Passenger Rear Door lock acting up

[J5races]

I have noticed several time I can walk up to my locked 2018 Tahoe Premier and open the handle for the read passenger door and it isn't locked, door just opens and horn starts honking.

I locked manually from inside and then door lock doesn't unlock with other doors. playing around it seems to work sometimes and not others.

Is this a known issue that the latch assembly can fail and just replace it? Or could it be some BCM or problem elsewhere in the system?

Thank you

Jon

If you stand next to the door and lock it with the remote and don't hear anything, then there's something wrong with the latch/lock. The computers still think it's locked but it's not if you can open it.
