2023 Kia Carnival Chest Clip, Buckle, Harness

Unknown as to what exactly happened, but my husband put my daughter in her car seat buckled her and was just fine. We arrived to our destination no more than 15 minutes later and her chest clip buckle had busted apart. I do have video of the chest clip and how it was apart, however, as soon as I get the new piece and I will not have it to show due to needing the car seat. I do have video of the incident right after I noticed it and other videos showing the parts and pieces. My daughter ended up having the pieces that you press together to unlock the magnetic chest clip apart in her mouth. The magnet circle was still in the chest clip keeping it closed and locked in place. However, it very easily could have came open and out and her eat the magnet. I have contacted the manufacturer and she let me know that other car seats have had the same problem, but there is no recall. She just said she will send me a replacement piece.

The car seat harness fails to stay engaged in a safe and secure position. When tightened to the correct position it becomes loose. I contacted Nuna and they advised I should clean the harness adjuster button from debris but I did that and the harness is still coming loose. I don’t know how many times my children have been transported while wearing this faulty harness over time since purchasing our seats in 2021 but we are in our vehicle daily so my guess is upwards of 100’s of times. The manufacturer refuses to take accountability and recommends we wait indefinitely for a new car seat fabric cover, cleaning kit and instructions to alter the car seat for the purpose of cleaning the harness adjuster button ourselves.
