SIXT Rent A Car is facing scrutiny in Wisconsin for charging customers unlawful fees for vehicle damage. Affected travelers have reported being billed for prohibited administrative and appraisal costs as early as August 2026.
Why it matters
Wisconsin law strictly forbids rental companies from passing on specific administrative, appraisal, or diminution of value costs to customers. Failing to adhere to these regulations risks both legal action and potential lease termination at major transit hubs like Milwaukee Mitchell International Airport.
Travelers have received invoices including prohibited fees, such as one instance of $1,161 in unlawful charges out of a $6,265 total claim. Other documented cases show customers were billed for hundreds of dollars in administrative costs that are illegal under Wisconsin state statutes.
The players
SIXT Rent A Car
An international vehicle rental company that previously settled a 2025 class action lawsuit for $11 million regarding vehicle damage billing.
Hertz
A global rental car provider that does not charge these specific administrative and appraisal fees within the state of Wisconsin.
The details
SIXT processes damage claims by issuing invoices that include charges for diminution of value, administration, and appraisal costs. These claims are frequently sent to renters several days after the vehicle has been returned to the rental location. While some claims against specific customers have been dropped, others have moved to debt collections, highlighting the discrepancy between company billing and state consumer protections.

The Home Front
These rental billing disputes arrive as Wisconsin state regulators continue to monitor compliance with consumer protection laws regarding vehicle damage claims. The situation follows a pattern set by the 2025 SIXT Rent A Car $11 million class action settlement.
If you receive a damage invoice from a rental agency, review the bill closely for prohibited items like administrative, appraisal, or diminution of value fees. Disputes regarding these charges can be submitted for review through the Wisconsin Bureau of Consumer Protection complaint portal.
The takeaway
Travelers in Wisconsin should remain vigilant regarding the itemized fees on any post-rental vehicle damage invoice. Keep copies of your rental agreement and any pre-existing damage documentation, and do not hesitate to challenge fees that fall under prohibited administrative or appraisal categories.
