Reliability report · 2020 Subaru Outback · Updated July 2026

The sixth-gen launch year — six recalls, a turbo CVT campaign, and a new thermal control valve, nearly all covered, so verify the work was done.

2020 is the launch year of the current Outback, and it shows: 890 complaints and six recalls, more than any other year here. The headliners are the turbo cars' CVT chain-slip recall (21V955, expanded by 22V485) and an occupant-detection-system airbag recall (24V227) where a cracked sensor could stop the passenger airbag deploying. It's also the first year of the thermal control valve — a Subaru specialist's stated reason to prefer an '18 or '19 — though Subaru extended that valve's warranty to 15 years/150,000 miles.

The redeeming pattern is that almost every 2020 problem has a free or extended remedy: the CVT recall, the thermal control valve extension, the windshield extension and settlement, the head-unit extension. The cars to avoid are the ones where none of it was done. Drive the transmission, confirm the six recalls by VIN, and check the coverage — this is a Squawking year because of the launch-year stack, not a broken design.

Canary status

Squawking

What that means: 890 federal complaints and six recalls as the redesigned sixth generation launches — including the turbo CVT chain-slip campaign and an occupant-detection airbag recall. This is also the first year with the thermal control valve, a repair a Subaru specialist calls expensive. Almost everything is covered; the redesign-year risk is buying one where the work was skipped.

Turbo CVT chain-slip — recalled, free, but confirm it was done

major
  • 2.4L turbo (FA24)

On the turbo (XT) cars, a Transmission Control Unit programming error could let the clutch engage before the CVT's drive chain was fully clamped, so the chain could slip or break and cause a loss of drive power. Subaru recalled it under 21V955 (Subaru code WRK-21) and expanded it with 22V485 (WRK-22): dealers reprogram the control unit, inspect the chain, and replace the transmission free if slippage is found. The federal file for 2020 is heavy with transmission-slip and loss-of-drive reports, and some owners describe long waits for the repair. On a turbo car, confirm the CVT recall shows completed by VIN — and if a car already had chain slip, make sure the transmission was actually replaced.

Thermal control valve — expensive out of pocket, but covered 15 years/150,000 milesmoderate

The sixth generation introduced a thermal control valve (a coolant-flow valve, part of the thermostat system) that a Subaru specialist singles out as a 'problematic expensive repair' the 2018–2019 cars didn't have — enough that he'd trade a 2020 down to an older car to avoid it. The saving grace: Subaru extended its warranty to 15 years/150,000 miles. The federal file shows thermostat/coolant-valve leaks and check-engine reports. If the coolant system throws a code, this valve is a first suspect — and within that long coverage window the repair should be free. Confirm eligibility by VIN.

Six recalls including occupant-detection airbag and brake-pedal boltmajor

Beyond the CVT campaign, 2020 carries an occupant-detection-system recall (24V227) — a sensor capacitor can crack and short, potentially stopping the front-passenger airbag from deploying; dealers replace the sensors free. Others: a brake-pedal mounting bolt that may be missing or loose, deforming the mount and reducing braking (19V664); an over-the-air update that timed out and could shut off the rearview display (20V766); and the wide Denso fuel-pump recall (21V587). All are free. With six campaigns on one car, verify every one by VIN.

FA24 turbo oil-pan seal leakminor

  • 2.4L turbo (FA24)

An owner of a 2020 turbo (Onyx/Limited/Touring XT, 2.4L FA24) reported an oil-pan-seal / sealant leak specific to that engine. It's a smaller item than the cam-carrier leak on the naturally-aspirated cars, but on a turbo 2020 it's worth checking the oil pan and lower engine for seepage during inspection.

Windshield and Starlink — fragile but coveredminor

The sixth-gen acoustic windshield cracks easily — sometimes from minor impacts or temperature — and replacement runs $500–$1,100 with EyeSight (the camera driver-assist) recalibration added. Subaru extended windshield warranty coverage for 2020–2022 and there was a class-action settlement. The Starlink infotainment head unit can go blank or freeze the rearview camera; Subaru extended head-unit warranty coverage for 2019–2022 and settled an EyeSight class action. Both are annoyances with coverage rather than expensive surprises — confirm any windshield/head-unit work and coverage eligibility.

The 2020 does have the thermal control valve on it, which is a problematic expensive repair, whereas 2018 and 2019 Outbacks did not have it.
