2019 Kia Cadenza Steering Column: Diagnosing Noises, Power vs. Manual, and Replacement Guide

Key Differences in 2019 Kia Cadenza Steering Columns

Before diagnosing issues or buying a replacement, it's crucial to know that the 2019 Cadenza uses two different steering columns. They are not interchangeable. The primary difference is the tilt and telescopic adjustment method.

Common Symptoms of a Failing Steering Column

A problem with the steering column can manifest in several ways. Some are minor annoyances, while others can be serious safety concerns.

• Clicking or Knocking Noise When Turning: This is one of the most common symptoms. A distinct clicking, popping, or knocking sound when turning the wheel, especially when stopped or at low speeds, often points to a worn flexible coupler inside the MDPS motor. While this part is small, it often requires significant labor to access.
• Scraping or Grinding Noise: A TSB for the 2018-2021 Cadenza specifically mentions a scraping noise caused by a faulty bearing in the MDPS worm shaft. This is a distinct issue from the flexible coupler.
• Steering Wheel Vibration: A shaky or vibrating steering wheel can indicate worn bearings or loose components within the column assembly.
• Loss of Power Steering: The steering may suddenly become very heavy and difficult to turn, either intermittently or permanently. This indicates a failure in the MDPS motor or its control module. An EPS (Electronic Power Steering) warning light will likely illuminate on the dashboard.
• Tilt Adjustment Failure: The steering wheel may no longer lock into place after being adjusted for height or reach.
• Rough or Binding Steering: If the steering feels like it's catching or binding at certain points as you turn, it could be caused by a failing universal joint or worn internal bearings.

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

As of mid-2024, there are no specific recalls for the steering column assembly on the 2019 Kia Cadenza. However, there are related service bulletins and recalls for the vehicle that are important to know.

• TSB CHA111: This bulletin directly applies to the 2018-2021 Cadenza and addresses an abnormal scraping noise from the C-MDPS (Column-MDPS) unit. The cause is identified as foreign substances in the worm shaft bearing. The prescribed fix is to replace the small bearing, not the entire steering column, which can save significant cost.
• Common MDPS Flexible Coupler Wear: While not a specific TSB for the 2019 Cadenza, numerous other Kia and Hyundai models have warranty extensions and service campaigns for a worn flexible coupler that causes a clicking noise. This part is a known weak point in the MDPS system.
• Vehicle Recall SC206 (NHTSA 21V-137): This important safety recall affects 2017-2021 Cadenzas. It involves a potential electrical short in the Hydraulic Electronic Control Unit (HECU) that can cause an engine compartment fire, even when the car is off. This is unrelated to the steering column but is a critical safety issue for all owners.

Buyer's Guide: What to Check Before Purchasing a Used Steering Column

Buying a used OEM steering column is often the most cost-effective solution. Because aftermarket options are rare for this model, a quality recycled part is a great choice. Here’s what to look for.

1. Confirm the Type: This is the most critical step. Verify if your Cadenza has the power tilt/telescopic or manual tilt/telescopic column. They are not interchangeable. Ask the seller to confirm which type the donor car had.
2. Match Part Numbers if Possible: While several part numbers may work, the safest bet is to match the number from your original column. If you can't see the number, matching the features (power vs. manual) is the next best thing.
3. Inspect All Electrical Connectors: Carefully check every electrical plug on the column. Look for cut wires, bent pins, or signs of corrosion (green or white powder). Damaged connectors are a major red flag and can be very difficult to repair.
4. Check for Physical Damage: Look down the length of the main shaft to ensure it is straight and not bent. Inspect the housing for cracks or damage, which could indicate the donor vehicle was in a severe collision.
5. Ask About the Donor Vehicle: Inquire about the mileage of the vehicle the part came from. Lower mileage is always better. Also, ask if the vehicle had front-end or flood damage. Avoid columns from flood-damaged cars, as moisture can ruin the integrated electronics.
6. Understand What's Included: Clarify if the sale includes the multi-function switch and clock spring. Sometimes these are sold separately. The core part you need is the column with the MDPS motor and control module.

Replacement Overview and Programming

Replacing the steering column is an advanced procedure that requires care, especially when handling the airbag system.

• Difficulty: 4 out of 5. This job is complex and involves safety-critical components.
• Key Steps: The general process involves disconnecting the battery, removing the driver's airbag module, steering wheel, and clock spring/multi-function switch. Then, the column covers are removed, electrical connectors are unplugged, and the column is unbolted from the dash support and the intermediate shaft U-joint in the footwell.
• Programming is Required: After installation, the new column's electronic modules must be synced with the vehicle. A Steering Angle Sensor (SAS) calibration is mandatory. This procedure tells the car's stability control system where the steering wheel is pointed. Failure to calibrate the SAS will result in a warning light and disabled stability control, which is a major safety risk. This calibration requires a professional-grade scan tool.

Cost Comparison

The cost to replace a 2019 Cadenza steering column can vary significantly based on the part source and labor rates.
