Consumer Description

Couple weeks back, significant other encountered issue with brake signal coming on and needed to pretty much press the brakes to the floor to get it to brake. Took it to a nearby shop and they weren't familiar with the car, so they recommended to bleed the brakes according to error code and online. Signal went away for a bit. Signal came back with no immediate brake issue. Took to the dealership and they replaced some parts which also made the signal disappear for now. The parts were: Booster brake (a booster asy - brake), a bush, a module. Assuming the part replacement effectively hid the issue like a brake bleed. Few days later while driving about 40mph later the brake signal came on, wasn't touching the brakes at the time. Went to brake and they weren't reacting normally and wasn't braking. Had to also pretty much press hard on the pedal and get the pedal to the floor to break. Pulled off to a side road and restarted the car. Issue disappeared upon restart. Assuming something that controls the brake booster turns off.
