Cruise Control problems of the 2010 Mazda MAZDA3

Drove 80 miles to destination on freeway using cruise control. Car accelerated above cruise setting on downhill - did not engine brake to hold speed. When pulling into destination hotel parking spot and with right foot on brake, engine revved dramatically. Applied both feet to break. Automatic transmission. Changed gears to n, r & p, but engine continued to rev. Turned engine off. Smoke generated from engine entered cabin. Did not use car until next day. Returning home next day used cruise control and exited freeway for break. Slowing down for stop light with car ahead and foot on brake when engine revved again as before. Shifted car into neutral and turned off car then back on. Drove car to dealer on way home without another incident. This dealer is where we purchased the care and all work except tires/alignment and battery occurred. They examined and inspected the car and kept it for the next 10 days logging 200 miles without a reoccurrence of the unintended acceleration.

Tl- the contact owns a 2010 Mazda 3. The contact stated that the cruise control sensor illuminated and stayed lit several times. The vehicle was not inspected nor diagnosed. The VIN was not available. The manufacturer was notified of the safety concern and intermittent failure. The approximate failure mileage was 90,000. Dyd.

Cruise control turns off when going down hills, even small ones. I use my cruise control daily and my drive to work contains many small hills. When cruising at 70, I go down a hill. The cruise control backs off then at the bottom of the hill, it fails to engage. Once I have drifted from 70 mph down to 60 mph, it turns itself off. I've had my car 2 months and this has happened 11 times now. The dealership claims there isn't anything wrong and the only way it can turn itself off is if I touch the brake or the clutch. I am doing neither. When on a busy highway, and this begins to happen, the people behind you get very angry. Beside the fact I have begun slowing down without my brake lights coming on. . Read more...
