One problem related to brake electric antilock has been reported for the 2006 Mazda MX5. The most recently reported issues are listed below.
The dynamic stability control (dsc) activated, dash light stayed on, while driving straight. I believe this is a safety issue due to the probability that had the pavement be slippery with rain, snow or ice the dsc braking the wheels to prevent a skid, that wasn't there, would more than likely have caused a skid, probably leading to an accident.
