Qualifying Defects: What Counts as a Lemon in Oregon

Oregon’s Lemon Law (§ 646A.402) covers any “nonconformity” — a defect or condition that substantially impairs the use, market value, or safety of the vehicle and is not the result of consumer abuse.

The “substantially impair” test

Under § 646A.402, a “nonconformity” must:

1. Substantially impair the use, market value, or safety of the vehicle.
2. Persist after a reasonable number of repair attempts (3 attempts or 30 calendar days OOS).
3. Be covered under the express manufacturer warranty at the time of the first report.
4. Not be caused by consumer abuse, alteration, or unauthorized modification.

The seven defect categories most often qualifying

1. Transmission — Hard shifts, slipping, fluid leaks, total failure.
2. Engine — Stalling, misfires, excessive oil consumption, knocking, failure.
3. Brakes — Pulsation, dragging, ABS failure, soft pedal, premature wear.
4. Electrical — Battery drain, electrical-system warning lights, module failures.
5. Steering & suspension — Pulling, drift, EPS failure, shock failure, alignment failure.
6. Infotainment — Head unit lockup, Bluetooth/CarPlay failure, backup camera failure.
7. EV-specific — Battery degradation, charging failures, regen brake failures.

What does NOT typically qualify

• Cosmetic — paint, trim, leather (unless safety-related).
• Tires, batteries, wear items — not covered under express warranty.
• Modifications by consumer or unauthorized installers.
• Damage from accidents or environmental (hail, flood, wildfires).
• Issues outside the 24-month / 24,000-mile Rights Period.

Oregon climate / geography factors

• Cold rainy winters — battery, ignition, electrical-connector stress.
• Coastal salt exposure — Oregon Coast (Astoria, Tillamook, Newport, Coos Bay) and Columbia River saltwater proximity.
• Cascade Range mountain driving — Mt. Hood, Santiam Pass, Willamette Pass, Crater Lake area. Sustained brake / transmission stress.
• High desert eastern Oregon — temperature extremes (Bend, Burns, Pendleton).
• Wildfire smoke exposure — HVAC cabin filter stress; some electrical concerns.
• Heavy I-5 / I-84 / I-205 corridor driving — Portland and Salem stop-and-go.
