Bad Treatment

I have been a loyal Sixth renter until our last experience in Warsaw, Poland. Never again.
We came back to the same place two years later with the exact same document (international driving document) that was previously accepted by Sixth. This time I was told that what we have is a scam and if we want to rent a car we need to purchase additional insurance in amount about $670. I wrote emails to customer service but nobody responded. Absolutely bad treatment.

Disgusted with Sixt – Misleading Charges and Unfair Billing

Title: Disgusted with Sixt – Misleading Charges and Unfair Billing

I’m extremely disappointed with my recent rental experience with Sixt and feel completely misled and overcharged.

Insurance Scam:
Despite purchasing full insurance online through Booking.com before picking up the car, the Sixt representative at the Lanzarote location falsely claimed no insurance had been bought. I was pressured into accepting another "full insurance" package on the spot for what I was told would be around €68. Instead, I was charged a shocking €326.40 for something called "All Inclusive Protection." I was told that €300 of this would be a refundable deposit — something that was not clearly explained and has only led to further confusion and frustration. I've received multiple invoices with different amounts, none of which make the billing any clearer.

Thankfully, after contacting Booking.com and showing them proof of my original insurance purchase, they refunded the policy I had bought online. But that doesn't make up for the misleading upsell and excessive charge at the Sixt counter.

Unexpected Charges:
The only additional cost I had agreed to was a car upgrade fee of €14.85 per day. Aside from the €236.42 already paid via Booking.com, I was then charged an outrageous €572.05 directly by Sixt, bringing the total to €808.47 for 8 days!!!— far more than I had expected or agreed to.

This experience has left a sour taste, and I feel like I was deliberately misinformed and taken advantage of. The entire process was disorganized, the billing is opaque and misleading, and customer service has been dismissive at best.

I will not be using Sixt again and would strongly caution others to avoid them — especially at Lanzarote.

Avoid Sixt Dublin Airport

Avoid Sixt Dublin Airport – Misleading Charges & Terrible Customer Service!

I had an extremely frustrating and disappointing experience with Sixt Dublin Airport, and I want to warn others before they make the same mistake.

When I picked up my rental, I requested a diesel automatic version of the SUV I had originally booked. At no point did the desk representative, Louise, inform me that this would result in an additional charge of hundreds of euros. Had I been made aware, I would have declined the automatic option, just as I did when I was told adding my daughter as a driver would cost an absurd amount extra. My daughter was with me at the counter and can fully confirm that no mention of an upcharge was ever made.

On top of that, I was misled about the fuel charge. The agent signed me up for prepaid fuel without giving me the option to return the vehicle full. In fact, she claimed that this is what makes Sixt “different” from other rental companies. I later learned this is untrue—many rental companies allow customers to return the car with a full tank. As a result, I was charged a staggering €104 for a full tank refill, even though I returned the car nearly half full! This was never properly explained, and it feels like an intentional way to squeeze more money out of customers.

When I contacted Sixt customer service, they refused to take responsibility and dismissed my concerns outright. Their response? “You signed for it”—despite the fact that key details about additional charges were never disclosed at the counter.

Sixt’s refusal to address their misleading practices, hidden fees, and unfair charges shows a complete disregard for customer service. I visit Ireland frequently and have rented from many other providers at Dublin Airport without issue—this was my first and definitely my last time renting from Sixt.

Sixth Bologna Aeropurto Airport

Generally my family have had good experience when booking hotels and cars via Booking.com.
Therefore we made "rent a car" booking via Booking in order to be sure, that we get good travel security and service abroad in Italy. My daughter and myself made the order via Booking web site.

We should have a short holiday in Italy and Lajatico (Andrea Bocelli 30 years concert) in July 2024 - from Monday to Friday.

Since we are a family - parents and 3 daughters - we wanted to find a well-known car rental company, which has cars big enough to take us all in the same car included our 5 luggages. We ended up to rent a car from Sixth via Booking, since they had adverts on website saying, that Sixth had a car type which had place for 5 people including their 5 luggage. The total price for 5 days was stated to be about 400 euros + extra insurance fee if wanted.

When we arrived with flight to Bologna Airport on Monday evening in July and should pick up our car, we got a huge surprise. The Sixth representative at the service desk in the Airport Hall (together with his collaguees standing next to the desk) just informed us that the car we had rented, could not take us and our luggage’s - no space enough at all!

We were desperate and short of time of course in the evening. We had to use about two extra hours going back and forth to the Sixth parking garage area and Sixth service desk in the Terminal building in the extremely hot airport. It was necessary for ut to decide that evening which car we could use instead to drive further that night. We did not have a choice - no time for other arrangements...

This was highly stressful for us all and really not a good start for our holiday - when desperately trying to get e vehicle which had place for our family.
(And to be honest, there are very many car types and models in this world which have place enough for a travelling family of 5 persons.
Sixth had clearly given non correct information on Booking sites regarding their cars and their capacity).

Finally, after trying different car models that night we found one which could take us - but first we had to empty one luggage and repack - and throw away one luggage! And then we could start our holiday - many hours delayd).
BUT WE HAD TO PAY DOUPLE THE PRICE FOR THE CAR WHICH HAD SPACE FOR US. THE PRICE WAS UNBELIEVEBLE. This car rental price ended up to be the biggest single bill we had to pay during this holiday.

In the meanwhile - happily we had a fantastic Bocelli concert in Lajatico and nice days in Italy with good friends and friendly Italians.

We returned - as originally planned - from Lajatico to Bologna Airport on Friday afternoon, exactly at the time which we had given in beforehand.

But the story continues:
After we had come home from holidays, Sixth sent us email writing that they had found a damage - a little scratch - in front of the car. We could not recognize this damage. We had been driving carefully and parked in the countryside with a lot of space.
We were released and happy to have booked via Booking a full scale insurance to this rental period. We got the refund for this claimed damage.

Summa Summarum:
We do not recommend to rent a car from Sixth in Bologna.
I am sure there are many other good alternatives in Bologna.

Super comfy car and helpful staff

I rented a KIA carnival latest model for two days family holiday and I found this car is super comfy for both driver tondriver and passengers to sit longer time. The most important thing Sixth Albury team is super friendly and helpful. Again I will rent car from them when I need.

Incorrect damage claim months after car return

I rented a car at Sixt at Nice Airport, and after the 5 days I drove it returned the car. A man was there to ask me if all went well, which I confirmed, and went towards the transportation to the other terminal.
4 months or so later, I receive an email reporting damages to the car. There was no damage, and nothing was reported to me when I returned the car. I booked the car through Autoeurope, and have then also booked the refund for any claims, so the full cover. I sent several mails in reply to Sixt saying that I did not accept the damage claim, of which they informed me so late that they could not charge my credit card. As reply the last 2 emails I asked them to call me. This has never happened.
Today I got an email from a debt collecting agency., where interest and costs were added. To avoid the further hassle I paid the invoice, which was for €413,32.
Not the amount, and I will get this back through the collision waver cover I booked, probably except for the cost and interest they charged of €31.11.
It's the principal.
I rent several cars a year, but will never rent from Sixt.
The company is dishonest.
