Rear tracking begins oscillating dangerously in winter driving conditions. Extremely dangerous. Going 30 MPH and being passed by every car on the road while I am fighting to keep from crashing. Rear wheels seem to transfer traction to tires that are slipping, oscillating back and forth, causing rear end to fishtail at any speed. Replaced tires and same thing. This is the scariest thing I…

What stands out
Owners have filed 31 suspension 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.
Among the 13 model years of Subaru Outback in our records for suspension problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: A 2006 Outback carries significant risk on winter roads due to uncontrolled rear-end oscillation at moderate speeds, especially when loaded—a phenomenon owners call "ghostwalking" that has persisted despite alignment adjustments and tire changes. Beyond the handling issue, expect premature strut failures, CV boot problems, and occasional engine/drivetrain wear that can be costly to repair.
The dominant complaint is rear-end instability on icy or snow-packed roads, occurring at 30–50 mph on straight sections. Owners describe uncontrolled side-to-side motion—called "ghostwalking"—where the rear acts like it's steering itself, independent of driver input. The problem worsens dramatically with rear passengers or cargo and forces drivers to crawl well below traffic speed to maintain control. Multiple owners with decades of winter driving experience state they have never encountered this behavior in other vehicles, including older Subarus. Alignment corrections per TSB 05-36-07 and tire replacements do not resolve the issue; dealerships have acknowledged similar complaints from other owners but cannot pinpoint the cause.
Secondary suspension issues include premature rear-strut failure with fluid leaks as early as 17,500 miles, and control-arm bushing and ball-joint deterioration. CV axle boots tear at moderate mileage (55,000–82,000 miles), with one case resulting in an axle fire. One owner experienced multiple engine and turbo failures on a turbocharged model, with the No. 1 piston coming loose across separate incidents. Wheel bearings, head gaskets, and the transmission (hard shift when cold) also show premature wear. Subaru has not recalled the vehicle for the ghostwalking condition and has declined to cover many of these repairs once warranty expires.

