What Our Members Are Saying about Chevrolet TrailBlazer Reliability and Durability

Reliability and Durability of the Chevrolet TrailBlazer: Pros
YearBody/PowertrainComment
2008 4dr SUV 285-horsepower 4.2L I6
4-speed automatic 4WD w/low range
Have owned it for better than six months and nothing has had to be repaired.
2008 4dr SUV 285-horsepower 4.2L I6
4-speed automatic RWD
So far this truck gives me no reason to believe it will be any less reliable than my 2002. It tows just as well, and there seem to be many strides from GM to make it better in other areas. So far, so good.
2007 4dr SUV 291-horsepower 4.2L I6
4-speed automatic 4WD w/low range
Our first was a 2003. We only experienced a taillight that was replaced under recall and foam baffles in the front fenders that slid out of place. And knock the playskool interior, but it stands up better than many more stylish competitors.
2006 4dr SUV 291-horsepower 4.2L I6
4-speed automatic 4WD w/low range
A durable vehicle was an important factor in the purchase of this vehicle.
2003 4dr SUV 275-horsepower 4.2L I6
4-speed automatic 4WD w/low range
4 wheel drive gets me through most unplowed roads in winter. Not afraid to drive in one.

The powertrain will last much longer than the rest of the car. Interior wear and random parts failures will leave it undriveable before the engine & transmission quit.
