Intermittently, the cruise control buttons do not perform their proper function. When experiencing the issue, all of the following occur: 1) cancel button functions as the minus (decelerate) button, 2) the minus button functions as the plus (accelerate) button, 3) the plus button doesn't work, and 4) the off button disengages the cruise control but does not shutoff the cruise control main power. This behavior is an issue because with the cancel button acting as the minus button, the cruise control will activate with the cancel button. In addition, having the minus button function as the plus button could cause an accident if the car behaves in the opposite manner as expected. The issue occurs intermittently while driving.

While driving on the highway with cruise control on, my car atomatically slammed on the brakes and slowed down rapidly. A short time later, the forward obstruction warning indicator came on and said an inspection was needed. Mazda dealership said "never heard of that" despite similar public comments on user forums. Dealer will not cover full cost of the repair becuase care it out of warranty. I believe this is a serious safety issue that should not fall under normal warranty considerations.
