RVs and Motor Homes Under Utah Lemon Law

Motor homes are excluded from Utah’s New Motor Vehicle Warranties Act under § 13-20-2’s definition of “motor vehicle.” The Lemon Law doesn’t apply — but the chassis component retains independent manufacturer warranty.

UT RV market

Utah has a significant RV market driven by:

• Mighty Five National Parks — Arches, Bryce Canyon, Canyonlands, Capitol Reef, Zion. RV-friendly tourism.
• Lake Powell — recreational RV concentration (Page AZ / southeastern UT).
• Snowbird Spring/Fall transit through UT to/from Arizona / California.
• Wasatch / Cache Valley snowbird retirement market.
• Class A motorhomes + Class B Sprinter/ProMaster vans + Class C Ford E-Series / F-450.

Two coverage tiers

Chassis component — covered under chassis OEM warranty

• Ford F-Series chassis — 6.7L Power Stroke / 7.3L Godzilla; Ford KTP Louisville KY warranty.
• Mercedes Sprinter chassis — Mercedes diesel engines; MBVC Charleston SC warranty.
• Stellantis Ram ProMaster / Ram 3500 chassis — Stellantis warranty.
• Freightliner chassis (Class A) — Daimler Trucks NA Portland OR warranty.

Pursue Magnuson-Moss + UCC + UCSPA against chassis OEM.

House / coach component — RV manufacturer warranty

Common RV manufacturers: Newmar, Tiffin, Winnebago, Fleetwood, Coachmen, Forest River, Thor, Heartland, Jayco, Keystone. Magnuson-Moss applies to RV manufacturer’s express warranty.

No major UT RV manufacturing

UT consumers buy from cross-state RV manufacturers (primarily IN Elkhart cluster + IA Winnebago).

Common UT RV defect patterns

• Slide-out mechanism failures — Schwintek, electric slide-outs.
• Ford 6.7L Power Stroke EGR / turbo / ATS.
• Cummins ISB / ISL engine failures.
• Sprinter DEF-system failures.
• Onan generator failures.
• Coleman / Dometic AC failures.
• Norcold / Dometic refrigerator failures.
• Inverter / converter / electrical.

Utah-specific dynamics

• Mountain elevations stress RV cooling systems and altitude-marginal designs.
• Hot St. George summers stress AC and refrigeration.
• Wasatch Front salt + cold winters — corrosion + cold-soak issues.
• National Park rough roads stress suspension and chassis.

Strategic framework

1. Identify responsible OEM — chassis vs. house.
2. Document repair attempts.
3. Plead Magnuson-Moss against relevant OEM(s).
4. Plead UCC § 70A-2-314 parallel.
5. Plead UCSPA § 13-11-19 for non-disclosure.
6. File in D. Utah federal court.

Bottom line

Motor homes excluded from UT Lemon Law but fully covered by federal Magnuson-Moss + UCC + UCSPA. UT National Park RV market + Wasatch Snowbird transit support meaningful caseload. The UCSPA $2,000 statutory floor applies equally, with the federal Magnuson-Moss claim as the reliable fee anchor.
