How 2016 Chevy Traverse Power Steering Problems Show Up
If you are trying to figure out how to fix 2016 chevy traverse power steering problems, the first step is identifying the exact symptom.
On the 2016 Chevrolet Traverse, steering complaints can range from a stiff wheel at low speed to intermittent loss of assist, warning messages on the instrument cluster, or a steering feel that changes suddenly while driving.
These symptoms often point to an issue in the electric power steering system, the charging system, or the steering control module.
Because the Traverse uses electronic assist rather than a hydraulic pump, the root cause is often electrical, not mechanical.
- Steering wheel feels heavy, especially at parking speeds
- Power steering warning light or “Service Power Steering” message appears
- Assist works sometimes and then drops out
- Steering feels jerky, notchy, or inconsistent
- Battery or charging issues appear at the same time
What System Does the 2016 Traverse Use?
The 2016 Chevy Traverse uses an electric power steering system, commonly referred to as EPS.
Instead of a hydraulic pump driven by the engine, an electric motor provides steering assist based on signals from sensors, the steering column, and the vehicle control network.
This matters because many drivers search for a pump leak or fluid issue that does not exist on this model.
The most common failure points are the electric assist motor, torque sensor, steering column components, wiring, fuses, relays, the battery, and the alternator.
A weak electrical supply can cause the system to reduce or shut off assist to protect itself.
Check the battery and charging system first
Before replacing steering parts, verify that the battery and alternator are working correctly.
EPS systems are sensitive to low voltage, and a weak battery can trigger steering warnings even when the steering hardware is fine.
Use a multimeter to check battery voltage with the engine off and running.
A healthy battery should typically read around 12.6 volts at rest, and the charging system should usually produce roughly 13.5 to 14.7 volts with the engine running.
If voltage is low or unstable, fix that issue first.
- Inspect battery terminals for corrosion or looseness
- Check ground connections at the battery and chassis
- Test alternator output under load
- Look for voltage drops when turning the wheel
If the Traverse has a failing battery, poor terminals, or a weak alternator, the steering assist may return after the electrical problem is repaired.
Inspect fuses, relays, and wiring
Next, inspect the fuses and wiring related to the power steering circuit.
A blown fuse can disable assist immediately, while a damaged harness can create an intermittent problem that is harder to catch.
Pay attention to areas where wiring may rub, bend, or absorb moisture.
Use the owner’s manual or fuse box diagram to locate EPS-related fuses.
Replace only with the correct amperage rating, and investigate the reason for the failure if a fuse has blown.
If the fuse fails again, there may be a short circuit or a failing steering component drawing too much current.
- Check for frayed insulation or pinched wires
- Inspect connectors for corrosion or water intrusion
- Verify grounds are clean and tight
- Confirm relays click and function as intended
Read diagnostic trouble codes with a scan tool
A professional-grade scan tool is one of the fastest ways to narrow down the problem.
Generic code readers may miss EPS-specific data, while a GM-capable scan tool can read codes from the steering control module and related systems.
Common fault categories include torque sensor faults, steering angle sensor issues, low-voltage events, or internal EPS motor failures.
Record all codes before clearing them, because history codes can point to an intermittent electrical fault that no longer appears during testing.
Important live data to review includes battery voltage, steering angle, torque sensor output, and assist command values.
If the module sees impossible sensor readings, it may disable assist even when the steering motor is still functional.
How to tell whether the steering column is failing
On many Traverse models, the steering column assembly is a likely repair when EPS faults are confirmed.
The torque sensor, assist motor, or internal electronics may fail together, depending on the exact design and mileage.
Signs of a failing steering column or EPS unit include a persistent warning message, assist that drops out after startup, or steering effort that changes with road vibration or temperature.
If the electrical supply is healthy and the codes point to internal steering faults, the column assembly may need replacement.
- Assist fails after the vehicle warms up
- Steering feels normal one moment and heavy the next
- Codes return immediately after clearing
- No improvement after battery and wiring repairs
Reset the system after repairs
After fixing the underlying issue, the steering system may need a relearn or calibration procedure.
Depending on the fault, that can include clearing codes, performing a steering angle sensor calibration, or completing an EPS reset with a compatible scan tool.
Do not assume a warning light means the repair failed until the system has been properly calibrated.
Some faults remain stored until the module sees a complete drive cycle and stable voltage conditions.
When a simple reset helps
A reset may help if the warning was caused by low battery voltage, a temporary communication glitch, or a code that set during engine start.
However, a reset is only a short-term fix if the root cause still exists.
Common repair options and what they usually involve
The right repair depends on what the diagnostic process shows.
In some cases, the fix is as simple as a battery replacement or cleaning a ground connection.
In others, the steering column assembly or wiring harness must be repaired or replaced.
- Battery replacement: useful when the battery cannot hold charge or voltage drops during cranking
- Alternator repair: needed when charging output is unstable or low
- Fuse, relay, or wiring repair: appropriate for electrical interruptions or shorts
- Steering column replacement: often required for confirmed EPS motor or torque sensor failure
- Module calibration: may be required after major steering repairs
Labor and part costs can vary widely depending on whether the issue is electrical or mechanical.
A basic electrical repair may cost far less than replacing the entire steering column assembly.
Driving safety and when to stop driving
Because steering assist loss can make the vehicle difficult to control at low speeds, treat repeated power steering failures seriously.
If the wheel becomes suddenly heavy, pulls to one side, or the warning message appears while driving, reduce speed and inspect the vehicle before continuing long distances.
Stop driving immediately if steering effort becomes extreme, the warning light remains on after restarting, or the issue comes with other electrical symptoms such as dim lights, stalling, or repeated battery drain.
What to remember when diagnosing the problem
For the 2016 Chevy Traverse, power steering complaints are often caused by low voltage, bad grounds, failed sensors, or an internal EPS problem.
The most efficient approach is to check the battery and alternator first, inspect fuses and wiring, scan for diagnostic trouble codes, and only then consider steering column replacement.
Following that sequence prevents unnecessary parts replacement and helps isolate the real failure faster, especially when the steering problem appears only intermittently.
Useful checks before visiting a mechanic
- Note when the problem happens: cold start, rain, bumps, or low-speed turns
- Record any dashboard warnings or codes
- Test battery voltage and charging output
- Inspect visible wiring and terminals
- Confirm whether the steering assist returns after a restart
These details can help a technician confirm whether the issue is electrical, module-related, or a failed steering component, which speeds up the repair process and reduces guesswork.
