Child safety seat manufacturer Graco has recalled 3,8 million seats sold between 2009 and 2013 because "children can get trapped by buckles that may not unlatch,' according to company spokesperson.

In some reported extreme cases, the parent was required to cut the restraints to free the child.

The Graco models affected in the recall include:

Toddler convertible car seats (generally used for rear-facing infants under 30 lbs. and forward-facing toddlers up to 70 lbs. Smart Seat also converts to a booster for up to 100 lbs.)

  • Comfort Sport
  • Cozy Cline
  • Classic Ride 50
  • Head Wise 70
  • My Ride 65
  • My Ride 65 with Safety Surround
  • My Ride 70
  • Size 4 Me 70
  • Smart Seat

Harnessed booster car seats (used for forward-facing toddlers between 20-100 lbs. Argos 70 also converts to a backless booster for up to 120 lbs.)

  • Argos 70
  • Nautilus
  • Nautilus Edge

NHTSA says Graco should also recall an additional 1.8 million rear-facing infant seats with similar latches. Graco isn't recalling those seats, but will provide replacement buckles to those who request them. Those seats are:

  • Snugride
  • Snugride 30
  • Snugride 32
  • Infant Safe Seat-Step 1
  • Snugride 35
  • Tuetonia 35
  • Snugride Click Connect 40.

The company will send replacement buckles for free to customers who have registered their seats or who call the company's hotline (800-345-4109). They can also send an e-mail to consumerservices@gracobaby.com
