2021 AT4 6.6 - Same Issue!!!! Its at the dealer right now and they cannot find anything wrong with it! Very Frustrating!! Mine randomly opens any time. I hadn't driven it for about 4-5 hours and then I happen to look outside with my kids and the lights blinked and the gate dropped open... crazy! I worry about parking in parking lots now.
This is why I signed up here - hope someone has heard of this. Its been going on for a couple weeks now. Thanks!!
