This is the main 'Sixt Car Rental customer service' (Toll Free) phone number: 1*888*693*8772. It's toll-free line is open 24 hours a day, 7 days a week for car rental reservations, booking changes, cancellations, baggage inquiries, refund requests, and other travel-related needs. Absolute worst rental experience we've ever had was with this particular Sixt. Specifically the manager Tori was the rudest most unprofessional person I've ever worded with. She left dozens of ppl stranded with no rentals after giving away all the reversed rentals. Causing dozens of people to be stranded at the Sixt airport at 1am. Her entire staff was disrespectful to every single customer. She made my children cry and left elderly handicapped people and small children stranded in an airport and told them she didn't care. Spoke down to them and belittled them. I hope she is never allowed to treat people this way again and something is done about her and her employees callus attitude. after reading more reviews it seems this is an on going issue and Sixt has allowed this disgusting behavior from their employees. Stop all the extra fees and renting people a car but when they get to the rental station up sale them and charge more money. Rental cars in Sixt is a scam! Horrible customer service. Had a car confirmed and then they said it wasn't available when I arrived but they conveniently had another available for just $100 more. They have a 1 rating for a reason. Employees could care less here. read more

Sixt Rent A Car - Car Rental Near Me - Houston, Texas

I rented from SIXT at Houston Hobby Airport in April 2026. I originally booked a Toyota RAV4/intermediate off-road vehicle through Expedia, but at pickup I was first assigned a Toyota Tacoma and then changed to a Toyota Camry. The vehicle class was downgraded, but I did not receive any price adjustment or refund for the downgrade. After returning the car, I later received a damage claim. I disputed it and provided my rental details and evidence. SIXT eventually reviewed the case and closed it without any further claim against me, which I appreciate. However, the rental experience was stressful because of the vehicle change, no refund for the downgrade, and the later damage dispute. I recommend customers take full photos and videos at pickup and return, and make sure any vehicle change or price adjustment is documented in writing. Be careful with SIXT Rent a Car read more

I had a great experience with SIXT at Houston IAH International Airport during my pick-up on March 19, 2026. Even though there were long lines and a busy crowd, the process was handled efficiently and professionally. A special shoutout to Mr. Smith, who truly stood out. He managed the high volume of customers with patience and professionalism, keeping things moving while still making sure each person was taken care of. He accommodated us smoothly throughout the process, which made a big difference. During my inspection, I did notice a small dent on the vehicle, but I'll be sure to report it upon return. Based on my experience, I'm confident Mr. Smith will be a great help in resolving it. Customer service like this goes a long way, especially in a hectic airport environment. Thanks to Mr. Smith, what could have been a stressful experience turned into a positive one. read more

Sixt Rent A Car - BMW rental from Sixt - Car Rental Near Me - Houston, Texas

I was planning a trip to see my sister before she died! Unfortunately I didn't get to say goodbye as she passed before I could arrive. So I cancelled my car reservation. I received the notice that my cancellation was acknowledged and a refund would be sent. That's the RUB! The total cost of the rental was to be $121.02 The refund will be far less than charged as the CANCELLATION FEE is $88.02! Needless to say, I am not a happy customer. I will NOT ever contract with this company again - - - and will certainly tell all my friends and acquaintances of this experience. read more

Sixt Rent A Car - Car Rental Near Me - Houston, Texas

I've rented a few times now from this location. The draw for me is their luxury car selection and price point. If I can rent a luxury car for about the same price as non-luxury which Sixt usually offers, I'm in. For this trip I got an X5 with only 2k miles. The miles are usually higher but seems like all rental car companies have higher mile vehicles lately. I've rented mostly BMWs (5 and 3 series). Pick up has always been seamless with minimal to no wait. Alem is amazing and has always taken good care of us with exceptional service. Would recommend and will continue to return. read more

Rented a car from Sixt at the IAH location and it went very smoothly. Our flight was delayed and we arrived late so it was very helpful that they were open until midnight. Issobella who took care of us at the counter was very friendly and they had the car that we had reserved. The return also went seamlessly. Would not hesitate to rent from them again. read more

Picking up car at WA DC airport was harrassment: trying to get us to pay to upgrade, add insurance etc. Implying our reserved car wasn't available, but it was. Had to say "No" 100 times and she still continued. Told her we were tired and hungry just off of a long flight, just give us what we reserved so we can go. Relentless. Finally had to get rude to be able to end transaction. They must be paid on commission for add ons bc it was ridiculous. read more

