If you have a complaint with a repair facility or a vehicle dealer, talk to the owner or manager. When you bring a problem to the manager's attention, you may be able to work out a settlement.
If this does not resolve the problem, you may contact the Regulatory Monitoring Division, Bureau of Information Security (BIS), Michigan Department of State at 1-888-SOS-MICH (1-888-767-6424). You may also file an Automotive complaint online. Jurisdictional complaints involving motor vehicle sales or repairs are routinely investigated by BIS;
You must file a complaint using the printable Consumer's Automotive Information & Complaint Kit; (PDF Format) or the Online Automotive Complaint Form, accessible at the bottom of the page;
If you believe you were charged for repairs that were not done or were told you needed repairs that you later found out were not needed (even if you did not have the repairs done), contact BIS immediately;
If you have not received your title and registration within three weeks, contact BIS;
