Don't let them give you a silver Opel Astra at Warsaw Airport!! The actual pickup etc went very smoothly. However, when driving out of the car park I noticed the orange engine management light was on. I stopped and told the young lady who handed me the car. She said to ignore the light as it is a factory fault and the car was fine to drive. 10 minutes into the journey I was having real problems getting the car into gear and the clutch was very "sticky". I decided that I would drop my wife and 2 young daughters off at the hotel then go back to swap the car as it really wasn't performing. However, I got to traffic lights, I was in the middle of 3 lanes of traffic. The car began to shake violently. The car would not go into gear and then completely cut out. I tried the engine 3 or 4 times but when it did start I could not force it into gear. Having 2 young kids in the car they became quite scared as we were sitting ducks. We called the emergency number, got out the car and removed all our luggage and waited for help. It took almost 2 hours for the replacement car to arrive with lots of apologies. I have since sent them an email to say how upsetting the whole experience was. However, the reply didn't even contain an apology. They actually told me that there was nothing wrong with the car and they hired it out to another customer. Can you believe that??? I hope the next customer isn't in the fast lane of the motorway when it breaksdown again, they might not be so lucky!! They're playing with lives!!
Das Fahrzeug wurde im April über die Fluggesellschaft gebucht und mit der Kreditkarte bezahlt. Vor Ort mussten wir die Kaution hinterlegen und die Kreditkarte war nur 5 statt wie im Kleingedruckten auf der Seite 3 hingewiesen 6 Monate gültig. Alle anderen Möglichkeiten wurden abgelehnt und uns wurden 560.- Euro für eine Zusatzversicherung aufgezwungen. Nie wurde darauf hingewiesen was eher Täuschung und Geschäftsmodell ist. Man muss auch vor Ort nochmals ein Papier ausfüllen, dieses dient eher für die Provisionbeweis der abgezockten Touristen. Auf dem Zusatzvertrag der Versicherung war bereits alles vorausgefüllt, sie wussten schon das es hier was zu holen gab. Ganz miese masche von der Swiss unterstützten Carunion
Auto Union Greece (Preveza Airport)- would definitely use again. We were told to expect someone waiting with a sign on arrival - we couldn't find him for 10 mins which sent alarm bells ringing, however on calling the office they said to walk across the road and minibus would be waiting for us, which it was. This was the only negative experience we had. The transfer to their office is 1 min away. Our car was ready and waiting , we checked over and completed paperwork and all was fine. Drop off was quick and easy. They had minibus waiting to transfer us back.
Slechtste auto verhuur ooit. Huur hier nooit een auto. De autoverhuur is slecht vindbaar. Bij aankomst hebben we een uur moeten wachten omdat de capaciteit niet op het aantal huurders berekend was. De auto die we meekregen maakte een absurd klapperend geluid dat vanuit de motorruimte kwam. AutoUnion was niet bereid naar ons toe te komen om het probleem op te lossen. In plaats daarvan hebben we een halve dag opgeofferd om terug te gaan naar autoUnion. Het mankement aan het voertuig is goed te verklaren. De verhuurder maakte een testrit waarbij hij de auto zo belachelijk ruig bestuurde dat geen auto het langer dan een jaar zou overleven. Bij het afleveren van de auto was de verhuurder zeer agressief en onbeleefd. Omdat er wat vervuiling door bezoek aan lokale stranden in de auto lag nam hij €50 euro van de borg in beslag. Aan de manier waarop dit kenbaar gemaakt werd blijkt dat dit spelletje vaker gespeeld wordt en dat ze op deze manier extra inkomsten proberen te genereren.
I would stay clear of AutoUnion - Bergamo airport. The staff was rude and they have terrible communication within the company. We changed the name of the main driver long before we arrived (through a broker who notified AutoUnion). The headquarter, or what we should call it, never changed this in their papers, leading to us not getting the car we had already paid for. No one was able to reach the office, and the staff at the car-providet desk didn’t really do anything to help here and were just rude. I sat on the phone trying to reach the «headquarter» for AutoUnion for hours without anyone picking up the phone. Terrible experience overall and wouldn’t recommend this company to anyone.
