I am having the same kind of issue. I changed teh stereo about a year ago. I then lifted the truck 7 inch on 35s and started having issues shortly after. I would get stabilitrak warning and service 4x4 and loss of steering assist and the power steering would go out and loss of throttle control. Chevy told me it was the stereo and they would not work on it unless I put it back to stock. So I did, they said it was fixed. I drove it a few days and took it back to the shop to put the stereo back in because the stock was not working. Issue started up again. Took it back swapped it all back to stock sill have issues. Chevy is still saying it is the aftermarket stereo. So frustrating.
