2023-2025 Kia Niro Tailgate: Power Liftgate Faults and Manual Latch Guide

Critical: Power vs. Manual Tailgate Compatibility

Always verify which system your vehicle has before ordering a part. The easiest way to tell is by checking for a power liftgate button on your key fob, on the dashboard to the left of the steering wheel, and on the tailgate itself.

Symptoms of Tailgate Failure

Tailgate problems can range from minor annoyances to significant safety issues. Failures are typically mechanical (latch, hinges) or electrical (power liftgate motor, switch, wiring).

Power Liftgate Specific Symptoms

• Slow, Jerky, or Stuttering Motion: The tailgate may struggle to open or close, moving slowly or in a jerky manner. This can point to failing lift struts or a weak motor.
• Grinding or Clicking Noises During Operation: Loud grinding can indicate stripped gears inside the motor assembly, while repeated clicking could be a faulty relay or solenoid.
• Fails to Open or Close with Buttons: The tailgate does not respond to the key fob, dashboard switch, or tailgate button. This could be a blown fuse, a bad switch, or a failed control module.
• Tailgate Opens or Closes Partially: The gate may stop moving partway through its cycle, which could be an obstruction sensor issue, a loss of calibration, or a failing motor.
• Warning Chimes or Dashboard Message: The vehicle may display a "Check Power Liftgate" message or emit warning beeps.
• Burning Smell: A distinct electrical burning smell from the rear of the vehicle during operation is a serious sign of a failing liftgate motor.

General and Manual Tailgate Symptoms

• Tailgate Won't Latch or Stay Closed: The most common and dangerous symptom. This is often due to a failed latch mechanism or a misaligned striker.
• "Tailgate Ajar" Warning Light Stays On: Even when the tailgate is fully closed, the sensor in the latch may fail to register it, leaving a warning on your dash.
• Rattling or Clunking Noises: A loose or worn latch can cause the tailgate to rattle against the striker plate while driving over bumps.
• Handle Feels Loose or Requires Force: The exterior or interior release handle may feel disconnected, or you may have to pull it multiple times to get the latch to release. This can be caused by stretched or disconnected linkage rods inside the tailgate.

Known Issues, Recalls, and TSBs for 2023-2025 Kia Niro

As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) for the tailgate assembly of the 2023-2025 Kia Niro. However, there is a significant safety recall for the model range that owners and buyers should be aware of.

NHTSA Recall 25V-024 (Kia Recall SC332)

This recall affects approximately 80,255 Niro Hybrid, Plug-in Hybrid, and EV models from 2023-2025 equipped with a manual front passenger seat. The issue is that repeated movement of the seat can damage the floor wiring assembly underneath it. This damage can prevent the front passenger airbag and seatbelt pretensioner from deploying in a crash, or potentially cause an unintended side curtain airbag deployment, increasing the risk of injury. The fix involves dealers inspecting, rerouting, and installing protective covers on the wiring harness free of charge. While not related to the tailgate, it is a critical safety check for any vehicle in this year range.

Buying a Used 2023-2025 Kia Niro Tailgate

A used OEM tailgate is often the best value, as it typically comes as a complete assembly with glass, wiring, and other components already installed. A new aftermarket part is often just a bare shell, requiring a time-consuming transfer of all original parts.

Step 1: Verify Compatibility

• Power vs. Manual: As stated, this is non-negotiable. Confirm the donor vehicle had the same liftgate system as yours.
• Part Number Match: If possible, match the part number from your original tailgate to the replacement. The primary part number for a manual tailgate shell is 72800-AT020. The rear glass is 87110-AT020. Power liftgate assemblies will have different numbers.
• Component Check: Verify which components are included. Does it come with the glass, wiper motor, camera, lights, and inner trim panel? A bare shell is worth significantly less than a complete assembly.

Step 2: Physical Inspection Checklist

Before purchasing, inspect the used tailgate thoroughly:

• Check for Dents and Scratches: Minor cosmetic flaws can be fixed, but deep dents may be difficult to repair properly.
• Inspect Panel Gaps and Alignment: Look for uneven gaps around the edges, which could indicate the part is from a vehicle with frame damage.
• Look for Hidden Rust: Check the lower edges and inside the seams where water can collect. Use a small magnet to check for the presence of plastic body filler (Bondo), which is not magnetic and can hide previous damage.
• Examine the Wiring Harness: Inspect all visible wiring and connectors for cuts, fraying, or corrosion. A damaged harness is a major red flag.
• Inspect Attached Components: Check the rear glass for cracks or deep scratches. Ensure the camera lens is clear and unscratched. Test the latch mechanism by hand if possible.
• Check for Water Intrusion: If the inner trim panel is attached, check for any musty smells or water stains that could indicate a leaking seal.

Cost Comparison (2023-2025 Kia Niro Tailgate)

Prices can vary based on condition, included components, and whether the part is for a power or manual system. The following are estimates.

Replacement Overview

• Difficulty: 3/5 (Moderate)
• Estimated Time: 2-4 hours
• DIY Feasible: Yes, with a helper.

Replacing the tailgate is a two-person job due to its weight and bulk. The basic process involves supporting the tailgate, removing the interior trim panels, disconnecting all electrical connectors and the washer fluid hose, unbolting the gas support struts, and finally unbolting the main hinges from the body. Installation is the reverse of removal. After installation, the tailgate must be checked for proper alignment and sealing.
