2016-2017 Kia K900 Steering Column: Diagnosing Power Adjust Failures, Noises, and Recalls

Symptoms of a Failing 2016-2017 K900 Steering Column

Because the K900's steering column is both mechanical and electronic, failures can appear in several ways. Some symptoms point to the main column assembly, while others may indicate a problem with a related, but separate, part.

• Power Tilt or Telescopic Functions Fail: The most common issue specific to this column is the failure of the power adjustment motors. The steering wheel may get stuck in one position or refuse to move when you use the adjustment switch.
• Grinding or Clicking Noises: A clicking or grinding sound when turning the wheel, especially at low speeds, can be a sign of a worn internal component. In many Kia and Hyundai vehicles, this is caused by a small, inexpensive rubber part called a flexible steering coupler that degrades over time.
• Steering Wheel Feels Loose or Has Play: Excessive looseness or a clunking sensation felt through the steering wheel can indicate worn universal joints (U-joints) in the column shaft or a problem with the connection to the steering rack.
• Vibrations in the Steering Wheel: A shaking steering wheel could be caused by a misaligned or binding joint within the column. One K900 owner reported the steering wheel shaking and the vehicle shutting down entirely.
• EPS or ESC Warning Light: An illuminated Electric Power Steering (EPS) or Electronic Stability Control (ESC) light on your dashboard is a serious warning. It often points to a failure of the Steering Angle Sensor or Torque Sensor within the column assembly. Diagnostic Trouble Codes (DTCs) like C1290 (Torque Sensor Error) or C1259 (Steering Angle Sensor Signal Error) can confirm this.
• Malfunctioning Controls: If your headlights, turn signals, or wipers stop working, the issue is likely the multifunction switch assembly, not the entire column. Similarly, if the airbag light is on or the steering wheel buttons (horn, audio, cruise control) fail, the problem is typically the clock spring.

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

While no recalls have been issued for the main steering column assembly on the 2016-2017 K900, there is a critical recall for a part attached to it.

Recall SC130: Multifunction Light Switch Failure

Kia issued a recall for the multifunction light switch on the 2016 K900. The switch, when left in the "AUTO" position, could malfunction and cause the headlights to turn off while driving, increasing the risk of a crash. The remedy is for a Kia dealer to replace the multifunction switch (part number 93400-3T141) free of charge. If you are experiencing headlight issues, this recall should be your first check.

Technical Service Bulletin CHA084

Kia released a TSB related to diagnosing and repairing Motor Driven Power Steering (MDPS) systems. It provides technicians with a flowchart for troubleshooting issues based on DTCs. This bulletin is important because it advises against replacing the entire steering column assembly when only a smaller component like the ECU, motor, or worm gear has failed.

Buying a Used 2016-2017 K900 Steering Column: What to Check

Given the high cost of a new OEM column, a used part from a reputable recycler is a smart choice. However, this is a complex part, and careful inspection is key.

1. Verify Compatibility Above All Else

The single most important factor is ensuring the used column is from a vehicle with the power tilt and telescopic adjustment feature. The 2016-2017 K900 was equipped with this, so you must get a column with the correct motors and wiring. The primary OEM part number for the correct assembly is 56300-3T200. Always double-check the part number before purchasing.

2. Physical Inspection Checklist

• Connectors and Wiring: Carefully inspect all electrical connectors. Look for any bent pins, cut wires, or signs of heat damage (melted plastic). A damaged harness can be impossible to repair correctly.
• Main Shaft and U-Joints: Check the column shaft for any bends, cracks, or heavy corrosion, which could indicate it came from a crashed vehicle. Hold the ends of the shaft and try to rotate the universal joint. It should move smoothly without binding or feeling loose.
• Mounting Points: Ensure all mounting brackets are intact and not bent or cracked.
• Ask About Noises: If possible, ask the seller if the donor car had any clunking or clicking noises when turning. This could point to a bad flexible coupler, which you may need to replace.

3. Mileage and Source Vehicle

Choose a column from a lower-mileage vehicle if possible. Since the internal motors and sensors have a finite life, lower mileage means less wear. A part from a vehicle that was in a rear or side collision is generally preferable to one from a major front-end impact, which could have transmitted force up the steering column.

Cost of Replacing a 2016-2017 Kia K900 Steering Column

Replacing the steering column is an expensive repair, primarily due to the cost of the part and the intensive labor required.

Installation and Calibration Requirements

The replacement difficulty is high, rated at a 5 out of 5. The process involves disconnecting the battery, carefully removing the steering wheel and airbag, disconnecting multiple electrical harnesses, and unbolting the column from the dashboard support and the intermediate shaft.

Mandatory Steering Angle Sensor (SAS) Calibration

After the new column is installed, the Steering Angle Sensor must be calibrated using a professional-grade diagnostic scan tool. This procedure tells the car's computer the new sensor's straight-ahead position. If you skip this step, the Electronic Stability Control (ESC) and power steering systems will not function correctly, creating a serious safety risk. The car may pull to one side, or the ESC may activate improperly, potentially causing a loss of control.
