2013-2015 Toyota Avalon Decklid: A Guide to Water Leaks, Compatibility, and Replacement
This guide covers the key details for buying a used 2013-2015 Toyota Avalon trunk lid, including how to deal with common water leaks and verify camera and spoiler options.
- Only decklids from 2013-2015 models are a direct fit; parts from the 2016-2018 refresh have different tail light openings.
- Water leaks in the trunk are a known issue, often caused by bad tail light seals, not the main trunk seal.
- Before buying a used decklid, you must verify if it is for a model with or without a rear-view camera and with or without spoiler holes.
- The decklid is a bare shell. A complete used assembly with camera, latch, and trim is often a better value than buying a new bare panel.
Key Compatibility Checks for 2013-2015 Avalon Decklids
When shopping for a replacement decklid for a 2013-2015 Toyota Avalon, several details are critical for ensuring a direct fit. Paying attention to these factors will prevent you from buying an incompatible part.
1. Model Year Range: 2013-2015 Only
Warning: The 2016 Toyota Avalon received a mid-generation refresh that included changes to the rear-end styling, particularly the tail lights and bumper trim. While some OEM parts catalogs may group the 2013-2018 decklid under a single part number, the tail light assemblies and surrounding trim are different. To ensure a direct, bolt-on replacement without modification, you should only purchase a decklid from a 2013, 2014, or 2015 Avalon.
2. Rear-View Camera Provision
The 2013-2015 Avalon was available with or without a factory rear-view camera. A replacement decklid must match your vehicle's original configuration.
- With Camera: The decklid will have a small, square cutout integrated into the chrome garnish above the license plate area to house the camera. The OEM part number for the bare lid is typically 64401-07150.
- Without Camera: The decklid and its chrome garnish will be solid, with no cutout for a camera.
Always inspect photos of a used decklid to confirm the presence or absence of the camera mount.
3. Factory Spoiler Holes
Some Avalon models came equipped with a factory rear spoiler, while others did not. A used decklid may or may not have mounting holes drilled for a spoiler. If your vehicle has a spoiler you wish to keep, you must find a lid with existing holes or be prepared to drill new ones precisely. Conversely, if your car does not have a spoiler, choosing a lid without holes will provide a cleaner look and prevent potential water entry.
Symptoms of a Damaged or Failing Decklid Assembly
Problems with the decklid assembly can range from cosmetic issues to functional failures that compromise security and weather protection.
Water Leaking Into the Trunk
One of the most common owner-reported issues is water accumulating in the trunk, especially in the spare tire well or side troughs. This can lead to musty odors, mold growth, and damage to the hybrid battery in hybrid models. The cause is often not the main trunk weatherstrip, but rather failing seals elsewhere.
- Tail Light Seals: A common point of failure is the foam or rubber seal behind the tail light assemblies. Over time, these seals can dry out and shrink, allowing water that runs down the channels of the trunk to seep into the car.
- Gaps Under Tail Lights: On some Avalons, a gap can form between the body and the lower edge of the tail light assembly, directing water into the trunk vent. A DIY fix involves removing the tail light and applying a bead of outdoor silicone sealant to close the gap.
- Body Seams/Plugs: Less commonly, water can enter through failing factory body seams under the trim or through missing rubber body plugs located under the rear bumper cover.
Trunk Fails to Latch or Open
A trunk that won't stay closed or cannot be opened is a significant problem. This is typically caused by a failure in the latching system.
- Worn Latch Mechanism: The mechanical latch itself can wear out, preventing it from securely grabbing the striker. You might have to slam the trunk to get it to catch, or it might pop open while driving.
- Failed Lock Actuator: The actuator is a small electric motor that locks and unlocks the latch. If this motor fails, you won't be able to lock the trunk or open it with the key fob or interior release button.
- Broken Release Cable: For vehicles with a manual interior release lever, the cable connecting the lever to the latch can snap, rendering the release inoperable.
Backup Camera Malfunction
If the backup camera image on your infotainment screen is fuzzy, black, or not appearing at all, the camera itself may have failed. The camera is a separate component (OEM part number 86790-07010) and can be replaced independently of the entire decklid assembly.
