Colorado Lemon Law Guide: Your Rights Under Colorado Lemon Law
What Is the Colorado Lemon Law?
The Colorado Lemon Law, officially found in the Colorado Revised Statutes (C.R.S.A. §§ 42-10-101 through 42-10-110), is a consumer protection statute designed to shield buyers and lessees from being stuck with defective vehicles. Often referred to as the Motor Vehicle Warranties Act, this law requires manufacturers to repair, replace, or refund a vehicle if it fails to conform to its express warranty after a reasonable number of repair attempts.
The law protects consumers who purchase or lease a motor vehicle normally used for personal, family, or household purposes. Notably, recent amendments in 2024 expanded the law to include motor vehicles used by small businesses for both business and personal purposes. The Colorado Attorney General's Office, led by Attorney General Phil Weiser, actively enforces consumer protection laws and provides resources for consumers dealing with defective vehicles. Consumers can file complaints and find additional guidance through the Attorney General's StopFraudColorado.gov portal.
Which Vehicles Qualify Under the Colorado Motor Vehicle Warranties Act?
To qualify for protection under the Colorado Lemon Law, a vehicle must meet specific criteria regarding its type, use, and the timing of the defects.
New vs. Used Vehicle Coverage
The Colorado Lemon Law primarily covers new motor vehicles. However, the law also provides specific protections for consumers purchasing used "lemon buyback" vehicles. Dealers selling these vehicles must affix a "Lemon Law Buyback" decal and note it on the vehicle's title. Additionally, dealers must allow a third-party inspection or provide a seven-day free-look period for buyers of these buyback vehicles. While standard used cars are generally not covered under the state lemon law unless they are still under the manufacturer's original warranty, consumers may still have rights under the federal Magnuson-Moss Warranty Act.
Leased Vehicle Coverage
Yes, leased vehicles are covered under the Colorado Lemon Law. The statute defines a consumer to include anyone to whom the motor vehicle is transferred during the duration of the manufacturer's express warranty, which encompasses lessees.
Mileage and Time Limitations
Under the updated 2024 law, the duration of lemon law protections extends to two years after the original delivery date of the vehicle to the consumer or within the first 24,000 miles of operation, whichever occurs earlier. This is a significant expansion from the previous limit of one year or the warranty period.
Vehicle Types Covered
The law covers self-propelled private passenger vehicles, including pickup trucks and vans, designed primarily for travel on public highways and used to carry not more than ten persons. It explicitly excludes motor homes and vehicles designed to travel on three or fewer wheels (such as motorcycles).
What Qualifies as a "Lemon" in Colorado?
A vehicle is presumed to be a lemon in Colorado if it has a nonconformity—a defect or condition that substantially impairs its use, market value, or safety—that the manufacturer cannot fix after a reasonable number of attempts.
Number of Repair Attempts Required
The 2024 amendments lowered the threshold for what constitutes a "reasonable number of attempts." A vehicle is now presumed a lemon if the same nonconformity has been subject to repair three or more times (down from four) by the manufacturer or its authorized dealer within the first 24,000 miles or two years, and the defect continues to exist.
Days Out of Service Threshold
Alternatively, a vehicle qualifies as a lemon if it is out of service by reason of repair for a cumulative total of 24 or more business days (down from 30) during the first 24,000 miles or two years of ownership.
Substantial Impairment Standard
The defect must substantially impair the use, market value, or safety of the vehicle. Minor annoyances, such as a slight rattle or a cosmetic flaw that does not affect the vehicle's functionality or value, typically do not meet this standard.
Safety Defect Provisions
Colorado law includes a stricter standard for safety-based nonconformities. If a defect significantly impacts the safety of the vehicle, it will be presumed a lemon after just two failed repair attempts within the first 24,000 miles or two years.
The Colorado Lemon Law Claims Process
Navigating the lemon law claims process requires strict adherence to statutory procedures and timelines.
Required Steps and Manufacturer Notification
Before a consumer can utilize the presumption that a vehicle is a lemon, they must provide prior written notification by certified mail to the manufacturer. This notice must state that one or more repair attempts have been made and the defect remains. The manufacturer is then given ten business days to cure the alleged defect after receiving the notification.
Documentation Requirements
Consumers should maintain meticulous records of all repair attempts, including repair orders, invoices, and correspondence with the dealer and manufacturer. These documents are crucial for proving the number of repair attempts and the days the vehicle was out of service.
