Wyoming lemon law: the single-statute framework under W.S. §40-17-101, the one-year claim window, the 10,000-pound unladen weight cap, and the more-than-three-attempts presumption
Wyoming's lemon law is among the most compact in the United States. While many states spread their lemon law across a dozen or more statute sections with detailed definitions, arbitration procedures, and remedy schedules, Wyoming fits nearly its entire framework into a single section: W.S. §40-17-101 (Definitions; express warranties; duty to make warranty repairs).
The brevity has consequences. Wyoming's framework provides the core lemon law protections (a repair-attempt presumption, a substantial impairment standard, and a refund-or-replacement remedy) but without many of the consumer-friendly features that more developed state frameworks include. There is no dedicated state arbitration board, no detailed used-vehicle provision, and a relatively short one-year claim window.
For Wyoming consumers, understanding the framework's specific thresholds (and its distinctive 10,000-pound unladen weight cap) is essential, because the statute does not provide the procedural scaffolding that consumers in other states can rely on.
What vehicles qualify under Wyoming's lemon law?
Wyoming's lemon law under W.S. §40-17-101 covers new motor vehicles sold or registered in Wyoming with an unladen weight under 10,000 pounds. Coverage extends to original purchasers, transferees who acquire the vehicle during the warranty period, and anyone entitled to enforce an express warranty. The unladen weight standard differs from most states' gross vehicle weight rating measurement.
Per W.S. §40-17-101, the Wyoming lemon law covers any motor vehicle sold or registered in Wyoming with an unladen weight of under 10,000 pounds.
The "unladen weight" standard is distinctive. Most state lemon laws use gross vehicle weight rating (GVWR), which includes the vehicle's maximum loaded weight. Wyoming uses unladen weight, which is the weight of the empty vehicle. The 10,000-pound unladen weight cap is also lower than many states' GVWR caps (Montana uses 15,000 pounds GVWR, South Dakota uses similar). The combination means Wyoming's coverage is measured differently and capped at a lower figure than most states, which can exclude heavier trucks and larger vehicles.
The vehicle must be new and covered under an express warranty. The "consumer" definition under §40-17-101(a)(i) includes:
A person who purchases a motor vehicle, other than for resale, to which an express warranty applies.
A person to whom a motor vehicle is transferred during the term of an applicable express warranty.
A person entitled by the terms of an express warranty to enforce it.
The transferee provision is consumer-friendly: it extends the lemon law protection to subsequent owners who acquire the vehicle while the manufacturer's warranty is still in effect. A person who buys a used car that is still under the original manufacturer's warranty may have Wyoming lemon law protection through this provision.
How long do you have to file a Wyoming lemon law claim?
Wyoming gives consumers one year from original delivery to report a qualifying defect and begin repair attempts under the lemon law. This window is shorter than many states, which allow two years or tie the period to the warranty term. If repairs are ongoing when the year expires, the manufacturer must still complete them.
The Wyoming lemon law presumption applies to defects that arise and are subject to repair within one year following the original delivery of the motor vehicle to the consumer.
The one-year window is short. Many states use two years (Montana), and some tie the period to the warranty term. Wyoming's one-year window means the qualifying defect must first appear and the repair attempts must occur within the first year of ownership.
Importantly, the statute provides that repairs must be completed even if the one-year window passes during the repair process. If the consumer reports the nonconformity within the one year, the manufacturer's obligation to repair continues even after the year expires while the repairs are being completed. This protects consumers whose defects are reported in time but whose repairs extend beyond the one-year mark.
How many repair attempts does Wyoming's lemon law require?
Wyoming's lemon law presumption arises when the same defect has been subject to repair more than three times (functionally a fourth attempt) and still persists, or when the vehicle has been out of service for a cumulative 30 business days within one year of delivery. This places Wyoming among four-attempt states.
Per W.S. §40-17-101(d), it is presumed that a reasonable number of attempts have been undertaken to conform the vehicle to the express warranty if, within one year following original delivery:
The same nonconformity has been subject to repair more than three times by the manufacturer, its agents, or its authorized dealers, and the same nonconformity continues to exist; OR
The vehicle is out of service due to repair for a cumulative total of 30 business days.
The "more than three times" language is worth parsing. Read literally, the presumption arises after the same defect has been repaired more than three times, which means a fourth repair attempt with the defect still present.
The 30 business day out-of-service threshold is consumer-favorable in calendar terms (business days exclude weekends and holidays, so 30 business days is more than six calendar weeks).
