Trailblazer Unreliable
By Jon Illinois on


2003 Chevrolet TrailBlazer EXT LT 4WD 4dr SUV (4.2L 6cyl 4A)


Battery failed in 1st year. Buttons peeling on Premium Bose Stereo. Wind Noise is very bad. Had to install custom deflectors but still have noise. STARTING PROBLEMS**** - Multiple occurrences. Late 2005 and late 2007 - still continuing. Dealer replaced a bunch of stuff in 2005 which did not solve the problem. Finally replaced ignition switch which solved the problem. New ignition problem - not starting in late 2007. Replaced ignition switch but the problem is still occurring. VERY UNRELIABLE. Transmission shifts hard but has not failed yet.

Worst Features

GM Chevrolet needs to recall these vehicles and fix the ignition problems. These problems are well documented on the web.
