2014-2024 INFINITI Q50 Trunk Lid Upper Trim: Fixing Rattles, Broken Clips, and Replacement

Symptoms of a Failing Trunk Lid Upper Trim Panel

Since this is an interior trim piece, failure symptoms are almost always seen or heard, rather than affecting vehicle performance. The most common issues are related to the panel's mounting hardware becoming brittle and breaking.

• Rattling or Buzzing Noises: This is the most frequent complaint from Q50 owners. A rattling or buzzing sound coming from the trunk area, especially when driving over bumps or closing the lid, is a tell-tale sign of a loose panel. This is typically caused by one or more broken plastic mounting clips.
• Sagging or Hanging Panel: You may visually notice the panel hanging down on one side or appearing disconnected from the trunk lid. This indicates that multiple clips have failed or that the panel itself has been damaged.
• Broken Mounting Clips: During an inspection or when removing the panel for another repair (like replacing a license plate bulb), you may find that the plastic clips or the receptacles on the panel itself are cracked and broken. These clips become brittle over time and can easily break upon removal.

Known Issues, TSBs, and Recalls

For a simple interior trim part, widespread issues are rare. However, there are some common experiences and related service bulletins to be aware of.

Brittle Retaining Clips

The most common known issue is the fragility of the plastic clips (Part Number 01553-2DR9A) that hold the panel in place. They are known to break easily, especially on older vehicles or in colder climates. Many owners first discover the problem after removing the panel to access the trunk latch, camera, or lighting, only to find the panel won't reinstall securely due to broken clips.

Spare Tire Fitment Clarification

Some parts databases include a warning that fitment may vary for vehicles with or without a spare tire. This warning is generally not applicable to the upper trunk lid trim panel. The presence of a spare tire affects the trunk floor and side liners, not the panel on the lid itself. You can confidently install this panel regardless of your vehicle's spare tire configuration.

Recalls and Technical Service Bulletins (TSBs)

There are no recalls or TSBs from INFINITI or the NHTSA that directly address the trunk lid upper trim panel. While the Q50 has had recalls for issues like driveshafts, steering, and airbags, this specific trim piece has not been the subject of a safety campaign. A TSB (ITB20-022) was issued for potential rust forming near the combination lamps on the trunk lid for 2016-2017 models, which requires removal of the trunk trim for the repair procedure.

Buying a Used 2014-2024 Q50 Trunk Lid Upper Trim Panel

Because this part's failure is almost always cosmetic or related to its mounting points, a used OEM panel is an excellent, cost-effective option. Aftermarket versions are not common, so a recycled part is often the best choice for guaranteed fitment.

1. Inspect the Mounting Points Above All Else

This is the most critical check. Carefully examine the back of the panel. Look at every single rectangular slot where a plastic clip inserts. Ensure these mounting points are not cracked, stressed, or broken. A panel with even one broken mounting point will not sit flush and will likely rattle. A used panel with all mounting points intact is far superior to a new-looking one with damage here.

2. Check for Physical Damage

Look for cracks, deep scratches, or warping on the panel's visible surface. Pay special attention to the area around the emergency release handle opening, as this can be a stress point. Minor scuffs from cargo are normal, but avoid panels with significant structural damage.

3. Part Number Interchangeability

The primary OEM part numbers for this panel are 84911-4GH1A, 84911-4GA0A, and 84911-4GA1A. These numbers often supersede each other, meaning a newer number replaces an older one. For the 2014-2024 model years, these panels are physically interchangeable. Don't be overly concerned if the part number doesn't match yours exactly, as long as it is from a 2014-2024 Q50 and the mounting points are intact.
