NEW YORK (CNNMoney) -- Dorel Juvenile Group has recalled nearly 800,000 child safety seats because they do not always lock properly, the government said Monday.
The recall covers certain infant, convertible and booster child restraint systems that were made between May 2008 and April 2009, the National Highway Traffic Safety Administration said. The seats were sold individually or as part of a "travel system" with a stroller.
NHTSA said the harness locking and release button on the seats does not always return to its locked position, which could lead to loose straps. In the event of a crash, the child wouldn't be tightly fastened in, which could result in injuries, the agency said.
As a remedy, Dorel will send registered owners a small tube of "food-grade lubricant" that is designed to prevent sticking and ensure that the harness button works properly.
Dorel said in a statement that the recall "is being conducted out of an abundance of caution with no reported incidents or injuries."
"Parents and caregivers are being provided detailed information on how to make the simple recommended adjustments to their car seat," the company said.
