2016-2017 INFINITI Q50 Steering Column: Decoding Failures and Compatibility
This guide covers common symptoms, replacement costs, and critical compatibility checks for the standard steering column in 2016-2017 INFINITI Q50 models.
- Compatibility is critical: This column is for 2016-2017 Q50 RWD models WITHOUT Direct Adaptive Steering (DAS) and WITHOUT the Sport package.
- Electrical issues like an airbag light or failed steering wheel buttons usually point to a bad clock spring, which is a replaceable part of the column assembly.
- Replacement is an advanced job that requires careful handling of the airbag system and a steering angle sensor calibration with a professional scan tool afterward.
- Numerous steering recalls for the Q50 apply to the optional Direct Adaptive Steering (DAS) system and are not relevant to vehicles with the standard steering column.
Symptoms of a Failing Steering Column
Steering column issues can manifest as either mechanical or electrical problems. Recognizing the specific symptom is key to a correct diagnosis.
Electrical Failures (Clock Spring)
The most common failure point within the steering column assembly is the clock spring, also called a spiral cable. This part is a coiled ribbon of wires that allows the steering wheel to turn while maintaining a constant electrical connection for the driver's airbag, horn, and steering wheel-mounted controls (like audio and cruise control).
- Airbag Warning Light: An illuminated SRS (Supplemental Restraint System) light on the dashboard is the most serious symptom of a bad clock spring. This indicates a break in the connection to the driver's airbag, meaning it may not deploy in a crash.
- Inoperative Steering Wheel Buttons: Cruise control, radio volume, and phone control buttons on the steering wheel may stop working intermittently or altogether.
- Horn Not Working: The horn may fail to sound, or only work when the steering wheel is in a specific position. 🎬 Watch: Top 5 symptoms of a bad clock spring
Mechanical Failures
- Clicking, Grinding, or Binding Noises: Unusual sounds while turning the steering wheel can point to worn bearings or issues with the tilt/telescoping mechanism within the column.
- Excessive Play or Looseness: A feeling of looseness in the steering wheel that isn't related to the vehicle's suspension can indicate worn U-joints in the steering shaft or internal column wear.
- Stiff Steering: While often related to the power steering pump or rack, a binding or stiff feeling can sometimes originate from a damaged steering column.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
The 2016-2017 INFINITI Q50 was subject to several steering-related recalls, but these primarily concerned the optional Direct Adaptive Steering (DAS) system. This guide's specified part is for vehicles WITHOUT DAS. It is crucial to understand that these recalls for the 'steer-by-wire' system do not apply to the conventional electronic power steering column discussed here. There is a Technical Service Bulletin (ITB20-029) for some 2017-2020 Q50 models regarding a light or sensitive steering feel, which is addressed by a software reprogram.
Warning: The most critical factor when purchasing this part is ensuring your vehicle does NOT have Direct Adaptive Steering (DAS). DAS is a fully electronic 'steer-by-wire' system, whereas the part covered here is for the standard electronic power steering setup. The parts are not interchangeable.
Buying a Used 2016-2017 Q50 Steering Column
Purchasing a used OEM steering column can be a smart way to save money, as new OEM units are expensive and aftermarket electrical components can be unreliable. However, careful inspection and verification are essential.
How to Verify Compatibility
- Confirm Your Options: This specific column fits Rear-Wheel Drive (RWD) models only. It is for vehicles WITHOUT the Sport package and WITHOUT Direct Adaptive Steering (DAS).
- Check for Rain Sensor: This column is compatible with models equipped with a rain sensor. The rain sensor is located on the windshield near the rearview mirror mount. The combination switch (part of the column assembly) will have an 'Auto' setting on the wiper stalk if a rain sensor is present. 🎬 See how to identify if your car has rain-sensing wipers
- Match Part Numbers: Whenever possible, match the OEM part number from your original column to the replacement part. Key numbers include 480804HK0A (lower joint/shaft) and 255604GA7A (combination switch/clock spring assembly).
Physical Inspection Checklist
- Check Connectors: Inspect all electrical connectors for bent pins, corrosion, or cracks. Damaged connectors are a major red flag.
- Test Mechanical Movement: If possible, test the tilt and telescoping functions. They should move smoothly without binding or excessive noise.
- Inspect the Shaft: Look for any signs of bending, heavy corrosion, or damage to the universal joints (U-joints) on the lower shaft.
- Ask About the Donor Vehicle: Inquire about the mileage and condition of the vehicle the part came from. A column from a low-mileage, rear-ended vehicle is an ideal candidate. Avoid parts from flood-damaged cars.
Replacement Cost Comparison
Prices can vary based on supplier and location. The costs below are estimates to help understand the value of a used OEM part.
| Part Type | Estimated Cost |
|---|---|
| New OEM | $1100 - $1400+ |
| New Aftermarket | $400 - $700 (Quality and availability can vary) |
| Used OEM | $150 - $450 |
| Shop Labor | $230 - $600 |
Installation Overview
Warning: This procedure involves removing the driver's airbag. Improper handling can cause accidental deployment, leading to serious injury. This job should only be performed by qualified technicians or experienced DIY mechanics who follow all safety protocols.
Replacing the steering column is an advanced task.
- Disconnect the Battery: Disconnect the negative battery terminal and wait at least 15 minutes to allow the airbag system's backup power to discharge.
- Remove Airbag and Steering Wheel: The airbag module is released by pressing spring clips through access holes on the side of the steering wheel. After unplugging it, a central nut is removed to pull the steering wheel off the column shaft. 🎬 Watch this walkthrough for removing the airbag and steering wheel
- Remove Column Shrouds and Switches: Plastic shrouds around the column are removed, followed by the combination switch/clock spring assembly.
- Disconnect Lower Shaft: The column must be unbolted from its mounting bracket under the dash and from the intermediate steering shaft in the driver's footwell.
- Installation and Calibration: Installation is the reverse of removal. After installation, the steering angle sensor must be calibrated using a compatible professional scan tool to ensure the Vehicle Dynamic Control (VDC) system functions correctly.
Frequently Asked Questions (FAQ)
Can I replace just the clock spring instead of the whole column?
Yes. The clock spring, often sold as part of the combination switch assembly (e.g., part number 255604GA7A), can be replaced independently. This is a common repair if your only symptoms are electrical (airbag light, dead buttons, no horn).
What is Direct Adaptive Steering (DAS) and how do I know if I have it?
Direct Adaptive Steering is Infiniti's 'steer-by-wire' technology where there is no permanent mechanical link between the steering wheel and the wheels under normal operation. You can check your vehicle's original window sticker or use the Drive Mode Selector in the infotainment system; DAS allows you to change steering modes like 'Sport' and 'Sport+'. Vehicles without it have a standard, fixed-feel electronic power steering system.
Will a steering angle sensor reset be required after replacement?
Yes, it is highly recommended. Replacing the steering column or even just the clock spring will disturb the steering angle sensor's calibration. A reset is necessary for the proper function of the stability control (VDC) and other related systems. This requires a professional-grade diagnostic scan tool.
Is a loose or wandering steering feel caused by the steering column?
While possible, a wandering or loose feeling on the highway in a Q50 is more commonly attributed to other issues. Some owners have reported that loose sway bar locating rings can cause a side-to-side movement that translates into a vague steering feel. Always diagnose suspension and steering rack components before condemning the steering column for this symptom.
