The 2015 Subaru WRX represents a pivotal moment in the brand’s history, marking the debut of the new generation boxer engine and a complete redesign of the platform. For enthusiasts, the question of 2015 WRX reliability is often intertwined with the excitement of driving a car that finally delivers on the promise of the original STI lineage. Understanding the long-term durability of this model requires looking beyond the initial thrill of the turbocharged punch and examining the engineering decisions, common wear items, and real-world maintenance records that define its ownership experience.
Engineering Foundation and Build Quality
At the heart of the 2015 WRX is the FA20DIT horizontally-opposed turbocharged engine, paired with the brand-new Subaru Global Platform. This platform was a significant step forward for Subaru, utilizing high-tensile steel and a rigid box-section chassis to improve handling and safety. From a reliability standpoint, the foundation is robust; the platform’s design minimizes flex and provides a stable base that should, in theory, contribute to the longevity of the chassis and suspension components. The shift from a legacy naturally aspirated design to a complex turbocharged system introduced new potential failure points, but Subaru’s engineering generally aimed for durability rather than peak performance numbers.
Common Issues and Known Weaknesses
No vehicle is perfect, and the 2015 WRX has its share of reported issues that owners should be aware of. Early production models, particularly from the 2014 model year carryover, were known for excessive oil consumption, a problem that Subaru addressed with an extended warranty program. While improved for the 2015 year, it remains a concern for high-mileage examples. Owners have also reported issues with the infotainment system freezing, sunroof leaks, and premature wear on the CVT transmission, especially in models subjected to frequent hard acceleration. Being aware of these specific problems allows for proactive inspection and maintenance.
Maintenance Requirements and Costs
Maintaining a 2015 WRX is more involved than maintaining a standard sedan, but it is far from exotic. The boxer engine design means that oil changes are slightly more complex and often more expensive than on a comparable sedan, as the oil filter is mounted underneath the engine. Regular adherence to the Subaru maintenance schedule is crucial for reliability; this includes using the correct synthetic oil grade and paying attention to the timing of transmission fluid changes. Budgeting for these routine services, along with the standard wear items like brake pads and tires, is essential for long-term ownership.
Tires, Suspension, and Driving Dynamics
The WRX’s performance-oriented suspension is a joy on the open road but can be demanding on daily wear. Owners frequently report that the stock all-season tires wear out quickly, especially if the car is driven enthusiastically. Replacing them with a quality all-season or performance tire is a common modification, but it is a necessary one for those who put significant miles on the car. The suspension components, while well-built, can develop clunks and rattles over time, often attributed to the aggressive nature of the standard settings or wear in the sway bar links.
