ABS light came on constantly.... followed by emergency brake light within a year.... but they disappear during the cold Buffalo NY winter, leading me to believe some control goes berserk during warmer weather. Everytime it warms up to above about 50 degrees F, the lights come on and remain on until the next winter. My mechanic could not figure it out....and I don't know if only the lights or the actual brakes are dysfunctional.
