I'm going through the same issue with a rental Expedition I had. I called Hertz when it happened and gave them the SSM number. Since it was a smaller location (Spokane, WA), it was a leasee rental company licensed through Hertz. They sent the vehicle off to a third party repair company who sent me a letter telling me I'm subject to a damage claim. I called them back and they aren't sure how to handle it. I just called the Spokane Ford dealership with the VIN and got told there are no recalls on the vehicle, so they aren't sure how to handle it either. So as of right now, I rented a car, opened the rear hatch on the 2nd day and had it crack, so I had to load my skis through the passenger door the rest of the trip, spent over an hour on the phone with Hertz as of now, and am still as of now on the hook for repair cost. Hopefully with the info from you all, I can get this resolved.
