When Do Car Seats Expire? And How Do You Know It?

It’s smart to keep your car up to date. From new tires to an oil change, when you maintain your car it helps you avoid unexpected breakdowns and costly repairs. However, did you know that your car seat could also expire? Well, it can. And while this may seem puzzling at first, given that nobody wants to set their kid up for danger in the event of a crash, or even worse, not be properly buckled down at all times. It is important now to know “When do car seats expire” for a suitable alternative.

Why Do Car Seats Expire?

Wear And Tear

Wear and tear Car Seats

The plastic shell that makes up the chair can become brittle over time, weather and easily break and crack on impact. For example, in the summer, car seats can be exposed to extreme heat causing them to become brittle and crack.

This can compromise the integrity of the seat’s structure, which could cause injury to your baby. If you’re not sure whether your car seat is expired or not, check the instructions for any warnings regarding expiration time or other signals of wear and tear.

Regulations change and standards

Car seat manufacturers must comply with new safety regulations every few years, which means they often have to make changes in their designs. These changes may require them to redesign their car seats completely and issue new versions that are compatible with new types of cars only — older models simply won’t fit well anymore.

Changing regulations and standards

In addition, baby passenger safety standards change from year to year as new research reveals better ways of protecting children during crashes or other accidents. To stay compliant with these standards, manufacturers must continue manufacturing new versions of each model every few years so they’re up-to-date with all relevant features.

Manufacturer Testing Has Its Limits

The tests for which a car seat was designed may not be representative of the way that a car seat will be used in an actual crash. For example, if a baby weighs more than 90 pounds (40 kilograms), most makers assume that he or she will be using only the cars’ lap belt, but few kids actually ride this way.

Manufacturer testing has its limits

The same goes for when children are in booster seats after age 12 when most manufacturers assume they will still be using only the vehicle’s lap belt. But many kids continue to use boosters well past age 12 — and those who do should be using both the vehicle lap belt and shoulder belt until they’re 4 feet 9 inches (1.45 meters) tall.


Because of recalls, car seats are also known to degrade with time. Recalls are issued by manufacturers when they find out that their products have safety defects that need to be fixed immediately before someone gets hurt or killed because of them. 

Recalls Car Seats

Recalls can occur at any time during a product’s life cycle — even after production has stopped and it’s no longer being sold as new stock — so it’s important to check if your car seat has been recalled before using it again.

If you have an older baby, you may be wondering when to get a new car seat. The answer depends on the type of car seat, but your child’s safety is always a top priority.

According to government requirements, when seats expire, car seats must be replaced every six years. That doesn’t mean they become unsafe in that time span. But it does indicate that makers expect their products to last for no more than six years.

If you’re unsure how old your car seat is or how long it has been since it was installed in your car, check the manufacture date on the sticker. The National Highway Traffic Safety Administration (NHTSA) should be contacted if one does not already exist.

Where To Find The Expiration Dates On Popular Brands?

This recommendation is made by the National Highway Traffic Safety Administration (NHTSA) after six years of usage. This helps ensure that the car seat has plenty of life left in it and can still protect your baby properly if he or she were to be in an accident.

However, many people choose to alternative their car seats before this time because they’re concerned about safety issues such as cracks in plastic or metal components or missing nuts and screws.

If you just purchased a used car seat from someone else or if you bought one secondhand and aren’t sure how old it is, take it to your local fire station or police station and have them inspect it for free. They’ll tell you whether or not it’s safe to use and let you know if there are any problems with the straps or buckles.


Can You Use A Car Seat Expired?

Sure. However, for most products, the expiration date is there for a reason. There is a risk that the product may no longer be safe. It’s a warning.

For instance, if you buy a car seat that expires in two years and then use it for five years, the plastic may become brittle or break more easily than a newer seat. This could make it less safe in an accident, especially if it cracks during use.

The Way You Can Find The Expire Date’s Car Seat
