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.
WHEELS
Subaru of America, Inc. (Subaru) is recalling certain 2025 Forester vehicles equipped with 18" aluminum alloy wheels. The wheels may have been manufactured with an incorrectly specified lug seat surface, which can result in the wheel being improperly attached and cause a loss of vehicle stability.
CHILD SEAT
Subaru of America, Inc. (Subaru) is recalling certain 2025 Forester vehicles. The child seat anchor bolts may have been improperly tightened, allowing the bolts to come loose.
EQUIPMENT:OTHER:LABELS
Subaru of America, Inc. (Subaru) is recalling certain 2026 Crosstrek Hybrid, 2025-2026 Forester Hybrid, Forester, and 2019-2026 Ascent vehicles. These vehicles were manufactured with an incorrect Gross Axle Weight Rating (GAWR) on the certification label. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) 110, "Tire selection and rims."
ENGINE AND ENGINE COOLING
Subaru of America, Inc. (Subaru) is recalling certain 2024 Forester vehicles. The engine water pipe may have loose attachment bolts, allowing the pipe to lose its seal and leak coolant.

The Lineartronic CVT (TR690) in 2014-2021 Foresters can develop shuddering, hesitation, and in severe cases, complete failure. Symptoms typically begin around 60,000-100,000 miles. The CVT chain can stretch, causing slippage and shudder during light acceleration. The torque conve… Repairs typically run $0-$8,000. Severity: high.
Forester owners report the EyeSight pre-collision braking system applying hard braking with no obstacle present, including on open highways and curves, plus erratic lane-keep-assist interventions, all attributed to the windshield-mounted stereo-camera assembly. A class action ove… Severity: high.
The Data Communications Module (DCM) that powers Starlink keeps trying to reach the defunct cellular 3G network and fails to sleep, drawing excess current with the car off and killing the battery, causing repeated dead-battery no-starts even after a new battery is installed. A cl… Severity: high.
On 2019 Foresters with the FB25 boxer engine, the aluminum PCV valve can separate during heating/cooling cycles, allowing valve fragments to enter the engine and cause a sudden loss of power while driving. Subaru recalled roughly 51,613 2019 Crosstrek/Forester/Ascent vehicles und… Severity: high.
Subaru recalled 10,417 US 2019 Forester and Crosstrek vehicles because a connector inside the Electronic Power Steering (EPS) unit was molded with small gaps in the plastic, leaving inadequate isolation between adjacent terminals. Those terminals can short, which shuts down elect… Repairs typically run $0-$0. Severity: high.
Foresters equipped with a Denso low-pressure fuel pump (part-number prefix 42022-) built before mid-2019 use a low-density plastic impeller that absorbs fuel, swells and deforms inside the pump housing. The deformed impeller binds against the housing and abruptly cuts fuel delive… Repairs typically run $0-$1,300. Severity: high.
5th generation Foresters (2019+) have widespread reports of windshield cracks initiating near the EyeSight camera housing area or from the edges with no impact. The windshield design incorporates an acoustic interlayer and EyeSight camera calibration zone that creates stress conc… Repairs typically run $500-$1,500. Severity: medium.
Foresters with the 2.5L FB25 engine experience premature A/C compressor failures, often with a noisy clutch or complete seizure. The compressor clutch bearing fails first, creating a grinding or squealing noise when the A/C is engaged. If not addressed, the compressor can seize a… Repairs typically run $600-$2,200. Severity: medium.
Coil-on-plug ignition coils on the Forester are a common failure point. As the coil's internal epoxy/resin cracks with heat and age, the coil produces erratic or insufficient spark, causing single-cylinder misfires, rough idle, hesitation on acceleration, reduced fuel economy and… Repairs typically run $60-$350. Severity: medium.
Forester moonroofs drain rainwater through small tubes routed down the A/B pillars to discharge under the car. The corner drains clog with pollen, dirt and tree debris, or a tube pops off its nipple at the sunroof gutter. Water then backs up and overflows into the headliner and c… Repairs typically run $0-$350. Severity: medium.
The front CV (constant-velocity) axle boots on Foresters crack and tear with age and from suspension flex and road debris. Once the boot splits, grease slings out and dirt/water get in, so the now-dry CV joint wears and produces a clicking or popping that is loudest during tight,… Repairs typically run $200-$600. Severity: medium.
Foresters commonly throw a P0420 'Catalyst System Efficiency Below Threshold (Bank 1)' code and an illuminated check-engine light. While the converter itself is the part that degrades, the underlying root cause on FB25 Foresters is frequently the well-documented excessive-oil-con… Repairs typically run $200-$2,200. Severity: medium.
The Harman-built Starlink head unit on 5th-gen Foresters freezes on startup, reboots in a loop every few seconds, or goes to a black/blank screen, often after a software update. Subaru issued TSB 15-228-18R covering 2019-2020 Forester (among other models) for display freeze-up or… Severity: medium.
Foresters are prone to early front brake rotor distortion (thickness variation) that produces a pronounced pulsation/judder felt through the steering wheel and brake pedal when braking, often appearing at relatively low mileage. Owners across multiple generations report warped/ju… Repairs typically run $300-$700. Severity: medium.
For 2019 the SK Forester switched the FB25 from port injection to direct injection.

Subaru recalled 2019 Forester (with 2018-2019 Crosstrek and 2019 Crosstrek Hybrid) — over 400,000 US vehicles — because initial variation in rear stabilizer bracket dimensions allowed the rear stabilizer bar bracket bolts to loosen in service and detach. With bolts missing the br… Repairs typically run $0-$0. Severity: medium.
The boxer engine's two valve covers face outward and sit low on each side, exposing the cork/rubber valve cover gaskets and the spark plug tube seals to heat cycling and the path of any leaking oil. As these seals harden and shrink, oil seeps out and visibly drips onto the exhaus… Repairs typically run $250-$700. Severity: medium.
Foresters routinely wear the inner edges of the rear tires bald at low mileage (often 20,000-30,000 miles). The rear suspension allows toe adjustment but not camber, and the factory frequently leaves the rear toe set too aggressively, scrubbing the inner shoulders. Because owners… Repairs typically run $100-$250. Severity: low.
