Symptoms

Owners of certain 2022 Hyundai Tucson (NX4A) vehicles may notice a Hyundai Tucson steering shimmy specifically at highway speeds. This vibration or shimmy in the steering wheel is distinct from issues caused by tire balance or radial force variation (RFV).

Fault Codes / OEM Fault Labels

While no traditional Diagnostic Trouble Codes (DTCs) are explicitly listed, this issue is associated with a specific GDS (Global Diagnostic System) Event. Technicians may identify this condition under:

  • Event # 814: "NX4A STEERING WHEEL VIBRATION IMPROVEMENT W/O BRAKING"

This event description directly relates to the Hyundai Tucson steering shimmy that owners might experience.

Diagnosis / Trigger Conditions

The steering wheel shimmy typically occurs at highway speeds. It's important to note that this condition is not attributed to common causes like improperly balanced tires or variations in tire radial force. The underlying cause is related to the anti-shimmy logic within the Motor Driven Power Steering (MDPS) ECU.

Important Warnings for Owners and Technicians

Hyundai has issued specific warnings regarding the software update process:

  • GDS ECU Update Mode: The GDS ECU Update must initially be performed in Auto Mode. If the update begins but then fails in Auto Mode, technicians are instructed to perform the update in Manual Mode to recover the system.
  • Battery Low Voltage Warning: A critical warning, "GDS-M Vehicle Battery Low Voltage Warning," will trigger if the vehicle battery voltage drops below 12 volts during the update. If this occurs, the technician must either connect a fully charged battery jump pack or GR8 charger in "Power Supply Mode" to continue the update, or exit the software update, idle the engine with headlights on for 20 minutes to charge the battery, and then restart the update. The verbatim message displayed is: "Warning! lower Battery Voltage. BATTERY VOLTAGE: 11.7"

Repair Procedure Summary

The resolution for the Hyundai Tucson steering shimmy involves updating the anti-shimmy logic in the Motor Driven Power Steering (MDPS) ECU. This is performed using the Hyundai Global Diagnostic System (GDS).

  1. Software Update: Technicians will perform a GDS software update on the MDPS ECU. For detailed tablet-based Mobile GDS ECU update procedures, reference TSB 15-GI-001.
  2. DTC Check and Erase: After the software update, all diagnostic trouble codes across all vehicle menus must be checked and erased.
  3. Operation Confirmation: The final step is to confirm normal vehicle operation to ensure the steering wheel shimmy is resolved.

ROM ID Table

The software update changes the ROM ID of the MDPS system:

MODEL SYSTEM PART NUMBER OLD ROM ID NEW ROM ID
