What stands out
Steering accounts for 39% of every owner complaint on file for this vehicle — the dominant problem area across 12 categories tracked.
Owners have filed 417 steering complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
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 service bulletin provides technicians with updated information to help identify the differences between what is considered a fluid leak, and what is considered fluid seepage.

The failure pattern owners describe
The 2008 Pontiac G6's steering system shows a pattern of failures centered on the electric power steering motor, torque/position sensor, intermediate shaft, and steering column. Owners report the power steering warning light appearing on the instrument cluster, followed by sudden stiffness or complete loss of power assist at highway speeds, forcing manual steering with significantly increased effort. Some owners describe the steering wheel shaking, jerking, or moving involuntarily while driving or stopped at idle. A clicking, clunking, or popping noise occurs during turns, particularly low-speed turns and cold weather, with some owners reporting the noise recurs within weeks or months of repair. Several owners note the problem appears after battery depletion or resets itself when the vehicle is turned off and restarted. Multiple owners mention being told by dealers they cannot duplicate the problem or that the VIN does not qualify for available recalls despite matching symptoms. Repair attempts include replacement of the torque sensor, power steering motor, intermediate shaft (sometimes replaced multiple times), steering column, and rack-and-pinion assembly. Some owners report the same failure recurring after these repairs, occasionally within days. Two owners describe loss of steering control leading to near-misses or crashes. One owner reported a power steering line break with oil leak and fire hazard warning from the dealership.

Failure modes owners describe
Power steering loss/assist failure
Electronic power steering system loses assist intermittently or completely, requiring manual steering with greatly increased effort. Fails at speed or during turns. Often resets when vehicle is turned off and restarted.
When: Various speeds and driving conditions; some owners report recurring patterns every 30 minutes of driving or at specific speeds around 68 mph
Symptoms owners cite: Power steering warning light and chime on instrument cluster; Steering wheel becomes very hard to turn; Loss of power assist at highway speeds; Steering wheel locks or becomes rigid; Problem recurs intermittently, sometimes multiple times per drive; Manual steering required with excessive force
Codes mentioned: P/S message on DIC, C0545-00 Steering Wheel Torque Input Sensor code
Repairs/costs cited: Torque/position sensor replaced ($400–$1,000); power steering motor and control module replaced; entire power steering column replaced ($685–$1,400); rack-and-pinion replaced. Multiple owners report parts failing again within days to months of replacement.
Recalls/TSBs owners mention: Recalls issued (GM TSB 15-356, NHTSA 14V153000, 10183); Special Coverage Adjustment issued for 10 years/150,000 miles from original in-service date. Dealerships deny coverage when VIN not listed or vehicle exceeds mileage/age limits. Owners report GM refusing to cover torque sensor replacement as part of recall.
Steering wheel shaking, jerking, or involuntary movement
Steering wheel shakes rapidly back and forth or jerks left and right, sometimes violently, while driving at various speeds or while idling. Wheel may move on its own to counter the driver's input.
When: While driving at any speed, while idling at lights/intersections, while stationary in park. Some owners report it happens more frequently after weeks of ownership.
Symptoms owners cite: Rapid back-and-forth shaking of steering wheel; Steering wheel jerks or twitches left and right; Steering wheel attempts to turn itself against driver input; Involuntary lane changes if driver does not hold wheel firmly; Very difficult to keep vehicle straight; Hard to control, especially noted by smaller drivers
Codes mentioned: Power steering warning message
Repairs/costs cited: Torque sensor replaced; intermediate shaft replaced; steering column replaced. Owners report problem recurring after repairs.
Recalls/TSBs owners mention: Recalls available but many VINs reported as not matching recall criteria. Extended warranty (10 years/150,000 miles) referenced but owners denied coverage due to VIN exclusion or mileage/age limits.
Intermediate shaft clunking, popping, or grinding
Loud clunking, popping, or grinding noise from the steering column or intermediate shaft area when turning or moving the steering wheel. Noise often worsens over time.
When: When turning steering wheel left or right; during low-speed turns; sometimes worse in cold weather. One owner reports noise started within weeks after ownership.
Symptoms owners cite: Loud clunking noise during turns; Popping sound from steering column; Grinding or squealing noise; Ratcheting effect felt in steering when turning; Steering wheel tightening and looseness alternately; Noise increases over time
Repairs/costs cited: Intermediate shaft lubricated (temporary fix); intermediate shaft replaced (often with second-generation TSB part); steering rack replaced; torque sensor replaced. One owner paid $416 for intermediate shaft replacement; another replaced rack-and-pinion three times for the same clicking/popping sound without resolution.
Recalls/TSBs owners mention: Technical Service Bulletin issued for intermediate shaft replacement; no recall. One owner told by dealership that GM designed a fix for Arcadia but will not apply it to G6 because the vehicle is no longer in production.
Steering stiffness and resistance (tight steering)
Steering wheel becomes difficult to turn, requiring excessive force. Left-right turning asymmetry reported: one direction very loose, opposite direction very tight and hard to turn.
When: Some owners report issue started early (5,000 miles onward); others report intermittent stiffness during driving
Symptoms owners cite: Steering wheel very hard to turn; Excessive force required to steer; Left turns loose, right turns very tight (or vice versa); Steering feels sluggish and unresponsive; Binding sensation in steering
Repairs/costs cited: Intermediate shaft replaced; torque sensor replaced; steering column replaced. Dealers have told some owners this is normal operation for electronic power steering.
Recalls/TSBs owners mention: One owner reports dealer claimed this is normal electronic power steering behavior.
Steering wheel whining, squealing, or grinding noise
High-pitched whining or squealing noise from the steering system that increases in volume over time. Occurs when steering wheel is moved. Described as piercing and concerning.
When: Initially only during left or right turns; later with any steering wheel movement; one owner noted sound began a year prior and has become louder
Symptoms owners cite: Loud piercing whining noise; Squealing or rubber-like sound; Noise indicates something may snap; Noise worse than year prior; Concerns driver that part will fail under use
Repairs/costs cited: Power steering pump replaced (did not fix issue); one owner told dealership stated GM has same problem on Arcadias but fixed it there, refusing to fix G6.
Recalls/TSBs owners mention: Dealership refused repair, citing that G6 production has ended and no redesigned part is available for retrofit.
Steering motor failure (electric assist)
Electric power steering motor fails, resulting in complete loss of power steering assist. Motor may fail early in vehicle life.
When: One owner reported failure at 15,000 miles; another early in ownership
Symptoms owners cite: No power steering at all; Power steering warning message; DTC code generated
Codes mentioned: Power steering DTC
Repairs/costs cited: Motor and control module replaced by dealership.
Recalls/TSBs owners mention: Dealership covered replacement under warranty at point of sale.
