Transport Canada recalls

Seats And Restraints#2024718November 25, 2024
25,106 units affected
Issue: Certain child seats may not meet the requirements of the Canadian regulations when installed in a rear-facing position using the universal anchorage system (UAS). Safety Risk: A child seat that doesn't meet the requirements of the Canadian regulations could increase the risk of injury in a crash. Corrective Actions: Diono advises that you may continue to use the seat in a rear-facing position if you install it using the vehicle seat belt. Diono will notify registered owners in writing. You should contact Diono to obtain a free remedy kit that includes a foam insert and instructions for how to install it. If you have not yet registered your seat, have moved, or have any questions about this recall, you can contact Diono at: 1-866-954-9786 or https://diono.ca
Seats And Restraints#2022745December 28, 2022
43,768 units affected
Issue: On certain child car seats, the owner's manual doesn't provide clear instructions for how to lock the vehicle seat belt when using the seat in a rear-facing position. UPDATE - After further discussions between Diono and Transport Canada, it was determined that this issue is unlikely to affect safety. Safety Risk: This small omission is unlikely to affect safety, as Diono has indicated that the child seat has a seat belt lock off tool that allows an owner to lock their vehicle car seat belts without using the vehicle's seat belt ratcheting system. Corrective Actions: This is not a recall. Owners can continue to use their seat. Diono has made changes to correct all future owner's manuals. Owners can download a copy of the updated owner's manual at: <a href= https://diono.ca/asset/639c4b97220f0/Radian%C2%AE%203RXT%C2%AE_Manual_NA.pdf > https://diono.ca/asset/639c4b97220f0/Radian%C2%AE%203RXT%C2%AE_Manual_NA.pdf</a>. Owners can also contact the company if they have any questions on how to use the seat.
