Commercial Vehicles Under Mississippi Lemon Law

Mississippi’s Motor Vehicle Warranty Enforcement Act under § 63-17-153 excludes:

• Vehicles over 10,000 lbs GVWR — most Class 3+ commercial trucks.
• Vehicles used primarily for commercial purposes — fleet vehicles, even under 10,000 lbs GVWR.

Federal Magnuson-Moss applies and provides the primary statutory pathway.

What’s excluded from MS Lemon Law

Heavy-duty trucks (over 10,000 lbs GVWR)

• Freightliner Cascadia, Western Star (Daimler Trucks NA Portland OR).
• Volvo VNL (Volvo Trucks NC).
• PACCAR Kenworth, Peterbilt (PACCAR plants MS, TX, WA).
• Mack Trucks (Allentown PA).
• Ford F-650, F-750 Medium-Duty.
• Ram 3500/4500/5500 (Cummins-equipped HD trucks above 10K GVWR).

Primarily-commercial-use vehicles

• Fleet pickup trucks (F-150, Ram 1500, Silverado 1500 fleet-deployed).
• Fleet vans (Ford Transit Connect, Ram ProMaster City, Mercedes Metris).
• Delivery vans (Ford Transit, Mercedes Sprinter, Ram ProMaster) when commercial-use predominant.

The “primarily commercial” test is fact-intensive.

What’s covered through Magnuson-Moss + UCC

Federal Magnuson-Moss has no 10,000 GVWR threshold or commercial-use exclusion:

• Federal Magnuson-Moss § 2310(d)(1)(B) claim.
• UCC § 75-2-314 implied merchantability against manufacturer and dealer.
• Mandatory § 2310(d)(2) attorney fees.
• 4-year UCC SOL backstop under § 75-2-725.

The AIC threshold ($50,000 for federal Magnuson-Moss jurisdiction) easily satisfied for commercial vehicles.

MS commercial market

• Gulf Coast shipping and offshore services — Pascagoula, Gulfport, Biloxi port operations; offshore energy services.
• Agricultural fleet — Mississippi Delta cotton, soybean, rice operations.
• Forestry industry — central and southern MS pine timber.
• Casino fleet — Tunica, Vicksburg, Biloxi gaming operations.
• Federal facilities — Stennis Space Center, Naval Construction Battalion Center.

Common MS commercial-fleet defect patterns

• Freightliner Cascadia — Detroit DD13/DD15 engine, ATS aftertreatment failures, electrical issues.
• PACCAR Kenworth / Peterbilt — PACCAR MX engine, ATS failures.
• Ford F-Super-Duty — death-wobble paradigm, 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 (commercial fleet) — DEF-system failures, OM651/OM642 diesel.
• Ford Transit — 3.5L EcoBoost, 10R80 transmission.
• Ram ProMaster — Stellantis 3.6L Pentastar, ZF 6-speed.

MS commercial-vehicle venues

• S.D. Miss. — Jackson (state-capital + Nissan Canton), Hattiesburg (Gulf Coast), Western Division.
• N.D. Miss. — Oxford (north-central, Toyota Blue Springs), Aberdeen (northeast), Greenville (Delta).

Cross-state defendant manufacturers typically appear by counsel from their HQ states.

Strategic framework

1. Determine GVWR and commercial-use percentage — does AR Lemon Law apply?
2. Document repair attempts at manufacturer-authorized facilities.
3. Plead Magnuson-Moss as primary federal cause of action.
4. Plead UCC § 75-2-314 as parallel theory.
5. Plead narrowed MCPA for non-disclosure.
6. File in S.D. Miss. or N.D. Miss. federal court.

Bottom line

MS commercial-vehicle cases bypass the Lemon Law but recover through federal Magnuson-Moss + UCC + mandatory § 2310(d)(2) fees. MS Gulf Coast / agricultural / forestry / casino commercial-fleet market drives meaningful caseload. Federal venue is the standard.
