My problem is with the keyless start system. The problem is that if I forget to push the start button to shut down the vehicle and open the door and leave the automobile and shut the door with the key in my possession the auto will keep running until it runs out of fuel.

My problem is with the keyless start system. The problem is that if I forget to push the start button to shut down the vehicle and open the door and leave the automobile and shut the door with the key in my possession the auto will keep running until it runs out of fuel. Wouldn't it make more sense for the vehicle to shut down after 3 minutes if the key is not present. As you know people have died from carbon monoxide poisoning by parking in their garage and forgetting to shut down the vehicle and the vehicle keeps running and filling their homes with carbon monoxide. This happened to a older couple in Sarasota Florida with a new car that they just purchased and were not familiar with the starting system. Just wanted to know just how many people have to die before something is done about this problem. I asked my Mazda dealer and they told me that the vehicle will run until out of fuel and basically said that I was stupid for being concerned.

The component that failed was the CMU unit in my screen. I was unable to use Bluetooth and hands free driving which put my safety at risk and when driving at night the screen would light up, reboot, shut down, light up which was very distracting.

The component that failed was the CMU unit in my screen. I was unable to use Bluetooth and hands free driving which put my safety at risk and when driving at night the screen would light up, reboot, shut down, light up which was very distracting. I took it to the dealership which they said this is happening in cars and they will not cover it. They fixed it at a cost of $864.34. I contacted Mazda and explained how distracting this is to drive and they explained there is nothing they could do but give me a $250.00 credit.

I WOULD LIKE TO EXPRESS THAT THIS IS NOW THE SECOND TIME I HAVE HAD TO TAKE MY CAR IN FOR SERVICE AND REPAIRS DUE TO THE SOY-BASED COMPONENTS THEY USE IN THE ELECTRICAL HARNESS THAT HAVE BEEN CONTINUOUSLY EATEN THRU BY SQUIRRELS. MY CAR'S HORN AND HEADLIGHTS NO LONGER WORK AGAIN AND THIS IS NOW THE SECOND TIME. I ASK THAT THESE ELEMENTS ARE RECALLED IMMEDIATELY FOR SAFETY REASONS. WIRE HARNESSES ARE A CRITICAL COMPONENT TO VEHICLE SAFETY. WIRES THAT CAN DEGRADE DURING THE NORMAL SERVICE LIFE OF A VEHICLE CAN BE DEADLY. THINK ABOUT A WIRE HARNESS WITH INSULATION THAT'S BEEN EATEN THAT CONTROLS THE ABS, FUEL INJECTION OR AN AIRFLOW SENSOR, AND YOU HIT A BUMP IN THE ROAD AND IT SHORTS. NOW YOU LOSE POWER OR BRAKING. ARE WE WILLING TO HAVE SOMEONE'S VEHICLE FAIL AND THE PEOPLE SERIOUSLY HURT OR DEAD BECAUSE OF A FUNDAMENTAL DESIGN FLAW? I CAN EMAIL PICTURES FROM MY PHONE TO PROVIDE EVIDENCE OF THE DAMAGE. AGAIN THESE WIRES SHOULD NEVER BE SOY BASED. I DON'T FEEL LIKE DYING ANYTIME SOON BECAUSE A RODENT CHEWED THROUGH A CRITICAL COMPONENT.

I RECENTLY PURCHASED A 2016 MAZDA CX-5 FROM A NON-MAZDA DEALER, HOWEVER AFTER PAYING $21,000 FOR THE VEHICLE I REALIZED THE DAYTIME RUNNING LIGHT WAS NOT WORKING! MY BIGGEST SURPRISE WAS WHEN I WENT BACK TO THE DEALER TO HAVE THEM REPAIR IT AND FOUND OUT THE ENTIRE HEADLAMP WOULD NEED REPLACING TO THE TUNE OF $1,100 DOLLARS! TODAY I CALLED MAZDA AND THEY TOLD ME THERE IS NOTHING THEY CAN DO ABOUT THIS BECAUSE THE CAR IS OUT OF WARRANTY! IT IS ESPECIALLY DISTRESSING IN THAT SO MANY OTHER COMPLAINTS ARE ALL OVER THE INTERNET ABOUT THE SAME PROBLEM WHEN THE CARS ARE STILL UNDER 30,000 MILES! I HOPE SOMEONE CAN DO SOMETHING, MAZDA SHOULD HELP CUSTOMERS IN THIS WAY, SINCE THIS IS OBVIOUSLY A DEFECTIVE PART!
