2023-2026 VinFast VF 8 Lid Gate Moulding: Fitment, Damage, and Replacement

Key Variants: Manual vs. Power Liftgate

Before purchasing any lid gate moulding for a 2023-2026 VinFast VF 8, you must first identify your vehicle's liftgate type. The fitment of the trim panels is different between the two configurations.

• Eco Trim (Manual Liftgate): The base 'Eco' trim level typically comes with a standard manual liftgate. The trim panels for this version are shaped accordingly.
• Plus Trim (Power Liftgate): The upgraded 'Plus' trim level is equipped with a hands-free power liftgate, which often includes a kick sensor under the bumper. The mouldings for this version are designed to accommodate the power-closing mechanisms and potentially different handle or button assemblies.

Symptoms of Damaged Lid Gate Moulding

Failure of a lid gate moulding is almost always due to physical damage or age rather than mechanical breakdown. Here’s what to look for:

• Visible Cracks, Scuffs, or Gouges: This is the most common symptom, usually resulting from a minor collision, backing into an object, or scraping against a stationary object.
• Rattling or Vibrating Noises: If you hear noises from the rear of the vehicle, especially when closing the liftgate or driving over bumps, it often indicates that the moulding's mounting clips have broken. The panel becomes loose and vibrates against the liftgate's metal shell.
• Poor Fit or Gaps: A damaged or improperly installed moulding may not sit flush with the vehicle's body. You might notice uneven gaps between the trim and the liftgate or surrounding body panels.
• Faded or Discolored Finish: Over time, exposure to UV rays and weather can cause the plastic or painted finish to fade, chalk, or become brittle. This is a cosmetic issue but can indicate the part is nearing the end of its life.

Buying a Used Lid Gate Moulding: What to Inspect

Since aftermarket options for VinFast body parts are virtually non-existent, a quality used OEM part is often the best and only choice. Here is a detailed inspection checklist:

1. Confirm the Liftgate Type: This is the most critical step. Double-check that the donor vehicle had the same liftgate (manual or power) as yours. Ask the seller to confirm if you are unsure.
2. Inspect Every Mounting Tab and Clip: Turn the panel over and carefully examine all the mounting points. These plastic tabs are brittle and are the most common point of failure during removal. Even one broken tab can cause a rattle or poor fit. Do not purchase a panel with broken or stressed-looking clips unless you are prepared to attempt a plastic repair.
3. Check for Hidden Cracks: Gently flex the panel in your hands. This can reveal hairline stress cracks that are hard to see when the part is stationary. Pay close attention to the areas around any screw holes or sharp corners.
4. Examine the Finish: Look for deep scratches that have gone through the paint or into the plastic itself. Surface-level scuffs can often be polished out, but deep gouges cannot. For unpainted textured plastic, check for chalky, white discoloration from sun damage.
5. Verify Part Integrity: If the moulding is supposed to house a camera, light, or switch, ensure the mounting points for those components are intact and not damaged.

Known Issues, Recalls, and TSBs

As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from VinFast or the NHTSA that directly concern the lid gate moulding on the 2023-2026 VF 8.

However, early model year VF 8 vehicles have been subject to several significant recalls for other issues, including:

• Blank Multifunction Display: A software error could cause the main display, which shows the speedometer and other critical information, to go blank (NHTSA Recall No. 23V355000).
• Airbag Issues: Multiple recalls have been issued for airbags that may have inactive ignitors or could deploy improperly, increasing injury risk (NHTSA Recalls 24V369000, 24V933000).
• ADAS Software: A recall was issued to correct the Advanced Driver Assistance System (ADAS), which could make unexpected steering inputs (NHTSA Recall No. 25V559000).

These issues do not affect the physical fitment of the lid gate moulding but are important for owners to be aware of regarding the vehicle's overall early production quality.

Cost Comparison

Pricing for VinFast parts can be difficult to source due to the newness of the brand in the North American market. The following are estimates to help guide your decision.

Installation Difficulty and Guide

• Difficulty: 2 out of 5
• Estimated Time: 0.5 - 1.5 hours
• Tools Needed: Plastic trim removal tool kit, socket set (if bolted), clean microfiber cloths.

Replacing a lid gate moulding is generally feasible for a DIYer with patience. The key is to use proper trim removal tools to avoid scratching the paint or breaking the plastic clips.

General Steps:

1. Open the Liftgate: Access the interior panel of the liftgate if necessary to remove any screws or bolts from the inside.
2. Remove Fasteners: Carefully locate and remove any visible screws or bolts holding the moulding in place.
3. Pry Gently: Using a plastic trim tool, start at one edge and gently pry the moulding away from the liftgate. You will hear the clips pop as they release. Work your way slowly around the panel.
4. Disconnect Electronics: If the panel contains any lights, cameras, or switches, carefully disconnect the electrical connectors before fully removing the panel.
5. Clean the Surface: Before installing the new part, clean the mounting surface on the liftgate to ensure a good fit.
6. Install the New Panel: Connect any electrical components, then align the clips on the new panel with the holes in the liftgate. Press firmly and evenly until all clips snap securely into place. Reinstall any screws or bolts.
