Hertz

Pros: none
Cons: Untrustworthy, rude and overpriced.

Prepaid online (never do this!) for a trip to Ireland but my schedule forced me to return the car several days early and I was told I would not receive a refund for the days even though I told them about the schedule change prior to taking the car. I should have just cancelled the contract - it would have been cheaper. Their website is deceptive and charged my credit card when all I wanted was to reserve a car. The car was smaller than I had requested. I called to complain and the contact was rude and defensive from the beginning and why not, they already had my money. Never again Hertz!

Pros: The car was clean.
Cons: Actual charges higher than quoted
No feedback from the Customer service despite 2 complaints

I booked a car at Glasgow Airport online, with two booster seats for my children. They were supposed to be £15 (for the two of them)for the week, according to the quotation.

But when I received the bill at home, a few days after returning the car, I found out that I had been charged £35 (2 x £17.5) !

Of course, I complained through the Customer Satisfaction Survey I was asked to complete afterwards, but it really looks like the so-called Customer service has no interest at all in my comments... Or maybe it is overstreched due to many complaints ?

I would have appreciate at least some explanations about the billing and eventually to get my money back if, as I assume, a mistake was made.

Pros: Nice cars, low mileage, renting was a snap
Cons: Note everything on the car. Don't rent out of state cars

I rented a Mitsubishi Outlander with Nevada plates in June from Sea-Tac's Hertz.
First the keyfob was broken and held together with duct tape, and the car had some scratches on it.
I took full insurance but when I went to return it a scratch on the front bumper that wasn't noted got me $350.00 poor. Even with the insurance the lady said that because the car had "Out of State" plates it wouldn't cover the scratch because it wasn't noted in Nevada. Also the key fob was fix by my self apparently and I did'nt notify Hertz about the problem. It was busted when i got it.
I'm currently in the process to get my $350.00 back and force Hertz to change their policy and send "out of state" cars back to the state they come from.

Pros: Rented through AAA. They were great and tried to help us.
Cons: Pre-paid car was not available, replaced by smaller car.  Sent coupon as an apology!

We went to Ireland for my son's wedding and rented two cars and pre-paid both.  The first one we picked up with no trouble, but when we went to the airport a few days later with the intention of picking up the second car along with 6 relatives that were just arriving (each car we rented was a van that was supposed to hold 7 people)...they didn't have the car and eventually replaced it with a station wagon, which did not hold all of our guests and luggage. We had to rent taxis to get everyone into Belfast and figure out the rest of the week.  WE asked if they could get us the right car in a day or so and they said no.  When we got home we wrote to complain and they sent us 2 coupons for $25 off a future rental.  The coupons could not even be used together and they had an expiration date. And I am a "Gold" member! 

Pros: Car was clean.
Cons: Long wait, terrible customer service, chaotic return process.

After waiting in line for 30 minutes (and we were next in line!), we came face to face with someone who looked human, but acted and spoke like a robot. It was very disheartening to wait in line for so long and then be treated like we weren't worth speaking to like human beings. It almost felt like we were being hustled, with the representative trying to upsell us on everything, and giving us no time to ask questions during her rehearsed routine. The return process was very confusing and disorganized, although the representative who finally scanned our car was helpful and efficient (once we got him over to our car). Never again will I willingly rent from this company.

Pros: None
Cons: Everything

We rented a car for Ireland and got the minor collision insurance. We should have gotten the full insurance (if that even would have helped). Someone hit the side of our car and made a ding about the size of a walnut. Hertz charged us 1500 for repairs. Some of the outlined charges included; transport fees, paint fees, waste removal, loss of revenue fee, polish fee, final checking fee, parts and tools charge, and MORE! I guess we supplied them with new hammers and nails too!

Absolutely absurd, and we have no way to fight it, we just have to pay it or ruin our credit.

I will never rent from Hertz again.

Pros: Checkin was quick. Car was in good condition
Cons: Thirsty car (KIA Rio 1.4 , 10km/litre), Arbitrary Cleaning Charge

Hertz Rentals provided me and my partner with a small car for a 2 week rental in Portugal. The car was nothing special (A Kia Rio)  and wasn't intended to be. When we returned it , it was dusty and dirty but not excessively so and nothing that the standard inbound car wash would not have dealt with. We had a 40€ (+ tax) "exterior cleaning" charge added to our exit receipt  because we had used it "off-road" (read unsealed road). 
Yes the car was dirty, but its a rental car and they have to expect a reasonable amount of dirt over a 2 week period.
I would never use Hertz again in any part of the world as they have added a cleaning charge for something they would do anyway as normal process and for which they would incur no extra charge. We were not explicitly told that the car had to be cleaned before return and as a premium brand i wouldnt expect it to have to be. Its why I pay a little more, to get professional service. 

Pros: Great customer care
Cons: Sometimes GPS system is not available even when reserved.

I reserved an economy car with GPS for a 2 day long distance trip, but was told by the office that no economy car and no GPS was available. As consolation, they gave me a free upgrade to a Nissan Altima hybrid (which had even better gas mileage than the economy car I had reserved), retained the insurance rates for the economy car, and gave me a 1/2 tank of free gas (equal in value to an extra day's economy rental)! With such great customer care, I will be sure to use Hertz for all my car rental needs.
