Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2017 Toyota Tundra vehicles. One of the rear split bench seat leg brackets may not have been properly tightened to the vehicle’s floor pan, possibly allowing the seat to move in a crash. A vehicle with an improperly tightened seat leg bracket could fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 207, “Seating Systems,” 210, “Seat Belt Assembly Anchorages,” and 225, “Child restraint anchorage systems.”
