2017-2020 Nissan Armada Tailgate: Diagnosing Power Liftgate Failures and Loose Bolt Issues
This guide details the most common power liftgate problems, including the frequently reported loose motor bolt, and provides critical checks for buying a used tailgate assembly.
- The most common power liftgate failure is a loose bolt on the motor linkage, a simple mechanical fix that doesn't require replacing the motor.
- Before buying a used tailgate, you MUST verify if your Armada has a power or manual liftgate and if it has a surround-view camera system.
- A used, complete tailgate assembly often costs as much as a new, bare OEM shell. The value is in getting all the included components like glass and electronics.
- A software-related recall (NHTSA 19V-654) exists for the 2018-2019 Armada backup camera; ensure this has been performed if applicable.
Known Issues for the 2017-2020 Nissan Armada Tailgate
The most widely reported issue with the 2017-2020 Armada tailgate involves the power liftgate system. While generally reliable, a specific mechanical failure is common and often misdiagnosed.
Power Liftgate Motor Bolt Failure
Many owners report a condition where the power liftgate makes a whirring or grinding noise when activated, but fails to open or close. The gate may unlatch but will not move up or down on its own. This is frequently caused by a single 10mm shouldered bolt that connects the power liftgate motor's drive arm to the tailgate linkage. Over time, this bolt can vibrate loose and fall out, completely disconnecting the motor from the lift mechanism.
- Symptom: You press the button on the key fob, dash, or tailgate, hear the motor run for a few seconds, but the tailgate does not move. You can still open and close it manually.
- The Fix: The repair involves accessing the motor assembly by removing the interior trim panel on the driver's side of the cargo area. The loose bolt can often be found at the bottom of the cavity. Reinstalling the bolt and torquing it correctly restores function. It is recommended to use a thread-locking compound to prevent it from loosening again. While there was a Technical Service Bulletin (TSB NTB16-071) for this exact issue on the previous generation (2004-2014) Armada, no official TSB has been issued for the 2017-2020 models, though the problem persists.
Backup Camera Recalls
There have been recalls related to the rearview camera system, which is housed in the tailgate. It's important to note these are software issues, not a failure of the tailgate hardware itself.
- NHTSA Recall 19V-654: Affects some 2018-2019 Armada models. The backup camera display settings could be adjusted in such a way that the rear view image is no longer visible, and the system would retain this blank setting. A dealer software update resolves this.
- NHTSA Recall R25D6/R25D5/R25D7: Affects some 2025-2026 models, but is relevant context. A software error in the infotainment system at startup could prevent the rearview camera image from displaying.
Pro Tip: If your power liftgate stops working, check for the loose motor bolt before assuming a more expensive component like the motor or control module has failed. This simple mechanical check can save hundreds of dollars in diagnostic and repair costs.
Symptoms of a Failing Tailgate
Beyond the specific loose bolt issue, other tailgate components can fail. Here are the common symptoms to watch for.
| Symptom | Possible Cause(s) |
|---|---|
| Power liftgate is slow, struggles, or stops mid-travel | Weak liftgate support struts (gas shocks), low vehicle battery voltage, or a failing liftgate motor. |
| Clicking or grinding noise when operating | Failing liftgate motor gears or a disconnected/misaligned linkage arm. |
| Tailgate beeps but does not open/close | An obstruction detected by the pinch sensors, a faulty latch, or the system may need to be reset. |
| Tailgate won't latch or pops open | A broken, rusted, or misaligned latch mechanism. |
| "Tailgate Ajar" warning on the dash | Faulty latch sensor or the tailgate is not fully closed. |
| Rearview camera is black, flickering, or distorted | Damaged wiring harness (especially where it flexes near the hinges), faulty camera, or a software issue. |
Buying a Used 2017-2020 Armada Tailgate: What to Check
Buying a used tailgate is an excellent way to save money, but careful verification is required to ensure you get the right part. The Armada tailgate has several variations.
1. Verify Your Vehicle's Options (Crucial)
Before you buy, you must know which features your Armada has. This is the most common source of purchasing errors.
- Power vs. Manual Liftgate: Does your Armada have a power liftgate button on the dashboard (to the left of the steering wheel) and on the key fob? If not, you have a manual liftgate. The mounting points and wiring are different. A power liftgate shell is part number K010M-5ZWAB, while a manual shell is K010M-5ZWMB.
- Camera and Sensors: Check if your vehicle is equipped with the surround-view camera system or Lane Departure Warning. These systems place additional components in the tailgate, requiring a compatible wiring harness and potentially different mounting points.
Warning: Do not purchase a tailgate based on vehicle trim (SV, SL, Platinum) alone. Options can vary within trims. Physically verify the features on your specific vehicle before ordering a replacement.
2. Physical Inspection Checklist
When inspecting a used tailgate, either in person or through detailed photos:
- Check for Damage and Prior Repairs: Look for dents, deep scratches, and signs of body filler (wavy texture, magnet won't stick). Check the inside seams for non-factory welds or sealant.
- Inspect for Rust: Pay close attention to the bottom edge, the area around the window seal, and where the license plate lights mount.
- Examine the Wiring Harness: Ensure the main wiring harness has not been cut and that all connectors are intact and undamaged. A damaged harness is very difficult to repair correctly.
- Verify Included Components: Is it a complete assembly or a bare shell? A complete assembly should include the glass, wiper motor, latch, lights, and interior trim panel. A bare shell is significantly less valuable and requires swapping all your old components.
Replacement Overview & Difficulty
- Difficulty Rating: 3 out of 5 (Moderate)
- Estimated Time: 2-3 hours
- DIY Feasible: Yes, for mechanically inclined individuals with a helper.
Replacing the entire tailgate assembly is a two-person job due to its weight and size. The basic steps involve propping the gate open securely, removing the interior trim panels, disconnecting all electrical connectors and the washer fluid line, detaching the support struts, and then unbolting the two hinges at the top. Installation is the reverse of removal. Swapping components from an old tailgate to a new shell adds significant time to the job.
Warning: Always disconnect the vehicle's battery before starting work to prevent electrical shorts and to allow the power liftgate control module to reset.

Frequently Asked Questions (FAQ)
My tailgate makes a noise but won't open. Is the motor bad?
Not necessarily. The most common cause is a loose or missing bolt connecting the motor arm to the tailgate linkage. If you can hear the motor running, the motor itself is likely fine. The connection has simply failed. This is a much cheaper and easier fix than replacing the entire motor assembly.
Can I add a power liftgate to my Armada if it has a manual one?
While aftermarket retrofit kits exist, converting to a factory power liftgate is extremely difficult and expensive. It requires the liftgate assembly, motor, control module, wiring harnesses, dashboard switch, and likely programming of the vehicle's body control module. It is generally not considered a practical or cost-effective modification.
Do I need to have a used tailgate painted?
Yes, almost certainly. Even if you find a tailgate from a vehicle with the same factory color, slight variations in paint fade from sun exposure mean it will likely not be a perfect match. For a professional finish, a body shop will need to paint the used tailgate to match your vehicle's VIN-specific paint code.
Can I just replace the weak gas struts on my power liftgate?
Yes. The support struts, or gas shocks, can be replaced independently. If your liftgate is slow to open or struggles to stay up, weak struts are a likely cause. Replacing them is a common maintenance item and much cheaper than replacing the motor. According to RepairPal, the cost for liftgate support strut replacement is between $222 and $239 for a 2019-2020 Armada.
