Michigan Compiled Laws, Chapter 257. Motor Vehicles § 257.1326

(a) Require or permit a person to file a statement in writing or otherwise as the administrator determines as to all the facts and circumstances concerning the matter to be investigated.

(b) Mediate disputes between parties arising from violations of this act or an administrative rule.

(c) Develop conditions of probation or operation for the facility or mechanic mutually agreed upon and signed by the facility or the mechanic and the administrator instead of further disciplinary proceedings.

The administrator may not alter the odometer on a vehicle employed in such investigations or deliberately misrepresent the condition of the vehicle.

(e) Conduct mechanical and diagnostic examinations of vehicles when there are reasonable grounds to believe that an unlawful act or practice was used to produce the repair or to make the repair.
