Known problems with the 2023 Subaru Forester

2 of the 5 issues we track for the 2019–2024 generation are documented against the 2023 model year, and 1 carries a recall or service bulletin.

  • Parasitic battery drain

    moderateIn re Subaru Battery Drain Products Liability Litigation, No. 1:20-cv-03095-JHR-MJS (D.N.J.); Taylor, et al. v. Subaru of America, Inc., No. 2:26-cv-4935 (D.N.J.), pending as of 2026

    Owners report the 12V battery draining dead after the car sits for a day or two, often traced to a control module failing to enter its low-power sleep state. A 2015–2020-model settlement (In re Subaru Battery Drain Products Liability Litigation) covers 2019–2020 model-year Foresters; a newer proposed class action (Taylor, et al. v. Subaru of America, Inc., filed May 2026) alleges the same defect persists across 2019–2025 Subaru vehicles broadly and is still working through the courts as of this writing. It is not yet a settled claim for later SK-generation model years.

    Typical cost: $0 (covered under the 2015–2020 settlement for eligible 2019–2020 VINs) to $300 for a battery swap that often doesn't fix the underlying drain on later model years

  • Starlink infotainment glitches and backup camera delay

    minor

    The 11.6-in (or 6.5/8-in on base trims) touchscreen occasionally freezes, reboots, or shows a delayed backup camera feed. Software updates resolve most cases; persistent issues need a head unit reflash or replacement at the dealer.

    Typical cost: $0 (software update) to $1,500+ (head unit replacement)

3 more issues reported in other 2019–2024 years

About the Subaru Forester

The Subaru Forester is a compact, boxy crossover that has built its reputation on tall greenhouse visibility, class-leading ground clearance, and standard symmetrical AWD rather than outright power or luxury, which is why "Forester years to avoid" is one of the most-searched Subaru questions online. 5XT turbo held onto the EJ25 turbo (224 hp) paired to a conventional 4-speed automatic, not a CVT. 0XT trim only, now CVT-equipped) and is remembered for turbo oil-starvation from a clogged banjo-bolt oil-feed filter, a 2015–2018 passenger-airbag sensor recall, and the tail end of an FB25 oil-consumption class-action settlement.

The SK generation (2019–2024) rode on the Subaru Global Platform with a direct-injected FB25D (182 hp, no turbo offered in the US) and introduced the Wilderness off-road trim in 2022; it's dogged by a well-documented Thermo Control Valve (TCV) failure that Subaru extended warranty coverage on to 15 years/150,000 miles, plus windshield-cracking and parasitic-battery-drain class actions shared across the Subaru lineup. The redesigned SL generation (2025+) keeps the FB25D (180 hp) and adds Subaru's first factory Forester Hybrid (194 hp combined, e-CVT), with EyeSight driver assist standard fleet-wide. Across every generation, maintenance follows Subaru's familiar pattern: 6,000-mile/6-month synthetic oil changes, an 11-year/137,500-mile first coolant service, a Group 35 battery, 89 ft-lb lug torque, and a CVT on nearly every trim whose long-term health is the single biggest driver of Forester resale value.
