Brakes failed at stop sign. Fender bender car in front of me.
Ticketed for accident. Next day, dealer found air in ABS Modulator.
Cost of repair: $1,400. Two days to repair due to part having to be
flown in from California. Honda refuses to acknowledge low milage
rule and said warranty expired. Thank you Honda.. :(

Peddle got soft 3 different times. Went almost to floor last time. super dangerous situation. After Honda giving me the run around they finally realized there was a big problem. Air in system. Replaced ABS system and that fixed it.
i had the brakes redone and the brakes feel mushy like they still need to be bled but they dont.
