Graco has added another 403,000 car seats to the 3.8 million seats affected in its most recent recall. Harness buckles become increasingly difficult to unlatch, leading to safety concerns for the affected products and the families who have purchased them.

Graco released the following statement on their website:

As part of our continuous product testing and improvement process, Graco identified that some harness buckles can become progressively more difficult to open over time or become stuck in the latched position. Therefore, we have decided to conduct a voluntary recall on the harness buckles used on select toddler convertible car seats and harnessed booster seats.
As a solution, Graco offers a new and improved replacement harness buckle to any consumer who may be experiencing difficulty with their harness buckle at no cost. Consumers are encouraged to place their order for a replacement harness buckle using our online order form. Graco would like to stress that our car seats are safe and effective in restraining children. You can continue to use your car seat while waiting for your new buckle.

Graco is replacing the harness buckles with the more effective buckles seen above. A list of all models included in the recall can be found HERE, and Graco Customer Service can be reached HERE.
