Used Subaru Outback:
what to buy and what to skip

The Outback occupies a niche almost nobody else competes in: a wagon with 8.7 inches of ground clearance, standard all-wheel drive, and the ability to carry a dog, a bike and a family without becoming a truck. It's the default vehicle in mountain states for good reason. The engineering trade-off is Subaru's boxer engine, which has produced two distinct and well-documented problems across different eras.

Best years to buy

Generations where the known problems were already fixed and the price hasn't caught up yet.

2015–2019

Fifth-generation cars. The FB25 engine's oil consumption issues were resolved, EyeSight became widely available, and the CVT proved durable. The best used Outback.

2020–2023

Sixth generation. More refined and better equipped, with the option of the 2.4-litre turbo for people who found the base engine slow. Prices are still high.

Years to avoid

Not "these are bad cars" — these are specific years with a specific, documented failure that costs real money.

2000–2009

EJ25 head gasket era. The gaskets fail between the coolant and oil passages and the repair is $1,500–2,500 on a car that may be worth less than that.

2010–2014

The FB25's excessive oil consumption years. Subaru settled a class action and extended coverage; that coverage has now expired.

Common Subaru Outback problems

The failures that actually show up, and roughly what each one costs to put right.

01 Head gasket failure (1996–2011, EJ25 engines)

The signature Subaru problem. External coolant seepage or internal mixing between oil and coolant. Because the engine is a horizontally opposed boxer, the repair is labour-intensive: $1,500–2,500. Many older Outbacks have had this done already — that's a positive, not a negative, if there's a receipt.

02 Excessive oil consumption (2010–2014 FB25)

A quart per 1,000–1,200 miles. Subaru's class-action settlement covered piston ring replacement for a period that has now closed. Check the dipstick and ask about top-up frequency.

03 CVT failure on early Lineartronic cars (2010–2014)

Shudder, slipping, or a rattle on acceleration. Subaru extended the CVT warranty to 10 years / 100,000 miles on affected cars; most are now outside it. A replacement is $4,000–6,000.

04 Wheel bearings and rear differential bushings

Common wear items on higher-mileage AWD Subarus. Humming that changes with steering input is the tell. $400–700 per corner.

What a used Subaru Outback costs in 2026

Private-party asking prices for average-mileage, clean-title cars. Dealer retail runs roughly 15–25% higher.

Years	Typical price	What you're getting
2005–2009	$4,000–8,500	Assume the head gaskets are either done or due. Manual transmission cars avoid the CVT question entirely.
2010–2014	$7,500–14,000	Check oil consumption and CVT behaviour carefully. Priced attractively for the capability.
2015–2019	$14,000–25,000	The best value in the range. 3.6R six-cylinder cars avoid the four's history and are surprisingly cheap.
2020–2024	$24,000–38,000	Wilderness and XT turbo trims sit at the top.

What to check before you buy

Model-specific. Bring this list to the test drive.

Look at the front and rear of the engine where the heads meet the block for crusty coolant residue — that's a weeping head gasket.
Check the coolant overflow bottle for oil sheen and the oil filler cap for a milky deposit.
Pull the dipstick on any 2010–2014 car and ask how often oil gets added between services.
Accelerate gently from 20 to 45 mph and feel for CVT shudder.
Drive at 45–55 mph and gently weave — a hum that changes as the car loads left and right is a wheel bearing.

Subaru Outback questions

Do all Subaru Outbacks have head gasket problems?

No — the problem is specific to the EJ25 engine used through roughly 2011. The FB-series engines that replaced it don't share the defect, though early FB25s had their own oil consumption issue. Anything from 2015 onward is clear of both.

What are the best years for a used Subaru Outback?

2015–2019 is the sweet spot — past both the head gasket era and the oil consumption years, with a proven CVT and available EyeSight safety systems. 2020–2023 is better still if the budget stretches.

Is the Outback CVT reliable?

The early Lineartronic units from 2010–2014 had real failure rates and Subaru extended their warranty in response. The units from 2015 onward have proven durable. Change the fluid around 60,000 miles regardless of what the maintenance schedule says — it's cheap insurance on a $5,000 component.

Outback or Forester?

The Forester is taller, easier to see out of, and slightly better in tight spaces. The Outback rides better, is quieter on the highway, and has more cargo length. Mechanically they share almost everything, so the decision is about shape rather than engineering.
