I rented a vehicle in Munich, selected cross-border authorization, and independently purchased a valid Austrian digital vignette before 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 -- clearly within the active validity period. Despite complying with the regulations and providing timestamped proof showing the vehicle was covered, SIXT charged me €200 for a substitute toll weeks later. 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.
