CYBEX car seat expiration
CYBEX states the useful life of its seats as 6 years (cYBEX infant car seats — CYBEX's own phrasing is "this infant seat", stated on the Cloud G Lux product page; the Aton G owner's manual states the same six-year figure for that infant seat) · 8 years (cYBEX booster seats — CYBEX's own category-wide phrasing "CYBEX boosters", stated on the Solution G2 product page) · 10 years (the Sirona S convertible car seat — a model-specific statement on the Sirona S product page, not a statement about CYBEX convertibles generally) · 10 years (the Callisto G 360 rotating car seat — a model-specific statement in the General FAQ on the Callisto G 360 product page, not a statement about CYBEX rotating seats generally). The date of manufacture on your seat's label plus that figure is the expiration date.
CYBEX states no single brand-wide figure. Its Safety Center page gives only a range — the period of use "ranges from six years to ten years depending on the type and function of the car seat" — and the actual number is stated on each product page and printed on the seat itself. Across the US pages checked: infant seats 6 years, boosters 8 years, and the Sirona S and Callisto G 360 each 10 years, each stated by CYBEX for that seat or that category and kept scoped that way here. CYBEX uses two phrasings, "certified for X years from the date of manufacture" and "expires X years from date of manufacture", and both are listed as written. Every source here is CYBEX's US (en/us) storefront or a US-market manual; seats sold in other markets are not covered. For any CYBEX seat without a statement of its own, this page states no number — the label on the seat is authoritative.

Where the date is on a CYBEX seat
On a label on the bottom of the seat. On a CYBEX infant seat the date of manufacture is on the bottom of the carrier and also on the base. CYBEX repeats the same location by category on its product pages — the bottom of your CYBEX infant seat, the bottom of your CYBEX booster seat, the bottom of your Sirona S. CYBEX manuals also print an "Expires On" date on the child restraint and on the base, so the expiry can be read straight off the seat.
NEVER USE this Child Restraint when it is older than six (6) years. The date of manufacture can be found on a label affixed to the bottom of the Infant Car Seat, as well as on the Base.

Recalls and support
Check any CYBEX seat against NHTSA's recall lookup — the label's model number and date of manufacture are what the lookup asks for. Registering with CYBEX means they can contact you directly.
