I recently bought a used 2019 Sorento. The driver's side (longer one) 2nd row seat will fold all the way down. But the passenger side 2nd row seat won't fold down, no matter which lever I pull. It slides forward as soon as I pull on the side or top lever, and it leans forward just a little, but it will not fold all the way down. Seems like it shouldn't slide forward when pulling on the top lever, but should just fold forward and down all the way. Any idea on how to fix this? Thanks!
