What to know
Graco's Landmark manual sets a 10-year useful life from the date of manufacture. Like the other 3-in-1 seats it moves from rear-facing to forward-facing with the harness and then to a highback booster.
The date of manufacture is on the seat itself. The date of manufacture is printed on a white label on the seat, typically on the back or bottom of the plastic shell (on infant seats, check the underside of the carrier and the base). The label shows the model number, serial number, and date of manufacture; most Graco seats do not print the expiration date itself.
Safety note: SeatCheck summarizes manufacturer and NHTSA guidance, but the label on your own seat and its manual are the final word. When in doubt, contact the manufacturer with your model and serial number.

Should I replace the Landmark 3-in-1 after a crash?
Graco is stricter than the federal minimum: it recommends replacing the car seat after any type of accident, even a minor one, and even if the child was not in the seat at the time. Graco's reasoning is that crash forces can cause internal structural damage you cannot see. Crash damage is not covered by warranty; Graco directs families to their auto insurance and will provide documentation stating the seat must be replaced.
