Honda (American Honda Motor Co.) is recalling certain 2018 Honda Pilot and Ridgeline vehicles and 2018 Acura MDX vehicles. The front driver and passenger powered seats in the Honda vehicles and the driver powered seats in the Acura vehicles may have been assembled with improperly manufactured rivets.

Consequence: In the event of a crash, if the seat does not remain secured to the floor, the seat occupant has an increased risk of injury.
