Struggling where to start to put as accurate of an experience as I could. .... Yesterday was really a hectic day for me. Packing for my trip, filling up the car with gas, return it, get in line to get a receipt, get my luggage, get on the shuttle to the airport and deal with the check-in process and security checks to board my plane. All of that had to be done in one and a half hour. Well, things don't always work in your favor, Yesterday was one of those times, the gas pump wasn't working and I had to go inside the gas station to pay, the freeway was abnormally busy, with either construction going on or a collision, yes, both LOL. I missed my exit twice actually trying to find the car rental location ... , things were just against me left and right and I was super stressed and worried I would miss my flight. I arrived finally at the car rental location while many things were going through my head and I wasn't able to hide my stress until I saw a genuine smile on someone's face saluting me and preparing to check my car in at Sixt. It was not a fake smile, not just putting on a smile for customers, let me just tell you this, her smile was genuine enough to comfort me in no time. Her name was Kima and her job was to check the car in, mileage, gas level, any damage, take the car key and direct me to the office to get my receipt. ...... She just didn't do any of that. I didn't really need to explain my situation and how much in a hurry I was, she intelligently got it all from my body language and my facial expressions the minute I rolled down my window and started talking to her.. she immediately, and with the same smile, comforted me and said "Not to worry, I will take care of you" She left my luggage in the car, asked me to skip the wait for the shuttle and drove me with my luggage herself to the airport to catch my flight which to her it was set and determined that it was priority number one. I am a gold member and they have all my information, credit card, driver's license etc, so I believe she analyzed the situation quickly and figured it out ..... "this can wait" or " worst case scenario, we will just charge bill him for any overages" or " it is not the end of the world" ..... I will never know what she thought that minute or how it was processed that fast in her head but she quickly and professionally took the initiative by deciding to put the customer situation first. I believe she made an excellent decision from a customer service point of view which in my experience I would say more than just normal customer service. Others may just stick to their job scope or probably may just give me the courtesy by calling the shuttle for me or maybe assist with the luggage. I wasn't expecting anything more. We arrived at the domestic terminal, I got out of the car and asked a security guy about the airlines terminal, it turned out that my flight leaves from the International terminal ... I look at her behind me and she immediately said "International terminal it is" .... she was waiting in the car to make sure I was at the right terminal and right door. Amazing ... What Kima did was beyond all expectations. The amazing part was that she quickly decided to jump in and help beyond her normal job scope. A simple thank you is not enough as a response to what she did. What she did calls for recognition and appreciation. This is the spirit we need in our businesses these days, that is why I am taking a few minutes of my time to write this review like she did take a few minutes of her time to help me. You never call the phone company and thank them for having a dial tone every day, you only call when there is a problem ..... sadly enough we got used to this habit. Today I am changing this habit and putting a good word for Kima, the Sixt girl who helped me at the South San Francisco location yesterday. I hope her bosses and coworkers read it and recognize her as well. Right on Kima .... even though I missed my flight and they put me on a later one .... but it was due to airport regulations and time needed for checked luggage etc. Hands down ... You definitely did an awesome job .. keep that smile ..... Sixt needs it for other customers. THANK YOU Mohammad Soliman read more

