2008-2019 Maserati GranTurismo Dash Trim: A Guide to Sticky Buttons & 2018+ Updates
This definitive guide covers the infamous sticky interior coating failure, replacement options, and the critical 2018 infotainment update you must know about before buying a used panel.
- The primary failure is a chemical breakdown of the soft-touch coating, causing a sticky surface; it is not dirt and requires stripping to fix.
- A critical compatibility trap exists: 2008-2017 panels are different from 2018-2019 panels due to an infotainment system update. They are not interchangeable.
- When buying a used panel, the most important check is the condition of the fragile mounting tabs on the back; broken tabs will cause rattles and poor fit.
- Professional refinishing offers a permanent solution, as a new OEM part will eventually suffer from the same sticky coating failure.
Primary Failure: The "Sticky Interior" Plague
The most common and well-documented issue with the 2008-2019 Maserati GranTurismo's interior is the degradation of the soft-touch coating used on the instrument panel trim and other plastic components. This is not caused by dirt or lack of cleaning; it is a chemical breakdown of the rubberized coating itself. The primary culprits are prolonged exposure to heat and UV rays, which cause the material to revert to a sticky, gummy state over time. This issue affects the entire production run, though models in warmer climates may experience it sooner. Even later 2018-2019 models, while featuring fewer physical buttons, still use materials susceptible to this problem.
Symptoms of a Failing Instrument Panel Trim Panel
- Sticky or Gummy Surface: The trim feels tacky or sticky to the touch, like old tape.
- Black Residue: Touching the panel leaves a black, oily residue on your fingers or cleaning cloths.
- Unpleasant Appearance: The surface collects dust, fingerprints, and lint, making it look perpetually dirty.
- Peeling or Flaking Finish: In advanced stages, the coating may begin to peel or flake away from the underlying plastic.
- Cracked Mounting Points: The plastic tabs and screw bosses on the back of the panel are fragile and can crack or break during removal, leading to a poor fit and rattles.
Buying a Used GranTurismo Instrument Panel Trim: What to Check
Due to the extremely high cost of new OEM parts, a quality used panel is often the best choice. However, careful inspection is critical to avoid buying a part that has the same issues or won't fit your vehicle.
Compatibility Warning: The 2018 model year introduced a major interior update. Pre-2018 models use a smaller screen with physical button arrays, while 2018 and 2019 models feature a larger 8.4-inch MTC+ touchscreen with integrated controls. The shape and cutouts of the instrument panel trim are completely different. Ensure the panel you are buying matches your vehicle's year and infotainment system.
Physical Inspection Checklist
- Verify the Year and System: First, confirm the panel is for a pre-2018 or 2018+ vehicle. A 2017 panel will not fit a 2018 car, and vice-versa.
- Check for Stickiness: Ask the seller directly about the surface condition. Look for shiny, uneven, or hazy spots in photos, which indicate a degrading or improperly cleaned finish.
- Inspect All Mounting Tabs: This is critical. Ask for clear photos of the back of the panel. Check every screw boss and clip receiver for cracks or evidence of being repaired with epoxy. Broken tabs will prevent the panel from sitting flush and will cause rattles.
- Look for Scratches and Cracks: Inspect the face of the panel for deep scratches or cracks in the plastic, especially around the vent and clock openings.
- Confirm the Finish: GranTurismos were available with different trim finishes (e.g., standard black, carbon fiber, wood grain). Ensure the part you're buying matches your car's interior trim package.
Repair vs. Replacement
If your existing panel is physically intact, you have options besides full replacement.
- DIY Refinishing: Many owners strip the sticky coating themselves using solvents like denatured alcohol or ammonia. This is a very labor-intensive process that requires removing the panel from the car. After stripping, the bare plastic can be left as-is or repainted with a high-quality interior trim paint, such as SEM Trim Black, for a factory look.
- Professional Refinishing Service: For a guaranteed result, companies specialize in restoring these parts. They professionally strip the failed coating and apply a new, more durable finish that is guaranteed not to become sticky again. This is the recommended path for a perfect, long-term solution.
Cost Comparison
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM | $1,500 - $6,500+ | Extremely expensive and may be hard to source. The new part uses the same coating that will eventually fail. |
| Used OEM | $200 - $600 | Varies by condition and seller. A cost-effective option if you can find a non-sticky panel with intact mounting tabs. |
| Professional Refinishing | $300 - $700 | Cost to refinish your existing panel. Provides a permanent fix while retaining the original part. |
| Aftermarket | $500 - $2,500 | Generally available as carbon fiber overlay kits that stick on top of the factory panel, not full replacements. |
| Shop Labor for Installation | $150 - $300 | Typically 1-2 hours of labor for removal and installation. |
Installation Difficulty: 2/5
Replacing the instrument panel trim is feasible for a careful DIYer with the right tools. The difficulty is a 2 out of 5. The main risk is breaking the fragile plastic mounting clips on the panel itself or on surrounding trim pieces.
Estimated Time: 1-2 hours
Tools Required: Plastic trim removal tools, Phillips head screwdriver.
General Steps:
- Disconnect the vehicle's battery to prevent any electrical issues.
- Using plastic trim tools, carefully pry away any adjoining trim pieces, such as side panels or lower console trim.
- Once access is clear, gently pry the main instrument panel trim away from the dashboard. It is held in by clips.
- Pull the panel out just enough to access the electrical connectors on the back for the clock, hazard switch, and any other controls.
- Disconnect the connectors and fully remove the panel.
- Installation is the reverse of removal. Ensure all connectors are securely plugged in before clipping the panel back into place.
Pro Tip: When removing old plastic trim, work slowly and apply even pressure. If a clip feels stuck, try prying from a different angle rather than forcing it, which can cause the brittle plastic to snap.
Recalls and Technical Service Bulletins (TSBs)
While the Maserati GranTurismo has been subject to several safety recalls for issues related to airbags, tie rods, and lighting, there have been no official recalls or TSBs issued for the cosmetic problem of sticky interior trim. This is because it is not considered a safety defect by Maserati or the NHTSA.
Frequently Asked Questions (FAQ)
Can I fix the sticky trim without removing it from the car?
It is not recommended. The solvents required to remove the sticky coating (like alcohol or ammonia) can easily damage the surrounding leather dashboard and other surfaces. For a proper and safe repair, the panel should be removed from the vehicle first.
Will a trim panel from a GranCabrio (Convertible) fit a GranTurismo (Coupe)?
Yes, the dashboard and instrument panel trim are the same for both the Coupe and GranCabrio models of the same model year range (pre-2018 or 2018+).
Can I upgrade my 2017 GranTurismo with the 2018 touchscreen and trim panel?
This is not a simple plug-and-play swap. Upgrading to the 2018+ MTC+ infotainment system involves changing the trim panel, the head unit, wiring harnesses, and potentially other control modules. It would be a complex and expensive custom project.
Why is a professionally refinished part better than a new OEM part?
A new OEM part uses the exact same soft-touch coating that failed on the original. It will eventually become sticky again. A professionally refinished part uses a modern, more durable coating that is specifically designed not to break down, providing a permanent solution.
