If the manufacturer asks for one more repair after your notice, take the car in and get a repair order.
Ask for a refund or replacement, use arbitration, or call a lawyer
If your manufacturer has a dispute program that meets the state’s rules (check your warranty booklet), you may have to use it first. See the Arbitration section below. If you win, the court can make the manufacturer pay your lawyer (see What you can get), so many lemon law lawyers charge nothing up front.

When a car is a lemon in Wyoming

Within 1 year of delivery, your vehicle is presumed a lemon if the same defect has been repaired more than 3 times (so at least 4) and still exists, or the vehicle has been out of service for repairs a total of 30 business days. The defect must substantially impair both the use and the fair market value of the vehicle. The presumption applies only after the manufacturer received direct written notice from you and had a reasonable chance to fix it.

Period: 1 year from the original delivery to you. You must report the defect within that year; repairs must still be made after the year ends.

Notice to the manufacturer

Send the manufacturer direct written notice of the defect and give it a reasonable opportunity to fix it. Without this, the presumption does not apply (Wyo. Stat. § 40-17-101(h)).

Arbitration

Maybe — check your warranty booklet for an arbitration program (e.g. BBB AUTO LINE). If the manufacturer has an informal dispute program that complies with federal rules, you must use it before you can get a refund or replacement under the lemon law. Wyoming has no state-run lemon-law arbitration.

What you can get

A new or comparable replacement vehicle of the same type and similarly equipped, or a refund of the full purchase price including all collateral charges, minus a reasonable allowance for your use. The allowance covers use before you first reported the defect and any later time the vehicle was not out of service for repair. Refunds are split between you and any lienholder.

Attorney fees: Yes, a consumer may recover reasonable attorney fees from the manufacturer that issued the warranty (Wyo. Stat. § 40-17-101(k)).

Free lemon law notice letter

Most states require you to tell the manufacturer in writing and give it a last chance to fix the car. Fill this in, download the letter, sign it and mail it to the manufacturer. Keep a copy.

Send it by certified mail with return receipt so you have proof, and keep the receipt.
