“I purchased this 2024 Kia Carnival on 2/7/2026 with less than 10K miles. The vehicle has died while I was driving 4 different times. Twice each day that it happened. The first time was on 4/7/26. My car died on the way home from getting my kids from school after fixing a flat tire. The check engine light came on after getting a jump and when I took it to Auto Zone the battery was fully charged and the codes were for the Power Train, which didn't make sense for a brand new car. Miracle Mart told me that Kia needed to be utilized for any issues because I purchased the vehicle as is. …”
NHTSA complaint #11734099, filed 2026-04“Continuous engine oil leak for 12 months. After 4 failed repair attempts, the dealer used liquid sealer instead of a gasket. This is a deceptive repair that creates a severe fire hazard. The leak is still active today, March 2026.”
