Oregon Lemon Law: Tests, Refunds & Free Car Check

The short answer

Oregon’s Lemon Law (ORS 646A.400 to 646A.418) covers defects reported within 2 years or 24,000 miles. After direct written notice to the manufacturer, it presumes enough attempts after 3 repairs, 1 repair plus a final attempt for a serious safety defect, or 30 days out of service (60 for motor homes). Refunds deduct miles × (price + collateral charges) ÷ 120,000. Sue within 1 year after the period ends.

Oregon gives owners some unusual tools: a court can award up to three times damages, up to $50,000 extra, when a manufacturer does not act in good faith, and a manufacturer program’s decision binds the manufacturer but not you. This guide explains the tests, the notice, the refund formula for cars, motorcycles and motor homes, and the deadline, from ORS chapter 646A.

Three repairs, one safety repair or 30 days in Oregon

Oregon presumes a reasonable number of attempts when, within 2 years or 24,000 miles of delivery (whichever ends first), after direct written notice to the manufacturer:

1×

Serious Safety Defect Test

A defect likely to cause death or serious bodily injury was repaired at least once, then a final repair attempt, and continues.

ORS 646A.406(1)(c)
3×

Three Repairs Test

The same defect was repaired 3 or more times and the manufacturer had an opportunity to cure, but it continues.

ORS 646A.406(1)(a)
30

30 Days Out of Service Test

Out of service for repair a cumulative total of 30 or more calendar days (60 for a motor home).

ORS 646A.406(1)(b)

The defect must substantially impair the vehicle’s use, market value or safety. A repair needed after the 2-year or 24,000-mile period still counts toward the tests (ORS 646A.406(2)).

Notice to the manufacturer in Oregon

The manufacturer must receive direct written notification from you or on your behalf and have an opportunity to correct the defect. A request for the manufacturer’s informal dispute procedure counts as notification.

In Oregon the remedy and the presumptions need direct written notice to the manufacturer and a chance to cure.

Dispute program first. If the manufacturer has an informal dispute procedure complying with FTC Rule 703 and tells you about it, you must use it first. Its arbitration decision binds the manufacturer but not you (ORS 646A.408).

Asking for the manufacturer’s informal dispute procedure counts as notification (ORS 646A.402(3)).

Oregon’s 1-year deadline after the window

Start an action within 1 year after the 2-year or 24,000-mile period ends, whichever ends earlier (ORS 646A.416).

Refund, replacement and the Oregon deduction for use

Oregon Lemon Law remedies
RemedyWhat it includes
ReplacementA new motor vehicle.
RefundThe full purchase or lease price and collateral charges paid (taxes, title and registration fees, finance charges, prepayment penalties, options and aftermarket items bought within 20 days), less a reasonable allowance for use.

How the Oregon deduction for use is calculated

mileage when the manufacturer replaces or repurchases × (cash or lease price + collateral charges) ÷ 120,000 (motorcycles ÷ 25,000; motor homes ÷ 90,000) (ORS 646A.404(3)).

Worked example: $36,000 vehicle, first repair at 6,000 miles, 15,000 miles today
StepMathAmount
Purchase price—$36,000.00
Deduction for use15,000 miles × $36,000 ÷ 120,000−$4,500.00
Refund before taxes, fees and other chargesThose are added under the rules above$31,500.00

Oregon’s refund formula for cars, motorcycles and motor homes

Oregon multiplies the mileage when the manufacturer replaces or repurchases the vehicle by the cash or lease price plus collateral charges, then divides by a figure that depends on the vehicle (ORS 646A.404(3)).

Divisors and an example at 15,000 miles on $40,000 (price + collateral charges)
VehicleDivisorDeduction
Car or truck120,000$5,000.00
Motor home90,000$6,666.67
Motorcycle25,000$24,000.00

Collateral charges include sales, property or use tax, license, registration and title fees, finance charges, prepayment penalties, undercoating and dealer options, and aftermarket items bought within 20 days of delivery.

Treble damages and buyback disclosure

  • If a court grants a refund or replacement and finds the manufacturer did not act in good faith, you can also receive up to three times damages, capped at $50,000 above the refund or replacement (ORS 646A.412).
  • A manufacturer that replaces or repurchases a vehicle must have it titled in its own name with the notation “Lemon Law Buyback”, and a later seller must give the buyer a signed notice saying so (ORS 646A.405).

If you choose to pursue another remedy in court, the lemon law recovery is limited unless you prove fault and greater damages (ORS 646A.418).