⭐ 1-star Warning: Avoid AutoUnion Thessaloniki – Hidden Damage, Lies, and Forced Charges We had a terrible experience with AutoUnion Thessaloniki and feel compelled to warn others. When we picked up the car, we were only given the spare key—no remote. This meant we had to unlock the car manually every time, which already seemed odd. On the first evening, the door lock was stiff and difficult. A few days later, the lock stopped working entirely. When we contacted AutoUnion, they refused to help and instead blamed us—claiming we had caused the damage—and demanded we pay for repairs. We then went to a local garage, where a certified mechanic confirmed the lock had been worn down over time, likely from overuse of the spare key. It was clear the issue was not caused by us. AutoUnion then claimed the car was only a year old. This was a lie—we later found the registration papers, which clearly showed the car was first registered in 2022. This entire situation felt like a scam: ✔️ Give customers a car with pre-existing mechanical wear ✔️ Blame them when it fails ✔️ Demand unjust compensation (500 euro) ✔️ Lie about the age of the vehicle to cover it up It’s clear this company is not interested in honest business. They offer cheaper rentals up front but seem to make money by charging customers for worn-out parts they didn’t damage. Do not rent from AutoUnion Thessaloniki. They are dishonest, unhelpful, and quick to exploit their customers. Don’t be a part of their scam business.
This is my second time renting from AutoUnion, and once again, the experience was excellent. All the staff are very nice and extremely helpful. Because they remembered me from my previous reservation, they didn’t charge me extra or block any deposit, which I appreciated. They truly care about their customers — they even drop people off at the train station and give tips to help save money. It was very touching to see how much they go out of their way to help. An amazing place to rent a car with top-notch service!
**Subject: Formal Complaint Regarding Car Rental Experience in Rome** Dear Sir/Madam, I am writing to formally file a complaint regarding a highly disappointing and distressing experience I had with your car rental service during my recent trip to Rome, Italy. Upon our arrival at your rental office in Rome, we were informed that the small car we had reserved was not available. Instead, we were offered a different vehicle but only on the condition that we pay an additional €360. After a long and exhausting flight, we felt we had no real choice but to accept the offer — however, the entire interaction felt like a manipulative and unfair negotiation. More disturbingly, we were met with sneering remarks and what appeared to be discriminatory behavior from your staff, possibly due to our nationality (Israeli). Their attitude was one of complete indifference and disrespect. The employee filmed the vehicle upon handover, yet when we returned the car a week later, we were accused of causing a scratch on the wheel — something we strongly deny responsibility for. When we requested to review the initial video, we were denied access. Furthermore, the return form had been signed in my name without my presence or consent. This entire experience was not only unpleasant, but it felt hostile and dishonest. I have rented cars worldwide — this year alone I have spent 153 days abroad — and I have never encountered such mistreatment. Additionally, we were forced to pay another €300 under the claim that we had not upgraded to maximum insurance coverage, which we were never properly informed about. I am reaching out to you in good faith before taking further action, including public disclosure via social media. This is not a threat, but a genuine concern aimed at exposing and preventing fraudulent practices and customer exploitation. I trust you will take this complaint seriously and look into the matter thoroughly. ---
Molto gentile e efficace la signora che ci ha preso al terminal portati in ufficio e consegnato la macchina, idem al ritorno, rimborso della cauzione immediato sulla carta, grazie
My experience with AutoUnion - Kalamata was extremely disappointing, and I do not recommend this company. Upon arrival at Kalamata Airport, no one was holding a name sign as promised. I had to search for the driver for over an hour and only found him by chance. The car was not ready, and we had to wait an additional hour and a half without any apology or compensation. The vehicle itself was very old, worn-out, and far from comfortable or safe. Sadly, the car became the nightmare of our trip and had a negative impact on our entire experience in Kalamata. Avoid this company and look for more professional and customer-oriented alternatives.
