2020-2022 Genesis G90 Trunk Sill Plate: Fixing Scratches, Scuffs, and Rattles
Your guide to replacing the G90's rear trunk latch cover trim, including what to inspect on a used part and how to ensure a perfect, rattle-free fit.
- This panel is specific to 2020-2022 Genesis G90 models and is not interchangeable with earlier years.
- When buying a used part, the most critical inspection is of the underside to ensure all mounting clips and tabs are intact.
- Failure is limited to cosmetic damage or rattling; the part has no electrical function and is not subject to any safety recalls.
- Replacement is a very simple DIY task that requires only a plastic pry tool and less than 30 minutes.
Symptoms of a Failing Trunk Trim Panel
Since this panel has no electronic or moving parts, failure is almost always related to physical damage or improper fitment. The symptoms are typically straightforward and easy to spot.
Visible Damage: Scratches, Gouges, and Cracks
The most common issue is cosmetic damage. Dragging heavy or sharp-edged items like luggage, boxes, or tools across the panel can cause deep scratches, gouges, or even cracks in the plastic. While minor scuffs are normal, significant damage can be an eyesore on a luxury vehicle like the G90.
Rattling or Looseness
A rattling or buzzing noise from the trunk area, especially when driving over rough roads, can sometimes be traced to a loose trunk sill plate. 🎬 See how to fix a rattling car hatch This happens when the plastic mounting clips or tabs on the underside of the panel break. This can occur from a sharp impact or from improper removal and reinstallation during a previous repair.
Buying a Used 2020-2022 G90 Trunk Trim Panel
Because aftermarket versions of this specific panel are not manufactured, a used OEM part is the most cost-effective replacement option. When buying a recycled panel, careful inspection is key to getting a part that fits securely and looks great.
1. Verify the Part Number and Fitment
The Genesis G90 received a major facelift for the 2020 model year. Trim pieces are not interchangeable with the older 2017-2019 models. You must source a panel from a 2020, 2021, or 2022 G90.
- Correct Part Number: The OEM part number for this panel is 85771-d2600.
- Vehicle Years: 2020-2022 Genesis G90 only.
2. Inspect the Mounting Points (Most Important!)
Warning: A panel that looks perfect on top is useless if its mounting clips are broken. This is the most critical check to perform.
Flip the panel over and carefully inspect all the mounting tabs and the slots where the clips attach. These are essential for a secure, rattle-free fit. Ensure none of the plastic tabs are cracked, stressed, or snapped off. If you are buying online, insist on clear photos of the underside of the panel.
3. Assess Cosmetic Condition
Examine the top surface for damage. Distinguish between light scuffs and deep gouges. Light surface scratches can often be minimized with a plastic polish or trim restorer, but deep gouges that have removed material are permanent. Check for any chemical discoloration or fading, although this is less common for an interior trunk part.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no recalls, common complaints, or Technical Service Bulletins (TSBs) from Genesis specifically concerning the trunk trim sill plate for the 2020-2022 G90. While several recalls exist for this vehicle, they involve components like the fuel pump and turbocharger oil lines, not cosmetic trim. Any issues with this panel are related to wear and tear or physical damage rather than a manufacturing defect.
Replacement Cost Comparison
Replacing a damaged trunk sill plate is much more affordable when using a recycled OEM part.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM | $200 - $350 | Must be purchased from a Genesis dealership parts department. Guarantees perfect condition. |
| Used OEM | $75 - $175 | Widely available from auto recyclers. Price depends heavily on condition. |
| New Aftermarket | Not Available | Aftermarket manufacturers generally do not produce this type of vehicle-specific cosmetic trim. |
| Shop Labor | $60 - $120 | Replacement takes less than 30 minutes, so most shops will charge their minimum fee (0.5 to 1.0 hour of labor). |
Installation Guide (DIY Difficulty: 1/5)
Replacing this panel is a simple DIY job that requires only basic tools and about 15-20 minutes.
Pro Tip: Use a set of plastic trim removal tools. Using a metal screwdriver will almost certainly scratch or gouge the surrounding plastic panels or painted surfaces.
- Empty the Trunk: Remove any cargo, mats, or the trunk floor panel to give yourself clear access.
- Pry Up the Old Panel: Find a seam at one end of the sill plate. Gently work a plastic pry tool under the edge and lift up. You will hear the clips start to release.
- Work Your Way Across: Continue to pry gently along the length of the panel, moving from one clip to the next until the entire piece is loose.
- Remove the Panel: Once all clips are disengaged, lift the panel out.
- Align the New Panel: Position the new trim panel over the trunk latch, ensuring each of the mounting clips on its underside lines up with the corresponding holes in the vehicle's body.
- Snap It Into Place: Starting at one end, press down firmly on the panel. You should hear and feel a distinct "snap" as each clip engages. Continue pressing down across the entire panel until it is fully seated and secure.
- Final Check: Tug gently on the panel to ensure it is locked in place and does not move or rattle. Reinstall the trunk floor and any mats.
Frequently Asked Questions (FAQ)
What is this part officially called?
Its official Genesis part name is the "Rear Trunk Sill Plate Latch Cover Trim Panel". It is also commonly referred to as a trunk scuff plate or sill trim.
Can I just fix my scratched panel instead of replacing it?
For very light scuffs, you may have some success with a high-quality plastic trim restorer or polishing compound. However, for deep scratches or cracks, replacement is the only way to restore the original appearance.
🎬 Watch: How to easily remove scratches from interior trimWill a trunk sill plate from a Genesis G80 fit my G90?
No. Even within the Genesis brand, body and trim parts are specific to each model and generation. You must use a panel specifically from a 2020-2022 G90 for a correct fit.
My new used panel rattles. What did I do wrong?
If the panel rattles after installation, it's almost certainly because one or more of the mounting clips are not fully engaged or were broken on the used part. Remove the panel and inspect all the clips again. If a clip on the panel is broken, the panel will need to be replaced. If a clip was just not seated, reinstalling it carefully should solve the problem.
