a warning light came in on my dashboard brakes regarding the Brake pump accumulator. It feels like my brakes are not working right, not stopping like they always did.I was scared I almost hit someone in front of me at a red light because after applying the appropriate notes due on the brake pedal I noticed a delay in the car stopping. I had the brakes checked by a mechanic and they are ok. This is very dangerous. Can the manufacturer be required to repair this defect? Thank for your help.
