Some 2017-2018 Escalade, Tahoe, Suburban, and Yukon models may require replacement of the power liftgate assist actuator.
Prior to replacing the power liftgate assist actuator, verify the liftgate actuator grommet is properly seated to the sheet metal with no gaps. Any gap between the grommet and the sheet metal could result in water intrusion into the liftgate.
To check the retention of the liftgate actuator grommet, pull down on each of the four corners (Fig. 14, #1) of the grommet individually to see if the clip is secured to the sheet metal or if the grommet pulls away easily. (Fig. 14, #2) Also visually inspect or feel the entire lip seal of the grommet to check for proper seating.

Any grommet issues that are found that may have resulted in water intrusion should be noted on the job card or a Field Product Report should be submitted.
