We drove an hour then sat in the car while it was on for about 30 minutes. The gas tank was 14% full. We started driving again down a bit of a hill & got to a stop light. The car started beeping & said “engine off! Switch to N then start engine” We turned the car off and back on & it started working.

Unknown. My vehicle has cut off in the middle of traffic several times. Another incident was when my vehicle was shaking uncontrollably and couldn't go over 40. The check engine light never comes on. One dealership looked at it and said nothing was wrong even though one of the techs heard the vehicle. They said because the check engine light wasn't on that there was nothing that they could do. Took it to the kia dealership in Huntsville. They know something is wrong but because no check engine light or codes. They don't know where the problem is . My main issue is when something is wrong. No lights or codes show up. I haven't had it a year yet. Safety concerns with it cutting off in the middle of traffic .
