One problem related to battery cable has been reported for the 2003 Chevrolet Trailblazer. The most recently reported issues are listed below.
2003 chevy Trailblazer. Speedometer went out on my vacation to florida. Had about 63,000 miles then. It got stuck at different speeds and stays stuck until my husband disconnects the battery cables. It happens probably once a week. Don't have $600 dollars to fix the cloister problem. Reading about the problem it seems pretty common and chevy should recall it. I've had chevy's all my life but this one is a lemon and wouldn't recommend it to anyone!!! any suggestions? can chevy pay part of it or recall it?? thanks.
