“Purchased a 2003 chevy trailblazer-ext lt in dec 2002 from the dealer, team Chevrolet in pasadena. Since purchasing the vehicle, there's been several recalls, one in particular that keeps recurring are the brake lights keep burning, the dealer changed both units but it keeps burning out. I got tired of taking it to the dealer, so I purchased new bulbs and looked into replacing them myself. …”
NHTSA complaint #10315703, filed 2010-03, 89,500 miles“Continuing failure of rear lighting (back-up, brake, driving, and turn). Typically, I have to replace a bulb about every 6 weeks, and the entire left assembly has been replaced twice since the car was new. Bulbs and sockets melt until they are inoperable. Similar issue with front headlights, although only about once a year. Old bulbs and assembly disposed of, but I'm sure more melted ones will be available soon.”
NHTSA complaint #10383402, filed 2011-02, 5,000 miles“While driving down highway started to hear a banging noise turns out it was my plastic that's above my hatch where my 3 red brake light is it hasn't fallen off yet just loose and flopping around I have read this happens to a lot of trailblazer this should be a safety recall on this and even you guys are aware of the problem the molding which is double sided tape is not a proper use for this the company should have to fix it is it gonna take one flying off and causing a death and major accident before anyone does something?”
NHTSA complaint #10558291, filed 2014-01, 156,000 miles“My right front headlight was burned out, and upon investigation, I discovered that the plug and bulb socket had melted along with several inches of wire. It was repaired after some back and forth discussion with the Chevrolet dealer. I thought this incident was strange, but thought it was a random incident until I read on a web forum that this appears to be a common occurrence.”
NHTSA complaint #10110139, filed 2005-02, 21,178 miles“Every few days when I use the turn signal all lights will flash as if the hazard warning lights have been activated. This is exactly like the GM recall for the 2003 Chevrolet trailblazer however my VIN is outside of the recall.”
