i had service last month and required a loaner car. Given a hertz loaner at tysons service center. Had an easy pass in the car and told I could access it without any warning of fees. I had the car for two days and used it once for a ONE dollar toll. Billed 15.85 dollars for the toll and "administrator fees". I fully expected to pay the toll. I did not expect additional markup of 14.85 for the use. Tesla obviously has no problem with this by using hertz cars. They can certainly at a minimum warn you. I am great full the service was only two days since a single toll use generates the administrative fee for everyday the car is rented. BEWARE
