When Is a Car a Lemon in Oregon?

Oregon's § 646A.406 thresholds — 3 attempts, 30 calendar days OOS, or 1 attempt on a serious-injury defect, within the 24-month / 24,000-mile Rights Period.

A car is a “lemon” under Oregon law (§ 646A.400) when:

  1. The vehicle has a nonconformity that substantially impairs its use, market value, or safety.
  2. The defect has not been fixed after a reasonable number of repair attempts.
  3. The thresholds are met within the 24-month / 24,000-mile Rights Period.

The three thresholds

Under § 646A.406:

  • 3 or more repair attempts for the same nonconformity, OR
  • 30 or more cumulative calendar days out of service (60 for motor homes), OR
  • 1 attempt on a defect likely to cause death or serious bodily injury, with a final manufacturer repair attempt, where the defect continues (§ 646A.406(1)(c)).

The 3-attempt threshold is more consumer-favorable than the standard 4-attempt presumption in most states.

What “substantially impair” means

Oregon courts interpret “substantially impair” broadly: use, market value, or safety.

Examples that qualify

  • Transmission shudders / slips repeatedly (Subaru CVT, Nissan CVT).
  • Engine stalls in traffic.
  • Brakes fail / pulse violently.
  • Electrical warning lights / phantom drain.
  • Steering wander or EPS failure (death wobble in pickups).
  • Infotainment locks up.
  • EV charging won’t work.

Examples that typically DON’T qualify

  • Cosmetic issues.
  • Wear items (tires, brake pads after normal use).
  • Consumer-modified parts.
  • Issues outside the 24-month / 24,000-mile Period.
  • Damage from wildfires / hail.

Bottom line

If your OR vehicle has a defect that substantially impairs use, market value, or safety AND has been to the manufacturer’s authorized dealer 3+ times OR 30+ calendar days OOS within the 24-month / 24,000-mile Rights Period, you likely have a Lemon Law case.