Arbitration Requirements
If a manufacturer participates in an informal dispute settlement procedure that complies with federal regulations (Part 703 of Title 16 of the Code of Federal Regulations), consumers must first resort to this arbitration process before pursuing a refund or replacement under the state lemon law.
Timeline Expectations
The statute of limitations for filing a lemon law claim in Colorado was significantly extended in 2024. Consumers now have 30 months following the date of original delivery to commence an action. Furthermore, this time limit is tolled (paused) during any period the consumer is in arbitration or while the vehicle is unavailable for use due to repairs.
Remedies and Compensation Under Colorado Law
If a vehicle is determined to be a lemon, the manufacturer must provide the consumer with specific remedies.
Vehicle Replacement
The manufacturer has the option to replace the defective motor vehicle with a comparable new motor vehicle.
Repurchase and Refund
Alternatively, the manufacturer may accept the return of the vehicle and refund the full purchase price. This refund includes sales tax, license fees, registration fees, and similar governmental charges.
Mileage Offset Formula: The manufacturer is allowed to deduct a "reasonable allowance for the consumer's use." Colorado law provides a specific formula for this deduction: the total contract price is multiplied by a fraction where the denominator is 100,000 and the numerator is the number of miles the vehicle traveled before the first repair attempt plus any miles traveled during subsequent periods when the vehicle was not out of service for repair.
Attorney's Fees Provisions
To ensure consumers can afford legal representation, the Colorado Lemon Law includes a fee-shifting provision. The court shall award reasonable attorney fees to the prevailing side in any action brought to enforce the provisions of the law.
Affirmative Defenses
Manufacturers may argue affirmative defenses, such as claiming the alleged nonconformity does not substantially impair the vehicle or that the defect is the result of abuse, neglect, or unauthorized modifications by the consumer.
When to Hire a Colorado Lemon Law Attorney
While consumers can pursue claims on their own, hiring an experienced lemon law attorney is often highly beneficial.
Complexity of Claims
Lemon law cases involve specific legal thresholds, strict notification requirements, and complex calculations for mileage offsets. An attorney can ensure all procedural steps are correctly followed.
Manufacturer Resistance Patterns
Manufacturers have teams of lawyers dedicated to minimizing payouts and defending against lemon law claims. An attorney levels the playing field and can effectively counter manufacturer tactics and affirmative defenses.
Fee Structure
Because the Colorado Lemon Law requires the manufacturer to pay the consumer's reasonable attorney fees if the consumer prevails, most lemon law attorneys work on a contingency or fee-shifting basis. This means consumers typically do not pay out-of-pocket for legal representation.
What to Look for in an Attorney
Look for an attorney who specializes in consumer protection and lemon law in Colorado. They should have a proven track record of successfully litigating against major auto manufacturers and a deep understanding of both state and federal warranty laws.
Frequently Asked Questions About Colorado Lemon Law
Does the Colorado Lemon Law cover used cars?
Generally, the Colorado Lemon Law applies to new vehicles. However, if you purchase a used vehicle that is still covered under the manufacturer's original express warranty, you may still have rights. Additionally, the 2024 amendments provide specific disclosure and inspection rights for consumers purchasing used "lemon buyback" vehicles.
How long do I have to file a lemon law claim in Colorado?
Under the updated law, you have 30 months from the date the vehicle was originally delivered to you to file a claim. This period is paused during any time the vehicle is in the shop for repairs or while you are participating in a manufacturer's arbitration program.
What if my vehicle is out of service for a long time but hasn't had three repair attempts?
If your vehicle is out of service for repairs for a cumulative total of 24 or more business days within the first two years or 24,000 miles, it can be presumed a lemon, regardless of the number of individual repair attempts.
Do I have to pay for a lemon law attorney?
In most cases, no. The Colorado Lemon Law includes a provision that requires the manufacturer to pay your reasonable attorney fees if you win your case. Most lemon law attorneys will take your case without requiring upfront payment from you.
Are motorcycles or RVs covered under the Colorado Lemon Law?
No. The Colorado Lemon Law explicitly excludes motor homes and vehicles designed to travel on three or fewer wheels, which means motorcycles and RVs are not covered under this specific state statute. However, they may still be protected under the federal Magnuson-Moss Warranty Act.
