This problem is such a pain in the a*. The vehicle would power down and sometimes powers back up; other times I have to put the car in park and start it up again. Sometimes I have problems with the stabilitrak activating when I back up into my driveway. There have been many of occasions when I will be backing up into my driveway and the park assist/stabilitrak will activate and take control over the steering wheel. I have injured my wrist a few times because of this. I took the vehicle into 2 Chevy dealerships; the first one said they couldn't find the problem so I took it back to the dealership where it was purchased and they said they replaced the stabilitrak or something of that nature. Now here it is 5 months later and the crap is happening again. WTF am I supposed to do? I run a home daycare where I drop kids off and pick them up. Chevy doesn't even offer a courtesy vehicle to accommodate my loss. I have to damn near beg for a vehicle that's only a five seater; never can I get a vehicle equivalent to the Tahoe. I am ready to throw this damn car back at GM and tell them to keep this piece of sht vehicle. The 2015 model is the worst of it's kind!!!
