2017 Kia Niro Power Steering Module: Recall, Codes, and Replacement Programming
Diagnose common steering faults, understand the critical programming requirements, and learn what to look for when buying a replacement module for your 2017 Kia Niro.
- A replacement module, new or used, will almost certainly require programming and steering angle sensor calibration by a dealer or specialized shop to function.
- A small number of 2017 Niros were recalled (SC145) for a bad MDPS connector, which can cause a sudden loss of power steering.
- Common failure codes include C1604 (ECU Hardware Error) and C2412 (Motor Voltage Supply Error).
- Buying a used OEM module (Part No. 56340-G5000) can save over $400 compared to a new part, but you must budget for professional installation and programming.
Known Issues: Recall SC145 for Damaged MDPS Connector
In March 2017, Kia issued a safety recall for a small number of 2017 Niro vehicles due to a power steering issue. The recall, known as NHTSA Campaign #17V159000 or Kia recall SC145, affected 135 vehicles built between December 23, 2016, and January 11, 2017.
The problem was a damaged Motor Driven Power Steering (MDPS) connector, which could cause a poor connection to the control module (ECU). This could result in a sudden loss of power steering assist, illuminating the EPS (Electronic Power Steering) warning light and making the vehicle difficult to steer, especially at low speeds. The official remedy was for Kia dealers to replace the entire MDPS motor assembly free of charge. While this recall only applied to a specific VIN range, it highlights a potential failure point in the system's wiring and connectors.
Symptoms of a Failing Power Steering Control Module
A failing power steering control module can make your Niro difficult or unsafe to drive. Watch for these specific signs:
- Sudden Heavy Steering: The most common symptom is an intermittent or complete loss of power steering assist. The steering wheel will suddenly become very difficult to turn, requiring significant physical effort.
- EPS Warning Light: A red steering wheel icon with an exclamation point will illuminate on your instrument cluster, indicating a fault in the MDPS system.
- Inconsistent Steering Feel: The steering may feel normal one moment and heavy the next, indicating an intermittent electronic failure.
- Vibration in the Steering Wheel: A failing module can send erratic signals to the motor, causing a shudder or vibration felt in the steering wheel, especially at low speeds or when stationary.
- Audible Noises: You might hear a clicking from the module's relays or a whining sound from the electric motor as it struggles to operate with incorrect commands.
Common Diagnostic Trouble Codes (DTCs)
If the EPS light is on, a code scanner can pull specific codes to help pinpoint the problem. Codes related to the power steering control module or its immediate system include:
| Code | Description | Common Cause |
|---|---|---|
| C1604 | ECU Hardware Error | Internal failure of the power steering control module. |
| C2412 | Motor Voltage Supply Error | Indicates a problem with the power supply to the MDPS motor, which can be caused by the module or wiring. |
| C1290 | Torque Sensor Error | Fault in the sensor that measures driver input; can be related to the module's interpretation of the signal. |
| C1704 | ECU Fail-Safe Relay Fault | A problem with an internal safety relay within the control module. |
| C1112 | Torque Sensor Voltage Error | Indicates a voltage problem in the torque sensor circuit, which the module monitors. |
Pro Tip: Before condemning the module, always check the battery and charging system. Low system voltage can cause the MDPS system to shut down and may trigger fault codes like C1102 (Battery Voltage Problem).
Programming and Calibration: This is NOT Plug-and-Play
Warning: A replacement Power Steering Control Module, whether new or used, will likely require programming and calibration to function correctly in your vehicle.
This is the most critical factor to understand before starting a repair. The module is tied to the vehicle's specific systems.
- Programming/Variant Coding: The module may need to be programmed with your vehicle's information to ensure it communicates correctly with other systems like the engine computer and ABS module. This procedure typically requires a dealer-level diagnostic tool, like the Kia Diagnostic System (KDS).
- Steering Angle Sensor (SAS) Calibration: After any work on the steering system, including module replacement, the steering angle sensor must be calibrated. This sensor tells the car which way the wheels are pointed. If it's not calibrated, it can disable the Electronic Stability Control (ESC) and cause other warning lights to appear.
While some high-end independent shops may have tools capable of these procedures, a visit to a Kia dealership is often required to complete the installation properly.
Buying a Used 2017 Niro Power Steering Module
Purchasing a used OEM module is an excellent way to save a significant amount of money. New OEM modules can cost over $550, while a quality used unit can often be found for under $150. Here’s what to look for:
- Verify the Part Number: Ensure the part is an exact match for the OEM number, 56340-G5000.
- Inspect the Connectors: The primary recall issue was a damaged connector. Carefully inspect all electrical pins and plastic housings on the used module. Look for any signs of corrosion, bent pins, or heat damage.
- Check Compatibility: This module fits 2017-2019 Kia Niro HEV (Hybrid) and PHEV (Plug-in Hybrid) models. It does NOT fit the all-electric Niro EV.
- Budget for Programming: When comparing costs, remember to factor in a potential 1-2 hours of labor at a dealership or qualified shop for programming and calibration.
- Why Used OEM is a Smart Choice: For complex electronics, a used OEM module is often more reliable than a new aftermarket part. It contains the original factory hardware and software designed specifically for your vehicle, which can prevent compatibility headaches even if programming is needed.
Cost Breakdown
Prices can vary by location and supplier, but here is a general estimate for replacing the Power Steering Control Module:
| Part/Service | Estimated Cost |
|---|---|
| New OEM Module | $560 - $850 |
| New Aftermarket Module | Not commonly available |
| Used OEM Module | $100 - $200 |
| Shop Labor (Replacement & Programming) | $250 - $450 |
FAQ
Can I drive my Niro with a bad power steering module?
It is not recommended. While you can still technically steer the car through manual force, the effort required is extremely high, especially during low-speed maneuvers like parking or turning in an intersection. This can make it difficult to react quickly in an emergency, increasing the risk of a crash.
Does a used power steering module need to be programmed?
Yes, it is very likely that a used module will need to be programmed or calibrated by a Kia dealer or a specialized independent shop. You should always assume this step is necessary and factor it into your repair plan and budget.
Where is the power steering control module located on a 2017 Kia Niro?
The Power Steering Control Module (ECU) is attached directly to the steering column assembly, located under the dashboard on the driver's side. Accessing it requires removing the lower dash panel and the knee airbag assembly.
What causes the power steering module to fail?
Failures are typically electronic. This can include internal issues like cracked solder joints, failed capacitors, or a hardware fault as indicated by code C1604. External factors like voltage spikes from a failing alternator or poor battery connections can also damage the module. In the case of the 2017 Niro recall, the issue was a poor physical connection at the main connector.
