Selected complaints filed with NHTSA by 2019 Mazda CX-5 owners, lightly cleaned up (personal details are redacted by NHTSA).
Infotainment Issue (Ghost Touch Issue). Mazda has been experiencing problems with the Infotainment Issue (all around the globe.. I am located in Mexico. Not sure if this channel is the right way to ask for help outside the USA); in different models such as Mazda 3, CX5, etc. My Mazda CX5 is a 2019 year model with only 10,000 miles. The "Ghost Touch Issue" started just after the 3 year warranty expired. I have the extended warranty but Mazda just confirmed this issue is not covered anymore and I need to pay approximately $1,000 US Dlls to fix the issue (and only 3 months warranty... recommendation not to park the car under the sun which for me is ridiculous). This "Ghost Touch Issue is more than an annoyance. IT IS DANGEROUS. The vehicle itself says not to play with the system while driving. …

On [redacted], I was the operator of a 2019 Mazda CX-5 in Los Angeles, California. I parked the vehicle on an incline on or around [redacted] in Los Angeles, California, and then exited the vehicle. The vehicle remained stationary for some time, until it suddenly began rolling backwards at a speed that pushed me to the ground while I was getting my things from the passenger side door, causing me serious injuries.

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. …
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. …
This is a complete electrical system failure. My screen continues scroll All Systems fails. At least it is not draining the battery again. I have had to replace the battery 2 times in the last 6 months. Maybe CarMax sold me a "lemon". . I received a recall notice, however when I spoke with the service department at the Bob Mazda dealership in Carlsbad and they told me that the recall on my vehicle is closed. I can come in for repairs, but at my own expense. I have only owned this vehicle for 6 months in which 2 months I was in the hospital recovering from a major surgery. When I get in my car and start it, if it starts the "blue" light is on every time, which is apparently Thermostat. After about 20 minutes or so the light turns off, sometimes 30 minutes. The next part is the scrolling malfunctions. It lists about everything on the car. I am [redacted] and live in Baja. …
The touchscreen digitizer on the Mazda Connect infotainment system has developed a known defect causing constant phantom/ghost touch inputs. The screen registers random touches without any physical contact, causing the system to navigate through menus, change vehicle settings (including safety-related settings such as blind spot monitoring and heads-up display), exit navigation mid-route, change radio stations, and initiate phone calls to contacts without driver input while connected to Apple CarPlay. This is a significant driver distraction and safety hazard. When the system begins making random inputs, the driver must divert attention from the road to attempt to regain control of the infotainment system or end unintended phone calls. The issue occurs most frequently when the vehicle is stopped or at low speeds but also affects the system while driving. …
Just as the recall issued for the 2014-2016 the Mazda Connect Touch Screen continues to be an issue for most owners with this Infosystem. Mine for two years since I bought it will do the "ghost touch" on its own, literally operating on its own. My settings change on their own, doing such things as the volume on its own going from a normal tone to blasting, causing such alarm that I've nearly gone off the road. My back up screen brightness changes on its own, causing a real safety concern of running into something or someone. This is just two examples...all of the functions go "haywire" and just change at any unexpected time. This issue can be seen over and over online by Mazda owners. …
