2021-2024 Genesis GV80 Steering Column Module: Failures, Programming, and Replacement

Known Issues, Recalls, and Service Bulletins

While there are no specific NHTSA recalls for the steering column control module itself, Genesis has issued related software updates and recalls for the GV80 that owners should be aware of.

• Steering Wheel Remote Controller (SWRC) Free Repair: Genesis issued a notice for a free software upgrade for some 2024 GV80 models (and other Genesis vehicles) manufactured between October 2023 and May 2024. The issue involves potential voltage instability when starting the vehicle in high temperatures, which could cause the steering wheel button lights to fail or the buttons to malfunction. This update is performed over-the-air (OTA) for vehicles with Genesis Connected Services and does not require a dealer visit.
• Instrument Panel Software Issues: Several recalls and OTA updates have been issued for instrument panel software that can cause the display to go blank, hiding critical information like the speedometer. While not directly a fault of the steering column module, these systems are interconnected, and a blank display can be a symptom of various electronic issues.
• Seat Belt Pretensioner Recall: A major safety recall (NHTSA Campaign Number: 23V-094) affects 2021-2023 GV80 models. The front seat belt pretensioners can explode upon deployment in a crash, potentially causing injury from metal fragments. Dealers will install a protective cap on the pretensioners free of charge. This is unrelated to the steering column module but is a critical safety repair for all owners.

Symptoms of a Failing Steering Column Control Module

A faulty steering column control module can manifest in several ways, ranging from minor annoyances to significant safety concerns.

• Power Tilt/Telescoping Failure: The most common symptom is the power steering column getting stuck in one position. It may fail to move with the manual control switch or not retract/return to the memory position. Often, you won't hear the motor attempting to engage, pointing to an electrical or control issue.
• Steering Wheel Buttons Not Working: Cruise control, audio volume, phone, and other steering-wheel-mounted buttons may become unresponsive or work intermittently.

• Warning Lights: A fault in the module can trigger various warning lights on the instrument cluster, including the airbag light, as the module is a key part of the supplemental restraint system (SRS).
• Intermittent Electrical Issues: You might experience wipers, turn signals, or headlights behaving erratically, as these systems are often routed through the steering column module and its associated clock spring.
• Hard or Stiff Steering: In vehicles with electric power steering, a failing control module can sometimes lead to a loss of power assist, making the steering feel unusually heavy.

Associated OBD-II Codes

A professional scan tool that can read Body (B-prefix), Chassis (C-prefix), and Network (U-prefix) codes is necessary for proper diagnosis. While specific codes can vary, failures in this system may be indicated by codes related to lost communication with the Body Control Module (U0140), steering column lock failure (B1978), or other specific sensor and switch circuit faults.

Programming and Calibration Requirements

Yes, this module will almost certainly require programming to function correctly after installation. This is not a simple plug-and-play part. The module needs to be configured to the vehicle's specific options and VIN. This process, often called 'variant coding' or 'programming,' ensures that all functions, especially the power tilt/telescope with memory, work as intended. Failure to program a replacement module can result in non-functional features or persistent error codes.

While some advanced independent shops with high-end diagnostic tools may be able to perform the programming, a Genesis dealership is the most reliable option to ensure it is done correctly. There is no known link to the immobilizer, so the vehicle should still start with an unprogrammed module, but key functions will be disabled.

Buying a Used Steering Column Control Module

Purchasing a used OEM module is a cost-effective way to restore functionality, especially since aftermarket options are not available for this part. Here’s what to look for:

• Match the Part Number Exactly: This is the most critical step. There are two primary part numbers: 95490-T6000 (for vehicles built up to 03/14/2022) and 95490-T6001 (for vehicles built from 03/15/2022). Part number 95490-T6001 supersedes 95490-T6000. Using the wrong part number will likely result in incompatibility.
• Verify Vehicle Options: This module is specifically for GV80 models equipped with a power tilt and telescoping steering column with a memory function. Ensure the donor vehicle had the same features.
• Inspect for Damage: Check all electrical connector pins for any signs of bending, corrosion, or damage. Look at the plastic housing for cracks or signs of water intrusion.
• Budget for Programming: Remember to factor in the cost of professional programming. A used module cannot be installed without this step.
