UNKNOWN While stopping the radio system (which can not be powered off) will change and go to other apps. This causes the driver to take their eyes from the road and hand from the steering wheel to press buttons to get the radio system under control. When the radio does this it often goes to the settings and changes the navigation voice volume to the loudest it can go essentially frightening the driver and causing them to look away from the road and divert their attention to the radio system. This occurs every time the vehicle is driven and often occurs when hitting the brakes.

The screen in the middle of Mazda vehicle starts selecting menu, change the radio station or selects/plays whatever it likes. It suddenly activates some functions on its own. Most likely similar issue as in this document - https://static.nhtsa.gov/odi/tsbs/2019/MC-10164268-0001.pdf This is dangerous for the driver as the automatic change in the screen and menu items distracts the driver which may cause accident and put life in danger. This is generic problem and searching on the internet, lot of people are suffering with this issue. When the issue started last year, we thought this is something random occurrence and will go away by itself but with the time, this has gone worse. Now looking in the internet we came to know this is actually an ongoing issue.

The Infotainment System has consistent "ghost touching". Not only is this a distraction while trying to drive it is changing the safety settings and display settings available in within the system such as ADAS settings and MPH\KMH speedometer options. Other less-severe options are consistently changed as well such as navigation volume etc. The problem is easy to reproduce, just need to start the car. I just paid $300 for a full replacement of the screen from Mazda, along with an update and the problem not only persists but is worse. The problem got progressively worse but there were no light indicators etc.

I was driving on the highway, at about 65 mph. The engine lost power and the car began to slow down. It did not respond to the accelerator, but the power was still on. I was lucky enough to be able to pull over to the shoulder without colliding, but it was extremely fortunate that no cars were obstructing me at the time. I put the car into park once stopped and turned the engine off. I tried to restart but the engine did not turn over and several warning signs came up on the dash and the car emitted irregular dinging/beeping noises before going silent (I do not recall specifically, but I believe the check engine and/or battery indicator lights came on) The hazards worked, also the interior lights. But I was stranded in a remote area in complete darkness on a very narrow shoulder with large trucks whizzing by. A CHP officer appeared eventually and expedited a tow truck, which brought me to the nearest Mazda dealership 100 miles away. It was midnight by the time we arrived. Both the tow truck driver and the technician (the next morning) were both unable to jumpstart the car. Engine would not turn over at all. The technician opened up the engine and sent reports to Mazda. We are waiting to hear back but they would not give me a loaner vehicle without knowing the cause of the failure. Very relieved I was not hurt but also very upset at the chance I could have been.

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.

It was 17 degrees out and the front windows would not roll down. They were not locked. When it got it into my warm garage and I let it warm up (not running) for 15 minutes, they rolled down. I have had the car a month and this is the coldest its been since I've had it. I was at a drive thru in park when they would not roll down.
