My 2013 Kia Optima won't start, all of a sudden......
a couple weeks ago, after a full days work, I would start my car and right after it would very briefly "chug a lug" for a split second but then be fine. it was even fine in the mornings after sitting all night. However, yesterday, I was vacuuming inside and head my radio on for probably 30 minutes, and went to start afterwards and it won't start. it's a push button. could it be my battery even if the lights will turn on inside the car? I should reiterate, my car started fine 30 minutes earlier to move it to where I wanted to vacuum it, then 30 minutes later, won't start at all. thank you
