So the car normally will lock the doors when shifting from P to D and going 5MPH+, this is expected behavior. But for some reason my locks keep -relocking- when I stop (say at stopsign/traffic light) and then continue driving. It doesn't always happen, but it does happen sometimes. The doors all lock/unlock fine, so there are no issues with my actual actuators. The system just keeps locking my doors for some reason...

Anyone run into this issue before?

 

One of your door sensors is malfunctioning or you need to adjust the door striker. With the car on and in park, push out on all the doors to identify the culprit . Then adjust the door striker or replace the door open sensor as needed

 

I second checking the door. I know you said your doors lock/unlock correctly so it might be a separate issue, but it reminds me of when the door sensors got jammed in a funny position because I closed the door on the seatbelt. It'd say I had a door open and wouldn't let me lock the doors with the remote.
