“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.
