Subaru Outback Common Problems and Repair Costs

Head Gasket Failure (2000–2009, EJ25 Engine)

The 2.5L EJ25 engine used in 2000–2009 Outbacks has a well-documented head gasket problem — a class action lawsuit was filed against Subaru over it. Coolant seeping externally is most common, but internal leakage (coolant mixing with oil) also occurs. Repair cost: $1,400–$2,200. If buying a pre-2010 Outback, ask for cooling system maintenance records and inspect for white exhaust smoke and milky oil.

Excessive Oil Consumption (2013–2017, FB25 Engine)

Subaru settled a class action over oil consumption in 2013–2017 FB25 engines. Affected vehicles can consume 1 quart per 1,000–1,200 miles. Subaru issued a technical service bulletin. Check the oil level every fill-up on affected model years and ask the seller about oil consumption history.

CVT Transmission Issues (2014–2018)

Outback CVT transmissions from 2014–2018 have generated significant complaint volume for shudder, vibration, and premature failure. CVT replacement costs $6,000–$8,000. Subaru extended the CVT warranty to 10 years/100,000 miles on some affected vehicles — verify warranty status by VIN before purchasing. Change CVT fluid at 60,000 miles (Subaru's severe-duty interval is 25,000 miles).

Battery Drain / DCM Module (2017–2019)

The telematics module (DCM) in 2017–2019 Outbacks can cause parasitic battery drain, leading to repeated dead battery situations. Premature battery failure is a known issue. Cost: $200–$400 for battery replacement; some required DCM module replacement or disabling.

What Years to Buy

• Best years: 2020–present (major CVT and oil consumption issues largely addressed)
• Good used value: 2015–2018 if CVT warranty is still active and fluid has been changed
• Avoid: 2000–2009 without documented head gasket repair, 2014–2016 with high CVT mileage and no fluid service records
