The Instrument Panel Cluster (IPC) may display \"Liftgate Open\", a warning light may illuminate even though the liftgate appears fully closed, and an audible chime may be generated at speeds above 8 kph (5 mph). The liftgate cannot be opened using the front interior switch, key fob, Hands Free kick or exterior handle. ● The power liftgate will not open. ● The power liftgate system chimes when trying to operate the liftgate using a Hands Free Entry (HFE) kick while no key is detected in the zone. ● After enabling or disabling the HFE kick or the Power Liftgate Alert feature, the PLGM does not save the changes. ● Vehicle will not start due to a depleted battery. ● The power liftgate latch releases after pressing the exterior handle switch, but the liftgate does not power open. This bulletin involves inspecting and possibly reprogramming the PLGM with the latest available software.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031422-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031422-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11031422","components":[{"id":"structure-body","name":"Body and frame","parent":null},{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"JEEP","model":"GRAND WAGONEER","year_from":2026,"year_to":2026,"match":"exact","vehicle_ids":["2026_jeep_grand-wagoneer"]},{"make":"JEEP","model":"WAGONEER","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
