Selected complaints filed with NHTSA by 2006 Chevrolet Trailblazer owners, lightly cleaned up (personal details are redacted by NHTSA).
Brakes failed for no apparent reason around 8:00 am that morning. My friend and I was driving to my home in his 2006 Chevrolet Trailblazer after many stops that morning. We was on the interstate doing 65 MPH. I noticed the traffic ahead approaching and I said "cars" indicating to my friend to slow down. He said "I have no brakes!" We narrowly missed the first cars and while readjusting we came into contact with the driver side of three vehicles rolling us on our side! I broke both my arms escaping thankfully with my life. We had no idea what suddenly and unexpectedly lost brakes. Weeks afterwards I started reading about the stabilitrac and steering sensor on the 1 of many Chevrolet vehicle defect issues. Around that year and I believe was the problem. I have been out of work and tried to explain this to people with no reply. …

While driving at about 60mph my ABS light came on an my car started jerking as the anti lock brakes kicked in. I let up off the gas but as soon as I applied the gas it continued, I then pulled over to turn the engine off I let it sit for about 5 min an started it back up an it was fine. This has happened several times over, an usually when I am going at a higher rate of speed. I would say it has happened at least 10x in the past year.
This has happened to me 4 times in the last year and a half first time at a red light it turned green I was the only car at the light when I hit the gas it felt like someone rear ended me look no one behind me then the rear brakes were locked up I drove it 1/4 of a mile and they unlocked them selves I drove to my dealer told them he looked it up said there was a service bulletin about that took my blazer in for a oil change an I supposed looked at the brakes then about 6 months later the same thing and it felt like some one rear ended me again but no one there behind me..then about a month ago in July the same thing at a red lite and I had 3 senior citizens in the blazer when they all thought some one ran into the rear of me but no one was behind me the rear brakes only stayed locked up maybe 300 yards and then released ..then today at a stop sign 8-16-2012 same thing then all kind of …
Started by truck, the brakes and ABS lights came on, also engine light. After turning off and wait a few minutes, I restarted my truck. Lights were off. I drive approx 33 miles to work everyday. When I arrived to work, as I was parking it sounded like my brakes were grinding and hard to move my truck. It became difficult to drive it, like something was holding it back. When I was leaving to go home, nothing, everything seemed OK. Approx 5 minutes before getting home, I was at a light and when I push the gas to go, the noise came back and it was very hard to get my truck to move. Finally got it home, I told my son what happened, he took it for a drive and nothing. For the next few days only here and there maybe I would hear the grinding noise and hard to move my truck. …
My wife, daughter and myself were driving on idaho state highway 70, a narrow, winding, two-lane road with little to no shoulder, when the motor stopped and ilost all power-brakes, steering etc. I was fortunately able to steer the car over to a wide spot on the shoulder and stop. I was unable to re-start the blazer and called aaa to have it hauled to knudtsen Chevrolet in coeur d'alene, idaho. In another half hour we would have been driving 70 MPH on interstate and the outcome could have been disasterous if the car had failed then in high volume traffic. The next day I was advised by knudtsen that the ignition switch was the problem. I wrote a follow-up letter to the owner and the service manager called a few days later indicating that since my warranty had expired neither GM nor knudtsen could help me with the $268 charge for replacing the switch. …
