Colorado auto repair regulations.

Under AQCC Regulation 25 Section I.P, beginning May 1, 2026 automotive coatings above the Table 4 VOC limits (e.g., primer and clearcoat 250 g/L, color coat 420 g/L) may not be manufactured, sold or distributed in Colorado, and covered automotive coating facilities in the regulated ozone areas must use Table 4-compliant coatings or 90%-efficient controls.

Under Colorado SB 24-123, retailers of new motor-vehicle and trailer tires began collecting both the waste-tire enterprise fee and the waste-tire administration fee at the point of sale on July 1, 2025, with required receipt language tied to the new fee structure.

Colorado SB 23-078 changed the state's dealer warranty reimbursement law. Manufacturers must compensate dealers at the statutory retail labor rate and parts markup for covered warranty repairs, and a manufacturer contesting a dealer's submitted rates must base the challenge on material inaccuracy rather than simply pointing to different rates at similarly situated dealers.
