Wyoming lemon law

Verified against the statute / official state publicationWyo. Stat. §40-17-101

The short version

'Whichever is LATER' — Wyoming's window outlives most states'.
No written notice, no presumption (§40-17-101(h)).
Four attempts (the statute's 'more than three') or 30 business days.

The presumption — Wyoming's numbers

Presumption window	Wyoming's presumption window reads 'within the term of the express warranty or within one year following original delivery, whichever is LATER' — one of only two 'later of' windows in the country.
Same defect	4+ repair attempts
Days out of service	30+ business days — 30 or more BUSINESS days out of service.

The presumption is the set of numbers that shifts the burden to the manufacturer. A claim can exist outside the presumption — it is a shortcut, not the whole road. Read why.

The buyback — Wyoming's formula

Wyoming allows a reasonable allowance for the consumer's use with no published formula. This checker refuses to invent the number.

Notice and procedure

The presumption never applies unless the manufacturer received prior direct written notification and a reasonable opportunity to cure (§40-17-101(h)).

Dispute route: Exhaustion of a compliant manufacturer's dispute procedure is a precondition to the refund/replacement duty.

Attorney's fees: A consumer injured by a violation may recover reasonable attorney's fees (§40-17-101(j)).

Your deadline

Wyoming's statute prints no separate filing deadline; the warranty/1-year (whichever later) window and the exhaustion of the manufacturer's dispute procedure are the operative clocks.

Who and what is covered

New vehicles	Covered
Leased vehicles	Covered
Used vehicles	Covered in defined situations — see notes
Motorcycles	Covered in defined situations — see notes
RV / motor home	Covered — chassis / powertrain only

Motorcycle coverage is not resolved by the statute's text in our census — the checker scores motorcycles with that warning printed.
You must exhaust the manufacturer's informal dispute procedure first, where one exists in compliance with federal rules (§40-17-101(f)).
