The recall was issued after concerns about the seats' ability protect children from the impact of a crash arose. When these seats are fastened to a car using a vehicle's lap belt without a top tether, they may not completely protect children in the event of a crash, and so they don't comply with the 213rd requirement of the Federal Motor Vehicle Safety Standard guidelines. Kids who are fastened with just the car's lap belt are at increased risk for chest injuries because of this.
The following models are included in this recall: Radian R100, Radian R120, Radian RXT, Olympia, Pacifica, and Rainier convertible and booster car seats.
So what should you do if your child's seat is involved? If you have registered your car seat, you can expect a notification from Diono. In the meantime, you can call the company's customer service at 1-253-256-9939. Diono will also reportedly provide anyone who has purchased any of these models with a free remedy kit, an updated instruction manual, and a new chest clip. The recall goes into effect on November 22.
