NHTSA Complaint #11526804 — 2023 KIA CARNIVAL

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 .
