My wife's 2006 hummer auto door lock system continuously locks and unlocks the doors while driving and causes the warning chimes to sound.
have the same problem?

Possible faulty door lock switch, or the park signal is toggling. The best thing to do would be to monitor data with a scan tool, and determine what is commanding the door locks to change. If you were ambitious enough, you could remove and disconnect the drivers door switch, and see if that changes matters. If it doesn't, I would still recommend the diagnosis with a scan tool.
