“In 2010 my trailblazer would not idle or accelerate properly, the mechanic found the primary smog air pump not working. Cost to me $720.00. Next the instrument cluster gauges started jumping around and now the speedometer does not work at all. Estimated cost to me $480.00, I can't afford to fix it.. Thirdly the windshield wipers go on and off without warning. I went to a dealership and a private mechanic and neither could find the wiper problem. Cost to me $68.00 for diagnostic time and lots of danger ahead. …”
NHTSA complaint #10492333, filed 2013-01, 67,000 miles“Ever since 50k on my trailblazer, the fuel gauge was been inaccurate. I will look at the gauge and it will be at 1/2 of a tank and just 20 miles later its at 1/4. Then it might go back up to 1/2. It would go away sometimes and come back but now it is back for sure, and will not go away. I tried another cluster in my trailblazer just to make sure it was not the gauge its self. It must be the fuel gauge sensor in the tank its self. It is getting to be a problem. I have run out of gas twice now. Once while on hill, in a very extremely hilly area in ohio. The second time was on the freeway. …”
