Colorado Lemon Law (2026): How to Qualify & Get a Refund

Colorado's lemon law, the Motor Vehicle Repair Act under C.R.S. § 42-10-101, covers new private passenger vehicles and triggers the lemon presumption when the same defect persists after three repair attempts, two attempts for a safety defect, or 24 business days out of service within two years or 24,000 miles.

Understanding Colorado's Updated Lemon Law

Colorado's lemon law, officially known as the Motor Vehicle Repair Act, is codified in Colorado Revised Statutes § 42-10-101 through § 42-10-109. The law provides important consumer protections for buyers and lessees of new motor vehicles that fail to conform to the manufacturer's express warranty.

On August 7, 2024, Senate Bill 24-192 took effect and brought the most significant changes to Colorado's lemon law in decades. The update lowered the threshold for a vehicle to qualify as a lemon, expanded which vehicles are covered, extended filing deadlines, and introduced new protections for buyers of lemon buyback vehicles.

The Colorado Attorney General's office issued a public advisory encouraging consumers to understand their new rights under the updated law. These changes apply to vehicles originally delivered to consumers on or after the effective date.

What Vehicles Are Covered

Colorado's lemon law covers specific types of vehicles purchased or leased in the state. The 2024 update expanded coverage to include small business vehicles.

Covered Vehicle Types

• New private passenger vehicles: Cars, sedans, coupes, and similar automobiles
• Trucks: Pickup trucks used primarily for personal purposes
• Vans: Passenger vans and minivans
• SUVs: Sport utility vehicles
• Leased vehicles: New vehicles obtained through lease agreements
• Demonstrator vehicles: Demo vehicles sold as new with warranty
• Small business vehicles: Vehicles used for both personal and business purposes (added by SB24-192)

Vehicles Not Covered

• Used vehicles (separate protections exist for lemon buyback vehicles)
• Motorcycles and vehicles with three or fewer wheels
• Motor homes as defined in C.R.S. § 42-1-102
• Vehicles modified for commercial use
• Vehicles designed to carry more than ten people (Colorado's lemon law only covers private passenger vehicles, including pickups and vans, designed to carry ten or fewer people)

Colorado's Lemon Law Presumption (Updated 2024)

Colorado law creates a rebuttable presumption that a reasonable number of repair attempts have been made when certain conditions occur within the coverage period. SB24-192 lowered these thresholds to make it easier for consumers to qualify.

The Lemon Law Presumption Applies When

Before this presumption can be invoked, the consumer must send the manufacturer written notice by certified mail stating that repair attempts have been made and the defect remains. SB24-192 added a new precondition: the manufacturer must then be given 10 business days after receiving that notice to attempt to cure the defect before the presumption applies. That cure attempt counts as one of the repair attempts toward the total (C.R.S. § 42-10-103(2)(c)).

What Changed in 2024

The table below compares the old and new lemon law presumption requirements.

Important: Colorado uses business days for the out-of-service calculation. Business days typically exclude Saturdays, Sundays, and state holidays.

What Qualifies as a "Nonconformity"?

A nonconformity is any defect or condition that substantially impairs the use, market value, or safety of the motor vehicle. Examples include:

• Engine failures or persistent performance problems
• Transmission defects affecting drivability
• Brake system malfunctions
• Steering problems creating safety hazards
• Electrical failures affecting critical systems
• Heating and defrost system failures (particularly important in Colorado's climate)
• Four-wheel drive or all-wheel drive system defects
• Suspension problems affecting handling

Safety-Based Nonconformities

SB24-192 introduced the concept of a "safety-based nonconformity," defined as a defect that results in a condition likely to cause death or serious bodily injury if the vehicle is driven, or that creates a risk of fire or explosion. These defects receive a lower threshold of only two repair attempts before the lemon presumption applies.

Consumer Remedies: Refund or Replacement

When a vehicle qualifies as a lemon under Colorado law, the manufacturer must provide either a comparable replacement vehicle or a full refund. Under C.R.S. § 42-10-103, the manufacturer chooses which remedy to provide. The statute uses the phrase "at the manufacturer's option," so the manufacturer may prefer whichever remedy costs less in a given situation. Consumers should document their preference in writing when notifying the manufacturer.

Option 1: Replacement Vehicle

If the manufacturer chooses replacement, it must provide:

• A comparable new motor vehicle
• All applicable express warranties
• Reimbursement for incidental costs including registration and taxes

Option 2: Refund (Buyback)

If the manufacturer chooses a refund, it must provide:

• Full purchase price: Including sales tax and fees
• License and registration fees: All DMV costs
• Collateral charges: Dealer fees and similar costs
• Finance charges: Interest and loan fees paid
• Incidental damages: Towing, rental cars, and related costs

Updated Usage Deduction Formula

The manufacturer may deduct a reasonable allowance for the consumer's use of the vehicle. SB24-192 clarified the formula to ensure fair and predictable calculations.

The usage deduction is calculated as:

Usage Deduction = (Total Contract Price) x (Eligible Miles / 100,000)

"Eligible Miles" includes only:

• Miles traveled before the consumer first presented the vehicle for repair of the nonconformity
• Miles traveled during any subsequent period when the vehicle was not out of service by reason of repair

This formula protects consumers by excluding miles the vehicle spent sitting in a repair shop from the usage calculation. For example, on a $40,000 vehicle where the consumer drove 5,000 eligible miles, the usage deduction would be $2,000.

