The recall issued on the Australian Competition and Consumer Commission, government website, says the problem is in the transmission. The report says it's not supplying itself with adequate lubricant. In the long-term this could mean a complete failure of third gear and eventually all drive.
Subaru says this only affects 467 cars though, and out of those cars, only a small collection - if any - might be suffering from the oil starvation problem. Known owners of the affected vehicles will be contacted via mail and asked take their car to a dealer to have the problem checked and rectified if need be. Owners concerned or unsure are advised to contact their local dealer.
