2020-2023 McLaren GT Rear Bumper Center Trim (22AA870GP): Damage and Replacement

Symptoms of a Damaged Rear Bumper Trim

Failure of this trim piece is always due to physical impact. There are no mechanical or electrical functions associated with it. Symptoms are straightforward and purely visual:

• Visible Cracks or Scuffs: The most common sign of failure is cosmetic damage from backing into a curb, steep driveway inclines, or impacts from road debris.
• Missing Piece: In a more severe impact, the trim panel can break off completely, leaving an unfinished-looking gap in the center of the rear bumper.
• Loose Fitment: Broken mounting tabs can cause the panel to be loose, vibrate, or hang off the bumper. This can create noise and risks the part detaching completely while driving.

Known Issues, TSBs, and Recalls for the McLaren GT

While there are no recalls or Technical Service Bulletins (TSBs) specifically for the rear bumper trim, several significant safety recalls have been issued for the 2020-2023 McLaren GT that all owners should be aware of.

• Hood Latch Recall (NHTSA Campaign 24V661000): This is a critical recall affecting 1,012 GTs from 2020-2023. Excessive tension in the manual hood release cable can cause the hood latch to open, potentially allowing the hood to fly up while driving and obstruct the driver's view. The remedy is a replacement of the hood latch assembly with a redesigned part.
• Brake Line Recall (NHTSA Campaign 25V216000): Some 2020-2025 GT and GTS models were recalled for incorrectly routed rear brake lines. This could cause the ABS and stability control systems to activate on the incorrect side, increasing the risk of a crash.
• Fuel Tank Corrosion Recall: An earlier recall was issued for some 2020 GT models concerning a foam pad under the fuel tank that could absorb and trap water. This could lead to fuel tank corrosion, creating a risk of a fuel leak and potential fire.

Buying a Used 2020-2023 McLaren GT Rear Bumper Trim

Given the high cost of new OEM McLaren parts, a used OEM trim piece is an excellent value. However, careful inspection is key.

Physical Inspection

Before buying a used trim panel, inspect it carefully:

• Check All Mounting Points: This is the most critical step. The part attaches with a series of plastic tabs and clips. Ensure every single tab is present and free of stress marks or cracks. A part with broken tabs will not fit securely.
• Look for Cracks: Examine the entire surface, especially around the edges and corners, for any cracks. Minor surface scuffs can be acceptable, but deep cracks compromise the part's integrity.
• Inspect for Previous Repairs: Look for signs of plastic welding, glue, or epoxy on the back side of the panel. A poorly repaired part may fail again or fit incorrectly.

Confirming the Correct Part

The OEM part number for this rear center trim is 22AA870GP. Always verify this number against the part you are buying. While this part is consistent across the 2020-2023 GT models, it is not interchangeable with parts from other McLaren models or the later GTS.

Cost Comparison for McLaren GT Rear Bumper Trim

Sourcing parts for a McLaren can be expensive, which makes a used OEM part a very attractive option.

Replacement Overview

Replacing this trim piece is more involved than a typical mud flap. While it doesn't require highly specialized tools, it demands patience and care to avoid damaging the bumper.

• Difficulty: 3/5
• Estimated Time: 1-2 hours
• Tools Needed: Trim removal tools, socket set, screwdrivers.
• Procedure: Access to the mounting clips may require partial removal of the rear undertray or wheel well liners. The old trim is carefully pried off using plastic trim tools to release the clips without breaking them or scratching the bumper paint. The new part is then aligned and pressed firmly into place until all clips engage.
