Commercial Vehicles Under Utah Lemon Law

Utah’s New Motor Vehicle Warranties Act under § 13-20-2 excludes vehicles primarily used for commercial purposes. Federal Magnuson-Moss applies and provides the primary statutory pathway.

What’s excluded from UT Lemon Law

• Heavy-duty trucks (typically over 10,000 lbs GVWR Class 3+) — Freightliner, Volvo, PACCAR, Mack.
• Primarily-commercial-use vehicles — fleet pickup trucks, fleet vans, delivery vans.

The “primarily commercial” test is fact-intensive.

UT commercial market

• Mining — Bingham Canyon copper, Kennecott, Rio Tinto. Heavy commercial vehicle fleet.
• Construction — Wasatch Front rapid growth + I-15 corridor expansion. Concrete trucks, dump trucks, equipment haulers.
• Distribution / logistics:
  • Sysco Salt Lake City — food distribution; large Class 8 fleet.
  • U.S. Foods.
  • Costco regional distribution.
  • Amazon facilities SLC area.
• Petroleum — Wasatch refining (Salt Lake) heavy commercial transport.
• Mountain-resort fleet — Park City / Snowbird / Brighton / Alta shuttle and maintenance fleet.

What’s covered through Magnuson-Moss + UCC + UCSPA

Federal Magnuson-Moss has no commercial-use exclusion for vehicles with express warranties:

• 15 U.S.C. § 2310(d)(1)(B) federal claim.
• UCC § 70A-2-314 implied merchantability.
• UCSPA § 13-11-19 — $2,000 statutory floor + discretionary prevailing-party fees.
• Mandatory-character § 2310(d)(2) federal fees (the reliable anchor).
• 4-year UCC SOL under § 70A-2-725.

The AIC threshold easily satisfied for commercial vehicles.

Common UT commercial-fleet defect patterns

• Freightliner Cascadia — Detroit DD13/DD15 engine, ATS aftertreatment failures.
• PACCAR Kenworth / Peterbilt — PACCAR MX engine, ATS failures.
• Ford F-Super-Duty — death-wobble, 6.7L Power Stroke EGR/turbo.
• Ram 2500/3500 + Cummins 6.7L — fuel-system, ATS aftertreatment.
• GM Silverado HD / Sierra HD — Duramax / Allison; ATS failures.
• Mercedes Sprinter — DEF-system failures, OM651/OM642 diesel.
• Ford Transit — 3.5L EcoBoost, 10R80 transmission.
• Ram ProMaster — Stellantis 3.6L Pentastar, ZF 6-speed.

Utah-specific dynamics

• Altitude stresses turbo / diesel engines; turbo-related failures common.
• Mountain-resort fleet — heavy duty-cycle from sustained shuttling.
• Bingham Canyon mining — Class 8 fleet faces extreme duty-cycle stress.
• Cold winter cold-soak + brine exposure (Wasatch Front).

Federal venue

D. Utah:

• Salt Lake City Division — Wasatch Front commercial-fleet operators.
• Logan Division — northern UT.
• St. George Division — southern UT (less commercial fleet).

Strategic framework

1. Determine GVWR + commercial-use percentage.
2. Document repair attempts at manufacturer-authorized facilities.
3. Plead Magnuson-Moss primary federal cause of action.
4. Plead UCC § 70A-2-314 parallel.
5. Plead UCSPA § 13-11-19 with the $2,000 statutory floor for non-disclosure.
6. File in D. Utah federal court.

Bottom line

UT commercial-vehicle cases bypass the Lemon Law but recover through federal Magnuson-Moss + UCC + UCSPA. UT mining + construction + distribution + resort-fleet markets drive substantial commercial-vehicle caseload. The UCSPA $2,000 statutory floor applies equally, with the federal Magnuson-Moss claim carrying the reliable fee economics.
