Since getting my car about 4 mos ago, the stabilitrak service light & indicator lights would come on, and it put the brake on by its self, the first time it did this, it scared me because I was going about 40 MPH and all of a sudden the brake almost stopped me, it has done this 2 or 3 times a week since, I talked to the Chevy service dept., and they said it was safe to drive as long as I was careful, until I could get it checked out, I didn't have $80 an hr., to do that. On 04/28/14, about 10 pm while driving on wet road, it happened again, going around a slight curve, it put the brake on by its self, causing my vehicle to go into a skid, it went off the road and rolled over several times, its a total loss, thank god no one got hurt. They should not have this kind of equipment on vehicles that does this kind of thing. I hope they will fix this problem before someone gets hurt or killed.
Steering wheel position sensor failure of this sensor can cause assist problems... I belong to a trailvoy club for Trailblazer's and have read that there is several members that have reported problems with this steering wheel position sensor...a quote for repair is around $200 with the sensor cost of another $100, total bill of $300 and when the light stability control comes on it can cause the steering to be eractic, which not only in dangers your life but everyone and every thing in you path!
Whether the car is turned on, or off with or without key in the ignition, it has a small speaker or tweeter that steadily stays making a faint buzz. The center console is very loose, and if you press or knock up against the right side or the back side, it becomes louder and/or quieter. Then while in auto (2wd-4wd^or4wdl) and driving, the transmissions feels to not switch geer at the right time, or from drive to reverse and back to drive it jolts forward or back really hard.
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.
4wd switch no longer lit up to show what it was in (4 options: 2wd, auto, 4h, 4l). Control module changed and now stability control is permanently lit up as well as original problem exists. Other than to continue to change part after part after part and sink thousands of dollars into an undiagnosible problem there doesn't seem to be an answer. Meantime the vehicle is unsafe to drive.
I was pulling out of my driveway turing left and the stablizer light on the dashboard came on . I pulled over shut my car down . And started back up the light was gone when ever I drive and I go 60 MPH my sterring wheel starts shaking and my stablizer light comes on and the vec. Shuts down. All I have to do is make a turn not even quickly and the light comes on.
Head lamps go off at night while driving won't come back on , stabilitrack shuts off an warning bells go off for no reason. Now out of the blue transmission will not work. Only has 1st and 2nd, while driving on any road in town or on. Highway.
Recently, I filled my gas tank & low fuel light warning displayed and low fuel light came on. Since then the check engine light is on steady (not blinking) most of the time. The fuel gauge floats back and forth never really letting you know it's true status. The dealers and public know about this issue- yet Chevy refuses to take responsibility and fix the product. It is frustrating & nerve wracking to never know how much fuel you have at any given time, as well as the constant warning lights/ chimes during driving. This is the second serious issue I have had with this vehicle- just a month before had to repair safety issue of stabilitrak turning on at random, after twice it slowed my vehicle- without warning- on the thruway from 55 MPH to about 20 MPH. …
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. …
