Needing an oil change on my GMC Terrain, I headed over to Billions to take advantage of their Express Lube service. No appointment necessary. Had about a 30 minute wait; this service is popular! I was in and out in less than 20 minutes for a full service oil change and tire rotation - - impressive!

The service on my vehicle was exceptional. The only issue I have is the amount of loaner vehicles that you have. I dont live in Sioux Falls and having to sit at the dealership for 3-4 hours while I wait for my vehicle to be done, isnt exactly my idea of fun. I suggest that you add more loaner vehicles to your fleet. I also own a Ford and any time I take it to Sioux Falls Ford they have a loaner for me to run errands in.

Had great service!! We had traveled close to 4,000 miles and my hubby was beginning to get concerned about our oil needing to be changed. So we pulled in and thank God on Sat. they were open and it was first come first serve. We were in and out within an hour and back on the road!! Thanks guys!! You are the BEST!!

Oil change and service completed in time estimated. Tires rotated and filled with equal air all the way around. Friendly staff.

I had a great experience with the work I needed done on my truck! Assuming that it resolved the leak, I am very pleased with their process, facilities, and personnel. It was a streamlined experience from intake to the courtesy shuttle. The waiting area was very nice and comfortable. I was communicated to regularly and the work was done quickly. The shop was super clean and professional. I wont hesitate to bring my truck here again and if I need to purchase a new car or truck, I would definitely look to Billion as the service department was top notch.

The person that checked me in had no customer service skills at all and could use some customer service training. I am not sure because the line for service was long, however he needs to learn how to greet customers. The business could help themselves by having someone whose job is to check in customers. I am not sure I will ever bring my vehicle to them for any service in the future.

Brian, and Jason are top notch sales team and are devoted to putting people like myself into vehicles that they want and customers come first

While Dave treated us very well, we still have an unresolved issue with our car. We have spent a good amount of money and hope it can be fixed soon. The loaner was very much appreciated.

Jason Donavon and Red have been servicing our vehicle needs for many years; and they are always professional in all they do. Great guys.

Salesman (Tom) was very knowledgeable...not pushy...very considerate, listened to and answered all my questions

Although the fist young gentleman I spoke to in the Quick Lube service area was a bit unfriendly, he became light hearted, helpful and accommodating quite quickly

Car came out with more problems than it went in with. Billion on 12th is the place to go and trust worthy. Only went here because no openings at billion on 12th when I needed to get my car in.

Adir Morales is the best salesman we have ever had ,and we have been buying trucks for 40 years in the area. We bought 2 trucks a week apart and I have told many of my friends and family to go see him. Thank You !! for the awesome experience!!

Initial evaluation went ok. Your people discovered 4 things wrong. But then it needed to be..Blessed by the extended warranty guy. So I brought the vehicle back in at 8am the next day. It was evaluated Tuesday and you had the vehicle all day. No word Wednesday, from warranty guy, by Thursday you heard back and they approved 2/4 items and not the one that I brought it in for to begin. I authorized the work on the cruise control (not covered) brought it in and waited 3.5 hours for the work. Come to discover the next day that the cruise control still doesnt function,Needless to say I am disappointed with the whole experience especially the extended warranty people. Make one wonder if I should buy my next vehicle from GMC

Rep was very thoughtful, polite, and respectful of my input. Came up with good suggestions without overselling them. An extra thing that I hadnt noticed but was covered under warranty also got resolved. He also helped with the paperwork needed to get a rebate on the set of tires I purchased.

Excellent t service. Fast and very friendly.

Danny was helpful and did a great job explaining what was going on with my son’s SUV and in explaining our options for repair. We will certainly be back!

They were amazing! So happy I get my crossover care there.

Jesse McGraw was absolutely one of the best salesmen I’ve ever dealt with. We traveled almost 600 miles for the 2021 GMC Yukon Denali because they had an exact match to the one I wanted and he took care of everything over the phone and by email so when we got there all we had to do was sign paperwork. He was the only salesman I’ve ever dealt with that promptly returned calls or got answers to any questions I asked. Would highly recommend him to anyone!!

