I have a 2012 Cayenne Turbo. On many occasions, I get out of the car, close the door and then push the button on the outside handle to lock the doors. The doors lock, but the horn does NOT beep twice and the red light inside does not blink. I must reopen the door and relock a couple times for it to beep and arm the alarm appropriately.

Has anyone else seen this behavior? Any suggestions for a fix? thx.

 

anyone? would love to figure this out...
