Consumer Reports: 4 car seats broke during our rigorous tests
Parents with toddlers know that one of the most important products they need is a car seat, but Consumer Reports says parts of four popular toddler-booster car seats broke during recent testing.
Toddler-booster seats are forward facing car seats that can be initially used with a five-point harness and then they transition to be used as a booster with the car's own seat belts.
Consumer Reports' crash evaluations are more rigorous than the federal safety crash test requirements, which all seats must meet in order to be sold.
CR's tests of the Britax Frontier ClickTight, the Britax Pioneer, the Cosco Finale 2-in-1, and the Harmony Defender 360 found that the load-bearing components at the rear of all four seats break when tested with dummies whose weight nears the seat's limits for its harness system.
"When the structure surrounding either the harness or top tether breaks, it can compromise the seats' ability to protect the child in a subsequent crash event," says Jennifer Stockburger with Consumer Reports. "It may also allow the child to move further forward, with means they can contact portions of the vehicle interior and if the harness disengages completely, the seat in no longer restraining the child."
Consumer Reports knows of no injuries related to the structural failures revealed in its crash tests.
So what should you do if you own one of these seats? CR says you should not stop using the seat unless you have one to replace it. Any car seat is better than no car seat, and these seats all provide a basic margin of safety.
If your child weighs less than 40 pounds, you are good to keep using this seat with the five-point harness.
If your child weighs more than 40 pounds -- the minimum weight for booster use in these seats -- and can safely fit the vehicle seat belt, use the seats in booster mode.
If they're over 40 pounds, but still too small for them to fit the booster and vehicle seat belts correctly, CR says you should replace your car seat with a different, forward-facing harnessed car seat.
In statements to CR, Britax, Cosco and Harmony all reiterated the safety of their seats and noted that they meet federal standards and that CR's testing differed from the government's.
If you do need to replace your child's car seat, Consumer Reports recommends the Graco Milestone, Graco 4Ever or Chicco Nextfit.
