2015-2016 Chevrolet Trax Steering Column: Recall, Noises, and Replacement Guide

Safety Recall Alert: Sudden Loss of Power Steering

Symptoms of a Failing Steering Column

A failing steering column in a 2015-2016 Trax can present several distinct symptoms. Pay close attention to these signs, as some indicate a serious safety risk.

1. Sudden Difficulty Steering

The most critical symptom is a sudden loss of power steering assist. The steering wheel will become very heavy and difficult to turn, especially at low speeds. This is often accompanied by the power steering warning light illuminating on the dashboard. This is the primary symptom related to the 2015 model year recall.

2. Clicking, Clunking, or Grinding Noises

Unusual noises when turning the steering wheel often point to internal mechanical problems. Owners have reported clicking noises coming from the steering column area. While clunking noises can also be caused by other suspension components like ball joints or sway bar links, a noise isolated to the column itself warrants immediate inspection.

3. Steering Wheel Vibrations

A shaking or vibrating feeling in the steering wheel as you drive can be a sign of loose or worn components within the column. This might be caused by worn bearings or a problem with the intermediate shaft connection.

4. Failure of Steering Wheel Controls

If your radio controls, cruise control, or horn stop working intermittently or altogether, the problem could be a faulty clock spring inside the steering column. The clock spring is a special rotary electrical connector that allows the steering wheel to turn while maintaining a connection for all the electronic controls and the airbag.

Buying a Used 2015-2016 Trax Steering Column: What to Check

Purchasing a used OEM steering column can be a cost-effective solution, but careful inspection is key. Given the integrated electronics, a quality recycled OEM part is often a more reliable choice than a new, unproven aftermarket unit.

• Verify Recall Status: If possible, get the VIN of the vehicle the column came from and check if the GM recall #15168 has been performed. A part that has already been replaced under the recall is ideal.
• Match Part Numbers and Options: The Trax was available with different features. Ensure the replacement column has the exact same options as your original, specifically controls for cruise control, radio functions, and the driver information display. The part numbers 94745683, 95238402, 95326317, and 95442049 are associated with this assembly and its components.
• Inspect Wiring and Connectors: Check all wiring harnesses and plastic connectors for damage. Bent pins, cut wires, or cracked connector housings will cause installation headaches and electrical failures.
• Check for Physical Damage: Look for any signs of impact damage, such as a bent main shaft or cracks in the housing. A column from a vehicle in a major front-end collision should be avoided.
• Test Rotation: Turn the steering shaft by hand. It should rotate smoothly without any grinding, binding, or excessive play.
• Confirm Included Components: Ensure the column comes as a complete assembly, including the turn signal and wiper stalks, as these can be difficult to swap over. Some used units may even come with the key and ignition cylinder.

Known Issues and Technical Service Bulletins (TSBs)

Beyond the major safety recall, GM has issued several TSBs related to steering performance:

• TSB #15-NA-015: Addresses a condition where the vehicle drifts or pulls to one side. The fix involves a technician using a scan tool to clear the learned limits in the power steering control module, not a part replacement.
• TSB #PIE-0334: Notes customer complaints of very hard steering and squeaking or squealing noises during cold weather on 2015 models.
• TSB #SB-16-NA-109: Clarifies that some grease seen on the outside of the steering gear is normal from the manufacturing process and should not be mistaken for a leak.

Replacement Cost & Difficulty

Replacing the steering column is an advanced job due to the need to handle the driver's airbag and the requirement for post-installation electronic calibration.

Steering Angle Sensor Calibration

After the new column is installed, the Steering Angle Sensor (SAS) must be calibrated. This sensor tells the Electronic Stability Control (ESC) and ABS systems which way the wheels are pointed. If it's not calibrated, the stability control light may stay on, and the system will not work correctly. This procedure requires a compatible professional-grade scan tool to set the sensor's zero-point position when the wheels are straight ahead.