Buying a Used 2013-2015 Toyota Avalon Decklid
Purchasing a used OEM decklid is often the most cost-effective solution for collision repair or damage. Here’s what to look for to ensure you get a quality part.
What to Physically Inspect
- Check for Hidden Rust: Look beyond the surface. Inspect the inner lip where the weatherstrip sits, the areas behind the chrome garnish, and the bottom edge of the lid, as these are common areas for moisture to collect.
- Look for Signs of Previous Repair: Check for waviness in the reflection, which can indicate body filler (Bondo) from a past repair. Look for mismatched paint texture or overspray on the inside of the lid.
- Verify Straightness: Ensure the panel gaps look even and the lid isn't tweaked or bent from a collision. A bent lid will never seal correctly and may cause water leaks.
- Confirm What's Included: Ask the seller if the price includes the bare decklid shell only, or if it comes with the chrome garnish, camera, latch, and wiring harness. A more complete assembly can save you time and money transferring parts.
Why Used OEM is Often Better Than New Aftermarket
For a large body panel like a decklid, a used original equipment (OEM) part has distinct advantages over a new, non-OEM aftermarket part. Used OEM parts are guaranteed to fit correctly, using the same mounting points and panel gaps as the original. They are also made from the same gauge steel as the factory part. New aftermarket panels can sometimes have fitment issues, requiring extra labor from a body shop to align, and may not include the small brackets and provisions found on the original.
Known Issues, Recalls, and TSBs
While there are several recalls for the 2013-2015 Toyota Avalon, none directly pertain to the decklid, latch, camera, or water leaks. Notable recalls for this generation include potential malfunctions of the Pre-Collision System (PCS) and the airbag electronic control unit (ECU). There are no widely published Technical Service Bulletins (TSBs) from Toyota specifically addressing decklid failures or water intrusion for this model range.
Replacement Overview & Difficulty
- Difficulty Rating: 2 out of 5
- Estimated Time: 1.5 - 2.5 hours
- DIY Feasible: Yes, with a helper.
Replacing the decklid is a straightforward process but requires a second person to help lift the old lid off and position the new one without scratching the car's paint. The basic steps involve removing the inner trunk trim panel, disconnecting the wiring harness for the lights and latch, unbolting the four hinge bolts, and then swapping the lids. Components like the latch, camera, and trim are then transferred to the new shell before it is installed.
Cost Comparison
Prices can vary based on condition, included components, and location. The following are estimates to help you understand the value of a used part.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM (Dealer) | $425 - $510 (Bare Lid) | This is for the unpainted metal shell only. Garnish, camera, and latch are extra. |
| New Aftermarket | $650 - $700+ | Typically a bare, unpainted shell. Quality and fit can vary. |
| Used OEM | $300 - $500 | Often comes in the correct color and may include trim, latch, or camera. |
| Shop Labor for Installation | $150 - $375 | To swap the lid and transfer all components. Does not include painting. |

Frequently Asked Questions (FAQ)
Will a trunk lid from a 2016-2018 Avalon fit my 2014 Avalon?
No, it is not a direct fit. The 2016 model year introduced a styling refresh that changed the shape of the tail lights and rear trim. To avoid compatibility issues, you should only use a decklid from a 2013, 2014, or 2015 model.
My trunk is leaking. Do I need a new decklid?
Not necessarily. The most common sources of water leaks are the seals around the tail lights or gaps that form under the lights, not the decklid itself. Before replacing the entire lid, inspect and reseal the tail light areas first, as this is a much cheaper and simpler fix.
Can I add a factory spoiler to a decklid that didn't come with one?
Yes, this is possible, but it requires careful work. You will need to obtain a template to accurately mark and drill the mounting holes in the correct locations. Drilling incorrectly can lead to improper spoiler fitment and create new entry points for water.
My backup camera is blurry. Do I have to replace the whole trunk lid?
No. The backup camera is a self-contained module (part number 86790-07010) that can be unbolted from the chrome garnish and replaced separately. You do not need to replace the entire decklid for a camera issue.
