The documented engine faults that affect this version and its years, from most to least important.

  2. 2High severityFrequency: RareCylinder head and blockValve spring breakage on models built in 2013 and 2014In 2019 the DVSA recorded a recall for possible valve spring breakage on the Forester, Impreza, XV, Outback, Legacy and BRZ built in 2013 and 2014 (812 cars in the UK); the fix is to replace all the springs.
