Car would not start under 7F. If sitting outside for more than several hours, the car will not start. All systems will turn on, such as fan blower, lights, radio, bluetooth, etc but car wouldn't click. Car would not jump to start either. Had to be towed to dealer. Dealer couldn't replicate issue unless car sat outside, then they claimed starter had bad spots in it and replaced starter. Car would not start AGAIN in temperatures under 7F. Same exact symptoms as last time. Brake pedal hard as well. The car had to be towed AGAIN to the dealership. This time the inhibitor switch was replaced after dealership replicated the issue. Because the temperatures started to rise we do not actually know if this resolved the issue. We will find out this December or January 2020.
