I was driving down the freeway at about 67 MPH when the message "Traction Control Disabled" came on my display & the car immediately went into "limp mode"! By some miracle I was able to muscle the car out of the slow lane, onto the shoulder as I lost my power steering once in limp mode. I waited a few minutes, car started up just fine, so I shrugged it off. Fast forward 1 week later & the same thing happened to me on my way home on a curvy mountain road. The power steering was again non-existent & luckily, there was no one behind me, nor did anyone come around the corner & hit my disabled car. Once again, it started up, no problem; however, this is when the harsh forward thrust started happening, & the transmission seemed to be slipping gears. The RPM's would rev to the 6000 range & immediately fall down to 1500. …

The air conditioning stopped working after working amazing, Traction Control Disabled light keeps coming on, The RPM's would rev up seems like it gets stuck then drops to normal. stabilitrak messages with the ABS warning light lit up, Power steering (or power control) goes limp (at the worse times pulling out in traffic) It's on issue after the other. Once I get one fixed another goes, then we're back to the first one that was replaced that is now not working again. I still have a car payment so I'm without my car more than I'm driving it. I have to save up to get it fixed, and I won't drive it until I know for sure it's good. I was almost killed way to many times in it so to all the issues that GM knows about.
I was driving to the store and my car dinged and a message saying something like service stabilitrack flashed. The car slowed and I pulled over and turned off the car. Eventually I turned the car on and it was back to normal speed but then it sputtered like it was out of gas. That was 2 months ago. I've had it in the shop 2 times and my husband has been trying to replace every part suggested by gm and any other mechanic. The car continues to misfire and turn of at times during driving. This feature makes this vehicle completely unsafe. Any vehicle that simply cuts power should not be on the road as it poses unnecessary risk. Please do something.
Traveling at 70 MPH on a highway Traction control/stabilitrac and engine turn on and acceleration stopped, car wont accelerate causing to cars behind me to start swirling around due to my car lost of acceleration, then pulled over to the shoulder thankfully with no accidents, then turn off car and turn on again and car worked normally for about 100 miles and it did it again.
Vehicle died while taking off from the intersection. Leaving us stranded on a busy highway. Engine had sized but oil has been changed every 5k miles with synthetic. No warning light just shut off and wpuld not restart. With 6 kids in the car
The head front left head light has had to be replaced 3 times in 3 months same for the left turn signal. Another issue I have is each time I put gas in, the car gets stuck trying to turn over Until I pump the gas.
