I have a 2018 Trackhawk. Less than 500 miles on it. When the vehicle has sat out in the cold (25-35F, for example) for a couple of hours and you hit the start on your key FOB, nothing. Yes, all the doors were locked. Tried a second time, nothing. All I was trying to do is warm up the car from inside a restaurant that we would be leaving in like 5 minutes. Tried a third time and the headlights began flashing, horn was blowing, dash looked like a strobe light at the disco. Finally started after hitting the push button in the Jeep but only after the Jeep finished pitching a fit. Reported to the dealer. They checked the battery under passenger seat. Said it was at 708 (whatever that meant) and said it should be at 715. So they kept for 4 hours, completely drained the battery and re-charged to a full charge. They believed the battery was effected because the car was on the showroom and people constantly getting in and out of the Jeep wore the battery down to a lower state. I even asked them how it lowered if I'd been driving it for an hour at a time plus....???? It should be charged, right? Anyway, they re-charged and off I go. Still......cold FOB start? Maybe. Probably not. This morning I go to the car, hit the unlock button and the lights start flashing, dash is a disco, and screen in truck is turning on and off and on and off all while chimes are going on and off. WTF???? I push start and I get an "uh"....then nothing. Push start again and I get "click click". All while truck dash is spazzing out. Push start a 3rd time and Jeep cranks and dash stops spazzing out. In warm weather (I have a heated garage vs my girlfriend's unheated garage) where I keep my garage at a toasty 65F when it's 30F outside, the Jeep cranks fine. What the heck is going on? Anybody????
