Have you had any reports of the gas tank door not opening on the 2016 XC 90? My doors were unlocked, and I re-locked and unlocked again and it still wouldn't open. Fortunately I had enough gas to get to my dealer, where they got it open. They re-locked and unlocked it from the remote, and not the door. I don't know why that worked, but it did. It may have been that the 20 minutes it took me to get there, it had a chance to warm up from below freezing. I only found one other account of this on the Internet, but I have a feeling there are many more out there.

Thanks!
