The Legacy provides a super-comfortable ride that outshines some luxury cars. Handling is responsive but not sporty. This AWD sedan is fitted with a choice of two four-cylinder engines: a 182-hp, 2.5-liter and a 260-hp, turbocharged 2.4-liter.

The Legacy has good fuel economy for an all-wheel-drive car, though its base engine can feel overwhelmed when accelerating. Overall, the Legacy just isn't as good as its rivals, and its below-average predicted reliability rating makes recommending this Subaru even more difficult.

While all mechanical features remain the same, the 2.5i Premium level adds new safety features. Drivers can choose to include EyeSight® driver assist technology,2 which is available in all trims going forward. EyeSight® includes smart features like Adaptive Cruise Control and Pre-Collision Braking.

Generally speaking, a Subaru 2.5 engine has the ability to run between 250,000 and 300,000 miles before needing any kind of significant auto maintenance or repair. Since most drivers average around 14,000 miles per year, this would mean that a Subaru 2.5 engine could conceivably run for over two decades.

The naturally aspirated version - standard in the 2.5i - is much less spirited, at 170 horsepower and 170 pound-feet of torque. We drove a 2.5i allied with Subaru's new Lineartronic CVT automatic - it adds $1000 - and hit 60 mph in 8.8 seconds.

Reliability 8/10 – There are no serious issues on the 2017 Subaru Legacy. Avoid models from 2013–2015 which have some engine problems, while 2016–2022 are more reliable. Performance 7/10 – Performance is okay from both the four-cylinder and V6, although it's not as fun to drive as some competitors.

A common Subaru Legacy problem comes from the CVT transmission in several older models. Owners have shared issues, including reports of the car rumbling and stalling while driving as well as suddenly stopping. There have also been reports of a “growling noise” coming from the engine upon acceleration.

Custom-tailored performance All Subaru Forester models from 2019 onwards feature with one of two different versions of the SI-DRIVE®, each with two different modes. The Forester Sport benefits from having Intelligent (I) and Sport Sharp (#) modes; all other trim levels utilize Intelligent (I) and Sport (S) modes.

A modern Subaru 2.5L engine should have no problem lasting over 200,000 miles as long as you take care of it. There are plenty of 2.5L engines that have lasted over 300,000 miles as well when owners have done the regular maintenance on them such as oil changes, spark plug changes, and coolant changes.

A broken head gasket is one of the most common issues with the Subaru 2.5 turbo engine. A head gasket is a seal between the cylinder head and the engine block that seals in the coolant and oil, allowing them to move freely between the two components.

Common problems found on the 2017 Subaru Legacy include the windshield breaking easily, rodents chewing on the soy-based wiring, along with the transmission hesitating as it changes gears. Overall, these problems are similar to other midsize sedans, leading to average repair bills as it ages.

The 2.5i (and all 2.5i variations) include a 2.5L BOXER® 4-cylinder engine that can generate 175 horsepower and 174 lb-ft of torque. Its safety features, such as the rearview camera and advanced airbag system, are also shared features. The interior of this trim includes cloth seating and silver accents.
