Poor customer service and car experience. When we arrived, they spent about 45 minutes finding and preparing a car for us, even though it had been reserved for months. The car was an older Nissan Altima with minor dents and scratches. They had the reservation, but apparently don't prepare cars in advance, just deal with customers as they arrive.
Leaving the lot, a few blocks away, we noticed a warning light and that the brakes were squeaking. figured out the warning light was windshield fluid - not a big deal as we could pick some up, but thought Hertz was better than that? Figured the brakes might be squeaking due to dust, moisture, etc.
Unfortunately, the brakes didn't improve over time, so we called them several days later to swap the car. They told us they had two new Camry's to swap with and to bring it in and we could swap with one of those. When we got there (an hour later), the girl at the stand (after taking two phone calls while we were waiting) said that they only had a smaller car that they could give us, and couldn't give us one of the Camry's as they were reserved. She thought the brakes might be "dusty" without checking the vehicle, even though we told her they were squeaking consistently and loudly. So we drove all that way from North Scottsdale based on the phone call only to leave with the same vehicle. She really didn't care that the brake linings might need replacing, or about our experience driving around town annoying people with the brakes.
I'd been an Avis customer for many years, thought I'd try Hertz this time for a long-term rental. Big mistake.
