Which Chevrolet Trailblazer EXT years should you avoid?
No Chevrolet Trailblazer EXT year stands out. Across the 4 model years old enough to judge, none drew twice the complaints of a typical year (about 225), and none shows an unusual share of fires, crashes or deaths for its age.
How this is worked out: each year is compared with a typical year of the same model, which takes most of the difference in sales out of it, and its share of serious failures is compared with every other car of the same model year, because older cars were complained about differently. A year needs 25 complaints to be judged at all. Complaints are unverified owner reports. Full method →
