The US company Evenflo has issued a voluntary safety recall of its Discovery Infant Car Seat Models 390, 391, 534, 552.

In an advisory published on its website the company said that the seats affected by the recall are those produced beginning April 2005. Evenflo said thath close to one million units could be affected by the recall.

The recall was issued after recent laboratory tests conducted by Evenflo and the National Highway Traffic Safety Administration, which show that this car seat could potentially become separated from its base in high impact side collisions similar to those in the tests.

The owners of the recalled models will be provided with a free supplemental dual-hook fastener that has proven that the seat remains attached to the base in the event of such collisions. Additionally, Evenflo is taking steps to develop future models of Discovery with enhanced safety performance. These new Discovery models will be available to consumers starting in the second quarter, 2008.

“We are parents, too, and protecting children is our core mission at Evenflo. While our current Discovery car seat models have performed well to protect infants in actual side impact automobile collisions without any reports of serious injury or death since they were introduced, we want to take further steps to protect the safety of children who use our products,” said Rob Matteucci, CEO of Evenflo.

The customers who owns these models should call should call Evenflo at 1-800-356-2229 between 8 AM and 5 PM EST or visit www.evenflo.com/Discovery.
