This midsized SUV was introduced as a 2002 model. A 4.2-liter, 270-hp inline six-cylinder is the only available engine. The TrailBlazer accelerates enthusiastically and offers a compliant, if slightly jiggly, ride. Its handling, however, is ungainly, with excessive body lean and slow steering. Stability control might help tame the twitchy rear end, but it's not offered. Braking is unimpressive.

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Model Summary
This midsized SUV was introduced as a 2002 model. A 4.2-liter, 270-hp inline six-cylinder is the only available engine. The TrailBlazer accelerates enthusiastically and offers a compliant, if slightly jiggly, ride. Its handling, however, is ungainly, with excessive body lean and slow steering. Stability control might help tame the twitchy rear end, but it's not offered. Braking is unimpressive. The TrailBlazer's interior is mostly quiet, but wind noise is pronounced. Front-seat comfort is only mediocre, and the seat-mounted front safety belts are a nuisance. An extended-length, seven-passenger TrailBlazer EXT is also available.
