The Oregon lemon law requires a manufacturer to replace your vehicle or refund your money if a warranty-covered defect substantially impairs the vehicle’s use, value, or safety and can’t be fixed after a reasonable number of attempts within the first two years or 24,000 miles.1Oregon State Legislature. Oregon Code 646A.402 – Availability of Remedy The statute sits at ORS 646A.400 through 646A.418, and getting the remedy requires written notice to the manufacturer, sometimes arbitration, and a lawsuit filed within one year of the vehicle’s original delivery date.
Which Vehicles and Defects Are Covered
The law covers new passenger vehicles, motorcycles, and the chassis or drivetrain of motor homes purchased or leased for personal, family, or household use.2Oregon State Legislature. Oregon Code 646A.400 – Definitions for ORS 646A.400 to 646A.418 Vehicles bought for resale don’t qualify. If you bought elsewhere and registered the vehicle in Oregon, you’re still protected.
The defect has to substantially impair the vehicle’s use, market value, or safety, and it must be covered by the manufacturer’s express warranty. A transmission that repeatedly leaves you stranded qualifies. A minor trim rattle almost certainly does not. Damage caused by abuse, neglect, or unauthorized modification is excluded, and manufacturers raise those defenses when they can.3OregonLaws. Oregon Revised Statutes 646A.404 – Consumer’s Remedies Keep your maintenance records clean and avoid aftermarket changes to the affected systems while a claim is pending.
One boundary worth naming: used vehicles are not covered by the Oregon statute, even if they still carry manufacturer warranty coverage. That situation is where federal law can pick up, discussed below.
When Oregon Treats Your Vehicle as a Lemon
Oregon presumes the manufacturer has had a reasonable chance to fix the defect, and failed, if either of the following happens within the two-year or 24,000-mile rights period:4Oregon State Legislature. Oregon Code 646A.406 – Presumption of Reasonable Attempt to Conform; Extension of Time for Repairs; Notice to Manufacturer
- The manufacturer, its agent, or an authorized dealer has attempted to repair the same defect three or more times and it persists.
- The vehicle has been out of service for repairs for a cumulative 30 or more calendar days. For motor homes, the threshold is 60 calendar days.
The details matter. The statute says three attempts, not four. The 30-day count uses calendar days, so weekends and holidays the vehicle spends at the dealer count. And every repair visit needs to fall inside the rights period, though a defect first reported before the window closes can carry through later visits.
The presumption shifts the burden to the manufacturer to prove your vehicle isn’t a lemon. Without it, that burden is yours. And the presumption only takes hold if the manufacturer has already received written notice and had a chance to fix the problem, so skipping that step can wipe out the presumption regardless of how many dealer visits you’ve logged.
Sending Written Notice to the Manufacturer
Before you can demand a refund or replacement, you have to send the manufacturer direct written notice describing the defect and giving an opportunity to repair it.4Oregon State Legislature. Oregon Code 646A.406 – Presumption of Reasonable Attempt to Conform; Extension of Time for Repairs; Notice to Manufacturer The notice goes to the manufacturer’s corporate address, not your local dealer. Look in the owner’s manual or warranty booklet for the correct mailing address.
Keep the letter factual. Describe the defect, list each repair date with the mileage at that visit, attach copies of the repair orders, and state that you are requesting relief under Oregon’s lemon law. Send it certified mail with return receipt so you have a stamped date of delivery. Filing a request for the manufacturer’s informal dispute settlement program also counts as written notice under the statute.
Refund or Replacement, and What the Refund Actually Includes
If repair attempts fail, the manufacturer must either replace the vehicle with a new one or take it back and refund your money.3OregonLaws. Oregon Revised Statutes 646A.404 – Consumer’s Remedies The choice usually rests with the manufacturer, though an arbitration decision or court order can dictate the outcome.
A refund includes the full purchase or lease price plus collateral charges, which cover items like sales tax, registration fees, and finance charges paid in the transaction. If a lien is on the vehicle, the refund is split between you and the lienholder according to each party’s interest.
The manufacturer subtracts a usage allowance for the driving you got out of the vehicle before returning it. For a standard passenger car, the formula is: mileage at return, minus 10 miles per day the vehicle was in the shop for repairs, multiplied by the total you paid (price plus collateral charges), divided by 120,000.5Oregon State Legislature. Oregon Laws 2009 Chapter 448 Motorcycles use a divisor of 25,000, and motor homes use 90,000, which makes the per-mile deduction steeper for those vehicles. The earlier you report the defect and start the process, the smaller this deduction becomes.
Arbitration Before Court
If the manufacturer runs an informal dispute settlement program that meets federal standards under 16 CFR Part 703, you have to go through it before filing a lawsuit for refund or replacement.6Oregon State Legislature. Oregon Revised Statutes Chapter 646A – Trade Regulation – Section: 646A.408 Several major manufacturers use programs administered through the Better Business Bureau to handle Oregon lemon law disputes.7Oregon Department of Justice. Lemon Law – Consumer Protection
Federal rules require these programs to resolve disputes within 40 days, charge you nothing, and use decision-makers independent of the manufacturer.8eCFR. 16 CFR Part 703 – Informal Dispute Settlement Procedures The panel’s decision does not bind you. If you lose or the manufacturer refuses to comply, you can still sue. If the manufacturer has no qualifying program, you can skip arbitration and go straight to court.
The One-Year Deadline to File Suit
Oregon requires you to file a lemon law lawsuit within one year of the vehicle’s original delivery date.9Oregon State Legislature. Oregon Revised Statutes Chapter 646A – Trade Regulation – Section: 646A.412 This is shorter than the two-year window for reporting defects, and it catches a lot of people. If your third repair attempt lands at month nine, you have roughly three months to send written notice, complete arbitration, and file suit. Miss it and the state claim is gone.
A court can award reasonable attorney fees to the prevailing party, which is what makes these cases economically viable for consumers to bring.
When Federal Magnuson-Moss Helps Instead
The federal Magnuson-Moss Warranty Act applies to any product sold with a written warranty, which means it can cover a used vehicle still under manufacturer warranty, where the Oregon statute cannot. If you win a warranty claim under the federal act, the court can order the manufacturer to pay your attorney fees and litigation costs.10Office of the Law Revision Counsel. United States Code Title 15 Section 2310 – Remedies in Consumer Disputes That fee-shifting rule is why most lemon law attorneys take these cases on contingency.
A manufacturer can require you to complete a qualifying informal dispute settlement program before suing under Magnuson-Moss too, as long as the program meets 16 CFR Part 703.8eCFR. 16 CFR Part 703 – Informal Dispute Settlement Procedures
Documentation That Makes or Breaks the Claim
Records are what turn a lemon law claim from a complaint into a case. Start collecting from the first visit.
- A written repair order from every dealer visit showing the date, mileage, the complaint as you described it, and the work performed. If the dealer couldn’t replicate the problem, that should be on the order. Ask for a copy before you leave.
- Emails, texts, and chat transcripts with the dealer and manufacturer, plus a call log noting date, person, and what was said.
- The purchase or lease contract and financing paperwork, which set the numbers a refund is built on.
- The warranty booklet, which contains the express warranty terms and the manufacturer’s notice address.
- The vehicle identification number, which goes on every letter and filing.
Keep originals safe and send copies with your notice, arbitration filing, or lawsuit. A dated stack of repair orders, a certified mail receipt for the written notice, and a clean timeline of the defect are what get a manufacturer to treat the claim seriously.
