2017-2022 Chevrolet Trax Steering Column: Failure Symptoms and the Critical Key vs. Keyless Difference

Common Symptoms of a Failing Trax Steering Column

A problem with the steering column can manifest in several ways, ranging from annoying noises to a complete loss of power steering. Because the column integrates electrical and mechanical parts, symptoms can be varied.

• Loss of Power Steering: The most serious symptom is a sudden or intermittent loss of power steering assist. The steering will become very heavy and difficult to turn, particularly at parking lot speeds. This is often accompanied by a "Service Power Steering" message on the instrument panel.
• Noises When Turning: You may hear clicking, grinding, clunking, or squeaking noises coming from the steering wheel area when you turn. While other suspension parts can cause noises, sounds that seem to come from directly behind the steering wheel often point to the column's internal bearings or the clock spring.
• Vibrations or Looseness: A worn bearing or internal joint can cause a loose feeling or vibration in the steering wheel. The steering may feel less precise or have excessive play.
• Binding or Sticking: The steering wheel may feel like it's binding or getting stuck at certain points in its rotation. Some Trax owners have reported the wheel feeling stuck or not returning to its center position after a turn.
• Non-Functioning Controls: If the buttons for the radio or cruise control on your steering wheel stop working, it could be due to a failed clock spring, which is housed within the column assembly.
• Warning Lights: An illuminated power steering warning light or traction control/StabiliTrak light can be triggered by a fault in the column, often related to the steering angle sensor.

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

While there are no steering column-specific recalls for the 2017-2022 Trax, there is a very important Technical Service Bulletin (TSB) that owners and technicians should be aware of.

TSB 20-NA-111: Service Power Steering Message & DTC U0100

Some 2017-2022 Trax vehicles may display a "Service Power Steering" message and log a diagnostic trouble code U0100 (Lost Communication With ECM/PCM) in the Power Steering Control Module (PSCM). This can cause a loss of power steering assist.

The cause is often an internal failure in the Body Control Module (BCM) that leads to a short circuit. This short can damage the steering column's electronics. In these cases, simply replacing the steering column will not fix the problem long-term; the new column may soon fail as well. The proper repair requires diagnosing the BCM and replacing it along with the steering column if necessary.

Buying a Used 2017-2022 Trax Steering Column: A Buyer's Guide

A used OEM steering column can be a cost-effective solution, but careful verification is essential to get the right part and avoid compatibility headaches. New aftermarket column assemblies for this model are not widely available, making used OEM a popular choice.

The Most Important Check: Key vs. Keyless Ignition

The single most important factor when buying a used column is matching it to your vehicle's ignition system. The columns are different and are not interchangeable.

• Conventional Key Ignition: For models where you insert a physical key to start the car. The correct OEM part number is typically 42734405.
• Keyless Push-to-Start: For models with a push-button start system. The correct OEM part number is typically 42734407.

Before purchasing, visually compare the ignition area of the donor column to your original. A seller should be able to provide the VIN of the donor vehicle, which can be used to confirm its options.

Physical Inspection Checklist

• Connectors and Wiring: Inspect all electrical connectors for cracks, broken tabs, or corrosion. Ensure the wiring harness has not been cut or poorly repaired.
• Shaft Condition: Look down the length of the column shaft. It should be perfectly straight with no signs of bending from a collision.
• No Physical Damage: Check the housing for cracks or signs of impact. Avoid any parts from vehicles that have been in a major front-end collision or fire.
• Smooth Rotation: The input shaft should turn smoothly without any grinding or binding.

Cost of Replacement: 2017-2022 Chevrolet Trax Steering Column

The cost can vary significantly based on the parts source and labor rates. The electric power steering motor and control module are part of the column assembly, which drives up the cost of the part.

Replacement Overview & Calibration

Replacing the steering column is a complex job best left to experienced DIYers or professional technicians due to the safety systems involved.

The general process involves removing the steering wheel airbag, the steering wheel itself, the plastic shrouds around the column, disconnecting all electrical harnesses, and unbolting the column from the dashboard support structure and the intermediate steering shaft.

Required Calibration

After the new column is installed, the Steering Angle Sensor (SAS) must be calibrated using a compatible diagnostic scan tool. This procedure tells the vehicle's computer the exact position of the steering wheel. Skipping this step will cause the stability control (StabiliTrak) system to malfunction and will likely leave warning lights on the dash.
