Door locking and unlocking when driving

[Falcon4]

2015 Tahoe LT
Intermittent door locking and unlocking when driving. And intermittent inability to lock vehicle after shutting off the engine.
Any ideas as to what causes this?
Thanks,

First, investing any money in replacement parts, I would check all grounds on the truck, including the ground attached to the frame under the driver's seat.

Does it occur when going over a bump, or anything else recognizable as a road condition source?

Why is this in the 2021+ forum?