Arbeitet in Sibiu / RO leider mit price cars zusammen - und unsere Erfahrung ist genauso schlecht wie deren Bewertungen. Fahrzeug mit ca. 55.000 km bekommen, lange Schramme gut sichtbar an der linken C-Säule und fotografiert. Bei Rückgabe geht der Mitarbeiter zielstrebig zum rechten Vorderrad und zeigt eine Schramme in der Felge... In der Schadensrechnung, die wir per Mail bekamen, waren auf einmal mehr Unterschriften, als wir bei Übernahme geleistet hatten. Jetzt warten wir seit 4 Wochen darauf, dass die Versicherung diesen "Schaden" von 420 Euro zahlt. Nachtrag: Nach 6 Wochen wurde die einbehalten Schadenssumme erstattet.
Do not rent from autounion in Milos. Literally the worst customer experience of my life. It was so bad, I feared for my safety. The employees acted like thugs and extortionists after I had a minor accident. The car they gave me had almost 90,000 hard miles on it. The clutch was so worn it struggled on hills and the gears ground when shifting. It had obviously already been in at least one other accident and been driven into the ground on the island's rough roads. Wish I had looked into them before I booked. Other people have had similar experiences. Read the reviews. Do yourself a favor and rent from a more reputable company. My subsequent experience with Milos Rent Car by Tourlakis was like night and day. Safe car, professional staff.
I've rented a car in Sofia beginning of April. The service was not too bad,but first thing they changed 70 euros because I didn't have a credit card. But worse problem they didn't refund the security deposit back. Worse experience I had before.😡😡😡 Highly not recommended.
Disappointing Service and Vehicle Experience The service at AutoUnion left much to be desired. The staff were unwelcoming, with no smile or warmth, which set a negative tone for the start of our holiday. I did not receive the vehicle I had booked. The vague promise of “or similar” resulted in a minibus that felt more like a utility van with civilian seats bolted in—far from what I had expected. To add to the frustration, the fuel gauge showed only a quarter tank, despite the rental agreement specifying a half tank. Since when did a half tank become the standard, or am I missing something? I voiced my concerns, but the team showed no willingness to acknowledge the issue or offer any resolution. Their dismissive attitude made it clear that customer satisfaction wasn’t a priority. In the end, my family tried to make light of the situation by jokingly naming the vehicle “the love van,” but it was, unfortunately, a disappointing experience overall.
Zeer goede ervaring met Autounion in Kreta. Kantoor vlakbij aankomsthal van de luchthaven Heraklion. Auto stond klaar. Mooie propere wagen met slechts 28000 km. Papierwerk was snel geregeld. Personeel was zeer vriendelijk.
To rent and return was the worse experience. The guy at Malpensa airport is sooo rude and I wonder how you guys here someone like him
Alt gik hurtigt og smertefrit. Flink repræsentant. Ingen ekstra udgifter.
The employee Lukas at Bratislava airport is excellent! He helped us a lot with everything we asked him for. Even though the plane was delayed, he waited for us and served us with kindness and patience. He even offered to get us the vignette to travel to Austria, because we didn't know. Finally, on an issue that arose, he helped us a lot.The customer service of Auto union via email is excellent, as is the car we rented. I highly recommend choosing the specific company, especially the office at Bratislava Airport.
I had an extremely disappointing experience with AutoUnion Car Rental during my trip to Bulgaria in December 2024. The vehicle provided suffered a technical battery fault, leaving us stranded. Despite AutoUnion’s policy stating that roadside assistance for technical issues is included, their local representative refused to help, forcing me to pay out of pocket for third-party towing. To make matters worse, AutoUnion has since refused to reimburse these emergency expenses and has not returned my deposit, which has been overdue for several months. Multiple attempts to contact them have been ignored, and they have refused to escalate or resolve the matter. This lack of accountability and customer support is unacceptable. I’ve now escalated this case to the European Consumer Centre. I strongly advise others to be cautious when considering this company.
