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 a vibration analysis worksheet the technician can use in conjunction with the appropriate Vibration Analysis-Road testing procedure when diagnosing vibration concerns.

The failure pattern owners describe
The 2008 Chevy Tahoe hybrid steering system—specifically the electrical power assisted steering (EPAS)—shows a pattern of dangerous failures across 12 complaints. Most critical: complete loss of steering assist without warning or diagnostic codes, happening at speeds from 10 mph to 65 mph. Owners report the steering wheel locking solid, the vehicle refusing to turn despite input, and one incident where the steering reversed direction mid-turn, injuring the driver's hands. One owner documented the wheel suddenly jerking from an 80-degree left turn to a 50-degree right turn in a quarter second.
The root causes cited are power steering module failure and electric motor shaft breakage. One owner's dash camera captured a "Service Power Steering" message appearing only after the failure. Another owner at 90K miles experienced the motor shaft breaking off entirely while traveling 65 mph on the highway. A steering angle sensor fault in another case triggered smoking brakes and loss of assist, but GM no longer supplies the part for 2008 models.
A separate issue: the steering wheel does not return to center after turns—a control module adjustment by the dealer did not fix it. One hybrid owner also reports losing both steering and brake assist when the vehicle's stop-start system shuts down unexpectedly.
Notably, NHTSA recall 14V719000 covers electrical power steering but excludes 2008–2013 hybrids, despite identical systems in other model years. No TSBs have been issued for these vehicles.

Failure modes owners describe
Complete loss of electrical power steering assist
Steering assistance cuts out without warning, leaving the driver without power assist and sometimes locking the steering wheel completely. Occurs during normal driving, highway speeds, and parking maneuvers. Multiple owners report the power steering module failing or the motor shaft breaking internally.
When: Occurs without pattern; reported at 10 mph, 45–50 mph, 60–65 mph, and 90K miles mileage
Symptoms owners cite: Sudden loss of power steering assist mid-drive; Steering wheel locks or becomes immovable; Vehicle continues straight despite steering input; Driver loses steering control in emergency situations; 'Service Power Steering' message appears on driver information center
Codes mentioned: Power steering module failure, Electric power steering motor shaft fracture
Repairs/costs cited: Power steering module replacement required; motor shaft replacement if broken. One owner (122K miles) was quoted a module replacement at dealer but repair not completed due to cost or other factors. Parts availability unclear for 2008–2013 models.
Recalls/TSBs owners mention: No recall issued for 2008–2013 Tahoe hybrids with EPAS (unlike 2015+ models per owner #1). One owner notes VIN not included in NHTSA Campaign 14V719000 (Steering). No TSB found by owners despite electric power steering failures in other GM vehicles.
Steering angle sensor failure
Steering angle sensor stops functioning, triggering dashboard warning lights and linked safety system failures (smoking brakes, loss of steering assist). GM does not manufacture replacement parts for 2008 model year; aftermarket parts do not fit the application.
When: Timing not specified; one owner parked vehicle due to safety concerns
Symptoms owners cite: Multiple dashboard warning lights illuminate; Brakes overheat and smoke; Loss of steering assist when sensor fails
Codes mentioned: Steering angle sensor fault
Repairs/costs cited: Mechanic identified steering angle sensor as root cause. GM no longer manufactures the correct part for 2008 model year. Aftermarket sensors ordered online do not match the required specification. Repair not completed; vehicle parked as unsafe to drive.
Recalls/TSBs owners mention: No parts availability through GM. No recall or service bulletin issued.
Steering wheel does not return to center
Steering wheel remains offset after turning and does not track back to center, a behavior not typical of conventional hydraulic power steering. Dealer adjusted power steering control module settings, but issue persists. Driver must manually straighten the wheel.
When: Ongoing condition during normal driving
Symptoms owners cite: Steering wheel stays offset after slight bumps or full turns; Wheel begins to track back to center but stops short; Manual steering input required to straighten wheel completely
Repairs/costs cited: Power steering control module adjustment performed by dealer; problem unresolved.
Recalls/TSBs owners mention: None; dealer adjustment attempted but did not resolve issue.
Sudden jerking and reversal of steering input
Steering wheel suddenly jerks and reverses direction without driver input during a turn, causing the vehicle to veer toward adjacent traffic. Driver sustained friction burns on palms and sore finger joints from gripping the wheel during the event.
When: Single incident during active left turn
Symptoms owners cite: Steering input reverses from left turn (80–90° angle) to right turn (50–70° angle) in a quarter second; Unintended direction change; 'Service Power Steering' message on DIC after incident; Driver hand injury from sudden wheel movement
Codes mentioned: Power steering module fault (inferred from service message)
Repairs/costs cited: Incident captured on dash camera. No repair status reported.
Recalls/TSBs owners mention: No recall or warranty action mentioned.
Loss of steering and brake assist during stop-start transition
Vehicle shuts off unexpectedly during stop-start automatic transition, resulting in simultaneous loss of both brake and steering assist. Creates a critical safety hazard as driver cannot steer or brake the vehicle after shutdown.
When: Random shutdowns during stop-start transitions
Symptoms owners cite: Unexpected engine shutdown during hybrid stop-start operation; Loss of power steering assist coinciding with shutdown; Loss of brake power coinciding with shutdown; Vehicle cannot be steered or braked during shutdown event
Codes mentioned: Hybrid battery/thermal management fault (inferred from battery SOC, temperature data)
Repairs/costs cited: AUX transmission pump replaced, module updated to latest version, hybrid battery cooling fan replaced. Problem persists. Dealer unable or unwilling to diagnose root cause.
Recalls/TSBs owners mention: None; dealer could not identify issue after multiple component replacements.
Vehicle wanders left and right over bumps
Vehicle steers itself left or right when traversing bumps, unrelated to driver input. Owner attributes issue to 20-inch low-profile aftermarket tires, but problem persists after switching tire brands and models.
When: Ongoing; purchased 2012, tire change attempted 2020
Symptoms owners cite: Vehicle shifts left or right when going over bumps; Bumpy ride quality reported
Repairs/costs cited: Multiple repairs attempted: ball joints replaced (multiple times), wheel hubs, front shocks, steering column U-joint, front-end alignments. Tire brand and model change did not resolve issue.
Recalls/TSBs owners mention: No recall or manufacturer involvement mentioned.
Steering becomes stiff and unresponsive
Steering suddenly becomes very hard and unresponsive to left or right input, nearly causing a crash. Speed-related; occurred at 60 mph.
When: Single incident at 60 mph
Symptoms owners cite: Steering suddenly becomes very stiff; No response to left or right steering input
Repairs/costs cited: No repair details provided.
Recalls/TSBs owners mention: No information provided.
