it was terrible, but I think Kayak is to blame (not Hertz). In the confirmation email I received from Kayak (or in any of the steps taken when I was booking), it didn't state anywhere that there were limited kilometres in my booking (150km, which was nowhere near enough for the type of trip I was taking). I ended up having to take a different car and pay for everything all over again. To add insult to injury, I tried to contact Kayak to get compensation or at least help for that misleading booking and it proved to be impossible to get in touch with Kayak. I have been an avid Kayak user for 15 years, but not anymore after this. Terrible.
