A body creak sound or rattle may be heard near the upper header by the liftgate hinge on some 2018-2019 XT5 models. The sound or rattle may be caused by the two metal structure panels, located in the rear header, rubbing together. The condition is most often found on the left side of the vehicle.
Pry the two metal structure panels away from each other to eliminate the sound or rattle. Remove both quarter upper trim panels and both center pillar upper trim panels. Lower the rear portion of the headliner only. (Fig. 17)

To separate the two panels at the seam, go through the access hole using a cotter pin tool or similar tool. (Fig. 18) The panel seam is located toward the liftgate opening on a 90° angle. It is not directly above the access hole. (Fig. 19)

Place the tool between the two panels and twist or apply pressure to separate the panels. (Fig. 20)

After the panels are separated, apply any approved metal panel bonding adhesive between the two metal panels. (Fig. 21) Refer to metal panel bonding in the appropriate Service Information.
