What owners wrote
The vehicle has experienced repeated Electronic Stability Control (ESC) malfunction warnings that appear related to a prior GM recall for ESC malfunction codes. These warnings occurred before and after dealer repairs. The ESC malfunction may have affected other safety systems. I was involved in two separate accidents while driving this vehicle, and in both incidents the airbags did not deploy. In one accident, the vehicle struck multiple objects in a frontal collision at significant speed.
1st time engine check light came on had brake control updated. 2nd did auto start and after that truck will not start. After 3 hours can start the truck but brake control traction control ABS were off. Engine has reduce power. Dealer updated the truck and check battery. 3rd time truck will not power on. After jump starting the truck it pops up all of previous message. And running board keep popping in and out and truck will still drain power ebven when off.
