My 2013 Malibu has very serious electrical problems. Radio cuts out. All interior light flicker or go out. Steering locks up. Sometimes there is a no start as if the battery was completely drained. But if you wait a while it starts up. Key gets stuck in ignition as well. I really need help with this please.
I would replace the ignition lock cylinder and switch. All of the problems you describe point to that as the problem. Especially the key getting stuck and the intermittent no starts.
