2020-2025 Genesis G90 & GV60 Steering Wheel Controls: Diagnosing Switch Failures and Software Glitches

Symptoms of Failure

Diagnosing issues with the combination switch in a Genesis G90 or GV60 can be tricky, as symptoms of a true hardware failure can be similar to software glitches known to affect these vehicles. It's important to distinguish between the two.

Symptoms of a Physically Failing Switch

A physical defect or wear inside the combination switch assembly typically results in consistent, repeatable problems. These symptoms will likely not be fixed by restarting the car.

• Turn Signal Problems: The turn signals may not activate, may not cancel after a turn, or the indicator on the dash might stay on. This is often one of the first signs of failure because the turn signal contacts are used most frequently.
• Headlight and High Beam Issues: You might experience headlights that flicker, fail to turn on, or get stuck on one setting. An inability to switch between high and low beams is also a common symptom.
• Windshield Wiper Malfunctions: The wipers may not turn on, might only work on a single speed, or could operate intermittently without being switched on.
• Loose or Sticking Stalks: The control stalks may feel loose, wobbly, or make grinding sounds. They might not return to their center position smoothly after use.

Symptoms Related to Known Software Issues

Unlike a physical failure, software-related problems on these specific models often appear intermittently and can be temporarily resolved by turning the vehicle off and on again.

• Intermittent Steering Wheel Controls (GV60): Owners of the 2023-2024 Genesis GV60 have reported that all steering wheel buttons (cruise control, audio volume, lane monitoring) can suddenly stop working. This is a known issue addressed by a software update.
• Blank Instrument Panel on Startup (G90 & GV60): A more serious issue, covered by a recall, can cause the entire instrument panel display to remain blank upon starting the vehicle. This prevents you from seeing the speedometer, warning lights, and other critical information. This is also a software error, not a fault with the combination switch itself.

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

As of early 2026, there are no widespread reports, recalls, or TSBs for the physical failure of the combination switch on the 2020-2025 G90 or 2023-2025 GV60. However, several significant software campaigns exist that mimic switch failure symptoms.

Genesis Service Campaign T35G (GV60)

NHTSA ID: 23-01-087G
Vehicles: Certain 2023-2024 Genesis GV60 models.
Problem: The Steering Wheel Remote Control (SWRC) switch may not work intermittently. Owners report a temporary loss of all steering wheel button functions. 🎬 See how steering wheel control switches are typically removed. Solution: Dealers perform a software update for the SWRC system to improve switch operation. This is not a parts replacement.

Genesis Recall 027G (G90 & GV60)

NHTSA Campaign Number: 25V474000
Vehicles: 2023-2025 Genesis G90 and 2023-2025 Genesis GV60. Problem: Due to a software error, the instrument panel cluster display may be temporarily blank upon vehicle start-up. This is a safety hazard as it hides the speedometer and other essential information. Solution: Dealers will update the instrument panel cluster software at no charge. Genesis also plans to offer an Over-The-Air (OTA) update for eligible vehicles.

Buying a Used Combination Switch: What to Look For

If you have confirmed that your combination switch has a physical fault (e.g., a broken stalk or consistent, non-software-related failure), buying a used OEM unit is a cost-effective solution, especially given the high price of a new part. Here’s what to check:

• Verify the Part Number: The most important step. You must match the OEM part number exactly. The primary number for these vehicles is 934B2-CU580-4X. Using an incompatible switch can cause features to malfunction.
• Physical Inspection: Carefully examine photos or the part in person. Check for any cracks in the plastic housing, damage to the wiring connectors, or bent pins. Ensure the stalks move freely without binding and have a solid, positive click-feel.
• Check the Clockspring Ribbon: Since this is an integrated unit, inspect the clockspring ribbon cable if it's visible. Look for any creases, tears, or damage that could cause airbag or button failures down the line.
• Understand the Limitations: Remember, a used combination switch is a hardware fix. It will not solve the software issues described in the TSBs and recalls. Your vehicle will still need the appropriate software updates from a Genesis dealer to fix those problems.
• Why Used OEM is a Good Choice: For a complex electronic part like this, a used original equipment (OEM) part is often more reliable than a new, unproven aftermarket version. You get the same quality and fitment as the original part at a fraction of the cost.

Cost of Replacement

Replacing the combination switch assembly is an expensive repair if you buy a new part from the dealer. A used OEM part offers significant savings.

Replacement Overview (DIY Difficulty: 3/5)

Replacing the combination switch requires removing the steering wheel and handling the airbag module, which carries risk if not done correctly. This is a moderately difficult job for an experienced DIYer.

General Steps:

1. Disconnect the Battery: Disconnect the negative terminal of the 12V battery and wait 15 minutes.
2. Remove the Airbag: Release the airbag module from the steering wheel. This is typically done by inserting a tool into small access holes on the sides or bottom of the steering wheel to release spring clips.
3. Disconnect and Remove Steering Wheel: Carefully disconnect the airbag and steering wheel button connectors. Use a large socket to remove the center nut holding the steering wheel, and then pull the wheel straight off the column.

4. Remove Steering Column Covers: Unscrew and unclip the plastic covers from around the steering column to access the switch assembly.
5. Replace the Switch Assembly: Disconnect the electrical connectors from the old switch. Unbolt or unclip the old assembly and install the new one, ensuring the clockspring is centered.
🎬 Watch this guide on how to properly replace a clockspring.
6. Reassemble: Follow the steps in reverse. Torque the steering wheel nut to the manufacturer's specification. Reconnect the battery and test all functions (turn signals, lights, wipers, horn, and all steering wheel buttons).
