Had my 2015 Honda Accord ex-l in for service today, and asked them to check the brakes because the pedal was soft again. In the last year to try and correct the soft pedal I have replaced the pads and rotors, and a few months had the brakes bled. Dealership tells me they have seen issues with the master cylinder, lucky I had the extended warranty so it will only cost me the deductible but there is something wrong have master cylinder problems at 36000 miles.
