i thought the same about not going back , but they have treated all my cars well for many years now, they even admitted finally this car was beyond their scope. they also told me after asking that it was the front passenger side speed sensor cable, they simply spliced in new wire, instead of a new harness, the battery seems fine, especially since it was replaced about a year ago, could it be bad so soon? they also said they allowed a newer technician work on my car which isnt reassuring... it has to be an electrical issue. i also disconnected the battery for a minute... the ,abs and esp light still came back on... im at a loss. i fear i may have to take it to the local stealership Monday... cars never given me problems untill this brake job.. and i dont blame the car... or rats