RENTAL HAD BALD TIRES - SIXT CHARGING ME $1,700 FOR FLAT TIRE & TOW!!! In August 2025, I booked a car rental of a "BMW or similar" with my Capitol One Venture Travel card. At the time of getting the vehicle, I was provided with an ELECTRIC vehicle, despite me telling the rental agent that I would be using the car to travel to Mendocino County. If you know northern California, you know how inhospitable and how few and far between electric charging stations are, and fast chargers at that. On the last day of my trip, my minor daughter and I got a flat tire and were stranded in the middle of nowhere between the Pacific ocean and Healdsburg, CA in a no-cell service dead zone with virtually no cars driving through. I had to walk half a mile up a hill to find cell service enough to contact Sixt and inform them of what had happened. We were disconnected 4 times due to lack of cell service wherein I had to contact the 1-800 number again and again to talk through the situation with a new person each time. Sixt told me they would dispatch a tow truck and that I would have to wait by the vehicle until it arrived, which would take 3-5 hours. I refused to wait by the vehicle-- it was dangerous for my child and I. There was no spare tire in the vehicle and the tire-kit was insufficient to fix the huge gash in it. I was only able to provide coordinates, the only way to provide the location of where we were stranded. Upon further inspection of the flat tire, I realized that ALL the vehicle's tires were worn down to the threads! Sixt had provided me with an unsafe vehicle with defective threadbare tires. (SEE PHOTOS provided here). There's NO chance that I caused these tires to become worn down to the threads in the 3 days that I rented this vehicle! (I always inspect my rental cars before I drive them off the lot, but I've only ever looked for surface damage, and never thought to inspect the wear on the tires, nor could I have seen how threadbare they were from the INSIDE of the tire wheel!) Luckily, a truck came by with a nice family offering us a ride an hour away to Healdsburg, CA so my daughter and I could eat a meal and use a restroom. Once in Healdsburg, I had to reschedule my flight home and book a shuttle back to SFO airport, which incurred additional and unnecessary expense to my trip. Once at SFO, I personally returned the car keys to the Sixt rental counter and explained again what had occurred. At this time, I asked for a full refund for the car rental due to the fault and liability for the defective car I received, which resulted in the flat tire and tow. The agent typed my report into his computer and advised I call a 1-800 number to follow up a few days later. Some days later, after I returned home, I received an email which allowed me to make a "damage claim," but it was only done through a link that did not allow me to upload the video I'd made of the threadbare tires or add any additional notes of explanation. After I'd submitted the Damage Claim I received and email stating that I owed over $1,700 for the tow of the vehicle back to the SFO car rental location. I refuse to pay this, and I expect a full refund of my car rental and additional expenses. I will contact an attorney, if necessary, and I am relating my story here in hopes that this can be resolved in a fair and reasonable way. read more

This review is not specifically for this location but for general phone customer service. Sixt car rental is a business that is not customer centered. Once they have your money, it will be very difficult for you to reach a customer rep on the phone. Once you get through, there's no guaranteed that your problem will get solved in a timely manner because the "system just won't let them." From my experience, if a company cares about their customers, they will find a way to fix the problem for you without hesitation and all the red tapes. I highly recommend you rent someplace else who is more supportive of customers , especially if an unforeseen circumstance comes up. ------------full story--------------- I originally paid upfront to rent a car for 8 days. Due to health circumstances, we had to postpone this trip. Sixt fines you a HUGE penalty for canceling so I called a customer rep to get some options on what to do because I did not want to lose $400 for canceling (total was $1200). After playing chase with their automated customer service number for ONE HOUR, I finally got someone on the phone. This lady told us we can get a voucher for the amount we paid towards the next booking. Sounds good right? So we booked another car. When we went to pick it up, the worker told us that we should already have applied the voucher when we reserved the car. Payment changes can't be made when you pick up your car so we had to call customer rep again. When we got someone on the phone, they said Sixt does not do vouchers when it's over a specific amount. We spent a lot of time going back and forth and they kept transferring us to new customer reps. All we wanted was to apply credit from the old reservation to this new one. BUT company system does not allow that. So we had to cancel the old reservation, paid the $400 fine which was then applied to our new reservation. All of this took TWO HOURS. This has been the worst car rental experience I've ever faced and would not want this to happen to anyone else, especially if an unforeseen circumstance comes up. read more

