Your car's Nuna car seat has a safety issue where the harness adjuster strap loosens during use, even though the seat was made after a recall. The harness strap can move freely while your child is in the seat, which means it may not keep your child properly secured. The manufacturer's response to your report was slow and unhelpful. Fixing this will require replacing the defective car seat with a working unit.
