2019-2022 Genesis G70 Steering Column Module: A Guide to Failure, Programming, and Replacement

Symptoms of a Failing Steering Column Adjustment Module

When the steering column module begins to fail, the symptoms are typically related to the power adjustment features. You may notice one or more of the following issues:

• Steering wheel is stuck: The most common symptom is the complete inability to adjust the steering wheel's position. The tilt and telescope functions will be unresponsive to the control switch.
• Intermittent operation: The adjustment may work sometimes and not others. This can be frustrating as the issue may not be reproducible on demand for a technician.
• Memory function fails for steering wheel: The memory seat and mirror positions may still work, but the steering wheel will not move to its saved position.
• "Easy Access" feature stops working: If you have this feature enabled, the steering wheel will no longer move up and away when you turn off the car and open the door.
• Audible clicking without movement: You might hear a clicking sound from under the dashboard when you try to adjust the wheel, but no movement occurs. This can indicate the module is trying to send power, but a motor or the module itself has failed.
• Warning lights or messages: In some cases, a warning light related to the steering system may appear on the instrument cluster.
• OBD-II Codes: A professional scan tool may reveal Body (B-prefix) or Communication (U-prefix) trouble codes. Codes like U0134 (Lost Communication With Power Steering Control Module) or U0537 (Invalid Data Received From Column Lock Module) could point to issues with related systems, while module-specific codes may also be present.

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

As of this writing, there are no specific recalls or widespread TSBs from Genesis directly targeting the steering column adjustment module for the 2019-2022 G70. However, it's important to distinguish this part from the main steering system components.

• Steering Rack Recall (20V-447): A very small recall (only two vehicles) was issued for the 2020 G70 concerning the main Rack Mounted Motor Driven Power Steering (R-MDPS) assembly, which could make steering difficult. This is unrelated to the adjustment module but involves the broader steering system.
• Other Recalls: The 2019-2022 G70 has been subject to other recalls, including for a potential fuel pump failure and an oil leak on 3.3L turbo models, but these do not pertain to the steering column adjustment module.

While there are no official bulletins, some owners have reported intermittent issues with steering wheel controls, sometimes traced back to a faulty clock spring, which is a separate part within the steering column.

Programming and Calibration: What You MUST Know

This is the most critical information for anyone replacing this module. A replacement Steering Column Adjustment Module, whether new or used, will likely require professional programming to function correctly with your vehicle.

This programming must be done by a Genesis dealership or a well-equipped independent shop that has access to the Genesis Diagnostic System (GDS) or equivalent high-level scan tools. Do not expect a standard OBD-II code reader or a local mechanic without this specific software to be able to perform the programming. An invoice from a dealer or certified shop stating the programming was attempted is often required for returns if you buy a used module.

Buying a Used Steering Column Adjustment Module

Purchasing a used OEM module can be a cost-effective solution, but it requires careful attention to detail. Here’s what to look for:

• Verify the Part Number: This is the most important step. Match the part number on your original module exactly. The primary OEM part numbers are 95450-G9000 (typically for 2019-2021 models) and 95450-G9090 (for 2021-2022+ models). While they may look identical, internal software or hardware could differ. Do not rely on visual similarity alone.
• Confirm Compatibility: Ensure the module came from a Genesis G70 with the same features as yours, specifically the power tilt/telescope column with the Integrated Memory System (IMS). Modules from cars with manual adjustment columns are not compatible.
• Inspect for Damage: Check the casing for any cracks or signs of heat damage. Ensure all connector pins are straight and free of corrosion. Avoid any units that show signs of water intrusion.
• Consider the Source: Buy from a reputable seller who offers a warranty and a clear return policy. Given the programming requirement, having the option to return the part if a professional determines it's faulty is essential.

Replacement Cost Breakdown

The cost to replace the Steering Column Adjustment Module can vary based on the price of the part and local labor rates.

Note: Labor costs can fluctuate. The replacement involves removing the lower dash panel to access the module, which is typically a 1-2 hour job plus programming time.
