Radio/tape Cd Player problems of the 2015 Mazda MAZDA3

The infotainment system malfunctions while the car is being operated, creating a serious distraction for the driver. For example, the system can be tuned to the radio and then it will randomly switch to the phone function and dial a number again at random from my contacts list. Trying to disengage the call doesn't work as it keeps dialing or will redial. This happens repeatedly. It will also at times choose a radio station which is not the one that has been selected. While these may sound minor they create a hazard because the driver is not able to control the communications features when they take on a life of their own.
