When driving at 40mph a service Stabilitrak warning came up on the dashboard and the power steering immediately turned off making the truck difficult to control. The check engine light also turned on, but there was no prior warning that something was wrong. I was able to pull off the road safely, but would not have been able to execute anything more than a wide turn and if the road wasn't completely straight it could easily have caused an accident. I will take the truck to a dealer tomorrow to have the issue looked at and the truck inspected.

Several times in the last month, while driving at various speeds, the power steering light and the stabilitrak light come on and I loose power steering. Twice this has happened at higher speeds and on a curve, making it very difficult to control the truck. I drove to dealer, but they indicated no codes were present for the check engien light. I explained it was not check engine rather the other two mentioned above. I have had this happen 6 times now, and the quick cure is to shut the truck off and restart. This resets the electronics and the truck is fine until the next time. Lates occurance was 8/23/22.

While driving the truck randomly loses power steering. The display screen states that the anti-lock brake system needs to be serviced. Once I turn the truck off and back on it seems to reset and work as normal. The dealer will not fix due to the truck not having any check engine lights on. This is very frustrating and a safety issue that Chevy needs to look at.

While driving the Colorado without warning and unexpectedly will lose power steering and lock as I’m driving. It has happened over 10 different times and most recently this past Monday 6/6/22 as I was driving and about to make a right turn. It almost caused an accident because my truck couldn’t turn. Two service engine signs will display on the screen and after I pull over and turn off the truck then turn back on, the screen will reset and power steering works again. The Montebello Chevrolet dealer won’t fix it because they said the check engine light is not on. This is an imminent danger on the road and needs to be fixed.
