Subaru WRX rod bearing failure: well-documented issue especially on 2008-2014 WRX. Contributing factors: 1) Oil changes too infrequent (these engines need 3750 mile changes). 2) Using conventional oil. 3) Aggressive driving on fresh startup. Prevention: full synthetic oil, change every 3750 miles, warm engine before hard driving. If knock starts: do NOT drive. Rod bearing replacement: $1500-3000. Full engine rebuild: $4000-8000. Aftermarket ACL or King race bearings provide better protection than OEM. Many WRX owners do bearing replacement at 60k miles proactively.