My experience at Billion could not have been better. This was my first time buying from Billion and I will definitely shop at Billion in the future due to this positive experience. My salesman, Jesse, did a fantastic job informing me about the many features of my new vehicle to include the details of the GMC app. On the finance side, Ehab, was extremely knowledgeable and helpful with the different options to purchase my new pickup. Thank you for making my purchase so smooth!!

The people that do the oil change could of been nicer and not so rude and at billion auto chevy they gave a check list of everything that did like how my fluids and tire pressure and filters was good or needed attention gmc just did oil change without doing a check list I didnt know I had to ask for them to do that too am? I am new to the area and never been to where you can get a quick oil change I asked what I need to do and they were rude to explain what to do and how it goes the billion auto chevy employees were nicer than the gmc employees

I brought my 2019 Envision in because the thermometer was either very slow responding and/or not working to temperature changes. Danny Dunagan had updated programming on ECM after finding no codes showing a problem with the thermometer. I believe the update solved the problem as the thermometer seems to be working fine now. Please share my thanks to Danny. Thanks again, Thadd Heberling

Adir Morales is amazing! My experience at Hyundai was not good and I am so glad I contacted him! He got me a GREAT deal. I am so happy with my new car.

This was my first time buying a new truck and over the phone, and email. But Jesse McGraw made it quick and easy. When we picked up the truck we were passing thru going to a wedding so we had our two young kids, he was quick, understanding, and even helpful with the kids when they became a little antsy. All around a good experience will return.

Don’t waste your time for an oil change unless you’re first in line. Ridiculously slow. I left and got mine done at a quick change place...pretty sure I’d still be in line!

If I could give this place zero stars, I would. THIS IS YOUR WARNING, DO NOT COME HERE. They will screw you over in a heartbeat. The guy sold me a truck, said nothing was wrong with it. Said it was perfect and ran great. Really? Then why did I have to have the oil leak fixed, the ignition switch replaced, the seats sewn up, and the battery replaced twice...after the second day of having this truck, that “supposedly” runs great and is perfect? Exactly. The radio doesn’t work either, so I have to fix that myself, and the Fender Flares flew off driving the truck down the interstate due to them being put on poorly. They said they’d pay for all the damages done, but after they said that, they stopped returning emails and calls. Highly thinking about suing for deceptive advertising.

Very nice. They listen to what you want, help you with your needs and do what they can for you. If you find anything wrong with a vehicle they fix it for you (scratches ect...)

I shouldn’t have gone on a Saturday however the thing that bothered me was after I waited in line for 2.5 hrs to get my oil changed and tires rotated I watched as my truck sat parked next to the building for nearly 15 minutes before someone finally came and said it was done after I had to ask if it was complete

I knew the vehicle I wanted and the sale and paperwork was handled in the most efficient manner,salesman was knowledgible of truck and gave me the information I needed

We are traveling with our fifth wheel and our battery died on the GMC Sierra. Although we could jump it, no dash controls or gauges.Drove to Dillion service bay and they looked into Within 1/2 hour. Panic nope? Ran some tests, installed new battery, fixed a loose cable and back on othe road in under 2 hours! Who does this kind of friendly, fair, quick, no appoint service anymore... but thanks Billion Happy Travelers from Cali.

Nothing like purchasing a vehicle from 400 miles away sight unseen. Chase Hopper and the team at Billion Sioux City made it very easy. From first contact I could tell the staff was well trained and very professional. From first contact to having the vehicle delivered the whole process took under 48 hours. Even after a 400 mile drive the vehicle looked perfect. With the inventory concerns nationwide at this time they had a great selection and had what I was looking for. I would highly recommend Billion in the future.

1st time using the service. Didnt know what to expect and/or do.

Im seriously upset right now. Rude, heartless, inconsiderate staff. My boyfriend got our car towed here because our babysitter lost our vehicle keys while on an outing with the kids. I took an expensive taxi to get there, was told to go look for my car in the back lot to make sure its there then just go to parts. So I went and looked for myself, found it, got horrible, rude customer service, a key that was not programmed, and an expensive fee for a key that only set my alarm off. I go inside to be chastised, talked down to and demeaned by the staff. They are apparently too busy. They literally treated me like a roach. Disgusting, lazy, inconsiderate behavior from start to finish.