Failure modes owners describe
Rear-end ghostwalking and oscillation on ice/snow
Uncontrolled side-to-side rear-end motion on icy or packed-snow roads, occurring spontaneously on straight sections at moderate speeds (typically 30–50 mph). Owners describe it as the rear 'steering itself,' fishtailing, or swaying as if being pushed left and right. The motion is independent of driver input (braking, acceleration, steering) and worsens significantly when the vehicle carries rear passengers or cargo weight.
When: Occurs most frequently between 30–50 mph on icy/snow-packed roads; some owners report it at speeds as low as 20–40 mph with passengers/cargo. Several narratives indicate the problem was present from early ownership (as early as 28,000 miles in one case; another owner encountered it at 40,000+ miles). One owner noted the issue recurred across multiple winters.
Symptoms owners cite: Rear end sways or oscillates side-to-side on straight road sections; Loss of directional control; vehicle acts like it is 'floating' or 'steering itself'; Fishtailing motion; rear wheels seem to lose traction independently; Phenomenon referred to as 'ghostwalking' by multiple owners; Intensifies with rear-seat passengers or cargo weight; Occurs even with dedicated snow tires and proper alignment; Drivers forced to slow to unsafe speeds (often 20–30 mph below surrounding traffic) to maintain control
Repairs/costs cited: Multiple owners report alignment adjustments (per Subaru TSB 05-36-07 or dealer recommendation) have not resolved the issue. Tire replacements and strut replacements also do not address the problem. One dealer technician acknowledged other customers had the same complaint but could not identify a root cause. Subaru technical service bulletin TSB 05-36-07 modified rear toe tolerance, yet owners indicate the issue persists or worsens when load is added, suggesting rear toe-in changes under weight.
Recalls/TSBs owners mention: Subaru Technical Service Bulletin 05-36-07 addresses rear toe alignment tolerance. Dealers have inspected vehicles and stated components are per factory specs. Subaru has not issued a recall for this condition. One dealer recommended more aggressive snow tires as a workaround; owners dispute this addresses the root cause.
Premature rear strut failure and leaking
Rear struts leak or lose dampening ability prematurely, compromising suspension control. One owner reported rear shocks losing dampening ability after extended freeway driving, causing uncontrolled rear bouncing over minor road imperfections and hitting bump stops. Another owner's rear struts leaked at only 17,500 miles (14 months old).
When: Reported at 17,500 miles, ~28,000 miles, and 55,000 miles. One owner noted the issue manifests after 30+ minutes of freeway driving due to overheating.
Symptoms owners cite: Rear shocks leak fluid; Loss of dampening ability after extended highway driving; Uncontrolled bouncing of rear end over minor road dips; Rear suspension compresses and hits bump stops
Repairs/costs cited: Rear struts require replacement. Owners report costs in the range of several hundred dollars per replacement. One owner replaced all four struts in an attempt to resolve oscillation issues (without success in addressing ghostwalking).
Recalls/TSBs owners mention: Subaru has inspected vehicles and stated rear components are per factory specifications. Warranty coverage has been denied in at least one case (17,500 miles) for 'warranty reasons' despite premature failure. No recall identified.
CV axle boot failures (front and rear)
Torn or failed CV boots on both front and rear axles, leading to joint contamination and potential drivetrain failure. One owner experienced multiple CV boot failures across a relatively short window.
When: Reported at approximately 55,000–60,000 miles. Another owner experienced an axle boot failure at 82,000 miles, which resulted in a fire.
Symptoms owners cite: Torn CV boots discovered during routine service inspections; One case involved fire when a torn axle boot failed at 82,000 miles
Repairs/costs cited: CV axle replacement is required. Costs reported by owners range from under $500 (independent shop) to significantly higher at dealerships. One owner was offered a 50% Subaru reimbursement if repairs were performed at an authorized dealership.
Recalls/TSBs owners mention: Subaru declined to cover CV boot repairs or issue a recall despite owner reports indicating the issue is 'quite common in Subarus.' Subaru offered partial reimbursement (50%) in one case if the repair was performed at a dealership.
Engine and turbo failures (3.0L turbocharged model)
Multiple engine and turbo failures on a 2006 Outback 3.0L turbocharged model, with the No. 1 piston coming loose on at least two separate occasions, accompanied by coolant, oil, and other fluid losses, and heavy smoke.
When: First engine failure covered under warranty (mileage not specified). Second engine/turbo failure at 94,591 miles (November 2010). Third engine/turbo failure at 136,000 miles (August 2012). Oil pump failure at 121,115 miles (November 2011). Oil leak at 96,650 miles (November 2010).
Symptoms owners cite: Check engine light illuminated in all three incidents; Coolant, oil, and other fluid loss; Heavy smoke from engine bay; No. 1 piston came loose (confirmed in diagnostic on third failure)
Codes mentioned: Check engine light (all three incidents)
Repairs/costs cited: First engine replacement covered by warranty. Second engine/turbo repair cost $5,005.00 (November 2010), not covered by warranty. Third engine/turbo repair quoted at $9,000+ (August 2012); owner declined due to cost and vehicle was abandoned. Additional repairs: oil pump failure $495.00 (November 2011); oil leak repair $853.87 (November 2010).
Recalls/TSBs owners mention: First engine failure covered by warranty. Subsequent failures deemed out of warranty; no manufacturer assistance documented.
Premature front and rear wheel bearing failures
Right and left rear wheel bearings failed prematurely. One owner also noted that Subaru stated a recall on wheel bearings did not apply to their Outback, even though the failed part was identical to those covered under the recall.
When: Right and left rear wheel bearings failed at 118,072 miles (October 2011). Wheel bearing recall inquiry at ~125,000 miles on another vehicle.
Symptoms owners cite: Wheel bearing noise or failure requiring replacement
Repairs/costs cited: Wheel bearing replacement cost $897.49 for both right and left rear bearings (October 2011).
Recalls/TSBs owners mention: Subaru indicated a wheel bearing recall did not apply to at least one owner's vehicle, despite the failed part being identical to those covered under the recall.
Control arm bushings and ball joint failures
Control arm bushings and ball joints failed prematurely, causing clicking sounds during reversing and requiring replacement. One owner replaced control arms, ball joints, and bushings multiple times with recurrent issues.
When: Failures reported at 96,647 miles. One owner with 40,000 miles reported repetitive ball joint clicking with multiple replacements already performed.
Symptoms owners cite: Ball joints click while reversing; Control arm bushings split or deteriorate
Repairs/costs cited: Front and rear control arm bushings replacement at 96,647 miles cost $482.33. One owner with 40,000 miles reported control arms, ball joints, bushings, and bearings have all been replaced multiple times, suggesting recurrent failures.
Transmission shifting problems
Hard jerking while shifting from 2nd to 3rd gear, particularly when the transmission is cold. Reported on an automatic transmission vehicle.
When: Reported at approximately 40,000 miles; issue is recurrent (occurs every time the transmission is cold).
Symptoms owners cite: Hard jerking during 2nd-to-3rd gear shift when transmission is cold
Brake performance issues
Brake system problems including excessive stopping distance at low speeds and general brake difficulties.
When: Reported at approximately 40,000 miles.
Symptoms owners cite: Takes a long time to stop at slow speeds
Axle boot failure causing fire
A torn or failed axle boot at the front passenger side caused the axle to catch fire while driving at highway speed.
When: Failure occurred at approximately 82,000 miles.
Symptoms owners cite: Toxic odor emitted from outside vehicle; Front passenger-side axle caught on fire while driving
Repairs/costs cited: Owner extinguished the fire. Vehicle was towed to dealer, which diagnosed a failed axle boot.
Recalls/TSBs owners mention: Manufacturer was notified. Vehicle was repaired at dealership.
Front wheel squealing
Intermittent squealing noise from the front left (driver's side) wheel at low speeds, particularly at the start of vehicle operation.
When: Reported on a vehicle with unspecified mileage.
Symptoms owners cite: Front left wheel squeals at low speeds; Noise is intermittent but always present at start of vehicle usage
Repairs/costs cited: Owner has taken vehicle in numerous times; all diagnostics check out OK but noise persists. Possible wheel bearing issue suspected by owner.
Head gasket leaks
Head gasket leaking at high mileage.
When: Reported at 125,000 miles.
Symptoms owners cite: Head gasket leaking
Repairs/costs cited: Repair cost estimated at $2,000.
Recalls/TSBs owners mention: Subaru states replacement gaskets are better than original; however, repair is not covered and owner is responsible for full cost.
Oil pump failure
Oil pump failure resulting in loss of oil circulation.
When: Reported at 121,115 miles.
Symptoms owners cite: Oil pump failure
Repairs/costs cited: Oil pump replacement cost $495.00.

2006 Subaru is unsafe on slippery roads. The car has a tendency to "steer" from the rear. It may be something with the center differential that causes more power to the rear and thus makes the rear want to fishtail out while driving slow in a straight line. It is by far the worst car I have ever driven on ice. Even with snow tires. And I had a RWD cougar with bad tires when I was young. *tr
'06 Subaru outback(auto) seems to have handling issues caused by AWD system. Some have described it as "ghostwalking", where the rear end of the car shifts side to side when the AWD kicks in. Please investigate this problem. Have replaced tires and checked alignment, problem still exists. *tr
