Which Chevrolet Trailblazer EXT years should you avoid?

On raw complaint volume the 2003 is the weakest year on record, with 313 complaints concentrated in the electrical system. It carries 3 recalls.

Read these numbers with sales volume in mind. A model year that sold in huge numbers naturally accumulates more reports than a rare one, and older cars have had more years to fail. The stronger signal is the severity columns and whether the same component keeps coming up year after year.
