We booked a Volvo XC60 but were given a BMW X3 ES RK. They said it was the same, and because our English isn't great, we didn’t ask if there were extra charges. Later, we found out there was an extra charge of 600 euros for our 59-day rental. Also, after driving 2,000 km, the screen showed a warning to replace the engine oil. I feel like they gave us a problematic car. This is the first time we’ve encountered this kind of situation, and it's really frustrating. We called three times but no one answered. When we emailed, they told us to visit the nearest Hertz branch to have the car replaced. At that time, we were in Norway, but the Hertz branch in Norway told us that since the car was rented in France, the issue had to be resolved with the French office. In the end, we just kept driving that car until this trip was over.
