My 2016 Honda accord battery completely failed twice in one day. Wouldn't start. I boosted it and went to my dealer. I was informed that the battery life was over and I needed to get new battery. I was also informed that my car warranty doesn't cover the price of a new battery. I missed my work because of this issue and now I had to pay for a new battery. The payment didn't bother me as much as the fact that my 2 years old car battery failed completely. It was unheard and shocking. To me. This car is not my first car. I had 4 cars before including 2006 Honda civic. The battery on my civic lasted 7 years and was still running until I sold it. I really would like to know why and how brand new car battery failed . I am disappointed and feel betrayed.
