Under Oregon's Lemon Law (ORS 646A.400 to 646A.418), a new motor vehicle is presumed to be a "lemon" if, within the first year after the vehicle was delivered to you or the first 12,000 miles of operation (whichever comes first), the manufacturer or its dealers cannot fix a substantial defect after a reasonable number of attempts. Oregon spells out what "reasonable" means: three or more repair attempts for the same defect, one attempt for a defect likely to cause death or serious bodily injury, or the vehicle being out of service for repairs for a cumulative total of 30 or more business days. If any of those thresholds is met and the defect substantially impairs the vehicle's use, market value, or safety, the manufacturer must either replace the vehicle or refund what you paid. This is a state-specific protection layered on top of the federal Magnuson-Moss Warranty Act, and Oregon's exact triggers differ from those in neighboring states.
Which vehicles and defects qualify in Oregon
Oregon's Lemon Law applies to new motor vehicles bought or leased in Oregon and used primarily for personal, family, or household purposes, plus certain vehicles used in business that fall within the statute. It does not cover the living quarters of motor homes, and it generally does not cover used vehicles purchased after the original warranty period or vehicles bought purely for commercial fleets outside the statute's reach. The protection is tied to the manufacturer's original express written warranty.
Not every flaw qualifies. The defect must be a nonconformity that substantially impairs the use, market value, or safety of the vehicle. Minor annoyances, cosmetic blemishes, or problems caused by your own abuse, neglect, or unauthorized modifications do not count. The defect must also be one that the manufacturer's warranty covers, and you must report it to the manufacturer or an authorized dealer within the coverage window so they have a chance to repair it.
The repair-attempt and days-out-of-service triggers
The heart of Oregon's law is the presumption that a reasonable number of repair attempts has been exhausted. You meet this presumption in one of three ways:
- Three or more attempts to repair the same substantial defect, with the problem still unresolved.
- One attempt to repair a defect that is likely to cause death or serious bodily injury if the vehicle is driven.
- Thirty or more business days out of service, in total, for warranty repair of one or more substantial defects.
These repair events must occur within the lemon law rights period - the first year following original delivery or the first 12,000 miles of operation, whichever arrives first. Keep in mind that Oregon counts business days, not calendar days, for the 30-day out-of-service trigger, and that days can be added together across multiple repair visits.
What you can recover: refund or replacement
Once the vehicle qualifies, Oregon law puts the choice between two remedies in the manufacturer's hands, not necessarily yours, but both are substantial:
- A replacement vehicle that is comparable to the one you bought.
- A refund of the full purchase or lease price you paid, including collateral charges such as sales tax, license and registration fees, and finance charges, minus a reasonable allowance for the use you got out of the vehicle before the defect was first reported.
The "reasonable allowance for use" is an offset based on the mileage you drove before reporting the problem, calculated under a statutory formula. If there is an outstanding loan or lease, the refund is distributed between you and the lender or lessor according to their respective interests. You should not be charged for the manufacturer's repair attempts, and you are entitled to recover incidental costs that flow from the defect.
Exceptions and limits to watch for
A manufacturer can defeat the presumption by showing that the defect does not substantially impair use, market value, or safety, or that the problem was caused by abuse, neglect, or unauthorized alterations rather than a manufacturing fault. The law also has timing limits. The qualifying repair attempts must fall inside the lemon law rights period, and Oregon places an outer limit on how long you have to bring a lawsuit after that period ends. Because the exact limitations period and the use-allowance formula are technical, confirm the current language directly in ORS 646A.400-646A.418 or with a consumer attorney before you assume a claim is time-barred.
