Used INFINITI QX80 for sale near Frisco, TX under $1,000,000

Every person we encountered was friendly and helpful. The buying process was trouble-free. The follow up by our sales associate Jovanny was excellent too.

I am so pleased with this truck and this is the 3rd one that I have purchased from this same dealership. The staff really went far and beyond to find me the exact model that I want.

Just finished another service visit on my M8 and as always, Nathan Meyers was great. Friendly, always on time, very knowledgeable and went out of his way to explain what was needed. There is simply no better place if you own a BMW. I will always come here for service. Thanks Nathan

Never had issues with service. I got a loaner and they kept the car for diagnostics. All fixed and excellent service. Thankyou Adrian m!

I bought the car recently. I would recommend if you want a nice interior and don't need all of the fancy tech that are in the newer rivals. I like the off road capability as we drive on the beach a lot and occasionally have to drive on some tougher trails. The comfort is really good though not quite as good as the new GMC Yukon Denali with the air suspension. The interior is reasonably plush but not as nice as the Navigator. It is just a step above the new Expedition or on par with the Yukon Denali. The main reason I bought the QX80 was for its off road capability. We have already done some moderate off roading and it performed flawlessly. The power is adequate. Not fast, but plenty for almost everyone. The only complaints are that the transmission is a bit lacking on gears.

My sales representative was Shawn. He was excellent. No pressure, easy to work with. He made the buying experience very pleasant. I would be happy to recommend him to other buyers.

So far I'm in Love with the Car. Comfortable Tight Vehicle. I gave the Cadillac Escalade a try for years and they just simply disappointed me . QX80 is a winner.

Customer service was excellent, answered all my questions . I was very satisfied with the overall experience.

Drove nissans and Toyota my whole life..I was looking for an armada but got the luxury version instead which is the QX80. Very luxurious in and out my only gripe was the infotainment which is severely outdated with no android auto or Apple car play. still this big girl has plenty of power and the V8 is intoxicating lol which I'm loving. THIS truck isn't meant for fuel economy, if you want that, get a hybrid. Very reliable and luxurious. Hermosa Blue is plainly gorgeous for this truck.

Was greeting the moment I drove in. Definitely good Customer service they were able to turn a bad situation to a good experience. John and Ezekiel were very helpful in getting my car in to get worked on. Will definitely be coming back

I LOVE the Grubbs dealership. They always take such good care of my car and make things go smoothly when it's in the shop. I had quite a bit of work done this time and I couldn't be happier with the outcome! Chas Velarde was one of the most outstanding service advisors I have ever worked with. He really listened to my concerns and he has such a wonderful attitude. The entire staff, from the front desk, to the attendants who bring your car to you, are always so nice to deal with. I feel lucky to have bought my car from Grubbs and will always bring my car, that I love, to them for service.

I recently purchased a 2025 Infiniti QX80 at an excellent price. Even at full price, it offers good value in the full-size luxury SUV market. After one month, here's my assessment. Strengths **Styling**: The QX80 features elegant exterior and interior design that outshines most competitors. The Navigator's redesign was disappointing, while the Wagoneer lacks refinement. Only the Escalade matches its presence, though with a more aggressive look. **Value**: Infiniti's current market position creates pricing advantages. Feature-for-feature, the QX80 is thousands less than competitors across all trims. **Powertrain**: The twin-turbo 3.5L V6 delivers smooth power through a 9-speed transmission. I'm averaging 20-21 mpg in mixed driving (better than EPA estimates), though it requires premium fuel. **Comfort**: Ride quality and noise isolation are excellent for a body-on-frame vehicle. The air suspension mitigates most harshness from the 22" wheels. **Handling**: It drives more like a midsize SUV, handling mountain roads with unexpected confidence. Only the pricier Escalade V offers better dynamics. **Space**: Dimensions match standard Navigator and Escalade while exceeding the Lexus LX. The third row comfortably fits adults with easy access, and cargo space is generous, especially with seats folded. **Towing**: All models can tow 8,500 pounds, above segment average. Only Wagoneer models with Hemi V8s offer more. Weaknesses **No Homelink**: Inexplicably lacks the standard garage door opener system. Instead uses "myQ," requiring compatible equipment and Wi-Fi. It works roughly 20% of the time for closing, 50% for opening. **Missing Trailer Brake Controller**: Despite strong towing capacity and pre-wiring, it lacks this essential safety feature that the cheaper Nissan Armada includes standard. **No Rear Sunshades**: A premium family vehicle should include this feature, common in less expensive SUVs. **Limited Storage**: Few interior storage options beyond a modest console and small pass-through. The Autograph trim's "cool box" reduces console space by half while offering minimal functionality. **Software Issues**: I've experienced two significant electronic failures already. Once, the infotainment rebooted while driving. More concerning, at 1,200 miles, the dashboard, HVAC, and air suspension failed simultaneously—a potentially dangerous situation. Uncertain Factors **Reliability**: Infiniti typically outperforms Nissan, and Japanese production suggests quality. The VR-series engine appears promising, but competitors have documented issues too. Air suspension systems generally develop problems after several years. **Resale**: Likely below Lexus but competitive with Navigator and slightly below Escalade. Verdict I'm satisfied with my purchase, especially given local dealership availability and favorable pricing. The electronic issues create some concern for long-term ownership. For shoppers prioritizing style, value, and driving dynamics who can accept some feature omissions, the QX80 deserves consideration in this competitive segment.

