Got a weird problem here, the automatic lock function on my 06 XLT is going crazy. It works like as designed on the first start up, the locks will automatically engage after hitting 5 mph and stay locked with no problems. The problem starts after I have stopped for any reason (red light, left turn, stop sign) when I take off again I can hear the lock actuators trying to lock the doors again as if the truck thinks it is the first ignition cycle and I am accelerating for the first time. This happens several times on any given trip. Other than that, the locks work as designed. Anyone ever heard of this? Any help would be appreciated. Thanks
