The Wyoming lemon law in detail

Wyoming’s lemon law, section 40-17-101 of the Wyoming Statutes, read in the title published by the legislature on November 1, 2026, protects a new motor vehicle for one year from delivery. The defect must be reported in that year. The text speaks of a defect repaired “more than three times”, so the fourth attempt meets the test; the other route is 30 business days out of service. If the manufacturer has an informal dispute procedure that complies with the federal rules, the owner must exhaust it before suing. The section sets no separate filing deadline that we could find; other Wyoming time limits on warranty claims may apply. Keep the repair orders: they are the only record of the count.

A short Wyoming statute

Wyoming’s whole lemon law fits in one section, and it leaves much to the warranty and to the manufacturer’s procedure. The one-year period has no mileage limit, which helps owners who drive long distances.

Because the procedure must be exhausted first, the 40-day decision rule of the federal regulation matters in Wyoming: a program that does not decide in time cannot hold up the claim. The title is linked below as a PDF from the legislature.

Questions people ask

How many repair attempts make a car a lemon in Wyoming?

The Wyoming presumption starts at 4 attempts on the same defect, or 30 business days out of service in total, within 1 year. Meeting a test creates a presumption, which the manufacturer can still contest before the program or the court. Count each visit with its repair order, and keep every order with its dates.

Does the Wyoming lemon law cover used or leased cars?

New motor vehicles. Used cars: Not covered. A used car sold with the rest of the manufacturer’s warranty still carries that warranty, which federal law enforces even where the state lemon law stops. Leases are covered where the text names lessees.

Must I go through arbitration before suing under the Wyoming lemon law?

A manufacturer informal dispute procedure that complies with federal rules must be exhausted first (§ 40-17-101(f)). Under the federal rule, 16 CFR Part 703, a manufacturer program that a warranty requires you to use first must decide within 40 days, and its decision does not bind you if you go to court afterwards. The warranty booklet names any program the manufacturer offers.