Isaac Marquez was my salesman. This young man was very attentive to my wants in a new car. He found the perfect vehicle for me. I met several of his team members and they were all wonderful. I will recommend this dealership and Isaac to all my family and friends. Thank you, Grubbs Infiniti.

I just bought the QX80 and only having it 3 days, i really like it. It is quite, runs smooth, still trying to figure out all of the options, (i.e.) radio, navigation and hands free cell phone, but I will get there soon. I know the gas mileage is not great, but that's ok for now. I have no major complaints as of now

Comfort, power, space, looks - the Infiniti GX80 has it all for my family. We needed space and we got it. Infiniti added style and comfort. I'm very happy with this vehicle - both on the highway and around town.

Great Customer service. My salesman was very informative, courteous and pleasant to work with. Thanks

I came to this car from a 2016 Yukon which was a rolling dumpster fire. At 102k miles, I haven’t had a single failure with this car. It tows extremely well, the seat comfort is by far the best I’ve ever owned, I don’t love the exterior styling, but its such a great owner experience that it doesn’t matter. Maintenance is like owning a Camry, cheap and infrequent. AWD system makes driving in all conditions a breeze. Great vehicle.

The best way I can describe this dealership from both sales and service is to say that it is the way customer service should be done. The values placed on the consumer is something both old world in terms of respect, and new world in terms of how to manage the experience and maintain long term relationships with their consumer. My vehicle was bought used and needed service six months after purchase. I must commend both the service writer Jessiel Cortez and the service manager Krista Polito for their professionalism and kindness above all expectations. I am immensely happy with my decision to both buy my vehicle from Sewell, and trust their service department to manage my automotive experience. To put it simply: I don’t know why anyone would go anywhere else for a car.

Very professional group of people. They did a great job of contacting me and following up. Sent me all the info I needed for the vehicle I was interested in.

Response received from the dealership was very quick. Everyone at Sewell Infiniti was friendly and attentive all of our inquiries. Vehicle was exactly as displayed in pictures and great purchase experience completed in 2 hours!

This SUV is incredible. It's very quick, quiet, and it's extremely comfortable. Combine that with the best looking exterior in its class and the fact that it's 10x better than the previous model and it's a winner.

Awesome experience!! My wife and I were treated with respect and kindness. They are definitely everything their commercials say they are!

We had a great experience. Nicole was honest and the pricing was very transparent. Even though we are several states away, we would absolutely work with Nicole and Sewell again.

Overall our sales experience was a five stars. The reason for the five stars is because of our car salesman Jimmy he was great. Very attentive and outgoing to earn our business. The reason for the four stars is because I hate haggling with finance for all weather floor matts when were buys a 40 K plus car.

QX 80 is very comfortable driving. Despite it's size, maintenance is great. Thieves often mistaken the rear gatelift cover to be something valuable hidden inside thereby forcing it open and causing damage. May be a sign may be necessary. The current look is nice but attractive to thieves who have no idea of what it is.
