“I would be driving under 30mph and would get a warning on my dashboard that would say "Brake Booster Faulty", in addition the "Brake" light would illuminate and my brakes would become spongy and harder to engage”
“While driving, the car suddenly slowed to nearly stopping and a "Brake Boost Faulty" red warning light displayed on the dashboard. I was not breaking at the time. The brake pedal felt soft and the car would not regain acceleration”
“I’ve had the “Brake Booster Faulty” error come on at least once a year. It’s very scary as the car just locks up”
