2020-2022 Genesis G90 Decklid: Power Trunk, Light Bar, and Camera Guide

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While the 2020-2022 Genesis G90 has several recalls, none directly pertain to the structure or primary function of the decklid itself. However, owners should be aware of related issues and general problems reported for this vehicle generation.

• Recalls: The G90 has active recalls for issues like fuel pumps, seat belt pretensioners, and oil leaks on certain engine models. There are no recalls for the decklid panel, power trunk mechanism, or integrated lighting.
• Power Trunk Malfunctions: Some owners of the first-generation G90 (which includes these model years) have reported intermittent issues with the power trunk failing to open, close, or latch properly. This can be caused by a misaligned lid, a failing power latch (cinch motor), or a problem with the main drive unit. The owner's manual notes that operating the power tailgate more than 5-10 times continuously can temporarily disable the motor to prevent overheating.
• No Specific TSBs: Searches for Technical Service Bulletins (TSBs) related specifically to the decklid, light bar, or power trunk mechanism for the 2020-2022 models did not yield any specific results. TSBs were found for other areas like seat noise and transmission sensors.

Symptoms of a Failing or Damaged Decklid

Problems with the G90 decklid can be mechanical, electrical, or cosmetic.

1. Power Trunk Failure: The most common issue is a malfunction in the power open/close system. This can manifest as the trunk not responding to the key fob or interior button, opening or closing only partially, or making grinding noises.
2. Center Light Bar Issues: The full-width LED light bar may fail partially or completely. Look for dead spots (individual LEDs not illuminating), flickering, or condensation inside the lens, which indicates a failed seal.
3. Rear-View Camera Problems: A blank or flickering screen when the car is in reverse points to a problem with the camera or its wiring. A foggy or blurry image may just be a dirty lens, but could also indicate moisture inside the camera housing.
4. Water Leaks: Water stains, moldy smells, or dampness in the trunk are signs of a bad decklid seal or a poorly repaired panel.
5. Poor Alignment: Uneven gaps between the decklid and the quarter panels, or a lid that sits too high or low, indicates a past collision or improper installation. This can lead to wind noise and water leaks.
6. Latch Failure: The trunk may fail to latch securely or, conversely, may not release at all. You might hear the latch actuator trying to work, but the mechanism fails to engage or disengage.

Buying a Used 2020-2022 G90 Decklid: What to Check

Due to the high cost of new components, a used OEM decklid is an excellent option, but careful inspection is crucial. The 2020 facelift makes this part specific to 2020-2022 models.

Inspection Checklist:

• Verify Compatibility: Ensure the decklid is from a 2020, 2021, or 2022 G90. Lids from 2017-2019 models will not fit or match cosmetically.
• Inspect the Light Bar: This is a very expensive component. Check the lens for cracks, deep scratches, and any signs of hazing or moisture inside. If possible, ask the seller to test it. A used center light bar alone can be found with missing clips or other minor damage.
• Check the Camera: Inspect the camera lens for scratches or cloudiness. Verify the mounting points are intact.
• Look for Hidden Damage: Run your hand along all surfaces to feel for waves that indicate body filler. Check the underside for any signs of non-factory welds, mismatched paint, or structural repairs.
• Verify the Paint Code: If you hope to avoid repainting, you must find a lid with the exact same paint code as your vehicle. Even then, expect minor variations due to sun exposure. Be prepared to have it professionally painted and blended.
• Check the Wiring Harness: Inspect the entire wiring harness that runs into the decklid. Look for cut wires, damaged connectors, or signs of previous repair, which can cause electrical gremlins later.
• Confirm Included Parts: A complete used assembly should include the outer panel, inner structure, center light bar, camera, and wiring. Clarify with the seller if emblems, the power latch, or power struts are included.

Cost of Replacement

The integrated electronics make this a particularly expensive part to replace. Prices are estimates and can vary by location and supplier.

Installation Overview

• Difficulty: 4 out of 5. This is a challenging installation for a DIYer.
• Time: 2-4 hours, not including painting.
• DIY Feasible: Not recommended for beginners. The decklid is heavy and requires a helper to lift and align. The main challenges are safely transferring the expensive electronic components and aligning the panel perfectly.
• Calibration: After replacement, the rear-view camera may require calibration using a scan tool to ensure the on-screen guidelines are accurate.

The basic steps involve removing the trunk liner, disconnecting the battery, unplugging all electrical connectors for the lights, camera, and latch, supporting the lid, unbolting the hinge struts and hinge bolts, and then carefully lifting the old lid off with a helper. The process is reversed for installation, which requires careful alignment before tightening the bolts.
