The 2013 Subaru Legacy represents a significant moment for the model, marking the transition to the fourth generation platform. While generally regarded as a reliable and competent sedan, potential buyers need to understand the specific 2013 Subaru Legacy problems that can arise. This specific model year sits at the crossroads of an established design and the updates needed to keep it competitive. Owning one requires awareness of the mechanical nuances that define its long-term reliability.
Common Mechanical Issues to Monitor
When evaluating a 2013 Legacy, the most frequently reported issues involve the powertrain and electronic systems. The horizontally-opposed "boxer" engine, while providing a low center of gravity, has specific maintenance requirements that differ from standard inline engines. Neglecting these can lead to premature wear. Furthermore, the integration of modern technology into the dashboard introduced new potential points of failure that were less common in earlier, more mechanical models.
CVT Transmission Concerns
Perhaps the most significant of the 2013 Subaru Legacy problems centers on the Continuously Variable Transmission (CVT). Subaru's Lineartronic CVT, while designed for efficiency, has been known to exhibit specific failure modes under stress. Owners have reported symptoms such as a high-pitched whining noise during acceleration and a sudden loss of acceleration, often described as the vehicle going "flat" or slipping. These issues can be costly to repair, as the CVT is a complex and integral part of the drivetrain for this model year.
Oil Consumption and Engine Wear
Some models within this generation, particularly those with the 2.5-liter turbocharged engine, have experienced higher than normal oil consumption. This is not always a sign of a catastrophic failure, but it requires frequent top-offs and can lead to carbon buildup if not managed. In more severe cases, worn piston rings or valve seals can cause excessive smoke from the exhaust and a noticeable drop in performance. Regular oil changes with the correct viscosity are critical to mitigating these engine-related 2013 Subaru Legacy problems.
Electrical and Infotainment Glitches
Beyond the mechanical heart of the car, the 2013 model year introduced a more sophisticated infotainment system that, while advanced for its time, has proven to be a source of frustration. Random electrical gremlins can manifest as flickering dashboard lights, unresponsive power windows, or a radio that resets itself after a battery disconnect. These issues are often related to faulty wiring harness connectors or glitches in the system's software that require dealer-level diagnostic tools to reset.
Sunroof Drain Clogs
A more minor but commonly reported issue involves the panoramic sunroof. The drains that carry water away from the roof can become clogged with leaves and debris. When this happens, water has nowhere to go and can leak into the interior, soaking the headliner and potentially causing water damage to the electronics. It is a simple maintenance task to check and clear these drains, but it is often overlooked until water damage becomes visible inside the cabin.
Fuel System and Component Failures
The fuel delivery system on the 2013 Legacy has also been a point of contention for some owners. The in-tank fuel pump can fail prematurely, leading to a sudden inability to start the car as it runs out of fuel unexpectedly. Additionally, the fuel injectors can become clogged or leak, resulting in a rough idle, poor fuel economy, and difficulty starting the engine. These issues highlight the importance of using high-quality gasoline and fuel system cleaners as part of regular maintenance.
