Stabilitrak light comes on intermittently for no apparent reason. Have had brake fluid, brake pads, rotors, sensors and tires replaced. Traction control and ABS checked; all is good. No cel code relating to this issue. Traction control off button doesn?t work once light appears. There is no difference in driving when light is on. Still haven?t figured out what causes it. Battery, power cords, and alternator have both had to be replaced do to issues with the voltage outputs. Now to replace fuse box and ECM due to more voltage output issues. Cel has had no indications of an ECM, fuse box, alternator, or battery problem until they were beyond repair (this also happened with other transfer case leak, loss of reverse gear, and front differential leak) . Cel comes and goes by itself at anytime with no difference in drivability or conditions. Each time it reappeared it?s thrown different sensors and/or circuits failing or high/low voltages including o2, maf, tps, evap system, wheel speed, fuel pressure, oil pressure, steering wheel, gas and brake pedal position, air bag impact, just to name a few. My car has recently started going into limp mode at random due to this electrical issue. Only remedy for this problem is disconnecting the wiring harness and allowing the fuse box and ECM to cool down. And finally, my oil filler tube seal broke and oil was spitting out into engine bay. Coincidentally, my pcv valve tube had also broken, and the tube was hanging loose right in front of the oil filler tube. As a result, pcv tubing sucked up a large amount of oil into the air intake; with no check engine light illumination indicating any problems during the time of failure. My air intake system is nearly ruined (not to mention the $$$ I shelled out in oil) and the wear down on parts has been detrimental to the life of the engine. This car is nothing but a cash cow for gm.

I purchased the vehicle from usados auto sales and the owner told me the car had 185,000 on it. Well after paying cash and waiting 27 days I finally receive the title and it says it has 260,000. The bill of sale he signed when he bought it also stated that the actual mileage wasn't correct. He filed my bill of sale out and didn't inform me or even right back there form he lied to me and said it was 185,000 so I contacted him and he said it was something he overlooked to just write on my bill of sale the actual mileage and I told him no I would you have spent $2500 on a vehicle with 260,000 miles and he refuses to help me. Now the vehicles check engine light is on. It leaking oil and the radio doesn't work and it keeps blowing fuses.

When turn the car off and remove the key from the ignition, there are two speakers that continue to make static noise, whether I have opened the door or not. If I bump or hit the center console it will make the speakers louder or turn off. The check engine light is on for multiple codes, and I have worn out shocks. The shocks should make me feel as if I am gliding, bur I feel and jerk to every bump.

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.

On two occasions now within a two week time frame, vehicle shuts off while driving. Both times I was in motion at approx. 25 to 35 MPH. Get it over to put in park and it does start up so far. I have children and I commute on an extremely busy freeway. What if this failure occurs while I'm moving at 70mph plus? My mechanic has replaced some parts in hopes it was the problem. The check engine light is on/off for months but nothing of a major concern is showing up on the computer. I understand this vehicle has 150k miles but it should not be shutting down while driving. Please help.

We were traveling from spokane, wa to portland, or, when we got to richland, wa the check engine light came on. We stopped and scanned the computer and gave us a code for a faulty pedal sensor. We erased the code and turned the trailblazer on and it came back on in about 10 minutes. We read online that other people that have trailblazer ss are having this issues and there was a recall on the sensor and they are getting theirs replaced. I talked to autonation chevrolet and camp chevrolet here in spokane, wa and they both have heard of the recall and the issue but since it won't show up under my VIN number they will not honor the recall. They won't 100 to 150 to diagnose when it took me 5 seconds and they want us to pay about 600+ dollars for an repair that should be free. I read about the sensor and our truck is doing everything it says it will do. When you are at a light and go to push the gas pedal it boggs down like about to die then lunges forward and shifting hard between gear 1 or 2. Can someone please help us with this and help us get the dealership to work with us. If we continue to drive it an accident could happen any moment. This is a huge hazard!!!

Engine light came on and never went off. Have had in garage 4 times and no one able to fix. I have had every code fixed and cleared but light still stays on. The last time in shop light was off when all codes reset and as soon as I drove it a short distance, light returned. Now light goes on and then off and on again. It can last for days or a short drive. Car runs fine and no one can see to find problem.
