I would have given zero stars if that was an option. My family and I were in Spain for 6 days. I rented a vehicle with Europcar and bought the Premium insurance and the roadside assistance service. Within hours of being on the road, the AdBlue light started flashing, and I looked in the manual to find out what AdBlue was and it just said to add AdBlue. So I called the roadside service number. I was told that the car had not been serviced so I had a choice of returning it to the airport which was over 1.5 hours away or to stop at a station and fill it ourselves, save the receipt and get reimbursed upon returning the car. After 22 hours of flight transfers and travel, we were not going to spend 3 hours (going back and forth), so we stopped at a station. Turns out the AdBlue tank was at capacity. I called to inform Europcar that we had plenty of AdBlue but that the symbol was still flashing. I was told the car was fine. We proceeded on, but then a red and white message appeared and a voice started saying something and there were sounds coming at us. We were all startled by the commotion the car was making. It said, "Top up AdBlue. Impossible to start." I called Europcar again & explained what we were experiencing and was told I if I already had AdBlue, continue on. 15 loud minutes later we reached our destination. The next day the car wouldn't start. I called Europcar assistance AGAIN and was told that our reception was bad though I could here the rep clearly and she said to call back later and just hung up the call. I called again and she answered the line and said the car should work, and that our connections was bad and hung up. Next day the car still didn't work. This time someone else answered and said they'd send a tow truck to get the rental. I asked about a replacement car and was told I'd have to go back to the coast (over 1.5 hrs away) but that the office was closed on Sundays, so I'd have to wait till Monday (the next day). On Monday, tow truck came and the driver said the car had a big problem; he needed help. Europcar wouldn't provide a taxi for us to get a replacement car until their car was towed away. When it gone on the flatbed, I called and it took over an hour for taxi to arrive. We got to the airport, were given another car, but it made strange engine noises when we reversed out of parking space, so we asked for another car. Next car, was dirty inside and out, but our children were back at rental lodging for over 2 hours and we had a 1.5 hour drive to get back to them, plus the rental car counter was at the opposite end of the airport and we'd have to walk the path again, so we figured we'd wash the car ourselves. Stopped at a gas station and the dirt was sticky gross. Barely got any off. We had use of a dirty operable car for less than 3 days during our 6-day vacation in Spain. We asked for a refund that reflected the vacation time we lost and the time without an operable vehicle. Though Europcar did agree to a refund (probably because we got Capital One, our insurance company involved), the amount they returned was minimal. Didn't reflect what we should have received. STAY AWAY from EUROPCAR. We travel a lot, especially this past year and those pre-Covid years. This was my first and very last time I will ever use Europcar. I recently read other people's reviews and I'm not surprised at how horrible their experiences have been. I wish I had read the reviews before booking with this unreliable, cheat of a company.
