Wyoming Lemon Law: Your Complete Legal Guide

What Vehicles Are Covered
Wyoming's lemon law covers a range of vehicles meeting specific criteria.
Covered Vehicle Types
- New motor vehicles: Self-propelled vehicles under 10,000 pounds unladen weight
- Vehicles sold in Wyoming: Purchased from dealers within the state
- Vehicles registered in Wyoming: Including vehicles purchased elsewhere but registered in Wyoming
- Passenger cars: Sedans, coupes, hatchbacks, and similar vehicles
- Trucks: Light-duty trucks meeting the weight requirement
- SUVs and crossovers: Under the 10,000 lb. unladen weight limit
- Vans: Including minivans for personal use
Vehicles NOT Covered
- Vehicles moved solely by human power
- Motor vehicles with an unladen weight of 10,000 pounds or more
- Used vehicles (vehicles previously titled to a consumer)
- Vehicles purchased primarily for resale
Key Definitions
Consumer: Wyoming defines a consumer as any person who:
- Purchases a motor vehicle (other than for resale) to which an express warranty applies, OR
- To whom a motor vehicle is transferred during the term of an express warranty, OR
- Is entitled by the warranty terms to enforce it
Express Warranty: The written warranty, so labeled, of the manufacturer of a new motor vehicle, including any terms or conditions precedent to enforcement.

Wyoming's Lemon Law Presumption
Wyoming law creates a presumption that a reasonable number of repair attempts have been made when certain conditions are met within one year following the original delivery of the motor vehicle to the consumer.
The Lemon Law Presumption Applies When:
| Condition | Requirement | Details |
|---|---|---|
| Repair Attempts (Same Problem) | More than 3 times | Same nonconformity subject to repair and continues to exist |
| Days Out of Service | 30 or more cumulative BUSINESS days | Vehicle out of service due to repair (note: business days, not calendar days) |
| Coverage Period | 1 year following original delivery | From date of first delivery to the consumer |
Important: Wyoming counts business days rather than calendar days for the out of service calculation. This means weekends and holidays are typically not counted, effectively requiring more total time out of service before the presumption applies.
Prior Written Notice Requirement
The presumption does not apply against a manufacturer unless:
- The manufacturer has received prior direct written notification from or on behalf of the consumer
- The manufacturer has had a reasonable opportunity to cure the alleged defect
What Qualifies as a "Nonconformity"?
While Wyoming's statute does not provide an explicit definition, nonconformity generally refers to any defect or condition that:
- Does not conform to the applicable express warranties
- Substantially impairs the use and fair market value of the motor vehicle
Consumer Remedies: Refund vs. Replacement
When a vehicle qualifies as a lemon under Wyoming law, the consumer has the right to choose between a replacement vehicle or a full refund.
Option 1: Replacement Vehicle
The manufacturer must provide:
- A new or comparable motor vehicle of the same type
- Similarly equipped to the original vehicle
Option 2: Full Refund
The manufacturer must provide:
- Full purchase price: The complete amount paid for the vehicle
- All collateral charges: Fees and charges associated with the purchase
Refunds are made to the consumer and any lienholder, as their interests may appear.
Usage Deduction: The manufacturer may deduct a "reasonable allowance for consumer's use." This is defined as the amount directly attributable to use of the motor vehicle:
- Prior to the first report of the nonconformity to the manufacturer, agent, or dealer, AND
- During any subsequent period when the motor vehicle is NOT out of service due to repair
Unlike many states, Wyoming does not specify a formula for calculating this allowance (such as a per-mile calculation). The allowance must simply be "reasonable."

