Subaru SUV Hub — Forester, Crosstrek & Outback

The Forester, Crosstrek, and Outback are the three cars that keep Subaru profitable, and they're also the three cars owners have the most trouble telling apart when shopping. All three run the same boxer engine (FB25 on the current Forester and Outback, FB20 on the Crosstrek), the same Lineartronic CVT (with the option of a 5MT on the Crosstrek), and the same Active Torque Split AWD. What separates them is size, ride height, and the specific set of problems each one has aged into.

The Crosstrek is the small one. It's an Impreza on stilts — same 105-inch wheelbase, same 152hp FB20, same Active Torque Split AWD — with 8.7 inches of ground clearance and cladding. Its reliability story is basically the Impreza's: the FB20 has a milder oil-consumption pattern than the FB25, the CVT wants the same 30k-mile fluid service, and the failures owners see most are wheel bearings past 90k and Starlink infotainment freezes. Our Crosstrek problem pages cover both.

The Forester is the medium one and the reliability workhorse of the lineup. The current SK-chassis Forester with the FB25 is one of the highest-owner-satisfaction Subarus in current production, especially post-2019 when the piston-ring update landed. Pre-2019 FB25 Foresters have the oil-consumption story; post-2019 mostly don't. The windshield-cracking issue that showed up on 2019+ Foresters is the current active complaint — it's a manufacturing defect Subaru has been slow to acknowledge, and our Forester problems hub tracks the class-action status.

The Outback is the big one and the most complicated reliability story. The BR-chassis (2010–2014) is the last of the EJ25 SOHC Outbacks and the head-gasket generation — cheap to buy, expensive to keep. The BS-chassis (2015–2019) moved to the FB25 and its own oil-consumption pattern. The BT-chassis (2020+) added the turbocharged FA24 as an option, which brought a whole new failure list to a car that used to be defined by simplicity. The generation-by-generation buying guide is essential on this one — an Outback badge covers three very different cars.

All three share the same transmission and AWD failure modes: CVT shudder from missed fluid changes, wheel-bearing rumble past 90k, and the electronic transfer clutch (ATS) that shudders on tight turns when it's on the way out. The drivetrain guide covers those; the model hubs cover the model-specific stuff.

If you're shopping and can't decide, our compare-the-three page and the individual model hubs are the fastest way to narrow down. If you already own one and something is wrong, use the model hub for your car — every documented problem is tagged there with severity and repair cost.

The cross-shopping question owners ask most often is Forester vs Outback vs Crosstrek at similar model years and price points. The honest answer depends on cargo, ride height, and highway manners. The Forester wins on interior packaging — it has more usable headroom and cargo width than the Outback despite being physically smaller — but loses on highway comfort and NVH past 70 mph. The Outback wins on ride quality and long-trip stability, especially with the FA24 turbo, but its lower roofline makes rear-seat access awkward for tall passengers. The Crosstrek wins on price, city maneuverability, and fuel economy, but its 152 hp FB20 is noticeably slower merging than either of its bigger siblings.

Long-term ownership costs skew slightly toward the Forester across all three generations we've priced. The FB25 in a naturally-aspirated Forester is the cheapest Subaru drivetrain to maintain past 100,000 miles by a meaningful margin — no timing belt, no turbo replacement, no head-gasket generation to worry about (post-2013), and CVT service that's straightforward at any Subaru indy. The Outback with the FA24 turbo carries a modest cost premium mostly attributable to the turbo, coolant lines, and PCV service. The Crosstrek is cheapest to feed and insure but replaces tires and wheel bearings more often than either bigger sibling because of the 8.7-inch ride height and the harder cornering loads on the lightweight subframe.

The safety-tech story is the same across all three — every current-generation Forester, Crosstrek, and Outback ships with EyeSight standard, and the system's real-world performance in IIHS testing is genuinely class-leading. Where the three diverge is on the ADAS features that build on top of EyeSight: adaptive cruise, lane centering, and reverse automatic braking all vary by trim and model year in ways that matter for buyers shopping used. Every model hub below lists the exact package name and year each feature became standard.
