What Causes 2017 Chevy Traverse Power Steering Problems?
If you are trying to figure out how to fix 2017 Chevy Traverse power steering problems, the first step is understanding that “power steering” complaints can come from several different systems.
On the 2017 Chevrolet Traverse, steering assist can feel heavy, intermittent, noisy, or completely unavailable when the issue is electrical, mechanical, or low-voltage related.
This model year uses an electric power steering system rather than a traditional hydraulic pump-and-fluid setup.
That means the main clues often point to sensors, wiring, the steering column assist motor, or battery and charging issues rather than fluid leaks.
Common Symptoms You May Notice
Before replacing parts, match the symptom to the likely failure area.
That helps narrow the diagnosis and avoids unnecessary repairs.
- Steering wheel feels stiff, especially at low speeds
- Assist cuts in and out while driving
- Warning light for power steering or stability control appears
- Clicking, whining, or grinding from the steering column
- Steering effort changes after a battery replacement or jump-start
- Vehicle pulls or feels unstable because the wheel does not center smoothly
Many owners mistake an alignment issue for a power steering failure.
Alignment problems can affect steering feel, but they do not usually cause an electronic assist warning light.
Check the Battery and Charging System First
Low voltage is one of the most common reasons electric power steering behaves erratically on the 2017 Chevy Traverse.
The electric assist motor and related modules need stable voltage to function correctly.
What to inspect
- Battery age and condition
- Corroded or loose battery terminals
- Alternator output
- Ground connections
- Blown fuses related to steering or ignition circuits
Use a multimeter if possible.
A healthy resting battery should typically read around 12.6 volts, and charging voltage with the engine running is usually in the 13.5 to 14.8 volt range.
If voltage drops during cranking or idle, the steering assist module may shut down to protect the system.
If the battery is weak, replace it before chasing steering components.
A failing battery can trigger false steering warnings, especially after cold starts.
Scan for Diagnostic Trouble Codes
A professional-grade scan tool is one of the fastest ways to diagnose this problem.
Generic OBD-II readers often miss steering-specific codes stored in the electric power steering module, body control module, or stability control system.
Useful code categories
- Steering assist motor or torque sensor faults
- Low voltage or communication errors
- Ignition or module power supply issues
- Wheel speed or yaw sensor-related faults that affect steering behavior
Do not clear codes before writing them down.
Freeze-frame data can show whether the issue happened during startup, while turning, or when voltage dropped below normal.
Inspect Fuses, Wiring, and Connectors
Because the Traverse uses electronic steering assist, damaged wiring can create symptoms that look like a major steering failure.
Heat, vibration, moisture, and prior repairs can all affect connectors around the steering column and under the hood.
Look for these problems
- Loose or bent connector pins
- Water intrusion or green corrosion
- Chafed wiring harnesses
- Blown steering-related fuses
- Poor grounds near the battery or chassis
Gently wiggle-test visible harnesses while observing system behavior if you have a scan tool.
If the assist returns or the warning light flickers, you may have an intermittent wiring fault.
Test the Electric Power Steering Motor and Torque Sensor
The steering column assembly on many GM vehicles combines the assist motor, torque sensor, and control electronics into one integrated system.
If either the motor or sensor fails, steering effort can become heavy or unpredictable.
A torque sensor tells the system how hard you are turning the wheel so it can provide the correct amount of assist.
If that signal is inaccurate, the system may reduce or disable assist entirely.
Signs of a failing column assembly
- Assist disappears after startup or during turns
- Uneven steering effort left to right
- Intermittent warning messages
- Electrical noises from the column
In many cases, the entire steering column assist unit or related assembly may need replacement rather than a single internal part.
That is why accurate diagnosis matters before buying expensive components.
Look for Mechanical Steering Problems Too
Not every steering complaint comes from electronics.
Worn suspension and steering parts can create a heavy or vague steering feel that mimics power steering trouble.
Mechanical items to inspect
- Outer and inner tie rods
- Ball joints
- Struts and strut mounts
- Control arm bushings
- Steering rack mounting points
If front-end parts are loose or binding, the steering wheel may feel hard to turn even when the electric assist system is working properly.
Have the front end lifted and checked for play, binding, or uneven resistance side to side.
Check for Software Updates and Relearn Procedures
On modern GM vehicles, steering systems may require calibration or software updates after certain repairs, battery disconnects, or module replacements.
A scan tool can reveal whether the steering angle sensor, torque sensor, or related modules need a relearn.
If the steering wheel was recently replaced, the battery disconnected for an extended period, or the column assembly serviced, a relearn procedure may restore normal operation.
Dealer-level software through GM service tools or a capable independent shop may be required.
How to Fix 2017 Chevy Traverse Power Steering Problems Step by Step
If you want a practical repair path, follow this order so you do not replace parts unnecessarily:
- Check battery health and charging voltage.
- Inspect fuses, grounds, and visible wiring.
- Scan all modules for steering-related trouble codes.
- Confirm whether the symptom is electrical or mechanical.
- Test front-end suspension and steering linkage for binding or looseness.
- Perform any required sensor relearns or calibrations.
- Replace faulty components such as the battery, wiring repair sections, steering column assembly, or related modules if diagnosis confirms failure.
This sequence is especially useful because many steering complaints on the 2017 Traverse begin with low voltage or communication faults, not a destroyed steering rack.
When the Steering Column Assembly Needs Replacement
If codes and testing point to the electric assist motor, torque sensor, or internal column electronics, replacement may be the correct fix.
Depending on mileage and repair history, symptoms can become more frequent until assist is lost completely.
Because this is a safety-related system, avoid driving long distances if steering assist is failing intermittently.
A sudden loss of assist can make the vehicle difficult to control at low speed, parking speeds, or during emergency maneuvers.
Repair Cost Factors to Expect
Costs vary widely based on the root cause.
A battery replacement is far cheaper than a steering column assembly or module repair.
- Battery or terminal service: usually the lowest-cost repair
- Wiring or connector repair: moderate, depending on labor time
- Software update or relearn: often less expensive than hardware replacement
- Steering column or assist component replacement: typically the most expensive path
Labor rates, parts availability, and whether calibration is needed will affect total cost.
An accurate diagnosis often saves more money than any single repair choice.
What to Do If the Problem Comes Back
Intermittent steering problems are often the hardest to solve because they can disappear during a shop visit.
If the issue returns after a battery replacement or minor repair, ask for a load test, module scan, and voltage drop test rather than a quick visual inspection.
Document when the issue happens: cold weather, after rain, during parking, after highway driving, or after the vehicle has sat overnight.
Those patterns can point to voltage instability, moisture intrusion, or a failing internal steering component.
Signs You Should Not Ignore
- Loss of steering assist while moving
- Repeated steering warnings after a new battery installation
- Grinding or clicking from the column
- Visible smoke, burning smell, or electrical overheating
- Steering wheel binding or not returning to center
If any of these are present, have the vehicle inspected promptly by a qualified technician.
Power steering issues affect control, not just comfort, and early diagnosis is usually the safest and most cost-effective approach.
