2018-2025 Lexus LS500 & LS500h Fender: A Guide to F-Sport and Standard Variants

Fender Variants: F-Sport vs. Standard vs. Advanced Drive

For the 2018-2025 Lexus LS500 and LS500h, not all fenders are the same. The single most important factor when sourcing a replacement is your vehicle's specific trim level. Installing the wrong fender will result in misaligned parts, incorrect badge fitment, or missing features.

Standard (Base) Model Fender

This is the most common fender type. It has a smooth surface without any specific badging holes other than the side marker light cutout. Part numbers like 53801-50220 (Right) and 53802-50220 (Left) are specifically for models without the F-Sport package and without the Advanced Drive system.

F-Sport Fender

The F-Sport package includes unique exterior trim. While the overall shape of the fender is the same as the standard model, it is manufactured with specific locator holes for the F-Sport side badge. While you could theoretically use a standard fender and drill holes, a used F-Sport fender ensures perfect badge alignment. Used parts listings for these vehicles clearly distinguish between fenders for the sport package and those without.

Advanced Drive Fender

Introduced around the 2022 model year, the Lexus Teammate™ with Advanced Drive is an advanced driver-assistance system. Part descriptions for standard fenders explicitly state they are for models "without advanced drive." This strongly implies that vehicles equipped with this technology may have different sensors or mounting hardware within the fender area, requiring a specific part. If your vehicle has Advanced Drive, you must source a fender specifically for that option.

Symptoms of a Damaged Fender

Fender failure is always the result of physical damage. There are no mechanical or electrical symptoms associated with the fender panel itself. Signs you need a replacement include:

• Visible Dents and Dings: Damage from minor impacts, parking lot incidents, or hail.
• Cracks or Punctures: Severe damage from a collision or large road debris. A cracked aluminum fender is difficult to repair and often requires replacement.
• Scratches and Gouges: Deep scratches that go through the paint and primer can expose the aluminum underneath.
• Poor Panel Gaps: Uneven gaps between the fender, door, hood, and bumper can indicate a previous low-quality repair or bent mounting points from an impact.
• Rust or Corrosion: While aluminum does not rust like steel, it can corrode, causing paint to bubble and flake off, especially if the surface was previously scratched or damaged.

Buying a Used Fender: What to Inspect

A used OEM fender is often the best choice, as it guarantees perfect fitment, unlike some aftermarket parts. However, careful inspection is crucial before buying.

1. Verify the Trim Level: This is the most critical step. Confirm with the seller whether the fender came from a Standard, F-Sport, or Advanced Drive model. Look for photos of the F-Sport badge holes if applicable.
2. Check All Mounting Points: Carefully inspect the top, rear (door jamb), and bottom edges for all mounting tabs and bolt holes. Ensure none are cracked, broken, or elongated from stress. A fender with a broken tab will never align correctly.
3. Look for Hidden Repairs: Examine the front and back of the panel. Look for signs of body filler (Bondo), which may appear as a dull or uneven texture. Check for sanding marks or paint overspray on the back side of the fender, which are clear indicators of a previous repair.
4. Assess the Damage: Don't just rely on photos. Ask the seller for close-ups of any dents or scratches. Minor surface scratches are acceptable since the part will need to be repainted, but deep gouges or dents in complex body lines are difficult to fix properly.
5. Confirm the Side Marker Cutout: Ensure the cutout for the side marker light is present and undamaged.

Known Issues, TSBs, and Recalls

As of mid-2024, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Lexus or the NHTSA related to the front fenders of the 2018-2025 LS500 and LS500h. Recalls for these models typically involve systems like the rearview camera, instrument panel software, or occupant sensors.

Replacement Overview

Replacing the fender on an LS500 is a moderately difficult job that requires patience and care to avoid scratching paint. While feasible for an experienced DIYer, proper alignment can be tricky.

• Difficulty: 3 out of 5
• Tools Needed: Ratchet with extensions, 10mm socket, panel removal tools, Phillips screwdriver.
• General Steps:
  1. Partially or fully remove the front bumper cover to access bolts securing the fender.
  2. Remove the front wheel and the plastic fender liner in the wheel well.
  3. Open the front door to access one or two bolts in the door jamb area.
  4. Remove the bolts along the top of the fender in the engine bay.
  5. Remove any remaining bolts or clips at the bottom connecting to the rocker panel/side skirt.
  6. Carefully detach the fender from the car and disconnect the side marker light.
  7. Installation is the reverse of removal. Loosely install all bolts first to allow for adjustment, then tighten them once the panel gaps with the hood, bumper, and door are even.