I had such a positive experience renting from Sixt in Houston. I was a bit tired from travelling, but Emmanuel made everything effortless. He greeted me with a smile, explained all the options in a calm, patient way and made sure I was comfortable with the vehicle before I left. You can tell he genuinely cares about his customers. Because of Emmanuel, Sixt will be my first choice whenever I'm in Houston. read more

There is a reason they have less than two stars. They are like a black widow spider, trying to snare unsuspecting people into their web. I do not recommend this company and their bad policies. I reserved a vehicle, made a mistake and canceled in just a few minutes. They charged me $100 anyway even though the reservation was two weeks away. I then had to file an AG complaint and a dispute with the card. In 55 years, I have never been treated by a rental car facility this way over a booking. When I went to rebook, I selected a different company. read more

Sixt Rent A Car - They are a sham company with bad policies. This booking was canceled minutes after making it. - Car Rental Near Me - Houston, Texas

Customer Service horrible. I prepaid my reservation at one price and upon getting ready to head to the airport for pickup I noticed the price increased by $50. I called customer service and they would not remove the additional charge and the only way I could be refunded without a charge was to cancel the reservation which left me without a vehicle. The prices had increased on all of the vehicles by this time. I was told that if I was to pick up the vehicle that I would be charged the $50 increase. Then proceeded to say there wasn't anymore cars available to create a new reservation. My sixth experience was a nightmare read more

Most crapped out car I have ever rented. Apart from numerous dings, while driving from the airport I noticed that neither side mirror was working properly - the L would not move down all the way, limiting road visibility, while the R didn't move in any direction, making driving dangerous. On arrival at my hotel, I immediately contacted Sixt to let them know of these issues and requested a replacement car. I was told that my request would be marked urgent and someone would get back to me very soon. About EIGHTEEN HOURS later (so much for urgency) I was contacted by an agent from Sixt, who informed me that I would be able to pick up a replacement car the FOLLOWING DAY at the airport if I wished. Due to the distance from the airport and time involved, I chose not to change the car but rather drove it rarely and used Ubers instead. I also noted that the tire pressures were way off (L front 46, R front 34, L rear 35, R rear 47). Upon returning the car and informing the attendant of the mirror issues and problematic tire pressures, she simply took no notice and wrote nothing down, leading me to suspect that the next customer would receive the vehicle in the same dangerous state as I did. The next thing I received was a notification that I was responsible for a damaged L side mirror! Eventually I was able to have that issue closed without any charge to me. First and last time renting from Sixt. I should have read the reviews before renting from them. Seems to be a pattern of charging for so-called "damage". read more

TD;LR: Long overdue, but sharing my story of misconduct from Sixt Downtown Houston. Apparent fraud situation occuring. I reserved a car from Sixt Downtown Houston for Valentine's Day weekend. Before this, I had reserved at this location multiple times, and despite varying experiences with the staff, my reservations have been fairly seamless. Never had an accident with any cars that I rented and returned it in proper condition. When I arrived, I was asked if I wanted to car that I had two cars to choose from (a Camry or a Volkswagen Jetta IL-EJ51603). I was in a rush so I chose the Volkswagen. The agent that helped me took 10 minutes to take the elevator to whatever floor and finally brought the car down to me to view. When the agent brought it to me, she said that she had no idea that the mirror was broken and the other damages to the car. There was a plethora of damages, which included scratches and a busted side mirror that I could not adjust. This was a personal hazard and should not have even been in their roster of cars. Instead of offering to give me a new car at no charge, she said that I could pay more for a change in car or take this one. She had quickly forgotten that she had offered me another car and instead, created a situation where it was this or having to wait another 10 minutes for her to get another car, which I would have to pay more for. I reluctantly took this one because I was in a rush. My major mistake was not taking photos of the car before I left. I drove the car and had no accidents, and returned it before it was due. However, the same week I received a message saying that I was being charged for two scratches on the car tires. They were so small, I had to squint to see what they were referring to. I immediately petitioned to have a deeper examination into the situation from the main offices because whoever cause the car to be in that situation caused the scratches that I was being accused of doing. No one ever contact me and sent a lifeless email saying that I was responsible for the damages. Since I didn't take pictures, they said I didn't have anyway to prove my claims. I then reached out to Woo Kim, the branch manager, to get the reports on the car since there was so much damage to the car. He picked up and lied and said that he would help and get more information. He even offered to refund me some money because he knew that car was unfit to be driven. However, he never got back to me. I emailed him, called him - he never replied. They immediately sent the damages to subrogation and are charging a crazy amount to fix two small scratches. For months, I had been reaching out for information about the process and transparency, and have been completely ignored. It's apparent that SIXT's model is to attach a customer with a damage they didn't cause so they can recoup some money on cars that have are already unfit to be occupied. I am sure that I am not the only person that has had a damage fee applied to them for this car. This needs to be investigated. I am horribly disgusted by the malicious bureaucracy and indifference that SIXT has shown me and probably has shown countless others. Clearly, the Houston Downtown branch needs to be closed because of the lack of transparency and the apparent fraud that has been committed. The fact that they gave a sub-optimal car to customers (I could have easily got in an accident), assigning unfair charges to customers because they can, and the general indifference that they have shown customers, are all reason to close down this branch. However, it is the main offices indifference and lack of transparency with their customers that showcase that SIXT overall is a company to avoid if you are renting a car. Do better, SIXT. I hope this review helps someone know to avoid the Downtown Houston SIXT and SIXT in general because it will only cause you an unnecessary amount of personal harm. It's not worth it and there are more reliable companies out there. read more

