Colorado Lemon Law
For vehicles sold or leased on or after August 7, 2024 (Senate Bill 24-192), Colorado presumes the manufacturer has had a reasonable number of repair attempts if, within 2 years or 24,000 miles of delivery (whichever comes first), the same defect has been in for repair 3 or more times (2 or more for a safety-related defect) or the vehicle has been out of service for repairs 24 or more business days — but only after the manufacturer receives written notice by certified mail and gets 10 business days to make a final repair. A manufacturer that can't fix the defect must, at its option, replace the vehicle or refund the purchase price, less an allowance for use. In a lawsuit, the court must award reasonable attorney fees to the prevailing side, so a buyer who loses may owe the manufacturer's fees (C.R.S. § 42-10-103(3)). Vehicles sold or leased before August 7, 2024 fall under the earlier version of the law.

If you bought or leased a new vehicle in Colorado that keeps going back to the dealer for the same unresolved defect, you may be protected under Colorado Lemon Law (enacted 1983), codified at Colo. Rev. Stat. § 42-10-101 et seq. This guide explains — in plain English — how the law works, what qualifies a vehicle as a lemon in Colorado, what remedies you can demand from the manufacturer, and how to file a claim. It is not legal advice; when a real dispute emerges you should consult a licensed Colorado consumer attorney.
What the Colorado lemon law covers
Qualifying criteria
The law covers new vehicles and leased vehicles. The defect must appear within the first 24 months of original delivery or before the odometer reaches 24,000 miles, whichever comes first. The manufacturer or its authorized dealer must have had at least 3 opportunities to fix the same defect (or just 2 attempts if the defect poses a serious safety risk). OR the vehicle must have been out of service for at least 24 cumulative business days for warranty repairs during the coverage period.
Your remedies
If your vehicle qualifies, the Colorado lemon law requires the manufacturer to provide a refund or a replacement vehicle. The statute (Colo. Rev. Stat. § 42-10-101 et seq.) decides who chooses between them, what a refund must include — often the purchase price plus taxes and fees — and how much the manufacturer may deduct for your use of the vehicle. A replacement must be comparable to the vehicle it replaces. If you win, Colorado law can also make the manufacturer pay your reasonable attorney's fees, which is why many lemon-law attorneys take these cases without an upfront fee.
How to file a Colorado lemon law claim
Here is how a typical Colorado lemon-law claim unfolds: (1) Keep every repair order the dealer gives you — dates, mileage, the defect description, and the parts replaced. These become your evidence. (2) Send the manufacturer written notice of the defect after the third or fourth repair attempt and request a final repair opportunity. (3) If the manufacturer offers a certified dispute-resolution program, check Colo. Rev. Stat. § 42-10-101 et seq. and your warranty booklet before skipping it — some lemon laws require you to use one before you can sue. (4) Watch the filing deadline: 30 months from original delivery, not counting time in arbitration or while the vehicle is out of service for repair. Check Colo. Rev. Stat. § 42-10-101 et seq. for the exact rule and confirm it with a Colorado lemon-law attorney early.
Federal backup: Magnuson-Moss Warranty Act
Whether or not your claim fits the Colorado lemon law, the federal Magnuson-Moss Warranty Act (15 U.S.C. § 2301 et seq.) provides an independent cause of action whenever a written warranty has been breached. Magnuson-Moss applies in every state, allows you to recover attorney’s fees and costs from the manufacturer when you prevail, and covers used vehicles sold with an express written warranty — filling many of the gaps that narrow state lemon laws leave open.

Check a Colorado VIN for a lemon-law buyback before you buy
Many states require a manufacturer buyback to be branded on the title (California’s “Lemon Law Buyback” brand, for example), but not all do — some only require a written disclosure to the next buyer. A full vehicle history report shows title brands where they were reported; the free VIN check does not.
