NHTSA complaint #11434110

Owner complaint summary

I was stopped while waiting for kids to get in the car and I heard a loud hissing noise. The noise stopped when I released the brakes. Each time I pressed the breaks, the hissing continued - no matter how long the brake pedal was being pressed. The dealership seemed very unconcerned and told me it would be two weeks before I could even get in for a diagnosis. In the days leading up to the appointment, I was on the freeway going 55mph. A car in front of me stopped quickly and I slammed on the brakes as hard as I could. We slowed down, but did not stop nearly as quickly as one would hope. We barely missed hitting the car in front of us. We drove immediately to the dealership and left the van with them until our appointment time. The part needed to fix it (Brake Booster) is on backorder and our van will now be sitting at the dealership for who knows how long. There were no warning lights on the car, so I did not suspect the issue was this bad. The hissing had only began less than two weeks prior. Car only has 30,000 miles on it and has been up to date on maintenance.
