My trailblazer sprung a major power steering fluid leak. I lost power steering after coming out of a grocery store, it was -10 degrees outside and I used my autostart while inside the store. I came out and did not have p/s and noticed a large puddle under the car. I looked under the hood when I got home, and the high pressure hose disconnected from where the high pressure hose meets the metal tube before entering the rack

About 3 weeks ago I lost power and all dash lights were flashing. Pulled to side and restarted without problem. Yesterday, I had SUV in for new tires and when they went to back out of the bay smoke came from the steering column. When they tried again, the ignition switch is dead, no dashboard lights. Disconnected battery to prevent a fire and am towing to chevrolet dealer.

Within the past 6 months, various electrical and fuel problems have emerged: the fuel gauge no longer functions at all (it always shows "empty"); the A/C works intermittently; the rear A/C and heater do not function regularly; the service engine light is always lit; odd and random issues with the stereo system occur (stations & settings randomly changing on their own, powering on/off by itself, not powering on/off as it should, & only one speaker is working at the moment); the key not releasing from the ignition; engine not turning over to start; battery dying without reason; power steering failure; alt. Gauge dropping; reduced engine power while on the highway (suddenly limiting speed to 20 MPH or less); rear wiper turning on by itself; power seat malfunctioning; rough engine idle; entire instrument panel lighting up; running out of fuel while the gauge indicates that there is ample fuel in the tank; brake lamps not functioning; reduced gas mileage. On 02/25/2013, the controls on the driver's side doors stopped working; the windows will not operate or lock/unlock, the exterior mirrors will not adjust, and the locking mechanism will not work. I have brought the vehicle to the dealership for diagnostic testing at least a half dozen times, and each time no problems were detected, no explanations given, and no remedies suggested! From what I've gathered, there were recalls issued for electrical/wiring problems as well as fuel gauge problems, yet I have never received notice of any such recalls from gm!

While driving at 45 MPH (foot not on the gas, going downhill) the vehicle lost all power. Was approaching a stoplight and brake to stop. After truck came to full stop due to me braking for light anyhow, brake pedal became hard, unable to push down or pump. Stopped at traffic light not knowing what happened since gas tank was full, I shut key (truck) off, and on waited till light turned green, it restarted on the first attempt thank goodness. Why the complete powerfailure while driving at 45 MPH, I have heard this could be onstar related, even though I am not signed up as a customer, if a trailblazer 07 is stolen or in an accident, I heard the onstar features confusion w/ satellite and causes them all to shut down. Don't know if this is true, but something went way wrong, luckily no one was hurt or I'd be suing bigtime. Today is 10-12-12, yesterday got a recall notice in the mail for door/windows/locks problem. They will fix for free however no parts to replace are currently available, really??? Wow.

My 2007 trailblazer lost power during acceleration. On january 22 I took it to the dealer and it took them 4 days for the vehicle to act up so they could get a code. They replaced the powertrain control module. On march 3, 2010 it happened again, the same exact problem, while my wife was crossing a street. The rpms went from 2000 or so down to 5-600 while pushing the gas pedal. I had the truck towed in to dealer and got a loaner car under terms of my warranty. It is now day 6 and they cannot get it to act up again. I called gm customer service hotline and got a case # 71-810026931, but I am being told before they send a technician that can solve the problem I must take it to a second dealership at my cost as well as paying for towing and loner car for the first dealership to release the truck. They told me to drive it until it messes up then goto the dealer to get code. The safety issue is what happens to my family if it acts up in the middle of a turn with traffic coming. There is obviously a problem that the computer isn't recognizing. And because of that my family has to be the guinea pigs before gm will send a technician to solve the problem. My local mechanic seen the problem, the dealership seen the problem and thought they fixed it. What they did was put a bandaid on a cut that requires stitches. I have to put my family in jeopardy and that of whoever hits me so gm can save money and not send the technician. The same problem in just over a month, from losing power to the dealership having problems diagnosing it should send up a red flag that something is wrong and lives are in danger. But that does not seem to be the concern except from me. So I have to pay for a truck that im afraid to drive so gm doesn't lose money sending out a technician when they should be worried about a problem with a truck that could cost someone their life.
