When Is a Car a 'Lemon' in Ohio?
Ohio Lemon Law defines a lemon as a vehicle with a substantial defect the manufacturer can't repair after a reasonable number of attempts within the 12-month/18,000-mile window.
The short answer: a vehicle becomes a “lemon” under the Ohio Lemon Law when the manufacturer has had a reasonable number of attempts to repair a substantial defect — within the 12-month / 18,000-mile window.
The legal test
Under Ohio Rev. Code § 1345.72:
- Substantial impairment of use, value, or safety.
- Reasonable number of repair attempts.
- Personal, family, or household use.
- Within 12 months / 18,000 miles.
What counts as a “substantial” defect
See qualifying defects for common categories.
What counts as a “reasonable number of attempts”
- One attempt to repair a serious-safety defect (likely to cause death or serious injury), OR
- Three or more repair attempts for the same defect, OR
- Eight or more attempts for any combination of defects (Ohio-unique), OR
- 30 or more cumulative days out of service.
The 12-month / 18,000-mile window
Slightly broader mileage threshold than IL or PA.
How do I know if my car qualifies?
- Multiple repair visits for the same defect.
- 30+ days out of service.
- Manufacturer offering goodwill payments.
- Within the 12-month / 18,000-mile window.

What if you’re past the window?
CSPA (2-year limit) and Magnuson-Moss (4-year limit) may still apply.
