What can fail
Bolts attaching the rear liftgate strut to the body can crack and fail if they become loose, the strut is over-pressurized, and the liftgate opens and closes frequently.
What the fix does
Dealers will inspect bolts for looseness. Loose struts will be replaced. Tight bolts will be removed, fitted with larger washers, reinstalled, and hand-tightened to proper torque.
