Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering steering on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This informational bulletin explains Unscheduled Supplemental Services and the importance of GM Simplified Maintenance Schedules.

The failure pattern owners describe
Owners of 2010 GMC Terrains describe a pattern of steering and electrical system problems. Power steering loss or stiffening happens abruptly while driving—one owner nearly hit a wall and pedestrian in a parking garage when steering locked. Another owner reports steering friction during long highway drives per GM's Special Coverage Adjustment #14232A, but GM will not replace the steering gear until the condition fully manifests.
Intermittent warning light clusters appear without stored diagnostic codes: service power steering, StabiliTrak, ABS, brake service, and all-wheel-drive service lights all illuminate together, sometimes clearing on their own and sometimes requiring a restart. Dealerships report "miscommunication" with no fault codes to diagnose.
Engine stalling at stops or during city driving is reported multiple times across the narrative set, paired with check engine lights and reduced engine power warnings. One owner cites this as a known safety issue for the model year.
Additional complaints include sudden loss of throttle response on the freeway (engine decelerated from 46 mph to 5 mph without warning; throttle body replacement cost $540 out-of-warranty), severe shuddering during turns and U-turns, and a broken sway bar link discovered during tire rotation. Owner satisfaction with warranty claims and manufacturer responsiveness is low; GM has required extended documentation periods and evidence of failure before honoring coverage.

Failure modes owners describe
Power Steering Loss / Stiffness / Locking
Multiple owners report sudden loss of power steering while driving, steering wheel becoming stiff or locked, or service power steering warning lights appearing. In one case, power steering locked twice—the second time nearly causing a collision in a parking garage. Another owner reports increased friction in the steering system during long highway drives per Special Coverage Adjustment #14232A, with risk of steering wheel sticking in straight-ahead position. One owner reports steering became tight after engine replacement.
When: While driving on highways and city streets; one incident during parking garage entry
Symptoms owners cite: Loss of power steering while driving; Steering wheel stiffens or locks; Service power steering warning light; Increased friction in steering system on straight highways; Steering wheel sticks in straight-ahead position
Codes mentioned: Service Power Steering light
Repairs/costs cited: One owner reports dealership attributed a power steering lock to improper battery cable connection (adjusted, but issue recurred within one month). Another owner needed power steering pump and rack replacement at 140,000 miles. Per SCA #14232A, GM requires the condition to occur before replacing steering gear.
Recalls/TSBs owners mention: SCA #14232A (Power Steering) — GM will only replace steering gear after condition manifests; owner states GM would not provide clarity on whether issue worsens progressively or fails without warning. Dealership repair for battery cable connection on another vehicle.
Service Power Steering Warning Light with Electrical Issues
Owners report service power steering warning light appearing in conjunction with multiple other warning lights (stability control, ABS, brake service, all-wheel-drive service) and electrical system failures. Warning lights sometimes clear on their own; other times vehicle must be shut off and restarted. Dealership diagnostics show no stored codes, attributed to 'miscommunication.'
When: Intermittently during driving on city streets and highways; recurs multiple times over 2–3 weeks
Symptoms owners cite: Service power steering light illuminates; Multiple warning lights appear simultaneously (StabiliTrak, ABS, brake service, all-wheel-drive service); Temporary loss of power steering function; Sluggish acceleration; Lights clear without turning off vehicle or persist until vehicle is shut down
Codes mentioned: StabiliTrak service light, ABS light, Brake service light, All-wheel-drive service light, Service power steering light, No stored diagnostic codes at dealership
Repairs/costs cited: Dealership reports 'miscommunication' with no recorded codes; unable to diagnose intermittent issue.
Engine Stall at Stop / Reduced Engine Power
Vehicle stalls at complete stop or during city driving without warning. Stalling accompanied by check engine light, reduced engine power warning, and service StabiliTrak light. In one case, vehicle stalled twice at stops; in another, rough idle preceded stall. Owner cites this as known safety issue for 2010 Terrain model.
When: At stops and while driving on city streets
Symptoms owners cite: Vehicle stalls at complete stop; Vehicle stalls while driving on city street; Rough idle followed by stall; Check engine light; Reduced engine power warning; Service StabiliTrak light

What owners are reporting 2 most recent
GMC special coverage adjustment #14159a took an unnecessarily long time to fix(over 6 months) because gm said the vehicle has to consume a certain amount of oil every 1000 miles for them to honor the vehicle. I was forced into driving the vehicle less to avoid causing further damage. The longer duration I drove it the more oil it would consume. Why would I keep driving a vehicle if the problem…
My car is idling when it suddenly begins to idle roughly then stalls. There is a "reduced engine power" warning that appears with the check engine light, and "service stabilitrak" with the stabilitrak light. This has happened 3 times, twice when the vehicle was stationary, another time in motion, driving on a city street, and I was able to pull over before it died. In reading other complaints,…
