I’m also a long-term customer of Hertz. Recently I had TWO horrible experiences with them, albeit overseas at Nice (NCE) airport. I I travel to Nice frequently. For two consecutive rentals (several months apart) I was cited damage on a rental. Provided proof that the damage was not mine, still received invoices for the damage. Months later the claim was finally settled (at no cost to me). It was referred to the claim service in the US which seems to be completely incompetent.
No more Hertz for me. Ever.
