The driver-side second-row seatbelt goes slack for no reason while driving. All tension is released, and the loose belt falls forward. This is a serious safety issue for the child riding in that seat with no working seatbelt. This has happened about a dozen times on various days while driving. The dealer first denied there was a problem, then they claimed they fixed it. But it is still happening.
