I have had a significant problem with my back lift door. I pushed the button to open it one day, and it started to open, but only opened 24". Manually I pushed it all the way up so I could access the rear storage compartment. I thought by operating it, I might reset it, but no. I took it to my dealer and he said it was a snap to fix...just fixed it on the computer and it worked fine. So if it happens to you...that's the solution.
