About one time in ten (although it's fairly random) when I close the charge port door after removing the charge cable it will pop back open after a few seconds. It happens after the "clunk" noise that you hear a second or two after closing the charge port door. After closing it a second time it stays closed. Has anyone else seen this? Not sure it it's relevant but I'm still on 1.15.14 software, and I've seen this behavior pretty much since day one. Sig #088.
