Posted by Nathan DeLadurantey | Oct 02, 2023

When you purchase a vehicle in Wisconsin, you expect a fair and transparent transaction from the dealership. However, if you encounter issues with your purchase or feel that the dealership has engaged in unethical or illegal practices, it's essential to know how to file a dealer complaint with the Wisconsin Department of Transportation (WisDOT). In this blog post, we will provide you with a step-by-step guide on how to navigate this process and ensure that your concerns are properly addressed.

Having a complete record of your transaction will help you clearly articulate your concerns to WisDOT.

Step 2: Contact the Dealership

Before taking formal action, it's a good practice to attempt to resolve the issue directly with the dealership. Contact them to discuss your concerns and provide an opportunity for them to address the problem. Keep records of your communications with the dealership, including dates, times, and the names of the individuals you spoke with.

Step 3: Visit the WisDOT Website

Wisconsin Department of Transportation has an online portal where you can file a dealer complaint. Visit their website ( to access the complaint form.

Step 4: Complete the Complaint Form

On the WisDOT website, locate and complete the dealer complaint form. You will need to provide detailed information about your complaint, including:

Step 5: Submit the Complaint

Step 6: Follow-Up

After submitting your complaint, you may receive an acknowledgment from WisDOT. Keep records of all correspondence related to your complaint, including any reference numbers or case IDs provided.

Step 7: Be Patient

WisDOT will review your complaint and investigate the matter as appropriate. The process may take some time, so be patient during this phase.

Step 8: Attend Any Required Hearings

If WisDOT determines that a hearing is necessary to resolve the issue, be prepared to attend and present your case. Bring all relevant documentation and be ready to explain your concerns.

Step 9: Await a Resolution

After the investigation or hearing, WisDOT will provide a resolution or decision regarding your complaint. This may include actions such as issuing warnings, fines, or even revoking the dealership's license if necessary.

Step 10: Seek Legal Advice (if necessary)

If you are not satisfied with the outcome or believe your concerns were not adequately addressed, consider seeking legal advice from an attorney who specializes in consumer protection or automotive law. They can help you explore your legal options.
