2017-2022 Genesis G90 Cruise Control Switch: Diagnosing Failed Buttons and Replacement

Symptoms of a Failing 2017-2022 Genesis G90 Cruise Control Switch

When the cruise control switch begins to fail, it can be frustrating and intermittent at first. Understanding the signs can help you pinpoint the problem before it stops working entirely.

• Cruise Control Will Not Activate: The most obvious symptom is pressing the ON/OFF button and getting no response. The cruise indicator light on the dashboard may not illuminate.
• Intermittent Operation: The switch may work sometimes and not others. This can be due to worn internal contacts. You might find it works only when the steering wheel is in a certain position, which often points to a related part called the clock spring.
• Cruise Control Disengages Randomly: You may be driving with cruise control active, and it suddenly turns off without you touching the brakes or the cancel button.
• Buttons are Unresponsive or Sticky: The physical buttons may feel worn, sticky, or fail to register a press.

Is It the Switch or the Clock Spring?

A very common point of failure in steering wheel electronics is the clock spring (related part number 93400-D2420). The clock spring is a special rotary connector that allows the steering wheel to turn while maintaining electrical contact for all steering wheel functions. A bad clock spring can mimic the symptoms of a bad switch.

Here’s how to tell the difference:

• If ONLY the cruise control buttons on the right side of the wheel are malfunctioning, the switch assembly (96700-D2610-NK5) is the most likely culprit.
• If you are experiencing problems with the cruise control buttons AND the audio/phone buttons on the left side, the horn, or you have an airbag warning light on the dash, the clock spring is the almost certain cause.

Known Issues, Recalls, and TSBs

As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Genesis or the NHTSA that directly address failure of the steering wheel-mounted cruise control switch for the 2017-2022 G90. While several recalls exist for this vehicle concerning the engine and fuel system, the cruise control switch itself has not been subject to a recall campaign.

Buying a Used Genesis G90 Cruise Control Switch

A used OEM switch is an excellent, cost-effective alternative to an expensive new part. Since this is primarily an electronic component with no major moving parts, a unit from a low-mileage vehicle is typically very reliable. Here’s what to look for:

• Verify the Part Number: The most critical step is to match the part number. You need 96700-D2610-NK5. While other switches may look similar, they may have different internal resistance and will not function correctly.
• Check the Trim Code: The 'NK5' at the end of the part number designates the color. For this part, NK5 is Black. Ensure this matches your vehicle's interior trim.
• Standard vs. Smart Cruise Control: This switch is for models with standard cruise control. Models with Smart Cruise Control (adaptive cruise) have an additional button to set the following distance to the car ahead. Make sure the button layout on the used part exactly matches your old one.
• Physical Inspection: Check for worn-off button graphics, deep scratches, or cracks in the plastic housing. Ensure the electrical connector is intact with no bent or corroded pins.
• Seller Reputation: Purchase from a reputable seller with a good return policy in case the part is not fully functional.

Replacement Overview & Difficulty

Replacing the cruise control switch is a moderately difficult job that requires careful handling of the airbag module. The process involves removing the airbag to access the screws that hold the switch in place.

1. Disconnect the Battery: Disconnect the negative terminal of your car's battery and wait 15 minutes.
2. Remove the Airbag Module: There are typically access holes on the sides or back of the steering wheel. Use a small screwdriver or a Torx driver to push on release springs inside, which will unlatch the airbag module.
3. Disconnect the Airbag: Carefully lift the airbag module away. Using a small flathead screwdriver, gently pry up the plastic locking tabs on the airbag connectors and unplug them. Also, unplug the horn connector. Place the airbag module aside in a safe place, with the emblem side facing up.
4. Remove the Switch: With the airbag removed, you will see the screws holding the switch assembly to the steering wheel. Unscrew them, disconnect the switch's wiring harness, and remove the old switch.
5. Installation: Installation is the reverse of removal. Install the new switch, connect its harness, reconnect the airbag and horn, and carefully press the airbag module back into the steering wheel until it clicks into place. 🎬 Watch: How to safely remove the steering wheel airbag Reconnect the battery and test all steering wheel functions.
