Liftgate issues? Latch issue?

My lift gate glass keeps opening on its own. When I get in the vehicle, and start it, the lift gate glass will open. Last night I was putting gas in the car and the whole time I was pumping gas the latch kept popping over and over. Could it be a short? Maybe a problem with the keyless remote?

Hello,

Try taking the battery out of your keyless, and access the car without using the fob. See if the issue still exists. This will tell you if it is the fob or something else.
It could be a wiring issue.

Here are few helpful articles about vehicle wiring and testing procedures:

I have attached the wiring diagram (see bellow) for the lift gate as well as actuator replacement procedures for your reference.
Please let me know if you have any questions.

Thank you.