This is my 3 time renting with sixt, twice in Texas and once in Florida. The customer service was amazing at all locations. I'm able to rent luxury SUVs for the price of a compact sedans. My last experience with Kareem in San Antonio was great. He explained everything thoroughly, cracked a few jokes, and sent me on my way in less than 10min. I am a Hertz 5 star member and I'll happily bypass them for sixt's prices and awesome customer service. read more

You need a new system that checks motor vehicle records. You informed my husband that his license has been suspended since 2014 which is impossible. Then I couldn't put the car in my name because you can't rent to any person in the household. That just sounds like complete bs. read more

I reserved a car for three days, but when my flight was canceled by airport, I called to cancel the reservation. They kept my total fare amount. There excuse was I had to cancel before 72hr and I was a no show! Of course I was a no show the airport canceled the flight idiot. And of course I couldn't cancel my reservation cause the flight was canceled within 72hr cause the airport canceled the flight on the same day idiot. I would never recommend this care rental company, they have the worst customer service!!!!! read more

I booked and prepaid for a 7-seater SUV for December 24, 2025 to December 29, 2025 to pickup at the SIXT in IAH airport. I walked to the rental company to get our prepaid rental and we were told they were out of cars and did not have our PREPAID rental car. The only car that was available to seat 7 passengers was a minivan. I booked the car far in advance and prepaid to make sure that when I got there I had the car I wanted. Mind you we were there for our daughter's wedding and it was Christmas Eve and we were tired. I am still trying to get my money back from them and Expedia has reached out to them 3 times and they have not responded. I have a case that is still open. I should have learned from our trip in October 2025 when they also did not have our car available. However, I thought for sure they would have our prepaid car ready. We had to go to the other car dealers and luckily Alamo came through with an 8 passenger SUV. Unfortunately, I had to pay twice as much as my prepaid amount because we were stuck. Do not think if you prepaid you have a car from Sixt. I am no longer going to rent from them. Now I am waiting for them to contact Expedia so I may get my money back. Shame on them. read more

The absolute worst experience ever! I should've known from my first interaction with Jeremy that Sixt was pure garbage. Jeremy (Check In associate) had a nonchalant, condescending attitude. I repeatedly declined an upgrade; yet he continued to push it which tells me that there's another motive for those upgrades. I asked about the deposit. He didn't care to explain its purpose. After check in: I picked up my keys from upstairs. The associate was pleasant; however the FIRST car smelled of marijuana. I requested a second car. The SECOND car smelled of marijuana too. What's the probability of two cars smelling like marijuana? I returned the car and mistakenly left my bags in the trunk. When I returned, the associate told me that the cars are NOT outsourced for cleaning and are cleaned by non-English speaking SIXT employees downstairs. So if the car never left SIXT's possession, why haven't my items (portable car battery with cables, Bluetooth, earrings) been returned to lost and found area? SIXT clearly knew who owned the items since the company had my ID, address and other verifiable information. Just because someone leaves something in a car doesn't give the employees permission to keep it. Yeah, you have a sign that says you're not responsible for items left. But you are responsible for hiring ethical people and creating a culture of accountability. Never again! Keep your weed-smelling cars and unethical, condescending employees. read more

