I have a 2018 and the rattle a started the day I paid off the car. I've already had the car (1700) towed to the dealer because it wouldn't start. It took them 4 days get it going. The first two days they "were charging the battery. It has to be 100%", they said. Strange, the first roadside assister checked and the battery was 100%.
I'm getting ready to trade this in on a GMC Sierra.
