Lights come on dash and engine loses power

Asked by Melissa Feb 10, 2021 at 10:31 PM about the 2012 Chevrolet Silverado 1500 LT Crew Cab 4WD

Question type: Maintenance & Repair

I have a 2012 Silverado 6.0 v8. Lately, my ABS, traction
control, stability, service 4x4, and brake lights will come on
or flash. At the same time the truck loses power, and the
transmission with not shift right and if the ac is on it will
stop blowing cold. I cannot figure out what the problem is.

Scan for codes. Your truck is probably in limp mode.

Its weird though. It kicks in limp mode when the lights come on. Then goes out when lights go off.
