2023-2024 VinFast VF8 Fender Molding: Damage, Fitment, and Replacement

Symptoms of a Failing or Damaged Fender Molding

Failure of a fender molding is almost always visible. Unlike electronic or mechanical parts, you won't get a warning light on your dashboard. Instead, problems are related to physical damage or poor fitment.

Loose Fitment, Gaps, or Rattling

The molding may begin to pull away from the fender, creating a noticeable gap. This is often caused by broken or weakened plastic mounting clips on the back of the part. You might hear rattling or wind noise from the loose part, especially at highway speeds. A loose molding can vibrate against the body, chafing the paint underneath and leading to potential rust issues over time.

Cracks, Scuffs, and Impact Damage

The most common reason for replacement is physical damage. Impacts from parking lot mishaps, road debris, or minor collisions can cause the plastic to crack, gouge, or break entirely. While small scuffs may be cosmetic, significant cracks compromise the part's integrity and can allow water and dirt to get trapped behind it.

Fading and Discoloration

Over time, exposure to UV rays from the sun can cause the black plastic to fade to a dull gray. This is purely a cosmetic issue but can detract from the vehicle's overall appearance. This is less common on newer vehicles like the 2023-2024 VF8 but can happen with intense sun exposure.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from VinFast or the National Highway Traffic Safety Administration (NHTSA) related to the fender moldings on the 2023-2024 VinFast VF8. The vehicle has been subject to several recalls for other issues, including the airbag system, software for the display screen, and the lane-keeping assist function.

While there are no official campaigns for the moldings, early owners and automotive journalists have reported general concerns about build quality and fit-and-finish on the VF8. These reports suggest that owners should pay close attention to the fit and security of all plastic trim and body components.

Buying a Used Fender Molding: What to Check

For a newer vehicle like the VF8, finding aftermarket body parts can be difficult. A used OEM (Original Equipment Manufacturer) molding is often the best choice, as it guarantees a perfect fit and original material quality. When buying a used part, careful inspection is critical to ensure you get a good one.

Key Inspection Points for a Used Molding:

• Inspect All Mounting Points: This is the most important check. Turn the molding over and carefully examine every single mounting tab and clip location. Look for any that are cracked, stressed (showing white lines in the plastic), or broken off completely. A molding with even one broken tab may not sit flush against the fender.
• Check for Hidden Cracks: Flex the part gently to reveal any hairline cracks that might not be obvious at first glance. Pay special attention to the curved areas and the ends of the molding, which are most susceptible to impact damage.
• Look for Warping: Lay the molding on a flat surface to ensure it is not warped or twisted. A warped part will not follow the contour of the fender and will result in unsightly gaps.
• Verify the Finish: Ensure the texture and color of the plastic match what you expect. While fading is less of an issue on recent models, a part from a vehicle stored outdoors in a harsh climate may look different from one stored in a garage.

Cost Comparison

Pricing for new OEM VinFast parts is not widely available through online catalogs and often requires a direct inquiry with a dealer or service center. Aftermarket options are currently scarce or nonexistent.

Replacement Overview & Difficulty

Difficulty Rating: 1 out of 5 (Easy)

Replacing a fender molding on a VF8 is a straightforward task suitable for a DIYer with basic tools. The entire process should take less than an hour per side.

General Replacement Steps:

1. Clean the Area: Thoroughly wash and dry the wheel well and the area around the molding to prevent dirt from scratching the paint during removal.
2. Remove Fasteners: Look inside the wheel well for any screws or plastic push-pins that secure the fender liner and/or the molding itself. Remove them.
3. Pry the Old Molding Off: Starting from one end, use a plastic trim tool to gently pry the molding away from the fender. You will hear the clips pop as they release. Work your way along the length of the molding until it is completely detached.
4. Clean the Surface: With the old molding removed, thoroughly clean the area on the fender where the new part will sit. Remove any dirt, wax, or adhesive residue.
5. Install the New Molding: Align the clips on the new molding with the corresponding holes in the fender. Starting at one end, press firmly to snap the clips into place. You should feel and hear a solid click as each clip engages.
6. Reinstall Fasteners: Secure any screws or push-pins that you removed earlier.