The Magnuson-Moss Warranty Act: Federal Backstop

Colorado consumers may also have rights under the federal Magnuson-Moss Warranty Act, 15 U.S.C. § 2301 et seq., regardless of whether the state lemon law applies. Magnuson-Moss allows consumers to sue in federal court for breach of a written or implied warranty on any consumer product, including vehicles. If you prevail, the manufacturer pays your attorney's fees under 15 U.S.C. § 2310(d)(2). The federal law provides an independent remedy that can be pursued alongside a Colorado state lemon law claim, and is particularly useful if your vehicle does not quite meet the state thresholds but the manufacturer has clearly breached the written warranty.

How to File a Lemon Law Claim in Colorado

Filing a successful lemon law claim in Colorado requires proper documentation and following specific procedures.

Step 1: Document Everything

• Keep all repair orders and invoices
• Record dates your vehicle entered and left the repair shop
• Document the specific problems and symptoms
• Save all correspondence with the dealer and manufacturer
• Photograph or video defects when possible
• Keep receipts for rental cars and towing

Step 2: Allow Reasonable Repair Attempts

Give the manufacturer or its authorized dealer adequate opportunity to repair the vehicle. You need at least three attempts for the same problem, two attempts for a safety-related defect, or 24 business days out of service to invoke the presumption.

Step 3: Provide Written Notice to Manufacturer

Before pursuing remedies, send written notice to the manufacturer by certified mail that includes:

• Your name and contact information
• Vehicle information (year, make, model, VIN)
• Description of the nonconformity
• Repair history summary with dates
• Your requested remedy (replacement or refund)

Once the manufacturer receives this notice, it has 10 business days to attempt to cure the defect before the repair-attempt presumption can be counted against it (C.R.S. § 42-10-103(2)(c), added by SB24-192). That cure attempt itself counts as one of the required repair attempts.

Step 4: Participate in Arbitration if Required

Under C.R.S. § 42-10-106, if the manufacturer has established an informal dispute settlement procedure that complies with federal regulations (16 C.F.R. Part 703), consumers must use that procedure before pursuing refund or replacement remedies. The 30-month statute of limitations is tolled (paused) during the arbitration process.

Not all manufacturers maintain qualifying arbitration programs. If no qualifying program exists, you can proceed directly to court.

Step 5: File a Lawsuit if Necessary

If arbitration does not resolve the dispute or no arbitration program exists, you may file a lawsuit in Colorado state court. The court shall award reasonable attorney fees to the prevailing party in any lemon law action.

Filing Deadline

You must file your lemon law claim within 30 months of the original delivery of the vehicle to you. This deadline is tolled during any period when:

• You have submitted to manufacturer arbitration under § 42-10-106
• The vehicle is out of service by reason of repair

Manufacturer Defenses

Manufacturers may raise several defenses to avoid lemon law liability in Colorado.

Common Manufacturer Defenses

Lemon Buyback Vehicle Protections

SB24-192 added new C.R.S. § 42-10-108 and § 42-10-109, creating protections for buyers of vehicles that were previously repurchased under the lemon law.

Disclosure Requirements

Dealers selling lemon buyback vehicles must:

• Affix a permanent decal reading "Lemon Law Buyback" on the driver's door B pillar (the body post to which the driver's door latches)
• Ensure the vehicle's title indicates its lemon law buyback status
• Provide conspicuous written disclosure of the vehicle's history before sale
• Never remove the lemon law buyback decal

Third-Party Inspection and Free-Look Period

Dealers selling lemon buyback vehicles must offer one of the following:

• Third-party inspection: Allow the buyer's agent to inspect the vehicle before purchase. The agent must be qualified to use any inspection equipment and must not interfere with normal dealer operations.
• 7-day free-look period: The purchaser may return the vehicle within seven days and receive a full refund of all money paid, less shipping costs.

These protections help consumers make informed decisions about purchasing vehicles with lemon law histories.

Used Vehicle Protections

Colorado's lemon law does not cover used vehicles (other than the lemon buyback provisions above). However, used car buyers have other potential protections.

Available Protections for Used Vehicles

• Remaining manufacturer warranty: Used vehicles still under warranty may have warranty claims
• Dealer warranties: Some dealers offer limited warranties on used vehicles
• Implied warranty of merchantability: Unless properly disclaimed, vehicles must be fit for ordinary use
• Federal Magnuson-Moss Warranty Act: Provides remedies for warranty breaches on products with written warranties
• Colorado Consumer Protection Act: Protects against dealer fraud, misrepresentation, and unfair business practices

Title Branding

Colorado requires that vehicles repurchased under the lemon law have their titles branded to notify future buyers of the vehicle's history. Under the 2024 update, this branding requirement is reinforced by the physical decal requirement.

Statute of Limitations and Key Deadlines

Colorado's lemon law has specific timeframes that consumers must follow.

Filing a Complaint with the Colorado Attorney General

Consumers who believe a manufacturer or dealer has violated the lemon law can file a complaint with the Colorado Attorney General's Consumer Protection Division. While the AG's office does not typically represent individual consumers in lemon law cases, complaints help the office identify patterns of violations and take enforcement action.

You can file a complaint online at coag.gov/file-complaint or by calling the consumer protection hotline.
