Ohio lemon law: how to file (2026)

The complete, plain-English walkthrough — built from the Ohio Attorney General's Lemon Law publications and Ohio Revised Code §§1345.71–.78, not law-firm marketing. Last reviewed September 30, 2026.

What vehicles are covered

Ohio's lemon law (Ohio Rev. Code §§1345.71–.78) covers new passenger cars and noncommercial motor vehicles — per the Ohio AG, "passenger cars, motorcycles and other noncommercial motor vehicles, which are designed to carry no more than a one-ton load and are used exclusively for personal use." Leases of 30 days or more count. The AG says the law generally doesn't cover used cars, unless the problems occur within the vehicle's first year or first 18,000 miles.

Not covered: mobile homes, recreational vehicles, manufactured homes, and commercial vehicles. Motor homes are covered only for their driving (non-living-facility) parts — permanently installed cooking, sleeping, and cold-storage facilities are excluded.

The four tests (including a safety shortcut)

A "reasonable number of attempts" is presumed if, during the first year after delivery or the first 18,000 miles (whichever is earlier), any one of these happened:

1. Three-times test

The same nonconformity persists after 3 or more repair attempts. Different defects don't combine — it must be the same nonconformity.

2. 30-day test

The vehicle was out of service for repair a cumulative 30+ calendar days. Days need not be consecutive.

3. Eight-times test

The vehicle has been subject to 8 or more repair attempts for any nonconformity — this test combines different defects, unlike the three-times test.

4. One-attempt test (safety shortcut)

There has been at least 1 repair attempt for a nonconformity that results in a condition likely to cause death or serious bodily injury if the vehicle is driven, and it continues or recurs. This is Ohio's safety shortcut — and a reason to talk to an attorney promptly rather than waiting for more attempts.

The 5-year filing deadline

Any action under the Ohio lemon law must be commenced within 5 years of original delivery (§1345.75(C)). The period is tolled — paused — from the date you file a complaint with an informal dispute resolution mechanism until its decision.

The certified demand letter

Ohio lemon law claims typically start with a certified demand letter to the manufacturer (per AG guidance): send it by certified mail, return receipt requested and keep the proof. The LemonLawPath $29 packet includes a draft certified demand letter.

How to file: the §1345.77 gate, then court

• Step 1 — the §1345.77 gate: if the manufacturer has an AG-approved informal dispute resolution mechanism and you received timely written notice of it, you must use it before suing. Call the Ohio AG's Consumer Protection Section at 800-282-0515 to confirm whether one applies to your vehicle. It's generally free and not binding on you.
• Step 2 — court of common pleas: if the program doesn't resolve it, claims are brought in a court of common pleas. Filing fees are set per county — check your county courthouse. There is no statutory lemon-law filing fee.

What happens after you file

1. IDR decision — the manufacturer's dispute program decides. It's generally free and not binding on you: if you're unhappy, you can still sue.
2. Court action — a civil action in the court of common pleas with normal court procedure.

Remedies: repurchase, replacement, fees

• Replacement: a new motor vehicle acceptable to you.
• Repurchase: the full purchase price plus all incidental damages (towing, rental, meals, lodging, lender/lessor fees) — the statute provides no usage-offset deduction.
• No usage offset: Ohio's lemon law states no usage-offset formula.
• Attorney's fees — mandatory: a prevailing consumer SHALL recover reasonable attorney's fees plus court costs (§1345.75(A)). Many lemon law attorneys take Ohio cases on contingency — ask how any attorney you contact charges.

When to talk to a lawyer instead

LemonLawPath is for straightforward, DIY-able cases. Talk to a licensed lemon law attorney if any of these apply:

• Your defect is a death or serious-bodily-injury hazard (Ohio's one-attempt safety path — high-stakes);
• You're unsure whether the §1345.77 gate applies to your vehicle;
• The manufacturer denied your claim or disputes the defect;
• Your filing deadline has passed or is under 30 days away;
• Anything about your case feels ambiguous.