Had to take my vehicle in for a warranty issue and service. Had a subsequent problem show up...that being said my issues were promptly and professionally addressed by Brian Haiar. Brian and the shop technician who assisted him went above and beyond to assist me and take care of my issues. Thanks to all!!

Red and Brian were awesome. Their process was very professional and educative.

Tom Wilson was very good to work with. We now have 2 vehicles from Billion GMC/BuickBob & Lisa Daily

Jesse was a very accomodating, supportive and honest salesperson. He did not try to push me into buying something that I did not want. He took time to make sure that I learned the features of my car, which was really nice!Jason also ensured that I was happy with my purchase when I went to complete the paperwork and pick it up.Overall, it was a great team to work with!

Bobby was an awesome salesman. Kept in touch, no pressure, was patient and answered our questions. Had a smile when we left

Although my appointment was disorganized due to communication from my sales person, the service department accepted my vehicle and completed the work that needed to be done in a timely manner. The service department was fantastic to work with and explained everything and made it easy to understand.

Adir was out of town for 1 week when I first contacted him. He followed up as soon as he was back in the office. Loved the selection of the used gmc and Chevy truck inventory, but love my 2021 Sierra more.

Friendly and not trying to be pushy and got me an appointment for the next day which worked out perfectly since I live 2hours away.

I had a problem with a past service, and the Service Manager fixed it and comped my visit.

Jeff made it an extremely easy process. Had everything set up and ready to go prior to me coming in to look at a vehicle!

Rude staff (Josh) regarding what was wrong with the car and when it would be done. Dan then called back and tried to resolve the issue. Very unhappy. I will not recommend this service center

Adam Limmer is an excellent representative for Billion Buick GMC at Sioux Falls, SD. He was so patient and explained everything in a way that was easily understood by a couple who was not tech savvy!! We will recommend his services to anyone we direct to your dealership!

Everyone at the dealership is always friendly! I love being greeted with a smile each time I walk in for either a new purchase or service. There is always somebody there to answer my questions and if a immediate answer isn’t known, there is always follow-up to answer those said questions. Thanks Billion Buick GMC for all you do for your customers!

Terrible service department. Called with a question about my variable output alternator on my 2017 Chevy Silverado that I bought there for $40,000 dollars and god forbid they put a tech on the phone to answer one simple, non diagnostic question. The guy on the phone was too incompetent to answer it himself. Then he hung up on me despite me being perfectly polite. Never buying another vehicle from this corporation again. Once they send you out the door with a purchase, they never want to see you again unless its to buy another vehicle. Every single interaction Ive had with this service department has been less than pleasurable. They also put a one year expiration on the two free oil changes you get when you buy a new vehicle. It takes full synthetic which is rated for 7,000 miles according to the manual. Most people wont drive 14,000 miles in one year. I had them change mine at 3k for break in purposes and they expired my second oil change. Ive had my pickup for three and a half years. Ive only put 11,500 miles on it in that entire time and change the oil only once a year, long before the 7k miles suggested limit. Screw Billion automotive

Very friendly service. Would definitely buy through them again.

Very nice place, very helpful when our truck broke on our trip, Casey Bassett was very professional and great service advisor.

My service advisor Danny was over the top!! Very helpful and courteous!! Followed up with everything!! I even got a ride home when I dropped my vehicle off!! Great job Danny!! Thank you!!

It was good staff was friendly and very helpful

The serivcethe service was great.

I have purchased several vehicles from Billion GMC and have been completely satisfied with the sale and service after the sale. I have used the same service team for years and now they have a new service advisor Brian who I just met as I brought two of my vehicles in for service. He is a great guy and I appreciate him and his team for the great service

Dan D. in service depart does a excellent job of taking care of my vehicles.

I would rate them 0/5 stars if I could. I was promised via text message that my HVAC blower motor and control panel would be replaced free of charge since the air conditioning went out less than one week after purchasing the vehicle. That promise was not kept, and I instead had to pay nearly $1,000 for these two parts. I will not be returning to this dealership, or any other Billion-owned business.

Said it would only take an hour to fix the part that need it. So I decided to wait there until it was done. It took an hour and a half longer than they said it would. They did not come tell me it was done. I went in to see if it was finally done and the service guy was chatting with a coworker. I was not happy at how long it took. I would not have sat at the dealership for 2.5 almost 3 hours had I known it would take that long.

