The security system engages while driving and the vehicle locks all doors and prevents the windows from opening dash stops working cant tell how fast your going and when you stop the vehicle and shut it off none of the electric locks work or the fob you have to unlock the vehicle manually to get out.
Rear hatch will not open. There is no manual way to open. If there was a accident and you needed to exit rear of SUV you would not be able to get out as there is no manual way to open door. It is electronic and has stopped working. Seems to be a common problem in all Yukon's, tahoe's and escalades. There is not even a button from the exterior that you can push to open door. There is no way to open and GMC does not want to fix unless you pay the $100. 00 to look at it then another $500. 00 to fix, I really think this is a safety issue. It is a bad design not having any manual way to open rear hatch on a SUV.
Rear hatch/lift gate has no manual handle to open. When unlocking power locks rear hatch will not open, there is no way to open lift gate from inside or outside of vehicle. If an accident would happen there would be no way out of rear of vehicle. Rear hatch will not open at all, it is all electronic and will not open. This is a common problem for all gm SUV's. Have contacted GMC and they don't seem to about issue.
