2019 INFINITI QX30 Tailgate: Decoding Camera Systems and Replacement
This guide details the critical differences between the standard and Around View® camera systems to ensure you buy the correct used tailgate for your 2019 QX30.
- The most critical factor when buying a used tailgate is to match the camera system: either the standard RearView Monitor or the optional Around View® Monitor (360-degree camera).
- A blank backup camera screen may be caused by a software glitch covered under NHTSA recall 19V654000, which requires a free dealer update.
- Replacement is a two-person job and will likely require professional camera calibration by a dealer to ensure the on-screen guidelines and 360-degree view are accurate.
- When inspecting a used tailgate, pay close attention to the wiring harness for any cuts or damage, as this can be very difficult to repair.
Variant Differences: The Camera System is Key
Before buying a replacement tailgate for a 2019 INFINITI QX30, you must first identify which camera system your vehicle has. There are two possibilities, and they are not interchangeable. Installing the wrong tailgate can result in a non-functional camera system.
- Standard RearView Monitor: This is the base system. It uses a single camera located on the tailgate to show what is directly behind the vehicle.
- Around View® Monitor (AVM) with Moving Object Detection: This is an optional, premium system that provides a virtual 360-degree, bird's-eye view of the vehicle. It uses four cameras in total: one in the front grille, one under each side mirror, and one on the tailgate.
Pro Tip: The easiest way to know which system you have is to put the car in reverse. If you only see the view from the back, you have the standard system. If you see a split screen with the rear view on one side and a 360-degree top-down view on the other, you have the Around View® Monitor.
The tailgate shells and camera components are different for each system. For example, the camera for models 'With surround view' is part number 28442-5DA1A. Always confirm which system the donor vehicle had before purchasing a used tailgate assembly.
Symptoms of Failure
Aside from obvious physical damage from an accident, tailgate failures are typically electrical. Common symptoms include:
- Tailgate Will Not Open or Latch: The electronic latch actuator may fail, preventing the tailgate from opening with the handle or key fob, or from locking securely when closed. Sometimes this can be caused by a control module issue that can be reset by disconnecting the battery for several minutes.
- Rear-View Camera Malfunctions: A black screen, flickering video, or a 'No Signal' message can indicate a failed camera, a damaged wire in the harness, or a software issue.
- Rear Wiper Inoperative: The wiper motor inside the tailgate can burn out, leaving the rear wiper stuck in one position.
- Warning Lights: A 'Tailgate Ajar' warning may stay illuminated on the dash if the latch sensor fails, even when the gate is fully closed.
Known Issues, TSBs, and Recalls
There is a significant recall that affects the 2019 INFINITI QX30's backup camera system.
- NHTSA Recall 19V654000: This recall addresses a software issue where the backup camera display settings can be adjusted so the rear view image is no longer visible, and the system retains this blank setting. This can create the symptom of a failed camera, but the cause is software, not a bad part. The fix is a free software update performed by an INFINITI dealer.
- Technical Service Bulletin ITB19-002c: This bulletin notes that if the Display Control Unit (DCU) is replaced, it requires specific configuration using a dealer diagnostic tool. For the QX30, the replacement DCU must also be registered to the vehicle. This is important because a camera issue could be misdiagnosed when the root cause is the DCU.
Buying a Used 2019 QX30 Tailgate: What to Check
A used OEM tailgate can be a great value, as it often comes as a complete assembly with glass, lights, and other components. However, careful inspection is critical.
Warning: The single most important step is to verify camera compatibility. Get the Vehicle Identification Number (VIN) of the donor car and have an INFINITI dealer confirm its original options, or have the seller send clear photos of the camera system in operation before you buy.
- Inspect the Shell: Check for dents, deep scratches, or waves in the metal that indicate previous bodywork. Run a small magnet along the surface; if it doesn't stick in some areas, it may be due to thick body filler.
- Check the Wiring Harness: Carefully inspect the entire wiring harness that runs from the tailgate into the vehicle body. Look for any cut wires, damaged connectors, or shoddy electrical tape repairs. A damaged harness is a major red flag and can be very difficult to fix properly.
- Verify Included Components: Ask the seller exactly what is included. A 'complete' assembly should ideally include the glass, wiper motor, camera, high-mount stop lamp, and latch. If you have to transfer your old components, the price should be significantly lower.
- Inspect the Glass: Check the rear window for any cracks, deep scratches, or signs of delamination around the edges. Ensure the defroster grid lines are not scratched or broken.
- Look for Water Damage: Check inside the bottom of the tailgate for any signs of rust, water stains, or corrosion, especially around the electrical connectors for the lights and latch.
Replacement Overview & Difficulty
Replacing the tailgate is a moderately difficult job that requires two people due to the weight and bulk of the part.
- Difficulty: 4 out of 5
- Time: 2.0 - 3.5 hours (plus painting and calibration)
- Process: The general steps involve disconnecting the battery, removing all interior trim panels from the tailgate, disconnecting the electrical harness and washer fluid hose, and carefully supporting the tailgate. Then, unbolt the gas support struts and the main hinge bolts. Installation is the reverse, but requires careful alignment to ensure even panel gaps and proper sealing.
Calibration Required: After installing a new or used tailgate, the rear-view camera system, especially the Around View® Monitor, may need to be calibrated by an INFINITI dealer or a qualified auto electronics shop. Without proper calibration, the on-screen guidelines may be inaccurate or the 360-degree view may be distorted.

Frequently Asked Questions (FAQ)
How do I know for sure if I have the standard or Around View® camera?
When you shift into Reverse, look at the main display. If you see only one image from the rear of the car, you have the standard system. If the screen splits to show the rear view AND a simulated top-down, 360-degree view of your car, you have the Around View® Monitor.
If I buy a used tailgate in a different color, does it need to be completely repainted?
Yes. To get a perfect color match and finish, a body shop will need to remove all components (lights, handle, emblems), prep the surface, and repaint the entire tailgate. They will then blend the clear coat into the adjacent quarter panels to ensure a seamless look. Expect to pay several hundred dollars for a quality paint job.
Can I reuse my old camera, lights, and wiper motor on a bare tailgate shell?
Yes, in most cases you can transfer your existing components to a new or used tailgate shell. This can be a cost-effective option if you are buying a bare, undamaged shell. However, be aware that the process is labor-intensive and requires careful removal and reinstallation of the wiring harness and all parts.
My backup camera screen is black. Is the camera broken?
Not necessarily. First, check to see if your vehicle is affected by NHTSA recall 19V654000, which causes a black screen due to a software glitch. If the software is up to date, the problem could be the camera itself, a damaged wire, or an issue with the Display Control Unit (DCU). Proper diagnosis is needed before replacing parts.
