Wyoming Lemon Law: Your Rights to Replacement or Refund

The Wyoming lemon law, found at Wyo. Stat. § 40-17-101, gives you the right to a replacement vehicle or a full refund if the manufacturer cannot fix a serious defect in your new vehicle after a reasonable number of tries within the first year.¹ The statute spells out exactly how many repair attempts or days out of service count, and it requires one step most owners skip: direct written notice to the manufacturer before you can rely on those thresholds.

Which Vehicles and Buyers Are Covered

The law applies to any self-propelled vehicle with an unladen weight under 10,000 pounds that was sold or registered in Wyoming and carries a manufacturer’s express warranty.¹ Wyoming measures the cutoff by unladen weight (the vehicle’s weight without cargo or passengers), not gross vehicle weight rating. Heavy-duty pickups and commercial trucks above that weight fall outside the statute. Vehicles moved only by human power are excluded by the statute’s language.

You qualify as a “consumer” if you bought the vehicle new (not for resale), received it as a transfer while the warranty was still in effect, or otherwise have the right under the warranty’s terms to enforce it.¹ A second owner can use the law as long as the factory warranty hasn’t expired. Used vehicles sold after the original warranty ends generally fall outside this statute, because the protections are tied to the manufacturer’s express warranty on a new vehicle.

When Your Vehicle Legally Becomes a Lemon

A vehicle qualifies when a defect substantially impairs both its use and its fair market value, and the manufacturer has had a reasonable number of chances to fix the problem. Wyoming law creates a legal presumption that enough attempts have been made when either of two triggers is met within one year of the original delivery date.

The first trigger is repair frequency. The same defect must have been subject to repair more than three times, with the problem still present.¹ Read that carefully. “More than three” means the fourth visit for the identical issue is the one that crosses the line. Three trips to the shop for the same problem, on their own, do not get you there. This is the single most common place consumers miscount.

The second trigger is cumulative downtime. The vehicle has been out of service for repairs for a total of 30 or more business days within the first year.¹ Those days don’t need to run back-to-back. Several shorter stays that add up to 30 business days count. Weekends and holidays don’t.

The Written Notice You Have to Send

Hitting a trigger isn’t enough on its own. The presumption that the manufacturer has had a reasonable number of repair attempts does not apply unless the manufacturer has received prior written notification from you (or someone acting on your behalf) and has had a reasonable opportunity to cure the defect.¹ Dropping the car at the dealer again is not notice. It has to go to the manufacturer, in writing.

Your letter should include the vehicle identification number, a description of the defect, a dated summary of every repair attempt, and a clear request for a replacement or refund. Send it to the manufacturer’s customer relations address, which appears in the warranty booklet. Use certified mail with a return receipt so you can prove when it arrived. That delivery date starts the manufacturer’s final opportunity to fix the problem.

Replacement or Refund: What You Can Collect

Once the thresholds are met and written notice has been given, the manufacturer must either replace your vehicle or buy it back.¹ The choice between the two belongs to the manufacturer, not you.

A replacement has to be a new or comparable vehicle of the same type with similar equipment. A refund has to cover the full purchase price plus all collateral charges, which typically includes sales tax, registration fees, and finance charges. If you still owe on a loan, the refund goes to the lienholder up to the amount of their interest, so the manufacturer pays off that balance as part of the buyback.¹

The Deduction for Your Use

The manufacturer gets to subtract a reasonable allowance for consumer’s use from your refund. Wyoming defines this as the value of the use you got from the vehicle before you first reported the defect, plus any later periods when the vehicle was not in the shop.¹ The statute doesn’t lock in a mileage formula. The practical takeaway is simple: report the defect early. The sooner your first complaint is on the record, the smaller the deduction.

Negative Equity From a Trade-In

If you rolled unpaid debt from a previous vehicle into the loan on the lemon, that rolled-over balance is a separate issue. The manufacturer’s buyback obligation runs to the purchase price and collateral charges of the vehicle in question. Manufacturers routinely argue they shouldn’t have to absorb the portion of your loan that represents a prior vehicle. A buyback may not fully clear your loan in that situation, and you could still owe the rolled-over amount after the vehicle is returned.

The Informal Dispute Step Before Court

Wyoming law requires you to use the manufacturer’s informal dispute settlement procedure before filing suit, but only if the manufacturer runs one that complies with the federal rules in 16 C.F.R. Part 703.¹ If there is no such program, or it fails the federal standards, you can skip this step and go straight to court.

Those federal rules put real limits on the process. The program can’t charge you a fee, and the decision-makers must be independent of the manufacturer. On panels of three or more, at least two-thirds must have no involvement in making, selling, or servicing vehicles. The program must issue a decision within 40 days of receiving your dispute.² Many major manufacturers use the BBB AUTO LINE program, which handles disputes at no cost to owners.³ Check your warranty booklet to see whether your manufacturer participates and whether that participation covers Wyoming.

Filing a Lawsuit

If the informal process doesn’t resolve the dispute, or no compliant program exists, you can bring a civil action. The statute allows any consumer injured by a violation to sue and recover reasonable attorney’s fees from the manufacturer.¹ That fee-shifting provision matters: many lemon law attorneys will take cases on contingency because the manufacturer pays the fees if you win.

The statute doesn’t set its own deadline for filing. Don’t wait to see how long you can push it. Repair records get lost, dealership service departments cycle through retention schedules, and witnesses move on. File promptly after the informal process ends or after the manufacturer rejects your demand.

The Federal Backstop: Magnuson-Moss

If your situation doesn’t quite hit Wyoming’s specific triggers, federal law may still give you a route. The Magnuson-Moss Warranty Act applies to any product sold with a written warranty and lets consumers sue manufacturers who fail to honor warranty obligations.⁴ Your individual claim must be worth at least $25, and a prevailing consumer can recover attorney’s fees and court costs.

The federal act has its own exhaustion requirement. If the manufacturer has incorporated a compliant informal dispute procedure into the warranty, you must use that procedure before suing in federal court.⁴ It’s the same BBB AUTO LINE or similar program, so going through it once satisfies both state and federal rules. Magnuson-Moss is especially useful when the defect is serious but the repair count or downtime hasn’t yet reached Wyoming’s statutory numbers, because the federal standard focuses on whether the manufacturer failed to honor the warranty rather than counting visits.

Documentation That Decides the Case

Successful lemon law claims live and die on paperwork. Start collecting records from the first repair visit, not the fourth.

Get a copy of the repair order every time the vehicle enters a shop. Each one should show the date in, date out, the complaint as you described it, and what the technician did. If the dealer hands you a vague summary, ask for the detailed work order.
Record the odometer reading at every visit. Mileage affects the use-allowance deduction, and the lower your mileage at the first defect report, the less the manufacturer can subtract from your refund.
Save every email, letter, and text with the dealer or manufacturer. After phone calls, send a short email summarizing what was discussed so there’s a written record.
Keep your certified notice letter and the return receipt. Without proof the manufacturer received direct written notification, the statutory presumption doesn’t apply, and the whole structure of your claim leans on it.

Line the records up chronologically before you contact an attorney or file for arbitration. A clean, dated file lets anyone reviewing the claim see at a glance that the thresholds have been met and the notice step was done right.
