I do not recommend SIXT based on how a post-rental issue was handled…read more I rented a vehicle in Munich and specifically selected and paid for cross-border authorization because I planned to travel into Austria. In addition, I purchased a valid Austrian digital vignette for the vehicle's license plate prior to entering Austria. The vignette confirmation clearly shows activation on 24.01.2026 at 14:22. The alleged toll event cited by SIXT occurred on 25.01.2026 at 13:44 -- well within the validity period. Weeks after the rental, I was charged €200 for an Austrian "substitute toll." I provided SIXT with the digital vignette documentation showing the plate number and activation timestamp covering the alleged violation. Their response was that they "do not check whether the fine is legit or not and act according to the information provided by the relevant authority." In other words, there was no substantive review of the documentation provided. The toll authority invoiced SIXT as the registered owner of the vehicle. SIXT paid the assessment and passed the charge through to me without evaluating whether toll coverage was active. When I asked that they review the documentation or address the matter directly with the authority as the registered owner, I was told to appeal it myself. This experience raises concerns about transparency and dispute handling. When customers pay additional fees for cross-border travel and independently purchase toll compliance, it is reasonable to expect documentation to be reviewed before a penalty is passed through. The vehicle itself was fine. The issue is the post-rental handling and unwillingness to engage in meaningful review when clear documentation was provided. If you are renting in Europe -- especially crossing borders -- make sure you understand exactly how toll issues are handled and get everything documented. Based on this experience, I would not choose SIXT again.

From a corporate travel perspective, this was not handled appropriately…read more I rented a vehicle in Munich for cross-border travel and selected the cross-border option during booking. I also independently purchased a valid Austrian digital vignette for the vehicle's license plate prior to entering Austria. The vignette confirmation shows activation on 24.01.2026 at 14:22. The alleged toll event cited by SIXT occurred on 25.01.2026 at 13:44 -- well within the validity window. Weeks later, SIXT assessed a €200 substitute toll and charged it to my card. I provided the digital vignette documentation showing the correct plate and activation timestamp. SIXT's written response was that they "do not check whether the fine is legit or not and act according to the information provided by the relevant authority." In other words, there was no substantive review of compliance documentation. The toll authority invoiced SIXT as the registered owner. SIXT paid the assessment and passed the charge through without evaluating the evidence provided. For corporate travelers and travel managers, this presents a material concern: post-rental penalties appear to be processed automatically, with limited internal review, and the burden shifted entirely to the renter--even when documentation exists. If your organization has cross-border travel in Europe, understand how toll disputes are handled before selecting a rental provider. Based on this experience, I would not recommend SIXT for business travel where regulatory exposure and post-rental accountability matter.

First off, I was given a damaged car that I could not use and had to go back to the counter and request another vehicle after an international flight from the United States. Take pictures of the vehicle!! they will charge you without a doubt for damage they charged previous renters for! Second, and here is the meat of the extended issue, we turned in the car very early the representative said we were good leave the keys in the front seat cool right?? Nope 3 hours later while were at the gate I get an email about damage $510 worth, that we are responsible for. I am like yeah right! I got pictures to prove it was not us... It took about three weeks to get it resolved so I thought. In October I get a letter in German stating that damage is more than expected and we want more money!! Hold the phone you already said I am good! I dont care that the damage is more than you thought!! I didnt do it!! They charge my card an additional $760 right before Christmas. I am an hourly worker and my money is budgeted, I cant afford damage I have already been cleared of. I come to find out this is a scam by rental agencies in foreign countries by rental agencies taking advantage of tourists and business travelers. Not only do I want my money back I want fraud investigations to be conducted! This is poor business practice and company negligence for not reeling in this activity!

However, everything went very smoothly from checkout to drop off. No issues what so ever and my credit card was charged appropriately without any errors. We reserved online, filled up our own gas, and didn't take any additional coverage, so the price was reasonable. We drove from Munich to Fussen and had the car for 3 days... only used half a tank. I only stalled out a couple times too which is great. Do your due diligence and you'll be fine. Driving along the countryside in Germany will forever be one of my favorite memories.

The vignette confirmation shows activation on 24.01.2026 at 14:22. The alleged toll event cited by SIXT occurred on 25.01.2026 at 13:44 -- clearly within the active validity period.

When I submitted the documentation, their written response was that they "do not check whether the fine is legit or not and act according to the information provided by the relevant authority." Let that sink in: you can follow the rules, pay for the required toll coverage, provide clear documentation -- and the company will not even evaluate whether the charge is legitimate before passing it through to you. As a foreign traveler in a regulatory system you're not native to, you reasonably expect the rental company -- as the registered owner of the vehicle -- to review documentation and assist when something appears incorrect. Instead, the burden was pushed entirely back onto me. If you're renting for tourism and crossing borders, be aware: post-rental penalties may be processed automatically, and documentation may not be meaningfully reviewed. Based on this experience, I would not recommend SIXT for cross-border travel in Europe. Transparency matters. Compliance should matter. Customer advocacy should matter.
