2022-2025 Lucid Air Trunk Lock: Latch Failures, Alignment Issues, and Replacement Guide

Known Issues and Owner Complaints

While there are no specific NHTSA recalls for the trunk lock assembly on the 2022-2025 Lucid Air, owners on forums report several common issues. These problems often appear to be intermittent and can be related to software glitches, component alignment, or electronic faults rather than simple mechanical wear.

• Failure to Close or Latch Completely: Some owners report that the trunk fails to close completely, which can trigger the car's alarm randomly as the system detects an unsecured entry point. This may be caused by an issue with the weather stripping or a misaligned latch that needs adjustment.
• Intermittent Unresponsiveness: A common complaint involves the trunk becoming unresponsive to open or close commands from the exterior button, interior screen, or mobile app. In some cases, the trunk may attempt to open but then seem to get stuck, sometimes requiring multiple attempts before it releases.
• Software and Power Time-Outs: Some electronic issues appear to be by design, though they can be confusing. For example, if the trunk is left open for an extended period (around 10 minutes), the control systems may power down to conserve energy, requiring a manual close. In other instances, a loss of cellular or Wi-Fi service can prevent the mobile app from closing the trunk.
• Phantom Openings: A few owners have reported returning to their parked vehicle to find the trunk (and sometimes the frunk) wide open, without any command having been given.

Symptoms of a Failing Trunk Lock Assembly

Diagnosing a faulty trunk latch on a Lucid Air can be complex due to the integration of mechanical parts, electronics, and software. Here are the most common symptoms to watch for.

1. Trunk Fails to Close or Latch Securely

You may close the trunk, but it doesn't fully engage the lock. The power-cinch feature may not activate, leaving a gap. This will almost always trigger a "Trunk Open" or "Door Ajar" warning on the instrument cluster and in the mobile app. This can be caused by a jammed latch mechanism or a simple alignment issue with the striker.

2. Clicking or Noises Without Action

When you press the release button, you might hear a clicking sound from the trunk area, but the latch doesn't release. This often points to a problem with the electrical actuator or solenoid within the assembly. The motor may be trying to work but is either too weak or has a broken internal component.

3. Trunk Is Unresponsive

The trunk fails to open or close when using the key fob, mobile app, or interior buttons. This could be a sign of a complete electrical failure in the latch assembly, a blown fuse, or a break in the wiring. In some cases reported by owners, the system becomes unresponsive after being left open for a while or if the car is in an area with no data service for the app to function.

4. Trunk Opens Unexpectedly

In rare cases, a faulty latch or a software glitch could cause the trunk to open on its own, either while parked or, more dangerously, while driving. This is a serious safety concern and indicates an immediate need for inspection.

Buying a Used 2022-2025 Lucid Air Trunk Lock Assembly

Since aftermarket options are not available for this vehicle, your choices are a new part from Lucid or a recycled OEM part. A used OEM assembly is a cost-effective and reliable option, provided you inspect it carefully.

What to Check Before Purchasing:

• Verify the Part Number: The most critical step is to match the part number exactly. Known OEM part numbers are P11-C84030 and P11-C84030-04. A different part number, even if it looks identical, may not be compatible with your vehicle's software.
• Inspect the Electrical Connector: Look closely at the electrical connector pins. They should be straight, clean, and free of any corrosion or signs of water damage. A compromised connector is a major red flag.
• Check the Mechanical Latch: Manually actuate the latch mechanism with a screwdriver to ensure it moves freely without binding or sticking. It should feel smooth and snap into place.
• Examine the Housing: Check the plastic housing for any cracks, stress marks, or broken tabs. This could indicate the part was damaged during removal or came from a vehicle involved in a collision.

Cost of Replacement

The cost to replace a Lucid Air trunk lock assembly can vary significantly based on the source of the part and labor rates.

Replacement Overview & Difficulty

Difficulty Rating: 3 out of 5 (Mechanical replacement is easy; potential software calibration is hard)

The physical process of replacing the trunk lock assembly is relatively straightforward for someone with basic mechanical skills. However, the primary challenge and risk with a modern vehicle like the Lucid Air is the potential need for software calibration after installation.

General Replacement Steps:

1. Open the trunk and remove the interior trim panel on the trunk lid to gain access to the latch assembly.
2. Carefully disconnect the electrical connector from the latch.
3. If present, disconnect the emergency manual release cable.
4. Unbolt the old latch assembly from the trunk lid. There are typically two or three bolts holding it in place.
5. Install the new latch assembly, ensuring it is properly aligned before tightening the bolts.
6. Reconnect the electrical connector and any cables.
7. Test the function using the key fob and interior buttons BEFORE reinstalling the trim panel.
8. Reinstall the interior trim panel.
