Diono is recalling 519,052 Radian R100, Radian R120, Radian RXT, Olympia, Pacifica, and Rainier convertible and booster car seats.
When the seat is secured to the car using the lap belt without also using the top tether, it may not adequately protect the child from injury in the event of a crash.
As such, these child seats fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 213, "Child Restraint Systems."
If the seat is installed with only the lap belt, the child has an increased risk of a chest injury in the event of a crash.
What to do
Diono will notify owners, and provide a free remedy kit with an updated instruction manual, an energy absorbing pad, as well as a new chest clip, free of charge. The recall is expected to begin November 22, 2017.
Owners may contact Diono customer service at 1-253-256-9939.
