McLaren 720S, 765LT, GT & Senna Steering Wheel: A Guide to Wear, Swaps, and Recalls

Symptoms of Steering Wheel Failure

Unlike many car parts, the steering wheel in these McLaren models rarely suffers from catastrophic mechanical or electronic failure. Instead, the most common issues are related to cosmetic wear and tear from normal use.

Cosmetic Wear on Leather and Alcantara

The most frequent issue owners encounter is the degradation of the steering wheel's surface material, especially on wheels trimmed with Alcantara.

• Matted Alcantara: Alcantara is a synthetic suede-like material prized for its grip. However, oils, dirt, and sweat from the driver's hands can cause the fibers to become matted, flat, and greasy. This results in a slick, shiny appearance and a loss of the soft, grippy texture. This is often mistaken for the material wearing away, but it is usually just impacted dirt.
• Shiny or Worn Leather: On leather-wrapped wheels, high-mileage or frequent use can lead to the leather becoming shiny and smooth, particularly at the 9 and 3 o'clock hand positions. Over time, the finish can wear through, and the leather may develop cracks.
• Faded or Worn Stitching: The colorful stitching can fade from UV exposure or become frayed from contact with rings or rough hands.

Electronic Issues

While not widely reported on these models, electronic failures are a possibility for any modern steering wheel. Symptoms would include:

• Inoperative Buttons: One or more of the steering wheel buttons (for infotainment, vehicle settings, etc.) stop working.
• Horn Failure: The horn does not sound when the center pad is pressed. This could be an issue with the horn itself, the wiring, or the clock spring.
• Intermittent Airbag Light: While often caused by other issues, a fault in the clock spring (the coiled wire assembly behind the steering wheel) can trigger an airbag warning light.

Known Issues, TSBs, and Recalls

Critical Safety Recall for 2019-2021 McLaren GT (NHTSA Recall 22V-103)

There is a significant safety recall that directly involves the steering wheel assembly for the McLaren GT. McLaren determined that the connector between the driver's airbag and the vehicle's occupant restraint controller might not be fully engaged. Even if the connection is poor, the airbag warning light may not illuminate, giving a false sense of security. In the event of a crash, a poorly connected airbag may not deploy, increasing the risk of serious injury.

Buying a Used McLaren Steering Wheel

A used OEM steering wheel is a great option, but careful inspection is key. These wheels are often sold as a 'core' only, which is a critical detail to understand.

What to Inspect Before You Buy

• Verify Compatibility: While the core wheel is shared between the 720S, 765LT, GT, and Senna, the trim materials (leather, Alcantara, carbon fiber) and stitching colors vary. Ensure the wheel you're buying matches your vehicle's interior or your desired aesthetic. The provided OEM part numbers are 14NB309CP and 22NA991GP.
• Inspect the Material Condition: For Alcantara wheels, look for heavy matting, permanent stains, or areas worn completely smooth. 🎬 Watch: How to deep clean and restore matted Alcantara For leather wheels, check for deep scratches, cracks, or excessive shininess that indicates heavy wear. For carbon fiber sections, inspect for deep scratches, chips in the clear coat, or yellowing.
• Check the Structure: The steering wheel should be perfectly round and structurally sound. A wheel from a crashed vehicle could be bent or have hidden damage. Ask the seller about the source vehicle if possible.
• Confirm What's Included: This is the most important step. A 'steering wheel core' is just the metal and foam rim. You MUST confirm if the sale includes the button switch packs, the rear plastic trim/housing, and the shift paddles. Most used listings do NOT include these parts or the airbag.

Replacement Information

Replacing the steering wheel is a moderately difficult job that a skilled DIY mechanic can perform. However, it requires extreme care when handling the airbag system.

• Difficulty Rating: 3 out of 5
• Estimated Time: 1.5 - 2.5 hours
• DIY Feasible: Yes, for experienced individuals.

General Replacement Steps

Based on tutorials for these models, the process is as follows:

1. Disconnect the Battery: This is a mandatory safety step to deactivate the airbag system. Wait at least 15-30 minutes for any residual charge to dissipate.
2. Release the Airbag: There are small holes or indentations on the back or bottom of the steering wheel. Insert a thin tool (like a T25 screwdriver or an Allen key) into these holes to press on release springs, which will pop the airbag module forward.
3. Disconnect Wiring: Carefully disconnect the airbag connectors (usually yellow and orange) and the main wiring harness for the steering wheel controls.
4. Remove the Center Bolt: Use a large Torx bit (a T-55 was noted in one video) to remove the central bolt holding the wheel to the steering column. Mark the wheel's orientation before removal to ensure the new one goes on straight.
5. Transfer Components: With the old wheel on a workbench, carefully unscrew and transfer the button packs, shift paddles, and rear trim housing to the new steering wheel core.
6. Installation: Installation is the reverse of removal. Ensure the steering wheel is aligned correctly, torque the center bolt to spec, reconnect all wiring securely (especially the airbag connectors), and press the airbag module back into place until it clicks. Reconnect the battery and test all functions.
