2025 Honda Accord Hybrid

My 7 year old grandson was in the left rear seat and became trapped within the seatbelt, like a noose, cinching tighter and tighter causing extreme abdominal pain and trouble breathing. This occurred when the vehicle was stopped in a parking lot, AFTER THE RELEASE of the belt from the latch. He was in a booster seat with the belt across his lap and chest. To release the clasp from the latch, he had to bend over and twist his torso to his right, reaching way down to where the red relates button is almost buried between the left and center seat sections. Quite hard. At that point, the chest portion of the belt slipped over and behind his head as he was trying and trying to press the red release button. When he released the seat belt from the latch, the belt tightened across his lap and he couldn’t get out. While struggling, the belt kept retracting into the top back of the seat, getting tighter and tighter.. He pushed the booster out from under him, only for the seat belt mechanism to get tighter and tighter. 4 adults struggled, every move made it tighter and tighter. The belt had to be cut to release the child.. We are very concerned about this situation as his breathing and abdominal area was in critical distress. Why wouldn’t the seat belt allow us to pull it out of the retractor at the top left of the seat? We would like Honda to repair this at no cost to us, the car is less than 4 months old.
