The vacuum pump on my vehicle has gone out for the 3rd time in 2.5 years. This creates a safety issue as that the brakes stop working and it takes an extreme amount of pressure for the car to stop. This has occurred once on the freeway and twice in heavy traffic areas. This could cause an accident and potentially seriously hurt or kill someone.
