Mazda CX-5 electrical problems

My 2014 Mazda CX-5 Grand Touring has recently started experiencing an issue widely reported online related to the battery. The issue is the electrical/ignition system fails to turn the battery off when the vehicle is turned off. In other words, the car engine shuts down, but the accessory power (battery) remains on. This can be identified by the clock and dashboard display remaining on. This is a significant issue because unless the battery is turned off, it will become drained, and the car will fail to start. This can leave the driver stranded and the car incapacitated. It is very easy to fail to notice the accessory power is still on. I have reported the issue to Mazda at the customer line - 1800-222-5500 and they have no outstanding warranties or recalls related to this. My reference number is 1-4272020134. I have also contacted a local Mazda dealer and they are unfamiliar with the issue. Per customer reports, the issue is related to a faulty sensor on the battery. To reproduce the issue: 1) Put car in park 2) Push power button. Car engine turns off. Battery remains on. The only workaround is to turn the car back on, shift into different gears and turn power off. At some random iteration, it will power the battery off. There are numerous reports of this online, including - https://www.mazdas247.com/forum/t/cx-5-wont-fully-shut-off.123864884/ Solution - https://mazda.oemdtc.com/665/ignition-does-not-turn-off-when-pressing-startstop-button-2013-2014-mazda

The contact owns a 2019 Mazda CX-5. The contact stated while driving at approximately 20mph the vehicle would brake suddenly. Which resulted in the contact sustaining whiplash and sought medical treatment. The contact stated Brake warning message was displayed. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 35,000. The VIN was not available.

My vehicle does not want to turn off when placed in park. The car is fully in the park position, but the start push button is illuminated with a red light. The power is still on, and the car beeps when door is open. I can only get the power to turn off, after repeatedly tapping the gear shift left, towards the P symbol. It is already fully seated in the park position, but this finally causes the light to go off and the car turns off. Always hoping the power did not turn back on while away from the car. Is this a fire hazard? I will not park my car in the garage as I am concerned it may overheat the wiring, electrical components, etc...??? I have noticed similar complaints for this vehicle on this website also.

The center infotainment system operates by itself when driving at a low speed. The screen will automatically enter menus, place calls, and select items without any sort of input from the driver or passenger (ghost touch). The control knob, which is used to navigate the center screen, will not be functional whenever this happens. This ghost touch issue happens periodically, sometimes it goes away and sometimes the problem returns. Whenever the screen places calls or enters menus by itself, the driver is being distracted from the road and will have to focus on canceling whatever action the infotainment automatically decided to do. For example, I use Apple CarPlay for navigation but sometimes the screen will operate other functions by itself - I will have to manually click back to the navigation screen every time. A similar issue was found in the 2014-2016 MY of the Mazda3, which uses the exact same infotainment and controller setup as in the CX-5 products. I have provided a link to the relevant service bulletin here: https://static.nhtsa.gov/odi/tsbs/2019/MC-10164268-0001.pdf The system has not been examined by the manufacturer nor have there been any types of warning messages or lamps within the vehicle.

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. 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.