Bobby did an amazing professional job of explaining all of the options & very good at his job!

Our vehicle broke down with 7 horses in trailer. The team at Billion from Shane in service to Jeff in sales to the team that put some new options on the truck we traded our old one in for was AMAZING. Everyone was kind, helpful and focused on getting us on our way to our vacation. The team at Billion was focused on Helping us decide to repair or purchase with no pressure, just support. The team even accommodated our 7 horses in the side lot and lot so we could be near them and the readying of our new truck. Glad we could offer the Neighborhood horse rides in return for everyone’s goodwill from Billion.

I received Excellent service at Billion Automotive !! I found a great deal on their website on 2018 toyota highlander. They worked with the price and helped me out financially with purchase of flight to come out to get the car. I Had someone pick me on up at the airport. Im am very satisfied with this dealership and the service they provided.

Dan Dunagan is a fantastic service manager. Attention driven and always keeps his customer aware of what is being done to their vehicle.

We drove from Northern Colorado to pick up our new truck. Nowhere within 500 miles of us had the vehicle we were looking for and most we contacted weren’t willing to move much on the price right now. We worked with Jesse McGraw and 90% of the transaction was handled over the phone. He was willing to answer all of my questions and we were happy with the price we negotiated. Jesse’s diligence to make sure our 9hr Drive was worth it made us confident that the transaction would go as planned. No complaints and very much appreciate the attention to detail and no surprises. We were in and out in less than an hour, including a test drive.

Windshield mirror was put back on but has fallen off already!!

Got right in and the work was done quickly and correctly.

Great service! Great people!

Great dealership with great employees.

My work truck went down, found the truck over 300 miles away closest one, made a phone call. Talk to Jesse and made miracles happen, he help me out every step and shipped the truck up to me big thanks!

Parts department went above and beyond today. I ordered a part online. It came in today and found out it was the wrong size. Billion had it in stock and exchanged it without any hesitation. This was completely my fault and they didnt have to do the exchange but they did. Great customer service!

2020 GMC 3rd time since owning it for 5 months. Truck was in the shop for 3 weeks for repair. Very little communication.

From the phone call to come in and take a look , to leaving with my new truck was awesome.I want to thank Ehab and Adir for there great service they provided along with the great knowledge of the product I was looking to purchase.. I was a pleasure to deal with everyone involved .Thanks Billion , keep up the great work.

Jason Donovan and his team were great to work with. First time GMC owner.

The Salesman, kept me informed on details about the truck and time it would be delivered, all and all very happy with the job he did !!

Very pleasant and professional. Service was prompt.

When Denver did end up buying a vehicle this year but we did get excellent service and a knowledgeable salesperson.

Purchased used truck, had to bring in for transmission issue. Fix seems to have worked and tech seemed to know the issue right away.

Jesse was a good salesman to work with, very helpful and got things done quickly.

After dealing with other dealerships for months and getting nowhere with them I contacted Billion. Within days I was driving home with a new vehicle. It was a very quick process

Had the truck oil changed, done fast and efficiently

No wait and service was excellent.

Service Dave, did not talk down to us, helpful and accommodating...…

Aaron is the best! I wouldnt take my vehicle anywhere else!

The service department has always treated me very well, especially Service Advisor Dan Dunnigan. Friendly, fast, honest and responsive.

Quick courteous service

My husband and I were going to look at a car and we had to take our 3 year old and 18 month old. We were hesitant about even going, but our salesperson, Lee, was very nice, non judgemental, and made us feel like we were very welcomed. It was a very long day there and he was so helpful by giving my kids ice cream bars, balls to play with and even keeping them entertained while we had to move our things into the new car. He was also very straight with us about prices and what was best for our family. We had been to a few other dealerships where the salespeople looked annoyed with my kids or rushed through everything just to get us out. I would reccomend this place to anyone and highly recommend Lee!

They were so amazing, especially Julie in Parts! She got me hooked up with what I needed and the guys in service got me going again.

The fastest and easiest time I ever had buying a truck.This is my 12th purchase from billion and will continue our relationship as a family with them.

