There are 3 owner-reported speed control & cruise complaints for the 2011 Mazda CX-7in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
CAR ACCELERATES WHEN IDLING IN DRIVE OR REVERSE EVEN WITH FOOT ON BRAKE. CAUSES MANY NEAR ACCIDENTS WHEN PARKING OR IDLING. SEEMS TO BE CONNECTED WITH AC COMPRESSOR. THIS IS VERY DANGEROUS AND SHOULD BE RECALLED AND FIXED.
I WAS DRIVING AT A NORMAL RATE OF SPEED ON A FAIRLY BUSY STREET WHEN THE CAR JUST SUDDENLY DECELERATED, CAUSING THE CAR BEHIND ME TO SWERVE TO NARROWLY AVOID ME. THANKFULLY HE ALSO AVOIDED HITTING ANYONE ELSE. MY CAR CONTINUED TO MOVE FORWARD, BUT WITH NO ABILITY TO ACCELERATE. I MANAGED TO GET CLEAR OF TRAFFIC AND WAS ABLE TO GET THE CAR TO A REPAIR PLACE NEARBY. I WAS TOLD THAT THE ENTIRE THROTTLE BODY WAS BAD, AND THAT IT WOULD HAVE TO BE REPLACED. THE CAR IS A 2011, LESS THAN 60K MILES ON IT WITH REGULAR OIL CHANGES AND HAS NEVER HAD ANY ISSUES UNTIL THIS. THE COMPLETE AND IMMEDIATE DECELERATION SEEMS QUITE DANGEROUS IN MY OPINION. AND HAVING DONE SOME READING ONLINE, THIS SEEMS TO BE A FAIRLY COMMON PROBLEM THAT MAZDA IS AWARE OF YET HAS DONE NOTHING TO RECTIFY.
THE CAR HAS A ACCELERATION PROBLEN WHEN YOU ARE ON A DRIVE ON A STOP POSITION OR ON A RED LIGHT.
