Do your Minnesota estimates, added-work approvals, and invoices follow the Truth in Repairs Act?

For covered repairs over $100, a Minnesota shop must provide a written estimate when the customer requests one before repairs begin. If a written estimate is provided, charges generally cannot exceed 110% of the estimate unless additional work is necessary, the shop provides a revised estimate, and the customer authorizes continuation. Shops may not charge for unauthorized repairs. For covered motor-vehicle repairs over $50, and for work of any value under a warranty, service contract, or insurance policy, the shop must provide a dated invoice with required repair and charge details. Repair records must generally be retained for at least one year.
