I have a 2013 Silverado 4.8. It’s only happened a couple times but while driving the truck will make a beep sound and the traction control and stabilitrak both turn off for a couple seconds and then both turn back on. Everything is running fine and doesn’t seem to run any different when it happens. Was thinking speed sensor or something might be off but not too sure. Anyone have this issue??

 

you'll need to have the diagnostic system scanned.

 

See if you can trigger it on purpose by making sharp turns (U turns work best). Try both left and right turns multiple times since the problem is intermittent. If you can duplicate it this way, the steering wheel angle sensor need to be replaced. It’s mounted at the base of the column - takes an hour or so to replace depending on your skill set.
