Recalls and safety actions

Two major safety recalls address moisture ingress and the risk of electrical shorts in the liftgate module. One recall covers 2014–2015 Grand Cherokees where moisture can reach the liftgate control electronics, potentially causing short circuits and a fire risk. The remedy commonly involves installing protective shields to keep water out of the module area. If your vehicle is affected, the dealer must perform the fix. Protective shielding fixes are the official remedy.

Separately, a recall affecting 2014–2016 Cherokees targets a similar rear liftgate electrical issue with a fire hazard risk. More than 132,000 vehicles are affected, and owners are advised to park outside away from structures until the repair is completed. This recall was announced in 2023 with notifications to owners by mid-year. Fire risk recall details.

For the latest status, confirm your VIN against the official recall lists and contact your Jeep dealer. In some cases Jeep notes the recalls were announced on specific dates, and letters are sent to owners with instructions to schedule service. You can expect service to include inspection, sealing, and shield installation to prevent water ingress. For reference, detailed coverage of these recalls and their scope is available in recall coverage articles. Recall overview and safety implications.

Moisture intrusion and electrical shorts

Moisture is the enemy of the liftgate control module. Water ingress can corrode connectors, create short circuits, blow fuses, or trigger erratic behavior that seems to come and go. The most dangerous consequence is a potential fire risk when moisture contacts live electronics.

• intermittent liftgate operation, fuses blowing, melting or sizzling smells, warning lights in the instrument cluster, or the liftgate failing entirely.
• safety first; disconnect the negative battery cable before touching electrical components. Inspect the liftgate area for standing water, corrosion, or dampness around the control module and its connectors. Look for cracked seals around the liftgate glass, weatherstrips, and the module housing. If water is present, this is a sign of a compromised seal or drain blockage.
• apply the manufacturer remedy if your VIN is listed. This usually means installing protective shields to prevent future water intrusion and resealing the rear hatch so water cannot reach the control module. After repairs, thoroughly dry the module area and re-test all liftgate functions. If corrosion has already damaged connectors or the module, replacement is likely required.

Moisture-related issues prompted the recalls described above. If you suspect water intrusion, prioritize a dealer inspection to determine whether a shield installation or module replacement is necessary.

Liftgate does not open or close properly

A nonresponsive liftgate can be caused by a blown fuse, a faulty switch, wiring damage, or a failed actuator. Start with the simplest possibilities before replacing major components.

1. locate the liftgate fuse in the passenger compartment or under‑hood fuse box. Replace any blown fuse with one of the same rating.
2. press the hatch switch and use the key fob. If some controls work while others don’t, the problem may be a switch or wiring harness rather than the actuator.
3. look for frayed insulation, crushed conduits, or heat damage near the hinge area where wires exit the body and enter the liftgate. Repair or replace damaged wiring as needed.
4. listen for motor noise when the button is pressed. A dead actuator means replacement is likely required. If you can access the actuator, verify electrical connectors are secure and replaced if corroded.
5. re-energize the system and perform multiple open/close cycles to ensure the problem is resolved. If the problem persists, a module or more advanced control unit issue may exist.

When fuses or simple switches fail, the fix is straightforward and inexpensive. If the problem is the actuator or the control module, expect professional service or a DIY replacement if you have the right tools and experience. A typical replacement part for the liftgate pulldown motor is described below with typical costs.

Liftgate not opening to full height or stopping early

Partial opening or early stopping can indicate miscalibration, worn linkage, or a failing limit switch inside the actuator assembly.

1. open and close the liftgate several times to reset the mechanism memory. Observe if it consistently stops at the same height.
2. check for bent or damaged hinges, worn liftgate struts, or misalignment that prevents full travel.
3. if accessible, inspect the actuator assembly for loose fasteners or misadjusted limit switches. Recalibration may be possible in some model years via the onboard system or a dealer tool.
4. realignment or replacement of the actuator may be necessary. If a dealer performs the repair, they may reprogram the liftgate control memory to restore full travel range.

Full travel restoration often requires a replacement actuator or professional reprogramming. If the issue persists after a refresh, escalate to a dealer service center to assess the control module and sensor inputs.

Slow, loud, or erratic liftgate operation

Unusual noise or sluggish performance typically signals mechanical wear or electrical supply problems.

1. confirm free movement of the liftgate components. Look for binding or debris in tracks, hinges, and latch.
2. apply a light automotive-grade lubricant to moving linkages and tracks. Remove dirt that could impede smooth movement.
3. verify power supply to the actuator and ensure connectors are clean and secure. A degraded power circuit can cause the motor to strain and produce noise.
4. worn pulleys, bearings, or gears will create grinding sounds. Replace worn parts as needed.

Addressing mechanical wear and ensuring clean electrical connections will often restore smooth operation without a full replacement. If noise persists after lubrication and cleaning, a parts replacement may be required.

Hands-free operation issues

The hands-free open/close feature relies on specific sensor input and correct alignment. When it fails, you may need to clean sensors, recalibrate the system, or replace components.

1. dirt, snow, or moisture on the sensor can interfere with detection. Wipe with a damp microfiber cloth and dry completely.
2. a weak or dead key fob reduces signal reliability. Replace the battery if needed and re-pair as necessary.
3. if the sensor is misaligned or damaged, the system may not respond consistently. Reposition or replace the sensor per service documentation.
4. some models require dealer software to recalibrate the hands-free system. If problems persist after cleaning and battery checks, a module replacement may be necessary.

Hands-free reliability varies by model year and software version. If repeated attempts fail, expect a software update or hardware replacement at a dealership to restore consistent operation.

Actuator and pulldown motor replacement

When the liftgate pulldown motor or actuator wears out, you’ll notice slow movement, insufficient force to hold the hatch, or complete failure to move. Replacement involves mechanical disassembly and electrical connections.

1. sluggish lift, failure to latch, or intermittent operation that corresponds with motor noise or heat buildup.
2. a typical replacement involves removing interior trim, disconnecting electrical connectors, detaching mounting bolts, installing the new motor, and reassembling. This is doable for a mechanically proficient DIYer with proper tools, but many owners choose professional service for reliability and safety.
3. parts plus labor commonly range from about $478–$514, depending on the exact model year and whether the job requires additional seal or wiring work. If you hire a shop, expect some variance based on local labor rates. Estimated replacement cost.

Active duty notes: watch for related wear in the latch and hinge assemblies when installing a new motor to avoid reoccurrence of binding or misalignment.

Fuses, control modules, and wiring checks

Electrical issues frequently originate in fuses, wiring harnesses, or the control module. Start with the simplest checks and advance to module diagnosis if needed.

1. find the liftgate fuse in the vehicle fuse box. If the fuse is blown, replace it with the same rating and test function.
2. examine the loom that runs from the body into the liftgate for cracks, pinches, or insulation damage. Repair or replace as required.
3. a failing liftgate control module can cause intermittent or no operation. If symptoms persist after fuse and wiring checks, module replacement or reprogramming may be necessary.
4. moisture-induced shorts often affect the control module area. Ensure proper sealing and shield installation to prevent recurrence after any repair.

Safety and maintenance best practices

After repairs, verify function comprehensively. Confirm that the liftgate opens and closes with the proper force, stops at the correct height, and that hands-free operation is reliable. Keep seals and weatherstrips clean and intact to minimize moisture intrusion. Park away from structures if your VIN is subject to recall until the service is completed, as advised by recall notices. Regular inspections of hinges, motors, and the wiring harness will help catch problems before they escalate.
