I think I have a problem. The first time it happened I just assumed I must have bumped it or obstructed it somehow and didn't notice it reversing back open as I walked away.... No idea if it beeps when interfered with or not (I'll have to try that next time I'm out there). It sat open in relative's driveway ALL NIGHT with luggage and a camera exposed. Nothing stolen or tampered with, luckily. That was 2 weeks ago (and about 2 weeks after delivery). Tonight I KNOW I pushed the button on the hatch and closed it... and I KNOW it was closed, because I walked out for some fresh air and looked at my car from across the parking lot. That was probably 4-5 hours after I parked it and I wasn't close enough for it to recognize the fob. About 4 hours after that I pulled up the App to preheat the car (unseasonably chilly this evening) and noticed it was indicating the trunk lid was open. HUH?? Walked out about 10 minutes later. Sure enough, it was open. I'M GLAD IT WAS NOT RAINING EITHER NIGHT! So what could be the issue?? Stray RF?? Do Teslas typically open their trunks randomly every 2 weeks?? Car is a month old, has tech pkg. Pretty sure I'm not crazy or imagining this but can't figure out how I'd duplicate or demonstrate it for repair. No service center nearby (HOURS away).
