The 2015 Subaru Impreza 2.0i remains a compelling option for used car buyers in 2026, offering standard all-wheel drive, top-tier safety ratings, and improved fuel efficiency compared to its predecessors. While its 148-horsepower engine lacks high-end performance, its practical design and reliable mechanicals make it a sensible choice for all-weather commuting.
The Endurance of the Fourth-Generation Impreza
When the fourth-generation Subaru Impreza (GJ/GP) received its mid-cycle refresh in 2015, it aimed to address the primary criticisms of the 2012–2014 models: cabin noise, interior quality, and outdated technology. Standing here in 2026, this specific model year represents a "sweet spot" for budget-conscious buyers who require a compact vehicle capable of navigating harsh winters without the bulk or fuel penalty of a traditional SUV.
The 2015 Subaru Impreza 2.0i was available in both four-door sedan and five-door hatchback body styles. While the sedan offered a traditional trunk, the hatchback variant quickly became the enthusiast and pragmatist favorite due to its superior cargo versatility. Underneath the sheet metal, the 2015 model retained Subaru’s core philosophy: a low-mounted Boxer engine paired with a Symmetrical All-Wheel Drive (AWD) system.
Performance and the FB20 Boxer Engine
The heart of the 2015 Impreza 2.0i is the 2.0-liter, four-cylinder FB20 engine. Producing 148 horsepower and 145 lb-ft of torque, this powerplant was never designed for speed. Instead, it was engineered for efficiency and a low center of gravity. In the context of 2026, where modern turbocharged engines and electric motors provide instant torque, the 2015 Impreza can feel somewhat lethargic during highway merging or steep uphill climbs.
Transmission Choices: CVT vs. Manual
Most 2015 Imprezas found on the used market today feature the Lineartronic Continuously Variable Transmission (CVT). In 2015, Subaru revised this CVT to include simulated "shift points," making it feel more like a traditional automatic and reducing the "rubber band" sensation common in earlier units.
For those who prefer more control, a five-speed manual transmission was available on the base 2.0i and Sport Premium trims. While the manual transmission offers a more engaging driving experience, it comes at the cost of fuel economy and excludes the vehicle from being equipped with Subaru’s EyeSight Driver Assist technology.
Handling and Ride Quality
The Impreza’s suspension is tuned for comfort rather than sportiness. It absorbs road imperfections well, making it a capable long-distance cruiser. The 2015 refresh included additional sound-deadening materials and thicker side glass, which significantly reduced the road and wind noise that plagued earlier models. Steering is light and predictable, though it lacks the sharp feedback found in competitors like the Mazda3 of the same era.
The Advantage of Symmetrical All-Wheel Drive
The primary reason many buyers seek out a 2015 Impreza in 2026 is the standard Symmetrical AWD system. Unlike many "slip-and-grip" systems found in competitors, where power is only sent to the rear wheels after the front wheels lose traction, Subaru’s system is always active.
This permanent AWD layout provides a distinct advantage in heavy rain, snow, or gravel. By distributing power to all four wheels simultaneously, the Impreza maintains better stability and traction. For drivers living in the "Rust Belt" or mountainous regions, the 2015 Impreza offers a level of confidence that few other compact cars from that decade can match.
Interior Comfort and 2015 Technology Updates
The 2015 model year introduced a more refined interior. Subaru replaced many of the hard plastic surfaces with soft-touch materials and updated the center console. The most significant change was the introduction of the Starlink infotainment system, which featured a 6.2-inch or 7.0-inch touchscreen depending on the trim level.
Infotainment and Connectivity
By 2026 standards, the original Starlink system is undeniably dated. It lacks Apple CarPlay and Android Auto (which were not standard in Imprezas until 2017). However, the 2015 system does include Bluetooth connectivity for hands-free calling and audio streaming, as well as USB ports. Many current owners choose to replace the factory head unit with a modern aftermarket display to bring the car's tech up to 2026 standards.
Cargo Space and Utility
The hatchback remains the standout for utility. With the rear seats folded down, it offers 52.4 cubic feet of cargo space. This is enough to accommodate outdoor gear, small furniture, or a week’s worth of camping equipment. Even with the seats up, the 22.5 cubic feet of space in the hatch is highly usable thanks to the wide opening and low load floor.
Safety Ratings and EyeSight Technology
Subaru has long staked its reputation on safety, and the 2015 Impreza is a testament to that commitment. When equipped with the optional EyeSight Driver Assist system, the 2015 Impreza earned the IIHS Top Safety Pick+ rating.
The EyeSight system uses dual color cameras mounted near the rearview mirror to monitor traffic. In 2015, this was cutting-edge for a compact car, offering:
- Pre-collision Braking: Can apply full braking force in emergency situations.
- Adaptive Cruise Control: Maintains a set distance from the car ahead.
- Lane Departure Warning: Alerts the driver if the car begins to drift.
Even without EyeSight, the Impreza's "Ring-Shaped Reinforcement Frame" provides excellent crash protection. Standard safety features across all trims include a rearview camera, front-seat side airbags, side curtain airbags, and a driver’s knee airbag.

Living with the 2015 Impreza in 2026: Reliability and Maintenance
As the 2015 Impreza passes the decade mark, potential buyers should be aware of specific maintenance requirements and common issues associated with high-mileage units.
