ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM)
Subaru of America, Inc. (Subaru) is recalling certain 2022 Outback vehicles. The engine wiring harness may have been damaged, resulting in a loose electrical connection to the engine control unit (ECU).
VISIBILITY:WINDSHIELD
Subaru of America, Inc. (Subaru) is recalling certain 2022 Impreza and Outback vehicles. The incorrect paint clearcoat may have been applied, which can cause the windshield to be insufficiently bonded to the vehicle. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 212, "Windshield Mounting."
POWER TRAIN:AUTOMATIC TRANSMISSION:PARK/NEUTRAL START INTERLOCK SWITCH
Subaru of America, Inc. is recalling certain model year 2021 Crosstrek, 2022 Forester, 2021-2023 Legacy, and Outback vehicles. An insufficient weld may allow water to enter the inhibitor switch, causing it to fail.
AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION:FRONT PASSENGER
Subaru of America, Inc. (Subaru) is recalling certain 2020-2022 Outback and Legacy vehicles. A capacitor in the sensors for the Occupant Detection System (ODS) may crack and short circuit, which can prevent the front passenger air bag from deploying in a crash.
POWER TRAIN:SHIFT LINKAGE/CABLE/ROD
Subaru of America, Inc. (Subaru) is recalling certain 2021 Outback and Impreza vehicles. The continuously variable transmission (CVT) select lever cable nut may not have been tightened properly, allowing the nut to loosen.

Repair costs for known Subaru Outback issues range from $0 to $4,500, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, Head Gasket Failure, typically costs $1,500-$2,500 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The 2.5L non-turbo engine is known for external head gasket leaks. Oil seeps past the gasket and can contaminate the coolant. Subaru extended warranties and improved gasket design in later years. Repairs typically run $1,500-$2,500. Severity: high.
On 2010-2014 Legacy and Outback models, contamination inside the windshield wiper motor bottom cover can cause internal components to interfere. If an obstruction such as snow or ice prevents the wiper arms from returning to the park position, the motor can overheat: the wipers m… Repairs typically run $0-$150. Severity: high.
Older Outbacks (part of the 2003-2014 Subaru population) are covered by the industry-wide Takata airbag recall for the FRONT PASSENGER airbag inflator. The ammonium-nitrate propellant can degrade after years of exposure to heat, humidity, and temperature cycling, causing the infl… Repairs typically run $0-$0. Severity: high.
Early Lineartronic CVT Outbacks (2010-2015) have documented internal CVT failures — most commonly valve-body faults, but also chain/pulley and pressure-control problems — that can cause harsh or delayed engagement, RPM flare, jerking, limp mode, or complete loss of drive. Subaru… Repairs typically run $0-$4,500. Severity: high.
P0455 indicates a large (gross) EVAP leak — the system can't hold pressure/vacuum at all during the self-test. Across the Subaru lineup (Outback, Forester, Impreza, Crosstrek) the standout pattern is the purge control solenoid valve failing due to internal seal degradation, which… Repairs typically run $30-$700. Severity: medium.
Outbacks with a sunroof/moonroof commonly develop interior water leaks caused by clogged, kinked, or (on some 2020 Touring XT builds) factory-blocked sunroof drain tubes. Rather than draining out, water backs up in the sunroof frame and overflows into the headliner and down the A… Repairs typically run $150-$800. Severity: medium.
Owners across multiple Outback generations report premature wheel hub bearing failure, most commonly showing up between roughly 80,000 and 120,000 miles. The classic symptom is a low-pitched droning/humming or 'beehive' noise that begins around 45-55 mph and gets louder with spee… Repairs typically run $200-$700. Severity: medium.
On the Subaru boxer engine, Bank 2 is the driver's side (cylinders 2 and 4). P0430 sets when the driver-side rear (downstream) O2 sensor tracks the front sensor too closely, telling the ECM the catalytic converter is no longer scrubbing exhaust efficiently. On the Outback this mo… Repairs typically run $250-$2,500. Severity: medium.
P0741 sets when the ECM/TCM commands the torque converter clutch to lock up but the expected reduction in converter slip doesn't happen. On the older automatic-transmission Outbacks (4EAT/5EAT, roughly 2005-2014) the dominant real-world causes are a failed torque-converter-clutch… Repairs typically run $150-$1,500. Severity: medium.
P0011 sets when the Bank 1 (passenger-side) intake camshaft is advanced beyond the ECM's commanded position — the AVCS phaser is stuck advanced or the ECM can't control it. On the Outback this is almost always oil-related: low or dirty engine oil, or the passenger-side intake oil… Repairs typically run $70-$450. Severity: medium.
The factory foam gasket behind the roof-mounted center high-mount stop lamp (CHMSL) on the tailgate deteriorates within a few years, allowing rainwater and car-wash water to seep past the light housing and run down the inside of the rear glass into the cargo area. This is a widel… Repairs typically run $15-$300. Severity: low.
P0442 means the ECM detected a small leak in the sealed evaporative-emissions system during its self-test. On the Outback the three usual culprits, in order, are: (1) the fuel filler cap — its rubber O-ring hardens and cracks with age, or the cap isn't clicked tight, or a non-OEM… Repairs typically run $20-$400. Severity: low.
Owners report the HVAC blower fan suddenly stops working on all or some speeds, leaving no air from the vents for heat or A/C. Common root causes on the Outback are a blown blower fuse, a failed blower motor resistor (manual A/C) or power transistor/output stage (automatic climat… Repairs typically run $150-$500. Severity: low.
