The vehicle infotainment system in this 2016 Mazda 6 no longer works and has what is called a rolling reboot. This seems a common problem with Mazda's based on a service alert SA-011/20 as well as a TSB 09-020/18. When broken I can't use the hands free to make or receive calls, nor can I modify preferences, service warnings, use the radio etc. The car is out of warranty and the part known as a connectivity master unit (CMU) is over $1000 including tax. I think Mazda should at least provide a replacement part for this very common problem, which effects many models.

MY INFOTAINMENT UNIT IS IN A CONSTANT REBOOT. I CANNOT ACCESS MY CAR SETTINGS OR RADIO OR BLUETOOTH, AND THE REAR VIEW CAMERA IS NOT WORKING EVERY TIME. IT WAS FINE AND THEN IT WASNT. I TOOK IT TO THE DEALER AND THEY TOLD ME IT WOULD BE 1500 DOLLARS. I SEE A LOT OF PEOPLE WITH THIS PROBLEM IN MY RESEARCH. I THINK THIS SHOULD BE A RECALL BECAUSE IT IS A SAFETY ISSUE SINCE I CANNOT ACCESS MY CAR SETTINGS, MY CAMERA IS NOT WORKING AND MY ALERT FOR WHEN SOMEONE IS BEHIND ME IS ALSO NOT WORKING. I HAVE A VIDEO OF THE REBOOT. IT IS ALSO VERY DISTRACTING TO BE DRIVING WITH A COMPUTER THAT IS CONSTANTLY REBOOTING. THE SYSTEM IS REBOOTING WHEN THE CAR IS ON, WHILE DRIVING AND WHILE SITTING STILL. I REACHED OUT TO MAZDA WHO SAID IT IS NOT A RECALL YET BUT IF I PAID FOR THE FIX AND THEY DID CALL A RECALL I WOULD GET REIMBURSED. A 1500 DOLLAR FIX FOR RADIO IS RIDICULOUS AND A CAR THAT IS ONLY 4 YEARS OLD. THE COMPUTER MALFUNCTIONED IS MY ONLY GUESS AND THEY SHOULD HAVE TO REPLACE IT SINCE IT IS A SAFETY ISSUE AND MULTIPLE PEOPLE ARE HAVING THE SAME ISSUE. PLEASE HELP. I HAVE A SAFETY INSPECTION DUE AT THE END OF THIS MONTH AND IM NOT SURE IT WILL PASS.

I WAS BRAKING TO A STOP AFTER DECELLERATING, DRIVING ORIGINALLY ABOUT 45 MPH. TRAFFIC WAS STOPPED IN FRONT OF ME. I WAS IN MOTION ON A HIGHWAY, GOING STRAIGHT AHEAD. MY CAR SLOWED BUT RESISTED STOPPING. I PRESSED ON THE BRAKE PEDAL HARDER UNTIL I CAME TO A COMPLETE STOP. MY RIGHT FOOT WAS ENTIRELY ON THE BRAKE, AS I ONLY USE MY RIGHT FOOT TO OPERATE THE PEDALS. THE ENGINE WAS REVVING LIKE IT WAS ACCELLERATING. THE CAR WAS IN DRIVE. NO WARNING LIGHTS CAME ON THE DASH. THE ENGINE CONTINUED TO REV HIGHER IN INTENSITY. I PUT THE CAR INTO PARK, AND THE ENGINE REVVED MUCH HIGHER. I PUSHED THE START/STOP BUTTON TO TURN OFF THE CAR. THE WARNING LIGHTS CAME ON THE DASH. I WAS ABLE TO ROLL DOWN THE POWER WINDOW EVEN THOUGH THE CAR WAS TURNED OFF. I TRIED TO RESTART THE CAR AFTER ABOUT A MINUTE. THE STARTER ENGAGED, BUT THE CAR DID NOT START. I TRIED TWICE AGAIN AND IT DID THE SAME THING. I TRIED A FOURTH TIME AND IT REACTED AS IF THE BATTERY WAS ALMOST DEAD, SOME SOUND BUT NO MOVEMENT. I COULDN'T PUT THE CAR IN NEUTRAL TO HAVE THE ATTENDING POLICE OFFICER PUSH IT OUT OF THE LANE OF TRAFFIC, AND WE NOTICED THE EMERGENCY BRAKE WAS ENGAGED. I DID NOT ENGAGE THE EMERGENCY BRAKE MYSELF! MY HUSBAND ARRIVED, AND HE AND THE OFFICER WERE ABLE TO PUT THE CAR IN NEUTRAL, HOWEVER, THEY WERE UNABLE TO DISENGAGE THE EMERGENCY BRAKE. THE CAR HAD TO BE LOADED ONTO A ROLL-OFF WRECKER TO BE TAKEN TO THE DEALERSHIP.

THIS MAZDA 6 MODEL IS EQUIPPED WITH A VIDEO DISPLAY SCREEN MOUNTED ON THE DASHBOARD THAT OPERATES THE RADIO, COMMUNICATION, AND MOST IMPORTANTLY, THE VIEW PROJECTED BY THE REAR VIEW CAMERA. UPON IGNITION, THE SCREEN OPERATES FOR ABOUT 30 SECONDS AND THEN GOES DARK AND SHUTS DOWN. THE REAR VIEW SAFETY FEATURE IS DISABLED THEREBY JEOPARDIZING PUBLIC SAFETY. THE SCREEN SHUTS DOWN WHETHER THE VEHICLE IS MOVING OR STATIONERY, ON THE STREET OR IN THE GARAGE. I NOTIFIED THE MAZDA CUSTOMER EXPERIENCE CENTER, BY LETTER, OF THE PROBLEM, BUT GOT NO ANSWER.
