What Do Car Seat Expiry Dates Mean?
Car seats – just like anything else you use in daily life, have an expiry date. They are designed to protect your child from injuries in the vehicle, with taking your baby in and out.
If you use a car seat beyond its expiry date, you’re putting your child at potential risk. The materials used in the car seat may deteriorate after a few years of service, meaning it won’t deliver the same protection as it was originally produced.
Your car seat does not turn out to be useless on the expiry date or if you use it beyond the expiration date. This means that you won’t be in trouble if you use an expired car seat. The car seat laws in the United States do not require the manufacturer to have this expiry date information on their car seats.
Instead, the laws require parents to use the car seat following the manufacturers’ instructions. While most car seat brands will do this – print the expiry date or tell the useful time and the DOM, to remind parents not to use an expired car seat.
It’s best for parents NOT to use an expired car seat.
Why Do Car Seats Expire?
Car seats expire due to various factors.
Mostly, the manufacturer has tested the seats for extreme cold and hot conditions to determine how long the lifespan of the seat is before it degrades and is still able to perform properly in a crash.
Secondly, like any new technology, car seat manufacturers are always improving their seats and want you to take advantage of any new safety advancements.
Like any new technology, car seat manufacturers are always working to improve their seats so that your child would get better protection.
As technology moves forward, older car seats without new technology will not be purchased by parents. They expire.
Recalls happen due to safety reasons. Manufacturers may find faulty in specific models. If the faulty cannot be fixed, they’ll recall the car seats. These recalls can be for any defect that is discovered over time, which will put your child at risk of injury or death.
If you have registered the car seat, you’ll receive the recall updates. So it’s recommended to register your purchase when you get it. The expiration dates help make sure that parents are using the most up-to-date car seat and are less likely to have recalls.
You can visit the recall list made by NHTSA to check if a car seat was recalled in the past 10 years.
Test Time Limits
The manufacturer has tested the seats for extreme cold and hot conditions to determine how long the lifespan of the seat is before it degrades. This ensures the longest serving time the car seat will provide and it is still able to perform properly in a crash.
Manufacturers test and give the expected useful time for their car seats – typically 8-10 years. That means this long lifespan is good enough to serve until your child does not need a car seat anymore before it expires.
Wear and tear
Just think about it: your child gets in and out of the car seat for years. It’s no doubt that the materials would degrade over time.
The plastic will become brittle and crack due to the heat and cold weather conditions throughout the years.
The metal will be rusty and not safe to use because of the rain and humidity.
The fabrics and padded foam wear and tear, or even disinform, for the hundreds of times in and out and long-term sitting.

What to Do with Your Graco Car Seat When It Expires

If you can’t wait for the Target Trade-in Event to open. You can donate the car seat to Child Passenger Safety Technicians, who are car seat experts and can use the expired car seat in their training classes to demonstrate the harness procedures and car seat installation.
