A total of 1652 current-generation Prius hatchbacks manufactured between October 2008 and October 2009 are affected in Australia.
The official recall notice published on the Australian Competition and Consumer Commission (ACCC) website explains that there is the possibility that a fatigue crack could develop inside the accumulator within the brake booster pump assembly.
“If cracks occur in the accumulator, nitrogen gas could leak into the brake fluid and cause the brake pedal stroke to become longer or the pedal to become spongy, increasing the stopping distance and the risk of a collision.”
Toyota Australia will contact affected owners directly early next month when parts arrive instructing them to arrange a time to complete the recall service at their local dealership.
All affected vehicles will be inspected and, if necessary, have their brake booster pump assembly replaced – a process that takes about three hours.
