“Sliding Door Sensor Failed My daughter was getting in the van, when her brother hit the door button, if my husband wouldn’t have glanced over at that exact moment and pulled her back, this would’ve been another story. THE SENSOR IS NOT SENSITIVE ENOUGH! We as mothers are demanding sensors sensitive enough to detect smaller, fragile children!”
NHTSA complaint #11728404, filed 2026-03“I purchased a new 2026 Kia Carnival EX and noticed an unusually intense amount of heat coming from underneath the vehicle on the passenger side, particularly around the rear passenger door/second-row seating area. I first noticed the issue while the vehicle was parked and I was standing outside the open rear passenger door installing car seats and floor mats. …”
NHTSA complaint #11761186, filed 2026-09“I have taken my car 3 times to 3 different Kia dealerships for this issue. First on 9/13/2026, then 10/13/2026 and on 10/26/2026. While driving at highway speed my vehicle suddenly begins to loose power and the check engine light comes on. This is dangerous for myself as well as other drivers.”
NHTSA complaint #11773840, filed 2026-10“My car has just under 3,000 miles. While driving home from a friend's house this morning my car would not go above 31 mph. I could put my pedal all the way down and nothing beyond 31 mph. I am reading a lot of people with this same exact issue with their hybrid Kia Carnival. Most note it happens in cold weather. So it is worth noting that it is 21 degrees here today. Regardless this is a serious concern especially as some report is happening on highways”
NHTSA complaint #11708175, filed 2026-01“The alert “consider taking a break” with the coffee cup symbol won’t stop going off. It goes off when I first start driving, it goes off every other minute sometimes, it does off for no reason all the time. It is so distracting. Today it was rainy and I’m sure is one reason it kept going off. It was also garbage day and someone put their garbage can on the road right on the line. The alert had gone off 15 times within my 20 minute drive after school drop off. It was making me angry and was super distracting. …”
