Toyota PRIUS
What the hazard is
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.
What to do
Customers will receive a letter instructing them to take their vehicle to their preferred Toyota dealer for inspection and, if necessary replacement of the brake booster pump assembly.
Defect
There is a possibility that a fatigue crack could develop inside the accumulator within the brake booster pump assembly.
