Certain Mia Moda Viva and Viva Supreme car seats are being recalled because the harness splitter plate on the rear of the seat has sharp edges that can cut the harness, and because the base could crack in a crash. The manufacturer is contacting registered owners and offering a full refund. You can call 1-877-546-8437 for more information. Also, read the NHTSA press release. I couldn’t find anything about the recall on the Mia Moda web site.
I highly recommend signing up for child restraint recalls from the National Highway Traffic Safety Administration.
