Colorado Lemon Law

Colorado’s lemon law — codified at C.R.S. § 42-10-101 et seq., substantially strengthened by SB24-192 (effective August 7, 2024) — is court-driven (with mandatory manufacturer informal dispute settlement procedure when certified) and uses a 2-year / 24,000-mile eligibility window combined with 3-attempt (2 for safety-related) / 24-business-day OOS thresholds. Combined with the Colorado Consumer Protection Act (CCPA) under C.R.S. § 6-1-101 — which provides mandatory § 6-1-113(2)(b) attorney fees, a $500 statutory penalty, and treble damages on bad-faith violations — Colorado provides solid consumer-favorable remedies.

Colorado is distinctive in four ways:

1. 2-year / 24,000-mile eligibility window — modernized by SB24-192 from the old 1-year window to bring Colorado in line with peer 2-year / 24,000-mile states.
2. 24-business-day OOS threshold — among the shortest out-of-service triggers in the country and uses business-day counting rather than calendar-day counting (most states use 30 calendar days, so 24 business days is roughly 34 calendar days — more consumer-favorable). Joins Massachusetts (15 biz days) and North Carolina (20 biz days) in counting business days.
3. CCPA § 6-1-113(2)(b) mandatory attorney fees + $500 statutory penalty + bad-faith treble damages — strong consumer-favorable framework. The CCPA’s mandatory fees compensate for the Lemon Law’s discretionary fee provision.
4. Mountain altitude / climate vehicle stress — Rocky Mountain descents stress brake systems heavily (Eisenhower Tunnel descent, Wolf Creek Pass, Vail Pass, Independence Pass); high-altitude operation stresses turbochargers and diesel emissions systems (DEF crystallization risk); EV range loss in cold mountain conditions.

Who’s protected

Colorado’s Lemon Law (C.R.S. § 42-10-102) covers:

• New motor vehicles purchased or leased in Colorado for personal, family, or household use.
• Demonstrators sold under new-vehicle warranties.
• Subsequent transferees during the warranty period.

The statute excludes motor homes, motorcycles, off-road vehicles, and vehicles weighing more than 10,000 lbs GVWR.

The 2-year / 24,000-mile window

Colorado’s eligibility window under C.R.S. § 42-10-103 is 2 years from original delivery OR 24,000 miles, whichever first (SB24-192 replaced the old 1-year window effective August 7, 2024). This puts Colorado in line with the mainstream peer states:

• Colorado: 2 years / 24,000 miles
• Georgia, North Carolina, New Jersey, Texas, Washington, Arizona: 2 years / 24,000 miles
• Michigan: 1 year (no mileage cap)
• Massachusetts: 1 year / 15,000 miles (tightest combined)
• Illinois, Pennsylvania: 12 months / 12,000 miles
• Ohio: 12 months / 18,000 miles
• Virginia: 18 months (no mileage cap)

Outside the 2-year / 24,000-mile window, CCPA (3-year SOL) and Magnuson-Moss (4-year limit) remain available.

The “reasonable number of attempts” test

Colorado applies thresholds under C.R.S. § 42-10-103 (as amended by SB24-192):

• Three or more repair attempts for the same general nonconformity, or two or more attempts for a safety-related nonconformity; OR
• 24 or more cumulative business days out of service for repair.

The 24-business-day OOS threshold is distinctive — joins MA (15 biz days) and NC (20 biz days) in using business-day counting. Most states use 30 calendar days; 24 business days roughly equals 34 calendar days — more consumer-favorable.

See our repair-attempt presumption article.

The written notice and 10-business-day cure

SB24-192 added a certified-mail notice with a final repair opportunity. After the consumer serves written notice by certified mail under C.R.S. § 42-10-104, the manufacturer has 10 business days to cure the nonconformity before the consumer can invoke Lemon Law remedies.

The manufacturer’s informal dispute settlement procedure

Under C.R.S. § 42-10-105, if the manufacturer has established a qualifying procedure meeting 16 C.F.R. Part 703 (typically BBB Auto Line), the consumer must use it before filing suit.

What you can recover

A successful Colorado Lemon Law case typically produces:

• Refund — purchase price, sales tax, license fees, plus incidental costs, minus reasonable use deduction.
• Replacement — comparable new vehicle.
• § 42-10-106 attorney fees.
• CCPA $500 statutory penalty + bad-faith treble damages + mandatory § 6-1-113(2)(b) fees.
• Magnuson-Moss attorney fees.
• Reimbursement of incidental damages.

The CCPA two-track approach

Most experienced Colorado lemon-law strategy combines:

• Colorado Lemon Law for refund or replacement plus § 42-10-106 attorney fees.
• CCPA for $500 statutory penalty, treble damages on bad-faith violations, and mandatory § 6-1-113(2)(b) attorney fees.

CCPA in court action provides:

• Actual damages to the consumer.
• $500 statutory penalty per violation.
• Treble damages for bad-faith violations under § 6-1-113(2)(a)(III).
• Mandatory attorney fees under § 6-1-113(2)(b).
• 3-year limitations period under § 6-1-115.

What to do next

1. Document everything. See our evidence guide.
2. Stay within the 2-year / 24,000-mile window.
3. Send certified-mail written notice with the final repair opportunity (manufacturer gets 10 business days to cure).
4. Use the manufacturer’s BBB Auto Line if certified.
5. File court action with parallel CCPA claims for mandatory § 6-1-113(2)(b) fees plus treble damages.
