Lemon-law presumption checklist · Oklahoma
Enter your repairs to check the presumption

This checklist is educational, not a legal verdict. Every state writes these numbers as a rebuttable presumption: hitting them shifts the burden to the manufacturer, and the manufacturer can still rebut it. Keep every repair order, send any required written notice, and consult a lawyer about your specific facts. This is legal information, not legal advice.

How the presumption works in Oklahoma

The prongs that shift the burden to the manufacturer.

Same-defect repair attempts
4 attempts on the same defect (presumption trigger)
Days out of service
30 business days
What you must show
The defect must substantially impair the use and value of the vehicle and be covered by the express warranty. The consumer must report each nonconformity within the express warranty term or the first year after delivery, whichever ends first, and the defect must continue to exist after those attempts.

Oklahoma sets the out-of-service trigger at a cumulative 30 business days — the same threshold most states use — and the statute counts business days, not calendar days. The one-year and 30-day periods are extended by any time repair service is unavailable because of war, strike, fire, flood, or other natural disaster.

These numbers are a presumption, not a hard gate

Every state, Oklahoma included, writes these thresholds as a rebuttable presumption. Reaching them shifts the burden onto the manufacturer to prove your vehicle is not a lemon; it does not mean you automatically win. You may also qualify with fewer attempts if a "reasonable number" of repairs is shown some other way, and the manufacturer can rebut the presumption. This is legal information, not legal advice.

Used cars & leased vehicles

Which of the three coverage categories Oklahoma falls in.

Category CNew vehicles only
Used cars
Oklahoma’s lemon law under 15 O.S. §901 applies to a new motor vehicle reported nonconforming during the express warranty or the first year after delivery. The state has no standalone used-car lemon law.
Leased vehicles
Covered. Oklahoma treats a lessee as a protected consumer.

What Oklahoma car buyers get wrong

Oklahoma’s lemon law lives in Title 15, Section 901 of the state statutes. It presumes a "reasonable number of attempts" once the same nonconformity has been repaired 4 or more times, or the vehicle has been out of service for a cumulative 30 or more business days, all measured within the earlier of the express warranty term or 1 year after delivery. Both figures are presumption triggers: hitting them shifts the burden to the manufacturer rather than deciding the case outright. The statute counts business days, not calendar days, so weekends and holidays a shop is closed do not count against the 30. Oklahoma covers new vehicles only and has no separate used-car lemon law, though the express warranty can still reach a used car sold while that factory warranty is active. The statute also stops the clock during forced repair delays, so time lost to a strike, fire, flood, or other disaster extends both the one-year and the 30-day periods.

Common questions

How many repair attempts make a car a lemon in Oklahoma?

Oklahoma presumes a lemon after 4 repair attempts on the same nonconformity, or after the vehicle is out of service for a cumulative 30 or more business days, within the earlier of the warranty term or 1 year from delivery. These are presumption triggers that shift the burden to the manufacturer.

How many days out of service trigger Oklahoma’s lemon-law presumption?

Thirty business days. The statute (15 O.S. §901(D)) sets the cumulative out-of-service threshold at "thirty (30) business days," counting business days rather than calendar days, which matches the figure most other states use.

Does the Oklahoma lemon law cover used cars?

No. Oklahoma has no standalone used-car lemon law. Section 901 applies to a new motor vehicle whose nonconformity is reported during the express warranty or the first year after delivery.

How long do I have to report a defect under Oklahoma’s lemon law?

You must report each nonconformity within the earlier of the express warranty term or 1 year following original delivery. That deadline can be extended if repair service was unavailable because of a war, strike, fire, flood, or other natural disaster.
