What stands out
Owners have filed 33 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.
No new NHTSA steering complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
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 procedure to flush and bleed power steering system to correct a power steering noise or fluid leak concern that is caused during extremely low temperatures.

The failure pattern owners describe
The 2015 GMC Acadia has pervasive steering system problems that begin early in the vehicle's life. Power steering pump failure is the dominant issue—occurring between 31,000 and 69,000 miles—with owners hearing loud whining or grinding and finding either intermittent assist loss or complete failure at low speeds (parking lots, turns). Many pumps leak visibly; one owner found metal shavings in the fluid. Repair costs run $900–$1,500, and parts often sit on backorder at dealers because the failure is so common.
Owners report GM is aware of these complaints but has not recalled the 2015 model, despite issuing recalls for the same pump failure on earlier model years (2007–2011). Warranty coverage excludes the pump—even under powertrain protection—leaving owners to pay out of pocket.
More alarming are incidents of steering lockup or complete loss of power assist without warning, including at highway speeds (60–70 mph). One owner hit a concrete barrier when the steering locked; another lost control and drifted to the shoulder. Some vehicles exhibit intermittent simultaneous failures of steering, braking, and engine power, with dashboard warnings (Service Stabilitrak, Service Traction Control, engine power reduced) that appear and disappear. One owner reported the same failures occurred in a brand-new rental GMC after only 600 miles. Dealers struggle to diagnose these compound failures; parts replacements (transmission, sensors, engine mounts) have not reliably corrected them.

Failure modes owners describe
Power Steering Pump Failure & Leakage
Power steering pump leaks (often moderate to severe) and fails internally, sometimes with metal shavings detected in fluid. Failures occur across a wide mileage range (31k–69k miles) and result in stiff steering at low speeds, intermittent loss of assist, or complete loss of power steering. Metal grinding and high-pitched whining accompany the failure in many cases.
When: 31,000 to 69,000 miles; some owners first notice symptoms 6 months after purchase or within 3–4 years of ownership
Symptoms owners cite: Steering wheel becomes very stiff or hard to turn, especially at low speeds and when parking; Loud whining or grinding noise when turning; Complete or intermittent loss of power steering assist; Power steering fluid leaks visible on driveway or under vehicle; Metal shavings found in power steering fluid; Difficulty turning wheel without excessive force
Repairs/costs cited: Pump replacement typically costs $900–$1,500; some owners also report needing pressure hose replacement or fluid flush (~$2,000 combined for multiple repairs). Parts often on backorder per dealers.
Recalls/TSBs owners mention: GM aware of similar reports but no recall issued for 2015 Acadia model. Pump typically not covered under powertrain warranty; extended warranties also exclude this repair. GM advised one owner they are aware of several similar complaints but offered no recall or warranty coverage.
Rack & Pinion Steering Failure
Steering rack and pinion assembly fails prematurely, with at least one owner reporting two failures within 3 years on a $45,000+ vehicle. No warning lights precede failure. Owner reports rack-and-pinion is classified outside powertrain warranty despite being a steering component.
When: Just under 1 year old (first failure), then again just over 3 years old (second failure)
Symptoms owners cite: Loss of steering control or feel; Potential catastrophic steering failure with no warning
Repairs/costs cited: Replaced under warranty on first occurrence; second replacement (at 3+ years) not covered and cost owner significant repair expense.
Recalls/TSBs owners mention: First failure covered under warranty; second failure and ongoing issues not covered despite rack-and-pinion being a steering component. Owner states repair is not covered under powertrain warranty.
Steering Lockup & Loss of Control at Highway Speed
Steering wheel locks up suddenly or power steering fails completely while driving at highway speed (60–70 mph), creating severe safety hazard. In one documented case, officer could not turn steering wheel after incident. Power assist comes and goes intermittently; steering becomes difficult to operate.
When: During highway driving; one incident documented on September 4, 2018
Symptoms owners cite: Steering wheel locks up without warning; Complete loss of power steering assist at speed; Steering becomes intermittently soft and then difficult; No warning lights illuminate before failure; Vehicle difficult or impossible to maneuver to avoid obstacles
Repairs/costs cited: One incident resulted in collision with concrete barrier; repair estimate indicated power steering issue but specific repair cost not stated.
Multiple Steering & Drive Control System Failures (Intermittent Electrical/Sensor Issue)
Vehicle exhibits a pattern of multiple simultaneous failures—loss of steering, braking, traction control, and engine power—occurring intermittently (5–7 starts) and sometimes unpredictably. Service Stabilitrak, Service Traction Control, and engine power reduction warnings appear. One owner reports same issue occurred in a brand-new rental GMC (600 miles). Dealer diagnosed failed transmission, steering column block pump sensor, and broken engine mount (parts on backorder).
When: Intermittent; repeating every 5–7 vehicle starts in one case; occurs at highway speed, at traffic lights, and while parked
Symptoms owners cite: Complete loss of steering control; Loss of engine power (vehicle slows from 70 mph to 25 mph); Vehicle shakes violently; Traction control would not engage; ABS light illuminates; Check engine light illuminates; Message 'Decreasing Power to Engine' appears; Transmission feels jerky and jumps gears; All dashboard lights illuminate simultaneously
Codes mentioned: Service Stabilitrak warning, Service Traction Control warning, Engine Power Reduced message
Repairs/costs cited: Dealer replaced failed transmission, steering column block pump sensor; broken engine mount diagnosed (noted as on backorder due to frequency of failure). Specific repair costs not itemized but owner faced multiple service visits.
Recalls/TSBs owners mention: Dealer initially non-diagnostic ('turn it off and on again'); later replaced components but issue persisted. Issue also appeared in brand-new rental GMC, suggesting systemic problem.
Intermittent Complete Loss of Steering, Braking & Electrical Function
Vehicle loses steering, electrical systems, and braking power simultaneously and intermittently, usually at intersections or low speeds but sometimes on highway. Put vehicle in park and open driver's door restores function. Power assist may work again immediately after reset. Park assist sensor sometimes goes off erratically before failure.
When: Intermittent; at city intersections during slow speeds, at traffic lights, and once on highway during acceleration; one highway incident during construction zone slowdown
Symptoms owners cite: Complete loss of steering, electrical, and braking control; Park assist sensor goes off erratically before failure (not always); Message to roll down driver's side window then back up; Engine power reduction (limp mode) when accelerating on highway
Steering Wheel Shake When Braking & Steering Noise
Steering wheel shakes when brake is applied. Power steering makes loud noise from steering rack box. Symptom worsens over time; noise becomes louder. No warning lights or diagnostic code triggers.
When: Progressive worsening over time; no specific mileage reported
Symptoms owners cite: Steering wheel shakes during braking; Loud noise from steering rack box when turning wheel; Noise increases in volume over time

What owners are reporting 2 most recent
My first incident on my 2015 GMC acadia sle FWD purchased brand new was this year at 40000 miles. One head light went out and then the other in which the dealer wanted 400+ bucks to replace. The lighting is actually bad from the headlamps. They lights do not extended in front of you to see if you will be coming upon anything and can possibly run it over. My second issue at 41000 was the power…
I noticed the other day when I was turning my steering wheel it was very hard. No light or warring at all. I checked my power steering fluid and it was full. I'm not able to turn the wheels when I'm not pressing on the gas peddle. I want to my local mechanic and he told me that there should be a recall on these cars. Because he has replaced too many in the 2015 model. If I have them replace…
