Ohio Rev. Code § 4549.45: Written notice of tampering or nonfunction.

(A) No person shall transfer a motor vehicle if the person knows or recklessly disregards facts indicating that the odometer of the motor vehicle has been changed, tampered with, or disconnected, or has been in any other manner nonfunctional, to reflect a lesser mileage or use, unless that person gives clear and unequivocal notice of the tampering or nonfunction or of the person's reasonable belief of tampering or nonfunction, to the transferee in writing prior to the transfer. In a prosecution for violation of this section, evidence that a transferor or the transferor's agent has changed, tampered with, disconnected, or failed to connect the odometer of the motor vehicle constitutes prima-facie evidence of knowledge of the odometer's altered condition.

(B) Except as otherwise provided in this division, whoever violates this section is guilty of transferring a motor vehicle that has a tampered or nonfunctional odometer, a felony of the fourth degree. If the offender previously has been convicted of or pleaded guilty to a violation of this section, any provision of sections 4549.42 to 4549.44, or any provision of section 4549.451 or 4549.46 of the Revised Code, transferring a motor vehicle that has a tampered or nonfunctional odometer is a felony of the third degree.