How to File a Lemon Law Claim in Wyoming
Filing a successful lemon law claim in Wyoming requires careful documentation and compliance with notice requirements.
Step 1: Document Everything
- Keep all repair orders and invoices
- Record the dates your vehicle was in the shop (tracking business days)
- Document the symptoms you experienced
- Save all correspondence with the dealer and manufacturer
- Take photos or videos of defects when possible
Step 2: Report the Nonconformity
Report the problem to the manufacturer, its agent, or its authorized dealer within one year following the original delivery of the motor vehicle to you. This triggers the manufacturer's obligation to make necessary repairs.
Step 3: Allow Repair Attempts
Give the manufacturer, its agents, or authorized dealers the opportunity to repair the nonconformity. The manufacturer's repair obligation extends even if the one-year period has expired, as long as the nonconformity was first reported within that period.
Step 4: Provide Written Notice to Manufacturer
Before the presumption can apply, you must provide prior direct written notification to the manufacturer and give them a reasonable opportunity to cure the defect.
Step 5: Check for Informal Dispute Settlement Procedure
If the manufacturer has an informal dispute settlement procedure that complies with applicable federal statute and regulation, you must exhaust that remedy before filing suit.
Step 6: Consider Civil Action
If remedies are not satisfactorily provided, you may bring a civil action to enforce the lemon law.
Written Notice Requirements
Wyoming's lemon law places significant importance on written notice to the manufacturer.
Notice Requirements
The presumption of reasonable repair attempts does not apply unless:
- The manufacturer has received prior direct written notification from or on behalf of the consumer
- The manufacturer has had a reasonable opportunity to cure the alleged defect
Content of Notice
While the statute does not specify exact contents, effective written notice should include:
- Consumer's name and contact information
- Vehicle identification (year, make, model, VIN)
- Description of the nonconformity
- History of repair attempts
- Request for remedy
Method of Delivery
While the statute does not specify a delivery method, consumers should use certified mail or another method providing proof of receipt to document that the manufacturer received the notice.

Informal Dispute Settlement Procedures
Wyoming's lemon law incorporates informal dispute settlement procedures by reference to federal requirements.
When Required
The lemon law presumption provisions do not apply to any consumer who has failed to exhaust remedies under a manufacturer's informal dispute settlement procedure if:
- Such a procedure exists, AND
- The procedure is in compliance with applicable federal statute and regulation (Magnuson-Moss Warranty Act and 16 CFR Part 703)
FTC Requirements
To be valid, manufacturer dispute settlement procedures must meet federal standards including:
- Independence from manufacturer control in decision-making
- Adequate record-keeping and reporting
- Timely resolution of disputes
- No charge to consumers beyond shipping costs
- Decisions not binding on consumers (consumers may still pursue court action)
Manufacturer Defenses
Wyoming provides manufacturers with specific affirmative defenses against lemon law claims.
| Defense | Manufacturer's Argument | Consumer's Counter |
|---|---|---|
| No substantial impairment | Alleged nonconformity does not substantially impair use and fair market value | Document how defect affects daily use and resale value |
| Abuse or neglect | Nonconformity resulted from consumer abuse or neglect | Provide maintenance records showing proper care |
| Unauthorized modification | Nonconformity resulted from unauthorized modification or alteration | Show defect existed before modifications or is unrelated |
| No written notice | Manufacturer did not receive prior written notification | Provide proof of notice delivery (certified mail receipt) |
Extensions to Time Periods
Wyoming's lemon law includes provisions for extending time periods under certain circumstances.
Grounds for Extension
Any period of time provided in the lemon law presumption section may be extended by any period of time during which the vehicle could not reasonably be repaired due to:
- War
- Invasion
- Act of terror
- Civil unrest
- Strike
- Fire
- Flood
- Natural disaster
This provision ensures that consumers are not penalized when external circumstances beyond anyone's control delay repairs.
Other Remedies Available
Wyoming's lemon law explicitly preserves consumers' rights under other laws.
Preservation of Other Rights
The statute states that nothing in the lemon law shall be construed to limit the rights or remedies which are otherwise available to a consumer under any other statute. This means consumers may also pursue:
- Federal Magnuson-Moss Warranty Act claims: The federal lemon law may provide additional remedies
- Breach of warranty claims: Under the Uniform Commercial Code
- Consumer protection claims: Under Wyoming's consumer protection statutes
- Common law claims: Such as fraud or misrepresentation
Attorney Fees
Any consumer injured by a violation of Wyoming's lemon law may bring a civil action to enforce the law and may recover reasonable attorney's fees from the manufacturer who issued the express warranty.
