Lemon Law in Wyoming
How many repair attempts and days out of service before Wyoming presumes your vehicle is a lemon, and whether used cars are covered.
presumption trigger (same defect)
Do I meet the Wyoming lemon presumption?
Enter your repairs and downtime. This checks the presumption; it is not a legal verdict.
This checklist is educational, not a legal verdict. Every state writes these numbers as a rebuttable presumption: hitting them shifts the burden to the manufacturer, and the manufacturer can still rebut it. Keep every repair order, send any required written notice, and consult a lawyer about your specific facts. This is legal information, not legal advice.
How the presumption works in Wyoming
The prongs that shift the burden to the manufacturer.
Wyoming states its attempt threshold as "more than three (3) times," which means a fourth repair of the same defect triggers the presumption, not the third. The 30 out-of-service days are BUSINESS days, and written notice to the manufacturer plus a chance to cure is a hard prerequisite before the presumption can be used.
Every state, Wyoming included, writes these thresholds as a rebuttable presumption. Reaching them shifts the burden onto the manufacturer to prove your vehicle is not a lemon; it does not mean you automatically win. You may also qualify with fewer attempts if a "reasonable number" of repairs is shown some other way, and the manufacturer can rebut the presumption. This is legal information, not legal advice.

What Wyoming car buyers get wrong
Wyoming’s lemon law is compact and built around a strict notice step, so read the prerequisites before you count repairs. Under Wyo. Stat. §40-17-101, the state presumes a lemon if, within one year after the vehicle is first delivered, the same nonconformity is repaired more than three times (that is, a fourth repair still leaves it broken) or the vehicle is out of service for a cumulative 30 business days. The count is phrased as "more than three," so the fourth attempt is what matters, and the 30 days are business days, which stretches the calendar downtime well past a month. The presumption cannot be raised against a manufacturer at all unless the consumer has first given direct written notice and a reasonable opportunity to cure, and if the manufacturer runs a qualifying arbitration program the consumer must go through it before the refund-or-replace remedy kicks in. The law reaches new vehicles under 10,000 pounds; there is no used-car lemon law. Meeting these numbers shifts the burden to the manufacturer rather than deciding the case outright.
Common questions
How many repair attempts is a lemon in Wyoming?
Wyoming presumes a lemon after more than three repairs of the same defect, meaning a fourth unsuccessful repair, or 30 business days out of service, within one year of delivery. It is a rebuttable presumption that shifts the burden to the manufacturer.
Are the 30 out-of-service days business or calendar days in Wyoming?
Business days. Weekends and holidays are excluded, so a cumulative total of 30 business days is meaningfully longer than 30 calendar days of downtime.
Do I have to notify the manufacturer before a Wyoming lemon claim?
Yes. The presumption does not apply against a manufacturer unless it first received direct written notice from or on behalf of the consumer and had a reasonable opportunity to cure the defect.
Does Wyoming’s lemon law cover leased or used cars?
The statute defines a covered consumer as someone who purchases the vehicle or receives it during the warranty term, and it does not extend the lemon law to lessees. It covers new vehicles only, with no separate used-car lemon law.
