Sounds like your "traction control" system is having issues such as a wheel speed sensor.

Depending on what you have for diagnostic knowledge and tools. You may want to send it in for diagnostics and repair. I can tell you that your vehicle's BCM (Body Control Module) controls these circuits. If it was a t my shop. I would first look for any fault codes. Then through the scan tool, manually command the doors to lock and unlock. Depending on what I find, take a closer look at the master control switch. This is in the drivers door and opens/closes windows and locks/unlocks doors. I'm forwarding you a couple wiring schematics just in case. I don't want to slow you down. FYI under the hood, inside the power distribution box. There is a relay for the tailgate lock/unlock. Any questions please feel free to write back. Good Luck.
