“I have a 2008 chevy Avalanche ltz, I have a problem with the dash light coming on with service air bag, wiring by the emergency brake pedal a problem. It happens when it running, stationary, when I start the truck. I took the truck to the dealership and they replaced the air bag and the air bag sensor. The light came back on and comes on intermittently. No fix as of yet. This happens all the time from march to present day still ongoing!!!!”
NHTSA complaint #11040365, filed 2017-10, 157,000 miles“The wire harness under dashboard was rubbing against the emergency brake mechanism and shorted out catching fire. I was lucky to have been stopped and able to put the fire out within seconds resulting in very minimal damage but had I been on the highway the result would have been very different. However it did short out other electronics inside the vehicle such as the rearview mirror putting me out hundreds if not thousands of dollars to repair.”
NHTSA complaint #10597743, filed 2014-06, 80,000 miles“My wife drove the truck to walmart to get a couple of items with her were my son in law and daughter. Once arriving there(approx. 3 mi) they noticed some smoke coming from under the hood. My son in law opened the hood to discover a fire, he then ran into walmart where an employee grabbed a fire extinguisher and put out the fire. After they got home I checked it out and the wiring harness that goes to the mass air flow sensor was completely melted. It was still in all th he factory tie downs and wasn't touching anything that could have chafed it or pinched the wires. …”

For the past month the truck will flicker when I drive but it is un constant.
