2019-2025 INFINITI QX50 Tailgate: Decoding Camera Systems and Power Liftgate Failures

Symptoms of a Failing QX50 Tailgate

Problems with the QX50 tailgate are often electronic rather than purely mechanical. Because the power liftgate system is integrated with the vehicle's body control module, symptoms can be intermittent and confusing.

Power Liftgate Fails to Close or Opens Partially

A very common complaint is a power liftgate that opens correctly with the remote or dashboard switch, but refuses to close using any of the buttons. The owner is forced to close the heavy tailgate manually. In other cases, the gate may open or close only part of the way before stopping. This can be caused by several issues:

• Control Module Glitch: The liftgate control module may enter a fault state. Many owners report that a simple 'reboot' by disconnecting the car's 12V battery for 15-20 minutes can temporarily or permanently resolve the issue.
• Faulty Pinch Sensors: Pinch sensors run along the sides of the tailgate opening. If a sensor is damaged or sends a false signal, the system will think an object is in the way and refuse to close the gate as a safety measure.
• Weak Liftgate Struts: The motorized struts can weaken over time, lacking the force to lift or control the heavy gate, causing the system to halt the operation.

Tailgate is Completely Unresponsive

In some cases, the liftgate may seem completely dead, with no response from the key fob, dashboard switch, or the button on the tailgate itself. This could be due to a blown fuse, a failed liftgate control module, or a dead latch motor. Check the fuse first, as it is the simplest fix.

Rear Camera Malfunction or Black Screen

A black or flickering screen when you shift into reverse is a known issue, particularly on 2019 models. This was the subject of a recall and is typically fixed with a software update from an INFINITI dealer. If the camera is still not working after the update, it could indicate a failed camera unit or a damaged wiring harness inside the tailgate.

Buying a Used 2019-2025 QX50 Tailgate: A Step-by-Step Guide

Buying a used OEM tailgate is an excellent way to save money compared to a new part, which can cost nearly $2,000 for the bare shell alone. However, due to the electronic variations, you must be extremely careful to get the correct part.

Step 1: Verify Your Camera System (CRITICAL)

The single most important factor when buying a QX50 tailgate is the camera system. There are two versions, and they are not interchangeable without extensive modifications.

• Standard Backup Camera: Found on lower trims like PURE and LUXE. This system uses a single camera in the tailgate. The OEM part number for this camera is typically 28442-5NA0B.
• Around View® Monitor (AVM): Found on higher trims like SPORT and AUTOGRAPH. This system uses multiple cameras (in the grille, side mirrors, and tailgate) to create a 360-degree top-down view. The rear camera for this system is different. The OEM part number for the AVM rear camera is typically 28442-5NA0D.

When buying a used tailgate, you MUST buy one that came from a vehicle with the same camera system as yours. The wiring harnesses and mounting points are different.

Step 2: Physical Inspection Checklist

Before purchasing, inspect the used tailgate thoroughly:

• Damage: Check for dents, deep scratches, or signs of body filler. Minor paint scratches are okay, but structural damage is a deal-breaker.
• Rust: Inspect the bottom seams and around the window seal for any signs of rust or corrosion.
• Completeness: Does it include the glass, wiper motor, lights, and trim? A more complete assembly will save you time and money swapping parts. Used tailgates on eBay often sell as complete assemblies for around $1,100.
• Wiring: Look at all wiring harnesses and connectors. Ensure they are intact, with no cut wires or broken plastic clips. Damage here can cause endless electrical problems.
• Camera Lens: If the camera is included, check the lens for deep scratches or cloudiness.

Step 3: Why Choose a Used OEM Tailgate?

For a complex part like this, a used Original Equipment Manufacturer (OEM) part is almost always a better choice than a new aftermarket one. Aftermarket tailgate shells are rare for this model, and those that exist often have issues with fitment, leading to poor panel gaps and a finish that never quite matches. A used OEM part was designed by INFINITI for your vehicle, guaranteeing perfect fitment and compatibility, as long as you match the camera system correctly.

Cost Comparison: QX50 Tailgate Replacement

Replacement Overview

Replacing the QX50 tailgate is a complex job best left to experienced DIYers or a professional body shop. It has a difficulty rating of 4 out of 5.

The general steps include:

1. Disconnecting the vehicle's battery.
2. Removing all interior trim panels from the tailgate.
3. Carefully disconnecting all electrical harnesses (for the latch, camera, lights, power struts, etc.) and the rear window washer fluid tube.
4. With a helper supporting the full weight of the tailgate, unbolt the main mounting hinges and the power lift struts.
5. Installation is the reverse of removal. All components from the old tailgate must be swapped to the new one if it was purchased as a bare shell.

After installation, the power liftgate system may require initialization or calibration. The simplest procedure is to manually close the tailgate completely after reconnecting the battery, which often allows the control module to re-learn the position. The height can also be custom set.
