Should this occur, a fire hazard may be present under a worst-case scenario.
Subaru says obstructions to the wiper arms, such as snow or ice, may prevent the arms from properly returning to the ‘park’ position.
As the wipers automatically return to the park position, the wiper motor may continuously attempt to park the wipers, causing it to overheat. However, no such incidents have been reported in Australia.
Affected vehicles for both Liberty and Outback are from model-years 2010-2014, with the majority being older models.
A total of 37,492 vehicles are targeted in Australia, consisting of 17,839 Libertys and 19,653 Outbacks.
The recall process will be carried out free-of-charge, and is expected to take less than 30 minutes. Replacement parts are currently being prepared in Japan.
Subaru will attempt to contact affected owners shortly, but any owner wishing to learn more about the latest round of recalls should contact their local dealer, or phone Subaru Australia on 1300 550 994.
