2017-2020 Maserati Levante Trunk Floor: Damage, Water Leaks, and Replacement Guide
This guide covers the common issues, inspection points for used parts, and related water leak problems affecting the trunk floor of the 2017-2020 Maserati Levante.
- The most common issues are physical damage from accidents or overloading, not spontaneous failure.
- Water leaks are a significant related problem in the Levante trunk; check for dampness and musty smells before buying a used part and fix the leak source.
- Replacement is extremely simple and can be done by any DIYer in under 30 minutes with no special tools.
- The main floor panel is Maserati part number 670065628. Aftermarket versions are not available, making a clean, used OEM part the best value.
Symptoms of a Damaged Trunk Floor Support
Unlike electronic or mechanical parts, the trunk floor support doesn't typically 'fail' on its own. Instead, problems are almost always caused by physical damage or related issues like water leaks. Here’s what to look for:
- Sagging or Uneven Trunk Floor: The most obvious symptom is a trunk floor that is no longer flat. This is often caused by overloading the trunk with weight beyond its design limits, leading to bending or cracking of the support panel.
- Visible Cracks or Breaks: Physical inspection may reveal cracks, splits, or breaks in the panel, especially after a rear-end collision or if a very heavy, sharp object was dropped in the trunk.
- Rattling or Creaking Noises: A damaged or loose trunk floor support can shift while driving, creating rattling or creaking sounds from the rear of the vehicle. This indicates that mounting points may be broken or the panel itself is fractured.
- Water Damage and Mold: A significant issue for Levante owners is water leaking into the trunk. If you notice damp carpets, a musty smell, or visible mold, the trunk floor support underneath may be compromised. Water can cause the composite material to degrade and can lead to corrosion on the vehicle's body where the support mounts.
Warning: Water leaks in the trunk are a known issue and can be caused by failing taillight seals, window seals, or clogged sunroof drains. If you find water, it is critical to identify and fix the source of the leak, not just replace the damaged trunk components.
Buying a Used 2017-2020 Levante Trunk Floor Support
Since this is a structural part, buying a used OEM component is a great way to save money, as aftermarket versions are generally not available. A used, undamaged OEM panel is identical to a new one. Here’s what to check before you buy:
- Inspect for Cracks and Stress Marks: Carefully examine the entire panel, especially around the edges and mounting points. Look for any hairline cracks or white stress marks in the plastic/composite material. Bend the panel slightly to see if any hidden cracks appear.
- Check for Flatness: Place the support on a flat surface to ensure it is not warped or sagging. Any deviation means it has been compromised and will not fit correctly.
- Look for Signs of Water Damage: Check for water stains, discoloration, or a lingering musty odor. Pay close attention to any areas that would be near the vehicle body, looking for rust transfer. Avoid any part with signs of prolonged water exposure.
- Verify All Mounting Points are Intact: Ensure that all bolt holes, clips, and integrated fastening points are present and undamaged. A broken mounting point is a common result of collision damage or improper removal and will prevent a secure installation.
- Confirm the Part Number: The main floor panel is often listed as the 'Lower Boot Compartment Panel'. The OEM part number is 670065628. Other related supports may have different numbers, so match the part you are replacing with photos and part numbers from the seller.
Pro Tip: When buying online, ask the seller for high-resolution photos of both the top and bottom surfaces, as well as close-ups of all mounting tabs. This will help you spot potential damage that isn't obvious in a wide shot.
Known Issues, Recalls, and TSBs
There are no specific recalls or Technical Service Bulletins (TSBs) from Maserati or the NHTSA for the trunk floor support itself. This is expected for a simple structural component.
However, the 2017 model year, in particular, was subject to several recalls for issues like engine software bugs that could cause stalling and problems with the seat wiring harnesses. While unrelated to the trunk floor, this highlights the importance of checking the overall vehicle history. The most relevant known issue for this part is the potential for water ingress into the trunk area from various seals.

Frequently Asked Questions (FAQ)
Can I still drive with a broken trunk floor support?
Yes. A broken trunk floor support does not affect the safety or drivability of the vehicle. However, you will lose the ability to carry heavy items in the trunk, and a broken panel could rattle or allow items to fall into the spare tire well.
Why is my trunk carpet wet? Is it related to the floor support?
While the floor support itself doesn't cause leaks, it can be damaged by them. Water leaks in the Levante trunk are a common complaint, often stemming from bad seals around the taillights, rear window, or clogged sunroof drains. If your carpet is wet, you must find and fix the leak source to prevent mold, corrosion, and damage to a new floor support panel.
Is the trunk floor support the same as the trunk mat?
No. The trunk floor support is the rigid, structural panel that forms the base of the trunk. The trunk mat is the flexible, carpeted or rubber liner that sits on top of the support panel for aesthetic and protective purposes.
What is the difference between OEM part 670065628 and 670034584?
Part number 670065628 refers to the main 'Lower Boot Compartment Panel', which is the primary floor. Part number 670034584 is also a valid part for the trunk area, likely a smaller bracket or support piece. It is essential to visually match your old part to the replacement or confirm with a dealer using your VIN to ensure you are ordering the correct component for your needs.