What counts as substantial impairment under Wyoming's lemon law?
Under Wyoming's lemon law, the defect must substantially impair both the use and the fair market value of the vehicle. This conjunctive standard requires the consumer to demonstrate impact on both elements. Wyoming does not provide a separate single-attempt qualification for serious safety defects, unlike some other states.
The defect must "substantially impair the use and fair market value" of the motor vehicle to the consumer. Wyoming uses the conjunctive "use and fair market value" framing (the defect must affect both), rather than a disjunctive "use, value, or safety" standard. There is no separate safety threshold; Wyoming does not have the single-attempt safety qualification that West Virginia and Idaho provide for serious safety defects.
Is prior written notice to the manufacturer required?
Yes. Before the lemon law presumption applies, Wyoming consumers must send direct written notice to the manufacturer and provide a reasonable opportunity to cure the defect. Notice to the dealer alone is insufficient. The standard practice is certified mail with return receipt, identifying the vehicle, the defect, and prior repair attempts.
The presumption does not apply against a manufacturer unless the manufacturer has received prior direct written notification from or on behalf of the consumer, and has had a reasonable opportunity to cure the alleged defect.
This is a procedural requirement common to most state lemon laws, but it is strictly applied. The consumer must send written notice directly to the manufacturer (not merely to the dealer) and give the manufacturer a final chance to fix the defect before the lemon law presumption attaches. The standard practice is to send the notice by certified mail with return receipt, identifying the vehicle, describing the defect, and listing the repair attempts to date.
Do you have to use the manufacturer's dispute settlement procedure in Wyoming?
Yes. Wyoming requires consumers to exhaust any qualifying informal dispute settlement procedure operated by the manufacturer before pursuing the statutory refund or replacement remedy. The procedure must comply with 16 C.F.R. Part 703. Most major manufacturers operate such programs, making this a common prerequisite for Wyoming lemon law claims.
Per W.S. §40-17-101, the refund-or-replacement provision in subsection (c) does not apply to a consumer who has failed to exhaust their remedies under a manufacturer's informal dispute settlement procedure (IDSP), if such a procedure exists and complies with the applicable federal statute and regulation (16 C.F.R. Part 703).
If the manufacturer operates a qualifying IDSP (such as a BBB AUTO LINE arbitration program), the consumer must use it before pursuing the statutory refund-or-replacement remedy. Most major manufacturers operate IDSPs, so this is a practical first step for most Wyoming claims.
What remedies does Wyoming's lemon law provide?
When a manufacturer cannot conform a vehicle to its express warranty after a reasonable number of attempts, Wyoming law requires the manufacturer to either replace the vehicle with a comparable new model or refund the full purchase price plus collateral charges, minus a reasonable use allowance. The manufacturer, not the consumer, chooses between the two options.
Per W.S. §40-17-101(c), if the manufacturer is unable to conform the vehicle to the express warranty after a reasonable number of attempts, the manufacturer shall:
Replace the motor vehicle with a new or comparable motor vehicle of the same type and similarly equipped; OR
Accept return of the motor vehicle and refund to the consumer and any lienholder the full purchase price including all collateral charges, less a reasonable allowance for the consumer's use.
The structure gives the manufacturer the election between replacement and refund. The refund includes the full purchase price plus collateral charges (sales tax, registration, license fees), reduced by a reasonable allowance for the consumer's use (a mileage-based offset).
Does Wyoming's lemon law preserve other consumer remedies?
Yes. W.S. §40-17-101(e) explicitly provides that the lemon law does not limit any other consumer rights or remedies. Wyoming consumers can pursue the lemon law alongside federal Magnuson-Moss Warranty Act claims and UCC remedies simultaneously, without being forced to elect one path over another.
A distinctive and consumer-friendly feature: W.S. §40-17-101(e) provides that "nothing in this section shall be construed to limit the rights or remedies of a consumer under any other statute."
This preserves the consumer's other remedies. Unlike New Mexico, which forces an election between the lemon law and the UCC remedies, Wyoming explicitly preserves all other consumer remedies. A Wyoming consumer can pursue the lemon law alongside the federal Magnuson-Moss Warranty Act and the Wyoming UCC without being forced to choose. This is the more consumer-favorable approach.
Can you recover attorney's fees under Wyoming's lemon law?
Yes. Wyoming provides for recovery of attorney's fees by a prevailing consumer in a lemon law case. Combined with Magnuson-Moss fee-shifting on a parallel federal claim, this makes it economically practical for Wyoming consumers to retain professional legal representation for their lemon law disputes.
