“My 2021 Hyundai accent has randomly not started a in more than 10 different times. The lights go on and you can hear it trying to start but it never catches to actually start. It’s under warranty but the dealer says if they can’t see it when it’s happening then they can’t fix anything. I bought a new battery with dealer recommendations but I still hace they problem. I only have 25,300 miles on this 2 year old car.”
