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.
