The Complete Infiniti G37 Interior Restoration Guide: Bring Your Cabin Back to Life
You slide into the driver’s seat of your G37, and instead of that premium feeling you remember, the dashboard has sticky spots, the leather looks tired, and the trim pieces show years of wear — but here’s the good news: restoring your Infiniti’s interior is completely doable, and this guide will walk you through every step.
TL;DR
Restoring an Infiniti G37 interior costs anywhere from $50 for DIY cleaning supplies to over $2,000 for professional dashboard replacement. The most common issues include sticky or cracking dashes (particularly on 2008-2009 models), worn leather seating surfaces, and damaged trim pieces. Many owners successfully restore their interiors through careful cleaning, professional leather dyeing, dashboard wrapping, or complete interior color changes. With the right approach and products, you can bring your G37’s cabin back to near-showroom condition.
Key Takeaways
- 2008-2009 G37 models are notorious for dashboard melting and cracking — a known quality defect that Infiniti has generally refused to cover
- Most G37 seats are partial leather — only the seating surfaces where your body touches are real leather; the sides and backs are vinyl
- Leather conditioners won’t penetrate the protective coating on G37 leather seats — they’ll just sit on top and may leave a film
- Professional dyeing can completely transform your interior color for around $500-800 in materials
- A full interior restoration typically involves removing the dashboard, door panels, and center console for proper prep work
- Small trim clips and parts are surprisingly affordable, with many costing under $5 from Infiniti parts dealers
Understanding Your G37 Interior Materials
Before you start any restoration project, it helps to know what you’re working with. The G37 interior uses a mix of materials:
Real Leather vs. Vinyl: Here’s a quick trick — press your thumb into the seat surface. If it creases like skin, it’s real leather. If it just sinks in without creasing, it’s vinyl . Most G37 seats use real leather only on the seating surfaces (where your back and legs touch). The side bolsters, seat backs, and rear seats are often vinyl .
Coated Surfaces: This is important — your G37’s leather has a protective clear coating from the factory. That means traditional leather conditioners won’t actually soak in and condition the leather . Many owners have found that products like 303 Aerospace Protectant work better because they protect the coating rather than trying to penetrate it .
Dashboard Material: The dash is not real leather — it’s a vinyl or coated material. On 2008-2009 models, this material is known to break down, becoming sticky or developing cracks . One owner’s dash replacement quote came in at over $2,300 .
Common G37 Interior Problems and Solutions
Sticky or Cracked Dashboard (2008-2009 Models)
If you own a 2008 or 2009 G37, you might have experienced this. The dashboard material on these models can break down over time, becoming sticky to the touch or developing cracks .
Solution Options:
- Dashboard Replacement: Cost around $2,300+ at the dealership. Infiniti has generally refused to cover this under warranty, even for low-mileage garage-kept cars . Some dealers have offered discounts, but it’s still expensive.
- Dashboard Wrapping: Some owners have successfully wrapped their dash in vinyl or leather-look material. One owner used “leather vinyl wrap” from eBay and reported decent results over flat surfaces, though complex curves and edges are challenging .
- Full Restoration: One dedicated owner completely removed their dashboard, repaired cracks with filler, sanded everything smooth, and repainted the entire dash. This approach requires significant skill but delivers professional results .
Worn or Damaged Leather Seats
Leather wear is common on G37s, especially on the driver’s side bolster where you slide in and out .
Solution Options:
- Professional Leather Dyeing: Leather World Technologies offers custom dye kits that match factory colors. One owner used their kit for a complete color change from tan to black, and the results were dramatic .
- Leather Repair: For tears or damage, professional repair specialists can patch and color-match the area. One owner had a tear on their rear seat back repaired by a dealer-sent specialist with good results .
- Proper Cleaning Products: Use Lexol Cleaner and 303 Aerospace Protectant for maintenance. Avoid over-conditioning products that can’t penetrate the factory coating .
Peeling Door Trim and Speaker Grilles
Door trim peeling and damaged speaker grilles are common on higher-mileage G37s .
Solution Options:
- Replace Door Panel: The left door trim in the G37 is prone to peeling. Replacement door panels can be sourced through Infiniti parts dealers.
- Speaker Grille Replacement: A damaged right door speaker grille can be replaced individually, which is more affordable than replacing the entire door panel .
Scratched or Damaged Trim Pieces
Solution Options:
- Replace Trim Clips: Interior trim clips are inexpensive — many cost between $2.64 and $3.22 from Infiniti parts . For example, the body A-pillar trim panel clip is $2.64 .
- Color Change: One owner completely changed their interior color from tan to black by removing all trim pieces, sanding them, and repainting with high-quality interior paint. This approach required removing the dashboard, door panels, and center console — a major project but with stunning results .

Frequently Asked Questions
How do I fix a sticky dashboard on my G37?
Sticky dashboards are common on 2008-2009 G37s. Options include dashboard replacement (expensive), professional or DIY vinyl wrapping, or full restoration with sanding and repainting . Some owners have also reported success with leather-vinyl wrap over flat surfaces .
Is the G37 interior real leather?
Only partially. The seating surfaces where your body touches (center sections of front seats) are real leather. The side bolsters, seat backs, and rear seats are typically vinyl or synthetic material . You can test by pressing your thumb into the surface — real leather will crease, while vinyl just sinks in .
Why won’t leather conditioner soak into my G37 seats?
The G37’s leather has a factory-applied protective coating. Leather conditioner can’t penetrate this coating, so it just sits on top and may leave a film. Products like 303 Aerospace Protectant are more effective because they protect the coating itself .
Can I change the color of my G37 interior?
Yes! One owner successfully changed their interior from tan to black using a dye kit from Leather World Technologies for the leather and automotive paint for the trim pieces. This involved removing the dashboard, door panels, and seats . Another owner documented a complete two-tone color change with professional results .
How much does a dashboard replacement cost for a G37?
Dealership quotes for dashboard replacement have been reported at over $2,300. Infiniti has generally refused to cover this as a warranty claim, even for relatively low-mileage garage-kept cars . Some dealerships have offered discounts, but it’s still expensive.
What cleaning products are safe for G37 interiors?
The G37 owner manual recommends using a mild soap solution and water for most surfaces . The community strongly recommends 303 Aerospace Protectant for vinyl and coated leather, and Lexol for cleaning leather surfaces . Avoid benzine, thinner, or ammonia-based cleaners .
How do I remove the rear seat bottom in a G37?
