C7 auto unlock
2017 GS. Since new, the doors have always unlocked automatically when i approach the car. A couple months ago there were a few times that I had to use the remote to unlock it when I first drive it the morning, but then it would work fine all day after that. More recently, this problem has progressed to the remote not working at all unless I use the actual key to pop the trunk, then suddenly the remote works fine... unless I let the car sit for several hours / overnight. Examples:
Morning: have to use the key to pop the trunk (sets off the alarm), then unlock the doors with the remote, then drive away. Stop at a store, go in for a bit, come back out and it works fine (auto unlock and everything). Go back home. Let it sit a few hours.
Evening: have to use the remote to unlock the doors. Short trip to the store, and it works fine again.
Overnight: car sits in the garage
Morning 2: have to use the key to pop the trunk and can repeat the previous steps.
Thoughts?

I also have a '17 GS, and was having intermittent issues with my fob. Once I replaced the battery that came with the fob, all issues were in the past. Worth a shot if your fob is still with the original battery. Whatever the fix ends up to be, let us know how you make out. Good luck.

By auto-unlocked automatically, do you mean when you touch the door pad to get into the car, it unlocked?
Change the FOB battery in both of your FOBs.
