Today I’m working on a GMC Yukon Denali and the rear hatch only comes up about halfway and then it stops and shuts. The rear hatch on this is an automatic hatch and normally should open all the way.
And what I found is causing it is rear hatch struts are getting weak there for stressing out the automatic motor too much. When the motor realizes that it’s working too hard to try and open hatch it shuts the hatch automatically.
So on this one by replacing the rear hatch struts it should fix our problem of it not staying up. This also applies to Chevy Tahoe and Chevy Suburbans with automatic rear liftgate hatches.
