Known Issues Oil Consumption:
Some EJ25 engines, particularly early naturally aspirated ones, could exhibit higher-than-average oil consumption. Regular checks are recommended.
Known Issues Cv Joints:
Front CV axle boots can wear and tear, leading to premature failure of the CV joints. This is common in vehicles driven in harsh conditions or with modified suspension.
Known Issues Exhaust Manifold:
Cracked exhaust manifolds can occur due to thermal cycling, leading to exhaust leaks and a ticking noise.
Known Issues Rear Differential:
Regular differential fluid changes are important to prevent wear and noise, especially on AWD systems.
Brand Heritage:
Subaru, a division of Subaru Corporation (formerly Fuji Heavy Industries), has a long history of producing aircraft and, since the 1950s, automobiles known for their boxer engines and Symmetrical All-Wheel Drive systems, emphasizing safety and reliability.
