Open the full vehicle complaint log (all categories)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, AND THE DEALER CLAIMS THEY ARE UNABLE TO RECREATE THE PROBLEM ON TWO SEPARATE VISITS. THE PROBLEM HAS BEEN OCCURRING FOR OVER 18 MONTHS. I'VE FOUND THAT HITTING THE EDGE OF THE STEERING WHEEL HARD WILL CLEAR THE PROBLEM - GENERALLY FOR THE REST OF THE DAY, BUT IT RETURNS SEVERAL TIMES A WEEK. I'M REPORTING THE PROBLEM TO THE NHTSA BECAUSE AN INTERNET SEARCH HAS SHOWN SIMILAR PROBLEMS HAVE BEEN REPORTED. NO ONE HAS POSTED A CAUSE OF THE PROBLEM OR RESOLUTION. HERE IS A SEPARATE INCIDENT SIMILAR TO MINE FROM A MAZADA 6 FORUM: HTTP://FORUM.MAZDA6CLUB.COM/ELECTRICAL/350433-CRUISE-MAIN-OFF-NOT-WORKING.HTML AND ANOTHER, SEPARATE INCIDENT WITH VIDEO ON YOUTUBE: HTTPS://WWW.YOUTUBE.COM/WATCH?V=0YCU3VDFIEU&T=90S&LIST=FLB8SH0OS-Z9O2RC1I0I4ZLG&INDEX=1 AND MY POSTS ON YOUTUBE SHOWING HOW MY CAR RESPONDS. THE FIRST VIDEO IS FROM JULY 2016. THE SECOND IS FROM DECEMBER 2017.
