The contact owns a 2015 Mazda 6. While driving 5 mph and making a turn, the vehicle failed to respond when the accelerator pedal was depressed. The contact gradually applied force to the accelerator pedal and the vehicle accelerated in excess independently. The failure recurred on numerous occasions. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 55.
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. . Read more...
