For my trip to Belgium, I booked an electric Mini Cooper through Sixt’s website well in advance for the dates April 25 to May 2. When I arrived at the Sixt desk at Brussels Airport, I asked the staff—specifically a woman at the counter—about the range of the electric vehicle to avoid any issues. She told me it had only 90 km of range, even though the website clearly listed 300 km.
Concerned about usability, I decided to upgrade to a BMW 1 Series petrol vehicle, for which I paid the price difference. She also recommended basic insurance, which I agreed to, trusting her professionalism and signing the contract without examining every detail.
Later, I noticed that an additional €200–€250 was charged to my card, on top of the vehicle upgrade and insurance—and excluding the €300 deposit for traffic fines or damages. I immediately contacted the Turkish-speaking Sixt staff I had dealt with, but I’ve yet to receive a response.
What’s most frustrating is that a friend who traveled with me rented from a different provider based in Turkey and encountered no hidden charges or surprise fees.
I demand a full breakdown of the charges, an immediate refund of any unjustified extra amounts, and clear accountability from Sixt. A trusted international company should not rely on vague explanations or undisclosed charges. If I don’t receive a resolution soon, I will escalate this complaint through formal consumer channels.