They went through my personal belongings while they did my oil change, they spilled coffee in my door .. and not one manager will call me about this

I dealt mostly with Josh Roythrone from Chevrolet. He was awesome! Friendly, personal and listened to my wants instead of trying to push a vehicle on me which has happened recently. Gmc personnel very friendly and helpful.

Bought truck Brand new from billions. Haven’t had a good experience with them since I wrote the check. I was In today service write told me twice he was 100% sure there was nothing he could do for me. He was 100% proven wrong by his own coworkers. I feel bad for people that actually trust what these guys say.

Dealership didn’t necessarily listen to our concerns and we had to ask several follow up questions to see if they looked into the specific issue. Which, they did not. Finally got it resolved.

I try to like them but they just make it so hard. Theyve got a big selection which is easily their best quality and why Ive bought from them multiple times. However, theyre customer service and follow through are terrible. I left multiple messages regarding new car paperwork and car repairs that NEVER got returned. The level of customer service drops to almost nothing as soon as soon as youve signed your contract. Ive got two kids that will be in need of a car within a few years and I think Ill probably try to go with a different dealer next time.

Great service at the GMC accessory department.

Bring my GMC here to get all maintenance done. They do a great job and Dan Dunnigan is the man to talk to.

Worked great with us, especially across two states.

This is my 3rd vehicle purchase from Billion as a company. The first two were new vehicle purchases, and this was my first used vehicle purchase from them.First the good:*Cole was the sales person I happened upon when I was interested in test driving a Kia Sportage. He was friendly and accommodating to get me the vehicle to test drive.*After the test drive, I was interested and so we decided to run numbers to see where we were at. We did go back and forth a bit on my trade, but eventually came to an agreement.*The sales process wasnt what I would call high pressure, but I generally know exactly what I want before I even test drive a vehicle. So there wasnt pressure to look at multiple different vehicles, and I was pretty upfront about that. Cole was easy to work with.*Cole and the team stayed pretty much until close to get the paperwork done and I ended up driving home with my Kia that night.Now the meh:*I hadnt gotten 10 miles down the road in my test drive before the fuel light came on. I was pretty unimpressed with that. In fact, it caused an issue when I was trying to figure out why a feature (remote start) wasnt working. That was a deal-breaker feature, and it wasnt working because the fuel level was too low. I almost walked because of that, but they figured it out before it got to that point.*Please re-train your used car detailing team. Especially the employee in charge of the SuperSoaker filled with ArmorAll who apparently sprayed the ENTIRE interior with that disgusting, greasy garbage. Every surface was just freaking gross. It is a legitimate safety issue, as well, because my hand slipped completely off the steering wheel! Needless to say, I spent over an hour scrubbing down the hard-touch surfaces with a Dawn dish soap mix and a rag. I pulled up the rubber cup holder insert to find AmorAll pooled up under it. So, next time Id appreciate not having to clean up the Exxon Valdez oil spill in my new-to-me vehicle. Where can I send the invoice for my car detailing consulting fees?*The loaner I was given while they completed the work due part of our sales agreement was also a victim of the SuperSoaker enthusiast.Overall, the experience was pretty good with the exception of a couple of rough edges that just shouldnt have been an issue with a company this large. Attention to detail is why I would give my business to Billion over Bobs Gimmicky Car Emporium. Thats the reason for my 4/5 star review.

Always a pleasureThe Receptionist is wonderful gal and efficient

Had vehicle taken in to get worked on. Came back with broken gas gauge and lost our garage door opener. They said not their problem. Will never do business at this place again. Straight garbage.

Their quick bay is great. No appointment needed for oil changes and simple stuff. I just needed a new cabin filter. The waiting area is pleasant and has fruit, pastries, and drinks. 🙂

Recently was in to look at a Buick Encore Essence. We we’re helped by Tom, who was extremely nice and very knowledgeable on all the product being sold by both GMC and Buick. If you’re looking for a nice AWD vehicle, definitely stop in and give Tom a visit. I highly recommend the Encore !

Billion Auto has always done a great job supporting our fleet.I would recommend them to anyone.RF Jarding - President - Electric Supply Co., Inc.

Way too expensive!!After all its just a key, programing is not difficult and doesnt take extensive training.