Charging me $566 for a minor scrape on rim of vehicle. Normal wear and tear and I don't believe it was actually just can't prove it. Plus there was no corresponding scrape on the tire from picture they sent me. Prior to renting I looked the car over and never noticed this. Seems suspicious and petty. read more

They overcharged me. I had already paid for rental for the entire trip from Expedia and even got protection from Expedia. I know they mentioned charging for Ezpass, which was 15$ per day, so it should only be 135 extra, but I was charged at the end of the rental for 300$ (which was for nine days). They are adding some additional fees for nothing without any real explanation. It's a good thing I am only going to Houston for a one-time event. I would never rent from Sixt again. The rental car had 19k miles, and the maintenance light was on the entire time. No one takes care of the vehicles over there. I strongly advise you to refrain from renting a car from Sixt. I should have seen all the negative reviews. read more

I rented a car at the San Diego airport. there was no damage to the car when I locked it up. 2 days after I returned car I received an invoice for $675 for a 10cm scratch on the bumper. the lady that walked the car with me when I dropped it did not note any damage. unethical disgusting company. I've been using a is for years and thought I'd try sixt because their car selections are so good. Disgusting company. Do rent with them. read more

Sixt Rent A Car - Bogus claim. This is scratch they said I made. Lies lies lies. Terrible unethical company. - Car Rental Near Me - Houston, Texas

DO NOT USE THIS CAR RENTAL!! I went online to look at vehicles and was considering renting a Chevy Tahoe. I put in my cc info but didn't complete the transaction. The next thing I know I'm getting a charge on my credit card from Sixt which doesn't even match the price of the vehicle I was looking at. I call to find out what it's for and they say they can't find a reservation for me. I emailed customer service 3 days ago but no one has responded, I only received a generic separate email with a reservation receipt for a compact limo. What the heck! They gave me a refund for everything but $100. I'm not sure why I'm having to pay a $100 fee when I didn't reserve in the first place. It's a fraudulent charge! Believe all the reviews you see!!! read more

Warning: Do not rent a car from SIXT. SIXT is notorious for scamming their customers. Here is how the SIXT scam works. First they rent your car which likely has some pre-existing scratches. Like a responsible customer you take pictures of the pre-existing damage. You return the car in the exact same condition as when you rented it. A month later SIXT sends you an email falsely claiming you caused the damage. You provide the pictures of the pre-existing damage, they refuse to dismiss their claim. You refuse to pay because you read all over the internet that SIXT is a scam company trying to extort their customers with concocted vehicle damages. So they sell your "debt" to a collections company who then files a negative debt report with the three major credit bureaus. A few months later you attempt to get a loan and realize that your A+ credit is now a B- at best. You have worked your whole life for A+ credit, and now one sleazy unethical company named SIXT has wrecked it. SIXT is a scam. In 2025 SIXT settled a class action lawsuit for $11 million for this scam. Stay far far away from SIXT rental car agency. read more

Reserve the car, pay in full... in advance (only noteworthy because you are now at their mercy in a way and have to take whatever BS they come up with) shortest line with the longest wait time... one agent, 6 desks... WallyWorld of rentals apparently? Wait forever to get told the car they texted me was ready wasn't even available... wait around forever.. standing... for several customers before "the manager" like the banker from deal or no deal? Says he has an X6 available (rented an X5) why wasn't that offered to begin with for your incompetence? Just sayin.. then she can't find this ghost car in the system anyway- can't offer an X7? "Too many people reserved that one today" I mean.. rent at your own risk... the reviews are right here and let's be real right now... they don't look good.. AI is about to replace all these idiots that apparently can't even scan cars into inventory correctly and I mean that with full offense intended and delivered unapologetically and with my whole heart... I've been in customer service my whole life and this is not it- oh yeah and if a real person that is intelligent and can make decisions at this company reads this... your employees or your system is inefficient and not at all working, read the other reviews this isn't a one off- taking somebody's money once isn't a sustainable long term business strategy, some of us are literate and will use our time standing here to roast your a$$.

If I could give it 0 stars I would.

That bald Man said he couldn't do anything because it was through Expedia (which I understand). so the next day I call Expedia, they say they are going to call the rental company and the rental company tells them I requested the rental!!!
