On 11/12, my 2024 Kia Carnival was parked as my children were getting settled in the vehicle. My son lifted the second-row passenger seat on the passenger side using the handle provided to access the third row. As he did so, the seatback suddenly collapsed forward with unexpected speed and force and locked in the forward position. Nothing broke, and the mechanism did not appear to jam. The seat moved along its normal path, but it did so so aggressively that it crushed my [XXX] daughter’s lef

A/C system on my 2024 Kia Carnival failed twice within weeks. First at 60,100 miles, repaired at dealership for $398. Then again shortly after, leaving vehicle undrivable in summer heat. Kia has done nothing despite having a case number (#25267950). This is a recurring failure that affects safety and comfort during high-temperature seasons. I believe this is a manufacturer defect and request a formal investigation.
