Which Diono Cambria 2 Booster Seats Are Affected?

- Cambria 2 model 31201-US-01

The serial number sticker on each seat tells owners whether it is in the recall. The carton product label shows the same six digits as the P.O. #. Contact Diono if you are unsure whether your seat is included.
Why Were the Diono Cambria 2 Booster Seats Recalled?
The Diono Cambria 2 booster seats were recalled because a crack can form between the headrest and backrest in a crash. The headrest can then separate, and the seats fail Federal Motor Vehicle Safety Standard 213, Child Restraint Systems.
Diono found the problem through continuous product testing, according to TIPP. NHTSA states that a broken or separated headrest increases the risk of injury during a crash. The recall applies only to seats bearing the serial numbers Diono listed.
