Summary Verdict

The 2018 Subaru Forester demonstrates commendable reliability, with the 2.5L engine being the most common source of reported issues, primarily related to oil consumption and potential head gasket leaks, though these are not universal. The turbocharged engine variants can experience turbocharger or direct injection system issues. The CVT transmission, while generally robust, has seen some reports of fluid leaks or overheating. Electrical gremlins, particularly with the infotainment system and occasional battery drain, are also noted. The manual transmission, suspension, exterior, and interior components are largely free from widespread significant problems. Regular maintenance, especially for the CVT fluid, is crucial for long-term dependability.
