Commercial-use vehicles face limited coverage under Oregon’s Lemon Law (§ 646A.400). The statute excludes vehicles above 10,000 lbs GVWR and vehicles purchased for commercial-only use. Daimler Trucks North America HQ in Portland is the home-state defendant for heavy-duty Freightliner / Western Star cases.

§ 646A.400 exclusions

Section 646A.400 excludes:

  • Vehicles above 10,000 lbs GVWR.
  • Vehicles purchased for commercial use (not personal/family/household).
  • Motor homes above 10,000 lbs (except chassis).

Common exclusion lines

  • Ford F-450, F-550, F-650/750 — typically above 10,000 lbs GVWR.

  • Freightliner — heavy-duty Class 8 trucks.
  • Western Star — heavy-duty trucks.
  • Detroit Diesel — diesel engines.

For Oregon plaintiffs with Freightliner / Western Star issues (all above 10K GVWR, so § 646A.400 excluded):

  • Magnuson-Moss applies regardless of GVWR.
  • UCC + UTPA apply.
  • D. Or. (Portland) federal venue, with discovery access to DTNA Portland HQ.
  • Home-state defendant venue advantage in Magnuson-Moss / UTPA cases.

Alternative remedies for excluded vehicles

For commercial-use or >10K GVWR vehicles:

  • Magnuson-Moss Warranty Act — applies regardless of GVWR.
  • UCC § 72.3130 / § 72.3140 — express + implied warranties.
  • Oregon UTPA — applies to commercial transactions (with some limitations).

Oregon commercial-vehicle market

  • I-5 corridor — major freight movement.
  • Port of Portland — Class I rail interchange (BNSF, UP).
  • Daimler Trucks Portland HQ — substantial fleet manufacturing.
  • Agriculture + forestry in eastern Oregon.

Bottom line

Commercial vehicles above 10K GVWR are typically excluded from § 646A.400. Magnuson-Moss + UCC + UTPA remain available. Daimler Trucks Portland home-state factor benefits Freightliner / Western Star plaintiffs in D. Or. (Portland) federal court.
