  Deceptive Charges, Dishonest Practices, and Shameful Customer Service My experience with SIXT was incredibly disappointing and raised serious concerns about the company's honesty, transparency, and business practices. During the rental process, the agent at the counter misrepresented the additional charges being applied to my rental and the reasons for them. I only discovered the discrepancies after reviewing my final invoice. When I contacted SIXT to address the issue, I was assured they would investigate. Instead, the company failed to follow up, provide any explanation, or remove the disputed charges. After receiving no meaningful resolution, I escalated the matter to my credit card company, which supported disputing the charges. Rather than acknowledge the concerns or attempt to resolve the situation professionally, SIXT responded with threats and continued to defend what I consider deceptive and dishonest practices. What should have been a straightforward rental became an unnecessarily frustrating experience involving misleading information, questionable charges, nonexistent accountability, and adversarial customer service. I strongly caution others to carefully review every charge, question anything that seems unclear, and document all interactions. Based on my experience, I cannot recommend SIXT and will not be renting from them again.

  Very disappointing first experience with Sixt, particularly their customer service and handling of an issue that never should have occurred in the first place. After my rental, I was incorrectly associated with a traffic camera violation in Des Moines, Washington. The problem? I wasn't even in Des Moines at the time of the violation. The traffic photos showed a black Toyota, which was clearly not the white Mercedes I had rented from Sixt. Despite this obvious discrepancy, Sixt initially told me they had reviewed the matter and found no discrepancies. It was only after I went through the trouble of providing my own evidence, including location history, credit card transactions, and a timestamped photo proving I was elsewhere, that they finally acknowledged the mistake. Even then, I had to repeatedly follow up to understand whether the matter had actually been resolved. Their eventual response was that they had requested the violation be transferred back to the rental agency, without providing definitive confirmation that the matter was closed. And I'm just supposed to take their word for it when they couldn't tell black from white? I specifically requested some form of confirmation from the police department that I was no longer associated with the violation. That seems like a reasonable request when I'm holding a physical citation mailed to me by the police. Instead, Sixt's response was: "For any confirmation you may need, feel free to contact the Des Moines Police Department." What bothers me most is the complete lack of ownership throughout this process. I was forced to gather evidence to prove something that should have been obvious from the start, and even after Sixt acknowledged the error, they left it to me to verify that the situation had actually been resolved. At no point was there any meaningful acknowledgment of the time, inconvenience, or stress this caused, much less any effort to make things right. I enjoyed the vehicle itself, but this experience has left me with very little confidence in Sixt's attention to detail or ability to handle problems when they arise. Not a great first impression, and certainly not the level of customer service I'd expect from a so-called premium rental car company.

  Over the past few years, I’ve rented all kinds of cars from different rental companies, so I’ve had quite a few experiences to compare. 🚗✨ SIXT at Seattle Airport consistently gets really good reviews, and a coworker recommended booking through another website because the prices can be even better. So… I figured I’d give it a try! 👀 Before picking up the car, I had already completed the driver’s license and personal information verification through the SIXT app. 📱✅ Since it was my first time using the app, there was also a free upgrade option, with the possibility of getting a BMW X1 or X2. 🚙✨ At the counter, they also offered upgrades, saying something like, “Normally it’s this much, but today you can upgrade for just $25/day.” 😂 But I was thinking… if the app can offer a free upgrade, why wasn’t the same option available at the counter? 🤔 I’m still a Silver member, so I had to complete the rental check-in at the counter. After checking in, the app automatically selected an available vehicle that matched my rental. 📱🚗 And this time, I ended up with something I’d never driven before — a Volvo XC40! 🇸🇪🚙 It’s a relatively compact SUV, but honestly, it was more than enough for driving around the city and even making a day trip up into the mountains. It was comfortable, easy to handle, and really smooth to drive. 👌⛰️ Overall, I was really impressed with the service at the SIXT counter. 🙌 Definitely a great first experience, and I’d happily rent from SIXT again on my next Seattle trip! 🚗☁️✨

  This rating is intended to reflect our experience with customer service after returning our vehicle. Prior to the vehicle return, our experience in early September 2026 at the Sea-Tac location was very good. We have no complaints and found it to be similar to what we generally expect at SIXT, having used them many times in multiple locations in the USA and Europe over the last ten years. The problem concerns an item that had been left behind in the vehicle. The item, Air Pods (in case), was discovered missing within two hours of the vehicle’s return. We were able to see the item’s location, so it made sense to us that if we could connect with someone at the Sea-Tac rental facility, we could notify them and make the necessary arrangements to get the item returned. Two frustrating (for various reasons) calls to customer service could not do that; they could only tell us to fill out the online form and nothing more. Why can’t they connect us with the Sea-Tac office and/or have someone from the office call us? We filled out the online form, which did not permit us to attach images showing the item’s location (this is a missed opportunity to help customers). The following day, we filled out a general purpose form that did permit us to attach images, so we provided item’s current location. At that time, the item was located offsite from the rental car facility but near the airport, which is where it had been the evening before. Within a few days, the item was no longer transmitting its location. Our assumption is that it was located by a SIXT employee that knew there were Air Pods in the car and reset them. Just under three weeks later, we received an email from SIXT stating they could not locate our missing item. That was the first time we heard from SIXT after submitting the form. Customer service was completely ineffective and inefficient in this instance. From our point of view, this was a very easy problem to solve especially since we knew where the item was. SIXT seemed to have no interest in even attempting to assist us. Doing so would have made SIXT look very good; instead they felt it was better to lose a decade-long customer.

  The price was good and the car was fine. I rented a car until 6pm and returned it sometime between 5:50 and 6:10 - I didn't note the exact time, as that small grace period has always been an industry standard in my experience. SIXT recorded the vehicle as returned after 6:30 and charged me for an additional hour (more than 10% of my daily rental charge). When I contacted customer service, they admitted that they could not provide documentation of the time of return and refunded the additional charge "as a goodwill gesture." Especially as an airport rental, where customers may be more concerned with making their flight than documenting the exact time they arrived at the rental facility, it's concerning that people are facing extra charges based on a recorded return time that SIXT apparently cannot substantiate. This experience will certainly be enough for me to pay a few extra dollars with a reputable rental service in the future.
