How to diagnose and fix C0710: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Chevrolet Cobalt · 2005–2010
The Cobalt equipped with electric power steering (EPS) is subject to a recall for sudden loss of power steering assist while driving. The EPS motor can fail without warning at any speed, requiring significantly more effort to steer the vehicle. The 2005 model year alone has 128 complaints for power steering failure. GM issued a recall in March 2010, but some owners report the issue recurring even after the recall repair.
Common Symptoms
- Sudden loss of power steering assist
- Steering becomes very heavy without warning
- Power steering warning light illuminated
- Steering effort increases in cold weather
- Intermittent power steering that cuts in and out
How to Fix
Check VIN for recall eligibility. Dealers replace the electric power steering motor free of charge under the recall. If power steering fails while driving, pull over safely - the vehicle can still be steered but requires much more physical effort. Report recurring failures to NHTSA.

Chevrolet SS · 2014–2017
The Chevrolet SS (imported Holden Commodore VF) suffers from electric power steering failure caused by fretting corrosion of the connector between the EPS module and torque sensor. When corrosion degrades the electrical connection, power steering assist is suddenly lost, requiring significant physical effort to steer the vehicle. This is especially dangerous at highway speeds. GM recalled approximately 6,204 vehicles for this issue.
Common Symptoms
- Sudden loss of power steering assist while driving
- Steering becomes extremely heavy with no warning
- Power steering warning light illuminated
- Intermittent power steering assist that cuts in and out
- EPS fault codes stored in steering module
How to Fix
Contact Chevrolet dealer to verify recall eligibility for your VIN. The recall remedy involves replacing the steering gear assembly with a new unit fitted with gold-plated terminals that resist corrosion. This repair is free under the recall. If out of recall coverage, the steering rack replacement costs $1,500-$2,500.

GMC Hummer EV SUV · 2024–2026
The Hummer EV SUV's adaptive air suspension system, which offers up to 16 inches of ground clearance in Extract Mode, can develop calibration errors that prevent the system from reaching full height. The height sensors, air compressor, and air springs must all function in concert. Software bugs can cause the system to display incorrect ride height or refuse to enter Extract Mode. The compressor can also overheat from repeated height adjustment cycles, entering a cooldown period that locks out suspension adjustments.
Common Symptoms
- Extract Mode not reaching full height
- Suspension malfunction warning message
- Vehicle sitting unevenly
- Ride height adjustments not responding
- Compressor cooldown message after multiple height changes
How to Fix
GM has released software updates that improve air suspension calibration accuracy. Visit the dealer for recalibration using the GDS2 diagnostic tool. If the compressor overheats, allow it to cool for 30 minutes before attempting further adjustments. For persistent Extract Mode failures, the height sensors may need recalibration or replacement.

Frequently asked questions
What does C0710 mean?
C0710 stands for "Steering Position Sensor." C0710 is a chassis code indicating a fault with the steering position (steering angle) sensor, which tells stability control and related systems how far and how fast you are turning the wheel. The control module compares this signal to other inputs, and when the steering sensor reading is missing, out of range, or implausible, it sets this code. You may lose stability control, traction control, or electronic steering assist, with corresponding warning lights. It points to the steering angle sensor or its circuit rather than a mechanical steering part.
What are the most common causes of C0710?
The most common causes of C0710 are: Faulty steering angle/position sensor, Steering angle sensor needs calibration after service, Damaged clockspring affecting the sensor circuit, Wiring or connector fault at the sensor, Loss of power or ground to the sensor, Communication fault between the sensor and stability module, Worn steering column components affecting sensor reading. The specific cause varies by vehicle.
How much does it cost to fix C0710?
Repair costs for C0710 range from $400 to $2,500, depending on the vehicle and root cause.
