2018-2021 Buick Enclave Dash Trim: Avenir Woodgrain Guide & Replacement
This guide covers how to correctly identify, inspect, and replace the three-piece instrument panel trim for the 2018-2021 Buick Enclave, with a focus on trim level compatibility.
- The most critical factor is matching the trim to your vehicle's specific trim level; part number 84345962 is for the top-tier Avenir model with its unique Chestnut woodgrain finish.
- When buying a used panel, the highest priority is to inspect the back for intact mounting clips, as broken clips are the primary cause of rattles and poor fitment.
- Replacement is a simple DIY task that requires only plastic trim removal tools and careful, gentle prying to avoid damaging the dashboard or the clips.
- There are no specific recalls or TSBs for this part; issues like rattles or cosmetic wear are handled as standard repairs.
Symptoms of a Failing Instrument Panel Trim Panel
Since this is a cosmetic part, failure is related to physical appearance and fitment rather than mechanical or electrical function. There are no fault codes associated with this part. The most common reasons for replacement are:
- Cosmetic Damage: This includes deep scratches, scuffs, or gouges from daily use. The clear coat over the woodgrain or silver finish can also begin to peel, delaminate, or become cloudy over time, detracting from the interior's appearance.
- Rattling or Creaking Noises: One of the most common complaints for any dash component is noise. Rattles are often caused by broken or loose mounting clips on the back of the trim pieces. Temperature fluctuations can also cause the plastic to expand and contract, leading to creaking or ticking sounds where the trim meets the main dashboard.
- Broken or Warped Pieces: In rare cases, a piece may be cracked from an impact or warped due to extreme heat or improper removal. This will result in poor fitment, visible gaps, and potential rattles.
Variant Differences: Avenir vs. Other Trims
The single most important factor when purchasing this part is ensuring it matches your Enclave's specific trim level. For the 2018-2021 model years, the Enclave was available in several trims, including Base, Essence, Premium, and the top-of-the-line Avenir.
The OEM part number 84345962 specifically refers to the trim set for the Avenir model. This version features a unique Chestnut and Ebony color scheme with a real woodgrain accent officially described as "Asagi Madaraa." This finish was a signature part of the Avenir package and is not interchangeable with the trim found in lower-level models if you want an exact factory match. Other trims used different finishes, such as textured plastics or different simulated wood patterns.
Warning: Always verify the finish and color of a used trim panel by comparing it to photos of your vehicle's interior. Do not assume a part will match based on the year alone. A part from a Premium or Essence trim will physically fit but will not match the Avenir's unique appearance.
Buying a Used Instrument Panel Trim Panel: What to Check
Buying a used OEM trim panel is an excellent way to restore your interior's appearance for a fraction of the new price. However, a careful inspection is essential.
Physical Inspection Checklist
- Inspect All Mounting Tabs: This is the most critical check. Carefully flip over each of the three pieces and inspect every single mounting tab and clip receiver. They should all be intact and free of stress marks or cracks. Even one broken tab can lead to a poor fit and persistent rattles.
- Check for Finish Delamination: Look at the trim under a bright light and from multiple angles. Pay close attention to the edges and corners of the woodgrain sections. Look for any signs of the clear coat lifting, peeling, or bubbling.
- Look for Deep Scratches: Minor surface scuffs may be acceptable and can sometimes be polished out, but run your fingernail over any visible scratches. If your nail catches, the scratch is deep and will be noticeable once installed.
- Verify Color and Grain: If you are buying online, compare the seller's photos to your own vehicle's trim in good lighting. The Avenir's Chestnut wood has a specific color and grain pattern. Be wary of photos that are dark or out of focus.
- Check for Warping: Lay each piece on a flat surface to ensure it is not bowed or twisted. A warped piece will not sit flush against the dashboard.
Pro Tip: Ask the seller for a photo of the back of the exact parts you will receive. This allows you to verify the condition of the mounting clips before you commit to buying.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from General Motors or the NHTSA related to the physical instrument panel trim pieces for the 2018-2021 Buick Enclave. While some owners of various vehicles report dash rattles, this has not been identified as a widespread, warrantable defect for this specific part. Any issues with the trim are typically considered cosmetic wear or damage.

Installation Guide (Difficulty: 2/5)
Replacing the instrument panel trim is a manageable DIY job for most people and requires minimal tools. The estimated time is 30-60 minutes.
Tools Required:
- Plastic Trim Removal Tool Kit
- Microfiber Towel
General Steps:
- Protect the Dash: Place a microfiber towel below the trim piece you are working on to prevent scratches to the main dashboard.
- Pry Gently: Insert a plastic trim removal tool into the seam between the trim panel and the dashboard. Start at one end and gently pry outwards. You will hear the metal or plastic clips begin to release.
- Work Your Way Along the Panel: Move the tool along the panel, releasing one clip at a time. Do not try to pull the entire piece off at once, as this can break the clips or the panel itself.
- Align the New Panel: Before snapping the new piece in, make sure all the clips on the new panel are aligned with the corresponding holes in the dashboard.
- Press to Secure: Once aligned, firmly press the new trim piece into place. You should hear and feel a distinct click as each clip engages. Start from the center and work your way out to the ends.
Frequently Asked Questions (FAQ)
Can I install a trim panel from a different trim level, like a Premium, on my Avenir?
Physically, the panels will likely fit, as the underlying dashboard structure is the same. However, the color and finish will not match. The Avenir has a unique Chestnut/Ebony interior with a specific woodgrain that is different from the materials used in the Premium, Essence, or Base models.
My dash trim is rattling. Do I need to replace it?
Not necessarily. A rattle is almost always caused by a broken or loose mounting clip. You may be able to remove the panel and fix the rattle by applying felt tape to pressure points or using a high-quality adhesive to repair a broken clip mount. However, if the clip itself is broken, replacement is often the most reliable solution.
Can I wrap my existing trim panel in vinyl?
Yes, using automotive-grade vinyl wrap is a popular and cost-effective way to change the look of your interior trim or cover up scratches. This requires patience and skill to apply without bubbles or creases, but it offers a wide range of custom finishes.
Is this a difficult part to replace myself?
No, this is generally considered an easy DIY project. The key is to use plastic trim removal tools instead of metal screwdrivers to avoid scratching your dashboard, and to apply steady, gentle pressure when prying the old pieces off.
