Federal safety regulators are investigating complaints that children have been trapped in Graco car seats because the buckles won't unlatch.
The National Highway Traffic Safety Administration says the probe covers My Ride and Nautilus seats from 2009 through 2011.
The agency says it has 25 reports of problems from consumers. Some had to force the buckle open. Three told the agency they had to cut the harness to free their child. Six more say they had to pull the child through the harness.
No injuries have been reported.
The agency did not say how many car seats were affected. Investigators will decide if the seats should be recalled. They have asked Graco for information about other seats with the same parts.
A message was left for a Graco spokeswoman.
