(1) In the event that:
(a) The written repair estimate contains only an estimate for diagnostic work necessary to estimate the cost of repair and such diagnostic work has been completed;
(b) A determination is made by a motor vehicle repair shop that the actual charges for the repair work will exceed the written estimate by more than $10 or 10 percent, whichever is greater, but not to exceed $50; or
(c) An implied partial waiver exists for diagnostic work, as described in s. 559.905(5), and such diagnostic work has been completed,
the customer shall be promptly notified by telephone, telegraph, mail, or other means of the additional repair work and estimated cost thereof. A customer so notified shall, orally or in writing, authorize, modify, or cancel the order for repair.
(2) If a customer cancels the order for repair after being advised that a repair which she or he has authorized cannot be accomplished within the previously authorized estimate, the shop shall expeditiously reassemble the motor vehicle in a condition reasonably similar to the condition in which it was received unless:
(a) The customer waives reassembly, or
(b) The reassembled vehicle would be unsafe.
After cancellation of the repair order, the shop may charge for the cost of teardown, the cost of parts and labor to replace items that were destroyed by teardown, and the cost to reassemble the component or the vehicle, provided the customer was notified of these possible costs in the estimate prior to commencement of the diagnostic work.
(3) It shall be unlawful for a motor vehicle repair shop to charge more than the written estimate plus $10 or 10 percent, whichever is greater, but not to exceed $50, unless the motor vehicle repair shop has obtained authorization to exceed the written estimate in accordance with subsection (1).
(4) It shall be unlawful for any motor vehicle repair shop to fail to return any customer’s motor vehicle because the customer has refused to pay for unauthorized repairs or because the customer has refused to pay for repair charges in excess of the final estimate in violation of this section.
(5) Upon request made at the time the repair work is authorized by the customer, the customer is entitled to inspect parts removed from her or his vehicle or, if the shop has no warranty arrangement or exchange parts program with a manufacturer, supplier, or distributor, have them returned to her or him.
