I had this happen a few times and found that the two rubber bumpers midway up the sides can be screwed in and out and I screwed mine out a few turns and that fixed the problem. It seemed to usually happen on a sloped drive or such but not always!

 

Hi,

I am not seeing what you are talking about. are the bumpers on the hatch door itself of to the sides of the car? I see the lower ones but cannot screw them. I see the other two but again I cannot screw them.

So which bumpers are you talking about? pics?

Thanks

 

Hi, Have you tried this?

Park your vehicle and turn it off.
Make sure your Highlander is in park mode and turn off the engine.
Go to the back of the Highlander.
Head to the rear of your vehicle where the liftgate is located.
Press the liftgate button.
Locate the liftgate button under the license plate and press it to open the liftgate.
Let the liftgate open.
Allow the liftgate to fully open. If it was previously set to a different height, avoid forcing it open.
Press and hold the liftgate button.
Press and hold the same liftgate button used to close the liftgate for about 10 seconds.
You should hear four beeps, followed by a pause, and then two more beeps. This indicates that the reset was successful.
Close the liftgate and open it again.
Close the liftgate and then open it once more to ensure the reset has taken effect.
By following these steps, you should have successfully reset your Toyota Highlander’s liftgate.