The FB20 Oil Consumption Issue
Early versions of the FB20 engine (2012–2013) were known for excessive oil consumption. By 2015, Subaru had implemented several engineering changes to the piston rings to mitigate this. While 2015 models are significantly more reliable in this regard, it is still recommended to check the oil levels every few fuel fill-ups, especially on cars with over 100,000 miles.
CVT Longevity
The Lineartronic CVT is generally reliable if maintained properly. However, Subaru originally claimed the CVT fluid was a "lifetime" fill, which many mechanics now dispute. In 2026, if you are purchasing a used Impreza, ensure the CVT fluid has been inspected or changed, particularly if the vehicle was used for towing or driven in mountainous terrain.
Common Wear Items
- Wheel Bearings: Subarus of this era are known for premature rear wheel bearing wear. Listen for a low-frequency hum or growl that changes with vehicle speed.
- Lower Control Arm Bushings: These often tear or dry out after 10 years, leading to "clunking" noises over bumps or vague steering.
- Valve Cover Gaskets: Like many Boxer engines, small oil leaks from the valve covers can develop over time.
Comparing the 2015 Impreza to its Rivals
In 2015, the compact car segment was incredibly competitive. Here is how the Impreza stacks up against the top sellers of that year when viewed from a 2026 perspective.
- Honda Civic (2015): The Civic offers better predicted long-term reliability and a more traditional automatic transmission. However, it lacks AWD, making it less suitable for snow-heavy climates.
- Mazda3 (2015): The Mazda3 is significantly more fun to drive and has a much more premium interior. However, its rear seat is cramped, and like the Civic, it was front-wheel drive only in 2015.
- Toyota Corolla (2014-2015): The Corolla is the king of reliability and low running costs. Its technology is even more basic than the Subaru's, and its driving dynamics are uninspired, but it holds its value exceptionally well.
The Subaru Impreza carves out its own niche by being the only vehicle in this group to offer AWD across all trims without stepping up to a much more expensive luxury brand.
Cost of Ownership and Fuel Economy
One of the 2015 Impreza’s greatest achievements was its fuel economy. Prior to this generation, owning an AWD vehicle usually meant a significant penalty at the pump. The 2015 Impreza 2.0i with the CVT is EPA-rated at 37 mpg on the highway.
In 2026, real-world data suggests that high-mileage units may see a slight dip in these numbers, typically averaging 30-32 mpg in mixed driving. Maintenance costs are slightly higher than a front-wheel-drive Toyota or Honda due to the complexity of the AWD system (requiring matched tires and differential fluid changes), but they remain well within the "affordable" range for a compact car.
Frequently Asked Questions
Does the 2015 Subaru Impreza have head gasket problems?
The 2015 Impreza uses the FB-series engine, which features a multi-layered steel head gasket design. This is a significant improvement over the older EJ-series engines (found in Imprezas prior to 2012) which were notorious for head gasket failures. While any engine can have issues at high mileage, head gasket failure is not a common or systemic "type-fault" for the 2015 model year.
Is the 2015 Impreza underpowered?
With 148 horsepower, the Impreza is one of the slower cars in its class. It is perfectly adequate for city driving and maintaining highway speeds, but it can struggle when fully loaded with passengers and cargo or when trying to pass on a two-lane road. The CVT's tendency to hold the engine at high RPMs during hard acceleration also makes the cabin quite loud during these maneuvers.
Can I add Apple CarPlay to a 2015 Subaru Impreza?
Yes. Because the 2015 Impreza uses a standard "Double-DIN" radio size, it is relatively straightforward to install an aftermarket head unit from brands like Sony, Pioneer, or Alpine. This is a popular upgrade in 2026, as it allows for modern navigation and smartphone integration while retaining the car's existing backup camera and steering wheel controls with the correct wiring adapters.
How many miles can a 2015 Subaru Impreza last?
With diligent maintenance, a 2015 Subaru Impreza can easily exceed 200,000 miles. The key to longevity for this specific model is regular oil changes (every 5,000 to 7,500 miles) and ensuring the cooling system and CVT are serviced. Rust is the other major factor; because these cars are popular in snowy climates where road salt is used, checking the underbody for corrosion is essential.
Is the 2015 Impreza 2.0i good for tall drivers?
Surprisingly, yes. The Impreza has one of the more airy and spacious cabins in the compact segment. The 2015 model offers excellent headroom and a wide range of seat adjustments. The thin A-pillars and large glass area also provide some of the best outward visibility of any car produced in the last decade.
Final Recommendation: Should You Buy It?
The 2015 Subaru Impreza 2.0i is an excellent choice in 2026 for drivers who prioritize safety, visibility, and all-weather capability over raw speed or modern "flash." It is a "no-nonsense" vehicle that performs its primary duty—getting you to your destination safely—regardless of the weather conditions.
If you are looking for a used Impreza, prioritize a Premium or Limited trim hatchback that has a documented service history. If safety is your top concern, seek out a model equipped with the EyeSight system. While it may not be the most exciting car on the road, its combination of standard AWD and high safety ratings makes it one of the most practical used car investments available today.
Before finalizing a purchase, always have a pre-purchase inspection (PPI) performed by a technician familiar with Subaru Boxer engines to check for common oil leaks and to verify the health of the CVT.
