Graco Childrens Products Inc. on Wednesday announced the voluntary recall of 2 million Quattro Tour and MetroLite brand strollers after four infants died of strangulation.

Reports of entrapment resulting in cuts and bruises have also surfaced. When unharnessed, an infant can slip through the opening between the stroller tray and seat bottom, and the infant's neck can become entrapped, which can result in strangulation, the U.S. Consumer Product Safety Commission said in a statement.

The strollers were sold mainly in at AAFES, Babies R Us, Burlington Coat Factory, Fred Meyer, Kmart, Meijers, Navy Exchange, Sears, Target and Walmart between November 2000 and December 2007.

For the list of models subject to the recall, refer to For additional information, consumers can contact Graco at (800) 345-4109 between 8 a.m. and 5 p.m. ET Monday through Friday.

Consumers are advised to stop using these strollers immediately and to contact Graco for a free repair kit.

The CPSC has issued a safety alert to parents reminding them to always ensure their children are securely harnessed in the stroller at all times and are never left unattended in the stroller.
