2017-2020 Bentley Bentayga Lower Door Trim Molding: Replacement and Buying Guide
A detailed reference for inspecting, replacing, and understanding the lower door trim panels on your first-generation Bentley Bentayga.
- The primary reason for replacement is cosmetic damage; the part has no mechanical function.
- When buying a used panel, the most critical inspection is for broken mounting tabs on the back.
- Used OEM parts are the best option for guaranteeing a perfect match with the vehicle's other trim pieces.
- No specific recalls exist for this part, but be aware of different finishes (chrome vs. black) depending on the vehicle's trim package.
Symptoms of a Failing or Damaged Door Trim Panel
Failure of the lower door trim is almost always a visual issue. Since this part has no mechanical or electronic function, you won't see any warning lights. Instead, look for physical signs of damage.
- Visible Damage: Scratches, scuffs, dents, and cracks are the most common problems, usually resulting from impacts with curbs, road debris, or other minor collisions.
- Peeling or Fading Finish: The finish, whether chrome or black, can peel, bubble, or fade over time due to sun exposure and harsh cleaning chemicals. This is especially noticeable on chrome-plated plastic parts.
- Looseness or Rattling: The panel may become loose if the mounting clips break or the adhesive fails. You might hear a rattling or wind noise from the area while driving.
- Complete Detachment: In severe cases, the entire trim piece can fall off the vehicle, leaving exposed mounting holes or adhesive residue on the door.
Pro Tip: Many Bentayga owners opt for a vinyl wrap 'chrome delete' to change the trim to a gloss black finish. If you are buying a used vehicle, be aware that a wrap could be hiding cosmetic damage on the original trim underneath.
Known Issues, Recalls, and TSBs
As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) issued by Bentley or the NHTSA for the failure of the exterior lower door trim panels on the 2017-2020 Bentayga. Most issues with this part are related to cosmetic damage from use, rather than a manufacturing defect.
However, a recall was issued for some 2017 model year vehicles for improperly tightened seat mechanism and instrument panel joints. While not directly related to the exterior trim, it highlights the importance of proper torque and fitment on these vehicles. Another article notes that while the Bentayga has an aluminum body, corrosion can still occur at seams and edges like door sills, which could potentially affect the mounting area for the trim over time.
Buying a Used Exterior Door Trim Panel
Buying a used OEM (Original Equipment Manufacturer) trim panel is often the most cost-effective way to restore your Bentayga's appearance. Because these are cosmetic parts, a careful inspection is critical to ensure you receive a part that meets your expectations.
Key Inspection Points:
- Inspect All Mounting Tabs: This is the most critical step. Turn the panel over and carefully check every single mounting tab and clip receiver. These plastic pieces are brittle and essential for a secure, flush fit. If even one is broken, the panel may not sit correctly and could rattle or detach over time.
- Check for Cracks and Stress Marks: Look for hairline cracks, especially around the mounting points and edges. Flex the part gently to reveal any hidden stress marks, which appear as white or discolored lines in the plastic.
- Examine the Finish: Hold the panel under a bright light and inspect the surface from multiple angles. Look for deep scratches, pitting from road debris, and any signs of the chrome or black finish peeling or bubbling. Minor surface scuffs may be acceptable and can sometimes be polished out, but peeling or cracked finishes cannot be easily repaired.
- Verify the Part Number and Finish: The Bentayga was available with different trim packages. The standard trim is often chrome, while the 'Blackline' specification features gloss black trim. Ensure the part number (e.g., 36A853072 for the right side door trim) and finish match what is on your vehicle. A used OEM part is the best way to guarantee an exact match to the factory finish.
Warning: Avoid cheap aftermarket trim pieces. They often use inferior materials, and the finish may not perfectly match the color and luster of the other OEM trim on your vehicle, resulting in an inconsistent look.
Cost Comparison
Replacing a damaged door trim panel on a Bentayga can be expensive, especially when buying new from a dealer. A used OEM part offers significant savings.

| New OEM (Dealer) | $850 - $1,100+ |
| New Aftermarket | Not commonly available for this specific part. |
| Used OEM (Recycled) | $200 - $450 |
| Shop Labor Cost | $100 - $200 |
Installation Guide
Replacing a lower door trim panel is generally straightforward but requires patience and care to avoid damaging the paint or the new part. The installation difficulty is rated at 2 out of 5.
Required Tools:
- Plastic trim removal tool kit
- Microfiber towels
- Adhesive remover (if applicable)
- Isopropyl alcohol
- New mounting clips (recommended)
Step-by-Step Replacement:
- Protect the Paint: Place microfiber towels or painter's tape along the edge of the door panel to protect the paint from being scratched by tools.
- Remove the Old Panel: Using a plastic trim removal tool, carefully pry one end of the trim panel away from the door. Work your way along the panel, releasing the clips one by one. Listen for the 'pop' of each clip. Use gentle, steady pressure; do not force it.
- Clean the Surface: Once the old panel is off, clean the mounting surface on the door. If there is any leftover adhesive tape, use an adhesive remover to dissolve it. Finish by wiping the area with isopropyl alcohol to ensure it is free of any oils or residue.
- Install the New Panel: Align the clips on the new trim panel with the corresponding holes in the door. Starting from one end, press firmly until you hear and feel each clip snap into place. Work your way down the panel, ensuring it is flush with the door surface.
- Final Inspection: Run your hand along the entire length of the trim to confirm it is secure and there are no loose spots. Remove the protective towels or tape.
Frequently Asked Questions (FAQ)
Is this the chrome trim or the black trim?
This part can be either, depending on the vehicle's original options. The Bentley Bentayga was offered with standard chrome trim or an optional 'Blackline' package that made the trim gloss black. Always verify the finish of the part you are buying matches your vehicle.
Can I repair my damaged trim instead of replacing it?
Minor scuffs might be polished out. However, for peeling chrome, deep scratches, or cracks, replacement is the only effective solution. DIY repair kits using chrome vinyl or putty exist, but they rarely provide a finish that matches the quality expected on a Bentley.
Do I need to buy new clips for installation?
It is highly recommended. The original plastic clips can become brittle with age and often break during removal. Using new clips ensures the replacement panel fits securely and prevents future rattles.
Will a used OEM trim panel match my car's other trim pieces?
Yes, a used OEM part is manufactured by Bentley to the same specifications as your original trim. As long as it is the correct finish (chrome or black), it will match the color and sheen of the other panels perfectly, which is a significant advantage over aftermarket parts.
