Nuna Baby Essentials has recalled more than 600,000 of its RAVA car seats because debris may prevent the harness from staying snug. "You do not want to make contact with anything except your seat belt or car seat straps in a crash." Baer said that sand, dirt or crumbs can get caught in any car seat's harness adjuster, not just the Nuna's. When that happens, children can accidentally loosen the car seat straps if they lean forward because the locking mechanism might not work, she said. Model numbers of the Nuna car seats can be found on the label on the underside of the seat.
