Hi guys my hatch in my cayenne, so isn't locking when I close it. The lights stays on and when I drive. The screen has a warning signs of the trunk. Can someone help me out to fix this problem?.

 

If you have the old Cayenne like I do and you are refferring to the glass hatch:
Instead of slamming the door or pushing down on the black handle by the rear wiper, try holding the same handle on the left and right sides with your thumb and one finger and close firm but not slamming it as that may make it bounce. Lock and unlock the car and try again.

It sounds rediculous but I have had this switch replaced under warranty 3 times. Still not catching properly the service manager just showed me the technique and I haven't had the problem again.

Let me know if this worked.
