Diono Cambria 2 Booster Seat


Diono is recalling certain Cambria 2 booster seats manufactured between September 5, 2020 and November 30, 2020.

Recall Information

Diono is recalling certain Cambria 2 Booster Seats, model numbers 31200-US-01, 31201-US-01, and 31202-US-01. In the event of a crash, a crack between the headrest and backrest can occur, allowing the headrest to separate. As such, these seats fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 213, “Child Restraint Systems.”

Diono has determined through continuous product testing, that certain Diono Cambria 2 booster seats (model numbers 31200 US-01, 31201-US-01, and 31202-US-01), and only those bearing the serial numbers listed below, fail to conform to Federal Motor Vehicle Safety Standard 213 (FMVSS 213). Only the serial numbers listed below are affected.

Out of an abundance of caution, Diono has elected to voluntarily conduct a recall on the affected seats. All affected seats will be remedied at no charge to the owner. Diono will ship a replacement backrest / headrest to all owners at Diono’s expense. Diono expects that the replacement headrests will be available for shipment by May 9, 2021, but the replacement headrests may be available before that time.

You may continue to use the seat as a backless booster while waiting for the replacement backrest. The affected units meet FMVSS 213 requirements when used as a backless booster.
