There are reports that the strollers caused a fingertip amputation and two lacerations.
The injuries happened while the strollers were being folded and unfolded.
The recall includes sport v2 and classic v1 models sold at specialty juvenile stores from May 2008 through July 2010.
It affects about 22,000 strollers in the United States and 7,200 in Canada.
Consumers are advised to stop using the strollers and contact phil&teds USA at (877) 432-1642 to arrange for the shipping of a free hinge-cover kit.
