RVs and Motor Homes Under the New Mexico Lemon Law
Why motor homes and RVs generally fall outside New Mexico's Motor Vehicle Quality Assurance Act — and how the chassis, UPA, and Magnuson-Moss fill the gap.
Recreational vehicles and motor homes generally fall outside the Motor Vehicle Quality Assurance Act, because they don’t fit the statute’s “passenger motor vehicle” definition (automobile, pickup, motorcycle, or van under 10,000 lbs GVWR for personal/family/household use). Most motor homes exceed the weight limit and aren’t within the enumerated vehicle types.
What’s generally not covered
- Class A, B, and C motor homes — outside the passenger-vehicle definition and typically over 10,000 lbs GVWR.
- Towable RVs — travel trailers and fifth-wheels have no motor and aren’t “motor vehicles.”
The chassis may be different
The chassis and drivetrain of a motor home are manufactured by an automaker (Ford, Ram, Mercedes/Freightliner) and carry their own warranties. Chassis defects — engine, transmission, brakes, steering — may be addressable through:
- The chassis manufacturer’s express warranty.
- Magnuson-Moss on the chassis warranty.
The coach/house portion (appliances, slide-outs, plumbing, build quality) is generally not a lemon-law matter.
What fills the gap
- New Mexico UPA — 4-year SOL; actual or $100 floor; discretionary treble on willful conduct; mandatory fees. Effective for misrepresentation and concealment by RV dealers.
- Magnuson-Moss — federal warranty claims on both chassis and component warranties; § 2310(d)(2) fees.
- Implied warranty of merchantability (N.M. Stat. § 55-2-314).
Common RV issues
- Chassis defects — engine, transmission, brakes (chassis-warranty route).
- Slide-out failures.
- Water intrusion / leaks.
- Electrical / generator faults.
- Appliance failures.
Bottom line
Motor homes and RVs generally fall outside New Mexico’s lemon law, but the chassis may be covered by its automaker’s warranty (and Magnuson-Moss), and the UPA — with its mandatory fees and treble — is the strongest tool for RV-dealer misrepresentation.