Wyoming provides for the recovery of attorney's fees by a prevailing consumer, and in most cases the manufacturer is responsible for paying the consumer's legal fees. Combined with the Magnuson-Moss fee-shifting (which applies to the federal claim filed alongside the state claim), this makes professional representation economically viable for Wyoming consumers.
What does Wyoming's lemon law exclude?
Wyoming's lemon law does not cover defects caused by consumer abuse, neglect, or unauthorized modifications or alterations of the vehicle. These standard exclusions allow a manufacturer to defend a lemon law claim by demonstrating that the defect resulted from the consumer's own conduct rather than a manufacturing defect or nonconformity.
The Wyoming lemon law does not cover defects caused by consumer abuse, neglect, or unauthorized modifications or alterations of the vehicle. These are the standard exclusions; a manufacturer can defend a claim by showing the defect resulted from the consumer's own conduct rather than a manufacturing nonconformity.
How does Wyoming's lemon law compare to other states?
Wyoming's single-statute lemon law is among the most compact in the country. It lacks dedicated arbitration boards, detailed remedy schedules, and used-vehicle provisions found in more developed states. Notable features include a four-attempt repair threshold, a short one-year claim window, a distinctive unladen weight cap, and preserved parallel remedies.
| Feature | Wyoming's Approach | Consumer Impact |
|---|---|---|
| Statute structure | Single section (W.S. §40-17-101) | Among the most bare-bones; lacks dedicated arbitration boards, detailed remedy schedules, and used-vehicle provisions |
| Repair-attempt threshold | "More than three times" (functionally four attempts) | Among four-attempt states |
| Claim window | One year from original delivery | Short; many states use two years |
| Weight cap | 10,000 pounds unladen weight | Distinctive (most states use GVWR) and on the lower side |
| Out-of-service threshold | 30 business days | Consumer-favorable in calendar terms |
| Impairment standard | Conjunctive "use and fair market value," no separate safety threshold | Slightly less consumer-favorable than disjunctive standards |
| Remedy election | Manufacturer chooses between replacement and refund | Less consumer-favorable than consumer-choice states |
| Preservation of other remedies | All other remedies preserved (no forced election) | Consumer-favorable; contrasts with New Mexico's election-of-remedies rule |
| Additional protections | Transferee coverage and attorney's fee recovery | Consumer-favorable |
What steps should you take for a Wyoming lemon law claim?
Wyoming consumers should act within the one-year claim window, document all repair attempts with dated repair orders, confirm vehicle eligibility under the 10,000-pound unladen weight cap, send certified written notice directly to the manufacturer, exhaust any manufacturer IDSP, and consider filing parallel federal Magnuson-Moss claims to maximize available remedies.
For Wyoming consumers with a potential lemon law claim:
Track the one-year claim window carefully. The qualifying defect must first appear and the repair attempts must occur within one year of delivery. The window is shorter than many states; act promptly.
Document the repair attempts. The "more than three times" threshold requires the same defect to be repaired more than three times (a fourth attempt) with the defect continuing. Dated repair orders describing the specific defect are the foundation.
Confirm your vehicle is under the 10,000-pound unladen weight cap. The distinctive unladen weight standard (not GVWR) and the lower cap can exclude heavier vehicles.
Send written notice to the manufacturer by certified mail. The prior written notice and opportunity to cure are required before the presumption applies. Notice to the dealer alone is not sufficient; the manufacturer must receive direct written notice.
Use the manufacturer's IDSP first if one applies. The refund-or-replacement remedy is unavailable to a consumer who has not exhausted a qualifying IDSP. Most major manufacturers operate one.
Take advantage of the preserved remedies. Because Wyoming preserves all other consumer remedies, you can pursue the lemon law alongside the federal Magnuson-Moss claim and the UCC without being forced to elect. File the Magnuson-Moss claim alongside the state claim to capture the federal fee-shifting.
For the transferee provision, confirm whether the vehicle is still under the original manufacturer's warranty. If you acquired a vehicle while the warranty was in effect, you may have Wyoming lemon law protection as a transferee.
The Wyoming framework is minimal but functional. The single-statute structure provides the core protections without the procedural scaffolding of more developed states. The short one-year window, the "more than three times" threshold, and the distinctive unladen weight cap are the framework's defining features; the preservation of other remedies and the attorney's fee provision are its consumer-favorable elements. Wyoming consumers who document their cases and follow the notice and IDSP requirements have a workable path to remedy, but should be aware that the framework offers less procedural support than most states.
