The maximum number of days that a repair shop can charge storage fees on a repaired auto depends on the laws and regulations of the specific jurisdiction where the vehicle is located. It can vary from state to state or country to country. In some jurisdictions, there may be specific laws or regulations that set a limit on the number of days that a repair shop can charge storage fees for a repaired vehicle. For example, some states may limit the storage fee period to a certain number of days after the owner is notified that the vehicle is ready for pickup.
Additionally, some vehicle-related consumer protection laws or regulations may require repair shops to disclose any storage fees in advance and obtain the owner's consent before starting the repairs. To determine the maximum number of days that a repair shop can charge storage fees for a repaired auto in your specific jurisdiction, it is recommended to consult with local consumer protection agencies, automotive regulatory bodies, or legal professionals to get the most up-to-date and accurate information regarding the applicable laws and regulations.