Buyer beware. My experience with SIXT has raised serious concerns about what appear to be aggressive and potentially deceptive billing practices. Before renting, I encourage anyone considering SIXT to spend time reading BBB complaints, Reddit discussions, consumer forums, and news reports regarding damage claims and post-rental billing disputes. Many customers describe a similar pattern: damage claims appearing after vehicle return, disputes over pre-existing damage, difficulties obtaining clear evidence, and frustration with the claims process. I am currently in the middle of my own dispute and have submitted documentation, photos, videos, and other evidence. At this stage, I am still waiting for SIXT's response, so I will reserve final judgment until the process is complete. What I can say is that I have spent a considerable amount of time researching the company since receiving notice of my claim, and I was surprised by the volume of similar complaints posted online. BBB complaints, consumer forums, and travel discussions contain numerous reports from customers who believe they were charged for damage they did not cause or who felt the burden of proof was unfairly shifted onto them. There have even been consumer lawsuits and settlements involving allegations related to damage billing and collection practices. While SIXT has denied wrongdoing in those matters, the existence of such litigation should give consumers reason to carefully document every inch of a vehicle before and after rental. For now, I'm keeping the details of my case private and won't be showing all my cards just yet. I remain hopeful that SIXT will review the evidence fairly and reach a reasonable resolution. If they do, I will gladly update this review. If not, it may be time for affected customers to explore their legal options together. Based on the number of similar complaints online, I would not be surprised if additional class-action litigation is pursued in the future. Until my case is resolved, I cannot recommend renting from SIXT. read more

The Worst Rental Car Experience of My Life This was by far the worst rental car experience I have ever had. From the moment I picked up the car, nothing was clear or transparent. They hit me with hidden fees that were never mentioned during booking or explained at the counter. What should have been a straightforward rental turned into a nightmare of extra charges, excuses, and complete lack of accountability. To make matters worse, I was later charged for supposed "fines" that I never received, never saw, and for which the company provided no documentation whatsoever. They simply charged my card without warning, without proof, and without giving me any chance to dispute or even understand what these fines were. This is not only dishonest, it feels like outright theft. When I tried to get answers, customer service was useless -- rude, unhelpful, and quick to dismiss my concerns. Every time I asked for proof or clarification, I was met with silence or vague responses. A professional company should be able to provide paperwork or at least explain why a customer is being charged. Instead, they act as if they can just take money from your account whenever they want, no questions asked. I rent cars frequently for business and travel, and I have never dealt with such shady, unethical behavior. This company is predatory, deceptive, and completely untrustworthy. If you value your time, money, and sanity, avoid them at all costs. There are plenty of other rental companies out there -- don't make the same mistake I did. read more

Yes, SIXT is yet another 5-minute shuttle away from the onsite SFO car rental hub where most other companies are located. (to get to them all takes 10-15 minutes on the AirTrain). And yet somehow this fairly tiny inconvenience of additional hop-on-hop-off itches irrationally while you pass all the rentals stands in order to get to Sixt. :) But it was completely worth it for us -- we got a great upgrade! Although it was only one category up, the car was a small modern Mercedes sedan instead of a Hyundai Sonata. Magic was still awaiting though! After 10 days or so, we have realized that we actually need a car for more days, and Sixt call center suggested that although we could request an extension, we might be better off returning the car and re-booking for the longer period because there are better fares for longer than 21 (or 22?) days rentals. So, excited to possibly get an even better deal for my category, but hoping to remain on the same (upgraded) car, we drove to Sixt. Only to discover yet another upgrade! Now it was a Mercedes SUV instead of a sedan. What a treat! Despite we are not using the car much given the COVID restrictions, we enjoy it even so much more during those 10 minutes of driving to the essential places. Thank you, guy! PS no, we did not get the better fare though, because after all, our rental was not long enough to qualify, but we are completely happy. read more

Sixt rent a car is not even deserving of a 1 rating. It is by far the worst rental car company that I have had the displeasure of attempting to rent with and Priceline should be ashamed to include them with their services!!! Twice we booked a reservation with the company and we weren't able to pick up a vehicle. The first rental was a no vehicle available and then a cancellation. On the second no show reservation, they tried to make us pay an additional $300 for an upgrade and a deposit of $1000 to get a vehicle. We didn't agree to pay the difference, which according to Priceline, their agreement is a FREE upgrade, if the rental vehicle we requested is not available. They said they would cancel the reservation. It took two weeks for Priceline to return the money that we paid them for the Sixt car rental even when we never received a vehicle. Both companies hid behind their policy blaming the other. I called Priceline repeatedly who stated the only way that they could do the return was to wait for an email response from Sixt. That email response took two weeks, that is absurd. I even wrote the company myself and it took them 7 days to respond to my email. I am fair warning you, Sixt is truly a substandard rental company regardless of their great express deal prices!!! read more
