I was driving and came to a stop at a light and all the sudden in my car just shut off. It took me a minute to try to turn it back on while cars behind me honking their horn. I’m assuming it has something to do with the electric due to the start stop button. I don’t have official incident report because I was able to get my car turned back on. I looked it up on the Internet and several people are having this issue.
