2008 Chevrolet Silverado 1500 acceleration problems

Filed Aug 9, 2022 · Acceleration, Electrical · SC

Vehicle abruptly malfunctioned (lose of power) while sitting at the traffic light during a heavy storm. Fortunately, I turned the vehicle off and restarted it, which gave me enough engine power to get a a safe place. I had the vehicle towed to Love Chevrolet, Columbia, SC. Dealership stated the entire wiring harness needed to be replaced. The replacement cost would be $3500. They also stated the wiring harness for this vehicle has been discontinued and I have to take the vehicle to an electrical shop to be fixed.

The problem was not with the air bag, but the front switch that activates the air bags upon impact. When one or both fail the test when you turn the ignition on, it posts a message saying service the air bag system. There is lots of information regarding this on utube. Apparently this is a common problem. I am an electrician and an electronics tech, I know that the air bags will not activate if the crash is on the side with a bad air bag. I had 2 brake light switches go out, at which time the person behind me,would have no idea, I was braking. The switch is a 2 part switch, one part controls the brake light, the other enables or disengages the cruise control system.

Rapid temporary loss of engine power, doorlocks cycling repeatedly, guages malfunctioning, radio shuts off and turns back on with no preset stations and showing 12:00 on the clock ,cruise control disengages. Once vehicle is shut off, no guages nor lights work...as if there wasn't any battery in the vehicle. Vehicle won't start until dome light is restored on via jumpstarting. Cleaning battery connections and numerous ground wire connections gives short-lived relief from symtoms but problems ultimately return. Chevy dealership diagnosis shows that ground wires have high resistance. Online research shows that tens of thousands of other chevy owners are having similar to exact same problems, yet no recall has been issued. Problem was "fixed" last year and has returned yet again.
