Power Lift Gate Latch Problems

[tphford]

Has anyone experienced issues for their power lift gate latch not catching and it decides to go back up? It happens all the time with my 2012 Limited. It starts to go down and then just as you think it will latch itself shut it decides something is wrong and gives a warning ding and opens back up. And yes, there is nothing in the way that would trigger the safety feature such as a small child or something to block it. Sometimes it takes 2 or three times and then it will decide to latch itself. Of course you can manually close it but that is no fun.

Thanks!

You could try the procedure in the service manual to "Intialize" the liftgate.....


Power Liftgate Initialization
NOTE: If the power liftgate feature is turned OFF in the message center, the system cannot be activated with any switches or with the liftgate handle. The system will need to be turned ON for any power operation to occur.

NOTE: The power liftgate may not operate under the following conditions:

•A low voltage or dead battery
•A disconnected battery
•Repairs/adjustments have been made to the power liftgate rod, power liftgate motor, liftgate hinges or liftgate striker
If any of these conditions has occurred, the power liftgate must be reset.


NOTE: The power liftgate may also be initialized by carrying out the liftgate/trunk module (LTM) self-test.

NOTE: The battery must be disconnected for 20 seconds before the module will enter the initialization mode.

1. Disconnect the battery.
2.Wait 20 seconds and reconnect the battery.
3.Manually close and fully latch the power liftgate.
4.Power open the power liftgate by using the key fob or control switch.
5.Once the power liftgate is fully open, close the power liftgate by using the key fob or control switch
