Hi, I have a 2014 Silverado 1500 LTZ. I just had this happen yesterday and now I'm not sure if I can trust the truck anymore. I was making a slow left turn in the parking lot and all the sudden the electrical system flicked off then back on. Lost power steering and all dash lights just momentarily. The engine did continue to run. The truck is stock. I didn't have the AC going and I'm sure I didn't bump the ignition. I did have the the radio up pretty loud and that might be the only thing that has been different lately. I called the dealership and they want to charge me $90+/hr to just diagnose and they acted like they had never heard of any kind of problem like this. Anybody have any similar problems or ideas to fix? Thanks much
