I bought Mazda CX30 in 2020 and the battery already starts to fail. The engine light and the battery light are on suddenly when I was driving. Then, after a while, when I restart the engine and it starts to work again. However, it happens for two times within a week. I have sent the car to the Auto Zone and the nearby car auto repair company to check the car. However, they said they cannot detect anything as the engine light and the battery light are on again this time. It is so dangerous when the car suddenly stop in the middle of the road when I was driving. I am so lucky that this accident happened during rush hour and there were heavy traffic.

Last night, after we returned home, my wife removed a cup from our vehicle's cup holder. Shortly thereafter, an extremely loud sound of static began to be heard, emanating from the car's speaker system. Regardless of what we did the sound would not turn off, and remained ongoing for a period of about an hour. Nothing happened when we turned the speaker volume down, or turned the car on or off. It was not only loud, but also quite scary. We had the car towed to the dealership, but they indicated that they could find nothing wrong. They, however, also let us know that when they contacted Mazda Mazda indicated that other cars have been experiencing similar problems. Luckily this did not occur when we were driving, because it would have been quite distracting and could have led to a crash.
