2021 Subaru Outback Extended Warranty: What 2021 Owners Need to Know
The 2021 Subaru Outback — second year of the sixth-generation Outback (BT), powered by a 2.5L FB25 flat-four on base trims or a turbocharged 2.4L FA24 flat-four on XT trims — factory bumper-to-bumper expired in 2024 for most owners; CVT and infotainment failures are the dominant out-of-pocket concerns — is now at typical current mileage of 47,000–66,000 miles. 2021 Subaru Outback owners are in or approaching the window where major mechanical repairs become statistically likely. Understanding the known failure patterns and warranty coverage status is critical before an expensive breakdown occurs.
Quick Answer
The 2021 Subaru Outback's primary risk is CVT Transmission Failure ($4,000–$6,500). The factory 3-year/36,000-mile bumper-to-bumper warranty expired in 2024.

2021 Subaru Outback: Model Year Overview
The 2021 Subaru Outback — second year of the sixth-generation Outback (BT), powered by a 2.5L FB25 flat-four on base trims or a turbocharged 2.4L FA24 flat-four on XT trims — factory bumper-to-bumper expired in 2024 for most owners; CVT and infotainment failures are the dominant out-of-pocket concerns. By 2026, with approximately 47,000–66,000 miles, this vehicle has moved into the window where deferred maintenance and accumulated wear generate significant repair bills — especially on the CVT and infotainment system, which are the most expensive components to address.
Known Issues on the 2021 Subaru Outback
CVT Transmission Failure
CVT Transmission Failure is the most expensive and widely reported failure on the 2021 Subaru Outback. Owners report costs of $4,000–$6,500 for this repair. By the time noticeable symptoms appear, damage is often already extensive — making proactive coverage the most cost-effective approach.
NHTSA opened Safety Recall Campaign 22V485000 covering 2020–2021 Subaru Outback and Legacy models for CVT chain guide breakage, which can result in a loss of drive power. Beyond the recalled population, Subaru's Lineartronic CVT has also drawn owner complaints and dealer technical service bulletins for shudder and hesitation as vehicles age past 60,000–80,000 miles. Subaru resolved the earlier EJ-series head gasket issue when it moved to the FB/FA engine family starting in 2011, so CVT service — not head gasket repair — is the primary driver of the largest 2021 Outback repair bills, with replacement typically running $4,000–$6,500.
Infotainment / Starlink System Failure
Infotainment / Starlink System Failure is the second most commonly reported concern for 2021 Subaru Outback owners. Repair costs typically run $600–$1,400. While less catastrophic than a CVT failure, these repairs accumulate and are not covered by standard auto insurance.
Wheel Bearing Wear
Wheel Bearing Wear is more common on Outbacks than on many competitors, and repair costs run $400–$800 per corner. It is a lower-severity but recurring cost that owners should budget for as mileage accumulates.
