NHTSA Complaint #11475553 — 2011 CHEVROLET SILVERADO 1500

Vehicle door locks activate lock and unlock while simultaneously downshifting the transmission, the engine dies, the dash cluster stops working, engine starts again, dash cluster begins working again. After this occurs, when the vehicle is shut off, there is a loud "pop" sound heard over the speakers and no interior lights. The vehicle may or may not have any cab power. Cycling the ignition provides little to no help. After the vehicle sits for a while, it may or may not start again. The vehicle stereo will randomly change from FM to aux. The a/c panel will flicker and the blower motor will fluctuate. This can also be seen while watching the battery gage on the instrument cluster. It will go from around 14 volts DC to around 9 volts DC and back up again.
