Subaru Legacy 5th Generation Review (2009-2014)

Hey there!

If you're thinking about buying a 5th-generation Subaru Legacy, or if you already own one and want to better understand its design and potential weak spots—you've come to the right place.

In this article, we'll take a close look at the Subaru Legacy 5th generation, produced from 2009 to 2014. This generation marked a turning point in the model's history: it was the first to feature a CVT, new naturally aspirated engines, and diesel variants. Alongside the CVT came a new all-wheel-drive system with a crossover-inspired approach, using a hydraulic multi-plate clutch to engage the rear axle. This setup was more suited for everyday drivers but still retained Subaru's distinctive driving character.

And yes, everything we'll discuss here also applies to the 5th-generation Subaru Outback, as they're nearly identical mechanically—especially in terms of platform, engines, and transmissions.

We'll cover the body, interior, engines, transmissions, and various systems. We'll highlight common issues, engineering decisions, and ownership tips. This article is helpful whether you're shopping for a used Legacy or just want to understand your current car better.

So buckle up—we're diving into what makes the Subaru Legacy BM/BR (5th generation) special, and where it needs a little extra care.

1. Bodywork and Corrosion Issues

Body Characteristics

As with most Japanese cars from that era, the paint and clear coat layers on the Legacy's body are quite thin. This means that frequent exposure to road debris or low-quality car washes can quickly dull the vehicle's appearance. However, corrosion resistance is generally good—rust is rare on well-maintained vehicles up to 15 years old.

That said, the roof panel is particularly vulnerable. If the paint is chipped, rust may develop more quickly there. Another issue to be aware of is the xenon projector lenses, which can burn out over time, reducing headlight effectiveness.

Ride Height Sensor Problems

The ride height sensors on the left side of the suspension can also fail. These are responsible for adjusting the headlight angle, and if they malfunction, proper light adjustment becomes impossible. Regular cleaning and greasing of the sensor linkage can help, but if failure occurs, the sensor needs to be replaced.

2. Engines and Common Issues

EJ Engines

The Legacy 5th gen came with EJ-series engines, which date back to 1989. Most common are the 2.0L and 2.5L variants, along with the turbocharged EJ255.

Oil Consumption

Many Legacy owners report high oil consumption, varying from half a liter between oil changes to half a liter per 1,000 km. If consumption exceeds these levels, an engine rebuild may be required. Using high-quality, OEM-spec oil and keeping change intervals under 8,000 km helps reduce the risk.

Overheating and Head Gasket Issues

EJ engines are also prone to overheating, which can cause head gasket failure or even cylinder head warping. To prevent this, regularly clean and inspect the radiators. A knocking sound in cylinder #4 can be a symptom of overheating or cylinder wear.

FB Engines and Diesel Variants

Later Legacy models used FB-series engines, including 2.5L gasoline and diesel options. These feature a timing chain and hydraulic lifters, offering better efficiency—but they also suffer from oil consumption issues, which can cause serious engine damage if ignored.

3. Transmissions: What to Know

Lineartronic CVT

The Legacy 5th gen introduced the Lineartronic CVT (TR690), a significant upgrade over previous Subaru transmissions. It's considered one of the most reliable CVTs in its class, especially when paired with the symmetrical AWD system.

Solenoid Issues

Despite its strengths, the CVT can develop issues, particularly with hydraulic solenoids in the valve body. These may fail around 200,000 km, requiring diagnostics and possible replacement.

Torque Converter Bushing Wear

Another issue is torque converter bushing wear, particularly in early models. This may cause the engine to stall during deceleration or stops. Fixes include replacing the bushing or installing an upgraded bearing.

CVT Maintenance

To prolong CVT life, regular fluid changes are essential—every 60,000 km for partial changes and every 100,000 km for a full flush.

Jatco JR507E Automatic

Higher-powered versions (like the 2.5L turbo or 3.6L flat-six) use the Jatco JR507E 5-speed automatic, which is generally reliable. However, it can fail under aggressive driving, especially due to overheated transmission fluid. Monitoring fluid condition and timely replacement is key.

4. Radiator and Cooling System Issues

Cooling System Weak Points

The Legacy's radiator features an integrated oil cooler, which reduces cooling efficiency. In hot weather or with clogged radiator fins, the cooling system can become overwhelmed, risking engine overheating and head gasket failure.

It's important to regularly inspect and clean the radiators—especially for vehicles with over 100,000 km.

5. Braking System & Maintenance

Brake Caliper Issues

The brake calipers require periodic maintenance, including lubrication of the guide pins and replacing repair kits when necessary. If neglected (e.g., for over two years), calipers can cause uneven pad wear, squeaking, or knocking sounds while braking.

Final Thoughts

The Subaru Legacy 5th generation is a car with a strong personality. It might not be perfect mechanically, but it wins you over with reliable AWD, good handling, ride comfort, and that unmistakable Subaru spirit.

Yes, there are concerns—CVT maintenance, oil consumption on some engines, thin paint, and limited soundproofing. But if you go for a naturally aspirated EJ20 or a diesel with manual transmission, keep up with maintenance, and regularly inspect the drivetrain, the Legacy can be a dependable companion for many years.

This car is a great choice for drivers who:

• Value all-weather confidence and stability

• Are willing to invest a bit more care than just oil changes every 15,000 km

• Want a dynamic wagon (or sedan) that's not an SUV

• Don't mind occasional (or even major) repairs in exchange for driving pleasure and style

Before buying, make sure to:

• Inspect the CVT thoroughly (especially on 2.5i models)

• Diagnose the rear clutch pack (essential for AWD health)

• Check for leaks in the engine and steering rack

• Look under the car for rust, especially if it's from a region near the ocean

If everything checks out—why not? The Legacy BM/BR is a balanced, soulful car that can still bring tons of joy even on the used market. Just know what you're getting into, and be ready to bond with your Subaru—not just drive it.
