The rear power door may not open or close properly, or make a grinding noise from inside the rear trim panel. If this occurs our technicians recommend to check for loose or damaged hardware at the rear door motor. Replace damaged hardware as required and use bolt retaining compound when reassembling the door motor hardware.

My rear door does not always open when I push the button. I need to open the glass, push the cancel button, then close button, then finally it works.

my lift gate will open properly but then it jerks and starts to close. You have to hold it open to use the trunk. would like to find out how to fix

door motor fastening bracket is VERY thin and flimsy. kids left a blanket in the latch mechanism. when motor tried to shut the liftgate, the torque from the motor bent the everliving schnikey out of attachment bracket. I had to tear the entire rear end interior including seats to get at it. I bent back the brackets and braced the brackets with metal and JB Weld. Fix only lasted 6 months until a shopping bag got in the way of latch mechanism and now its even worse. Going to have to spring the big bucks and buy a new one...but will be reinforcing the brackets of the new one before i put it back.

Wouldn't open, just cycled. Lubricated all the points and that made it work 95% of the time.

Rear Power Door no longer worked because the bolt kept coming out. My friend and I found a longer bolt that fit the threads and the power door has been working great ever since. The original bolt was not long enough... simple repair.

I use to love INFINITY Cars , I will never buy another one . Problems with the Rear Power door when under warranty , the Dealership fixed the problem . No longer under warranty and still same problem . Inaddition, I have other issues on this so called Luxury Car , the suspension. My VIN # was not the one that was on the recall list . Dealership says no problem with suspension , replaced front and back suspension on a car with less then 75,000 miles . Took car back to Dealership ,still not driving correctly , they adjusted suspension level on their computers :(
