I used Hertz through my insurance company when I got into an accident and my car was getting repaired. I had no issues with them until I got my bill. They did not disclose that the limited waiver liability insurance they upsold me was not covered by my insurance. I had to pay 100% of that which was an extra $250 tacked on to my rental car bill. I found out later that State Farm covers the exact same thing that the limited waiver liability covers. The Hertz rep also said that State Farm "highly" recommends getting this coverage. Let me tell you, that is a load of BS. I called in and spoke with a rep and asked to speak to a manager. I left a message with the rep as the manager was busy. Never got a call back. Hmm...I wonder why.
The only positive experience I had with Hertz through this debacle, was that I was able to drop off my car at Gerber Collision when I picked up my baby so I didn't have to catch a ride to drop off the rental. This was the only thing that gave them a 1 star. I may update my review if the manager ever calls me back.
