Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The headlights have failed. All the lights blink while you ride along. The two back doors will not lock or unlock and the front doors are starting to not lock or unlock properly. The items that let you know when a tire is low in air are failing. The last one costing over $100 to fix. I am getting very upset with the electric parts in this Trailblazer. This has been going on since purchase. As a photo I can send you a photo of the vehicle.”
NHTSA complaint #10885231, filed 2016-07, 30,000 miles“As I was driving in my yard I happened to bump the ignition key and the motor cut out and died. This caused me to not be able to turn and avoid bumping a post causing some body damage, but I was able to avoid hitting my friend in the yard because he had moved from by the post a minute earlier. I have had one more time with this problem, but not had a problem since, but I am now experiencing an occasional rough running engine. Could this ignition switch on this year vehicle need to be recalled also?”
NHTSA complaint #10680598, filed 2015-02, 42,679 miles“My blower in my 2005 chevy Trailblazer stopped working. The wires melted together on the resister, melting the entire plug. I have seen where this is a common problem chevy and gmcs have. This is a needed function and if there is a common problem, why aren't these companies doing something to remedy this???!! In one week I found 5 people who have had the same problem with chevys... And I love in a town with only 4k people in it!! I can't imagine the rest of the country!!”
NHTSA complaint #10281578, filed 2009-08, 71,223 miles“While driving at 30 MPH, low beam headlights went out. High beams functioned and fog lamps functioned. Drove app. 5 miles and pulled off road and turned the car off. Turned the car on and the lights still did not function. Left the car for 2 hours and returned. Started the car and lights went on for 1 mile and then went off again. The lights went on again the following day for less than a mile of driving.”
NHTSA complaint #10678191, filed 2015-01, 81,600 miles“The first incident happened as I was in line behind a car at a stop sign, the vehicle just cut off and smoke started coming from the steering wheel. I tried to start it up again but it wouldn't start and was stuck in drive. It was towed and identified as the ignition switch burned. This was back in 2011. Since then, I have had the same problem and replaced the ignition switch four times. The vehicle just stalls and cuts out whenever wherever which is dangerous. …”
