2022 Hyundai Palisade Seat Belts

Our vehicle has captain seats in the middle row. The seat buckles are so far recessed it's ALWAYS difficult to buckle, especially when using car seats or boosters. Our children, nearly 9 and 7 years old who had no difficulties buckling before, are unable to buckle themselves with their boosters now. Additionally, and even more concerning, is that the seat belt will "click" as if it's been buckled but come unbuckled partially through the drive. I have found I have to get two clicks and/or yank on the buckle to ensure it's all the way in. But for children it's confusing as they're unsure if they've buckled correctly. A Hyundai dealer inspected it and stated it as a known problem but that there's nothing that can currently be fixed about it. However, I worry if in an accident the seat belt may actually come undone as it's not all the way in most of the time.
