I have a 2012 Dodge Grand Caravan. If you push the button to make the lift gate open, it will go up. But once it gets all the way open it slams closed. Here's the interesting part. If I hold the door open then push the button to make it close, it engages and closes slow. It will not stay open unless I am holding it open though. Anyone heard of this?

 

When I had issues with our 07 lift gate, it would get stuck open. It was proposed that maybe the module was getting confused and forgetting where it was, and that I should unhook the battery for several minutes. It should relearn itself when power is back and you push the button to make it cycle. That seemed to help, but I also put in new lift struts and it's been fine since. The lift struts should hold it open whether you use the power or not.

 

Yes, I have replace the Liftgate shocks. Are you still covered under the basic warranty?

 

sounds like shocks to me too, get new shocks

 

It could be the liftgate strut-supports (prop rods). You vehicle appears to be still under warranty. Please have your servicing dealer inspect for condition and repair.
