Metro can beat this vehicle off the line. Transmission is ok, but I think a 5 or 6 speed would improve performance and gas mileage. G80 rear locking differential is awesome, with this no need for 4wd. Wind noise is horrible at highway speeds, sounds like a window is open. Turning circle is great, better than most cars. Stability control is excellent.

Best Features

Stability control,G80 rear locking differential, turning circle, and exterior looks. Luggage capacity is great. OnStar. Full size spare tire.

Worst Features

Better electrical system, more accurate horsepower ratings, in city driving acceleration is far beyond horrible! Better gas mileage for an engine this weak! Back seat seems to close to the front seats. Make room for 3 car seats in the back, only 2 can fit. Sound system horrible. Better cupholders.
