Whilst driving on the highway the engine shut down and lost power steering. Had to pull over on the side of the highway. At high speeds this is troubling. The powertrain and check engine light came on. Waited several minutes and car would restart and be operable but would repeat. Mechanic determined a faulty computer known as the powetrain control module (PCM) or engine control module (ECM). This part was replaced and has fixed the problem.

While traveling at night on a level two-lane highway that carries high traffic rates, the vehicle suddenly lost engine power, began to feel as though the brakes came on, the dashboard lights dimmed, and the traction control symbol started flashing. Vehicles behind me quickly braked to avoid a rear collision, as their headlight beams rapidly changed direction and dipped towards the pavement. Then about 6~8 seconds later the traction control light remained on full illumination, then went out, and the engine speed picked up. As I almost was in a surprise rear-end collision, I took the vehicle to the nearest, open chevrolet dealer the earliest I could get it diagnosed. It turns out the steering sensor was defective and had to be replaced at a cost of $392.00. Surprise power loss and subsequent braking making a dangerous situation at higher highway speeds is what made me get it repaired as soon as possible.

Hello, my name is [xxx] owner of a 2006 chevrolet trailblazer. The issue with my vehicle is that my wife was driving it down a highway in northern michigan, driving at about 45-50 MPH and the vehicle just shut off while driving. When the vehicle shut down she lost power to steer and brakes. If this incident happened in the city or on the freeway this could have been fatal. I called chevrolet and started a claim, the person I talked to couldn't speak much english or understand it as well. I told them what had happened and they wrote back with a entirely different story. They sent me to a local dealership, to get advise. The only thing they could tell me was there is no recall on that switch. All I was trying to do was make chevrolet knowledgeable about the situation. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

My husband and I were traveling home from a weekend out of state. We were coming into chicago traveling towards wisconsin where we live. Just before the first toll booth on i80/i94 traveling at highway speeds, we hit a slight bump in the road and lost all power to the car. We managed to coast the car over from the far left lane of a 5 lane highway to the right shoulder of the road out of harms way. The car was towed to a firestone dealership on a sunday afternoon; we were told after a systems analysis was completed that the car would have to be towed to a gm dealership. The closest was in homewood, il. After gm fixed the car, I asked what would cause something like this to happen. I was told by the dealership, it is something that just happens. Knowing the gravity of what could have happened, this is very upsetting. I really believe the trailblazer should be also noted on the gm recall of autos before another family has to experience what mine did or worse. Thank you

Driving down interstate 79 in pennsylvania at normal speed when my airbag light lit up and my air bag disengaged flashed, followed by more lights on the dash going on, and tracking disengaged flashed, then engine light came on, engine failure flashed as I started moving toward the right hand lane in heavy traffic. Just as I made it to the right lane my power cut out and I was going 20 - 25 MPH in two seconds flat. I swerved to the berm of the road as the four wheeler semi truck that was behind me nearly clobbered me. I inched on the berm at 20 MPH to the bridgeville exit and got to the colussy chevrolet dealer where my car stopped dead in the service dept. First, they thought battery, but the battery was fine. It was ignition switch failure which caused my air bags to disengage and my losing power. I was lucky I wasn't killed!! The cost of repairs was $337 but I was told that my 2006 chevrolet trailblazer was not on the gm recall list, even though I had the exact things go wrong with the vehicles on the ignition switch recall list. And they repaired it the same way, with no guarantee that this wouldn't happen again!!! This is not a "vehicle" recall, it is a "parts" recall and my vehicle had to have the ignition switch replaced. I called the gm ignition switch recall hotline and they escalated my case up and up and everyone said the same thing....they are sorry for my distress, my inconvenience but my vehicle is not on the recall list so they cannot replace the cost to repair my vehicle. Perhaps if the semi truck that was behind me killed me, they might acknowledge my safety concerns for the ignition switch (part) and not my vehicle!!!

I was driving down the freeway when the reduced engine power light came on and I lost acceleration & power. Fortunately, there was no traffic at this point. I was able to drive at a very low speed the remaining quarter of a mile into my work place parking lot. When I pulled into the parking lot and came to a stop my car accelerated and almost hit a wall. I was told by a mechanic that is a throttle body error, and that gm is aware of the issue and not doing anything about it! This is a huge safety concern. And, I see all kinds of complaints all over the internet.

This SUV is nothing short of a rolling hazard. The "check engine" light is on and off, again, for the past 6 days. Tried to start it up this morning and the engine light was on. As soon as I was about to back out of the driveway, the vehicle started to idle in a manner that caused the rpms to crank way up and then plunge until almost shutting the engine down with violent shaking and loud roaring noise. Yesterday, the stabilitrak warnings (2) came on the dashboard - I was only going 3 MPH exiting a parking lot. There was no inclement weather and the road was bone dry. I haven't been able to pick up power and it seems like the more I press on the gas pedal, the slower I go. I live in houston and the traffic conditions really don't allow for a "sudden stop" or loss of power on a freeway where people are traveling at an average speed of 70 MPH. I have had 4 other instances of this "check engine" light in 3 yrs. The dealer isn't much help and gm chevy is no help at all!!!! The tv commercials they run about chevy trucks are "like a rock" are very true. This trailblazer is as useless as a rock.
