How much does the 2021 INFINITI QX80 cost?

Prices have softened 12.55% compared to this time last year, making it a favorable time to shop this model year.

There are 496 listings available, which suggests you have some room to compare prices and equipment.

If you find a listing below $29,668.81, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 INFINITI QX80 a good car?

The 2021 INFINITI QX80 makes sense if you want a large luxury SUV that prioritizes comfort, space, and a traditional feel over modern polish. It earns a 3.8/5 user rating and a 7.33/10 expert rating.

The model scores 8/10 across Look and feel and Performance.

Owners repeatedly praise the comfortable ride, smooth driving experience, and refined interior. They also appreciate the improved features and premium cabin materials.

The trade-offs are clear: the expert notes call out poor fuel economy and poor handling, and owners mention limited entertainment content in lower trims. That means you should view it as a relaxed, upscale cruiser rather than a sharp or efficiency-focused SUV.

For you, the QX80 fits best if you want a full-size luxury SUV with a roomy cabin and a more truck-like foundation. The market shows 29.8% of listings as good or great deals, which gives you some leverage if you shop carefully.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80 leans into a proven, old-school formula with body-on-frame construction and a naturally aspirated V8, which can be appealing if you want a simpler long-term ownership profile.

Owners describe it as comfortable, refined, and smooth, and the review summary points to a luxurious and comfortable ride with a refined interior. That kind of feedback matters because it suggests the truck-like platform is delivering the relaxed, dependable character many buyers want from a big SUV.

The expert notes also support that impression by emphasizing the QX80’s straightforward mechanical setup and its ability to handle highway driving with ease. Infiniti’s warranty coverage includes a four-year, 60,000-mile basic warranty and a six-year, 70,000-mile powertrain warranty, which adds some peace of mind for used buyers.

For long-term ownership, your biggest risk is not complexity so much as age-related wear, especially if the vehicle has been used hard or maintained inconsistently.

What should I look for when buying a used 2021 INFINITI QX80?

Accident-free inventory is solid at 76.6% — always verify the vehicle history report.

You should still check the history report carefully, because a clean title alone does not tell you how the SUV was maintained or repaired. A thorough inspection should focus on the cabin, electronics, suspension behavior, and signs of cosmetic wear, since owners have noted cosmetic issues in some vehicles. It also helps to confirm that the features you want are actually present, especially on lower trims.

Key things to evaluate:

• Trim level: The base Luxe trim rides on 20-inch wheels, while Premium Select and Sensory get 22-inch wheels. The interior uses leather upholstery, but Sensory adds perforated semi-aniline leather, and lower trims may leave you wanting more equipment.
• Powertrain: All models use a 5.6-liter V8 with a seven-speed automatic transmission. Rear-wheel drive is standard, and four-wheel drive is available.
• Safety package: Standard equipment includes adaptive cruise control, blind-spot monitoring, lane-departure warning, lane-keep assist, forward collision warning, automatic emergency braking with pedestrian detection, and Backup Collision Intervention.
• Infotainment: The standard setup uses 8.0-inch upper and 7.0-inch lower touchscreens, plus Apple CarPlay, Android Auto, a built-in WiFi hotspot, navigation, Bluetooth, SiriusXM, and a 13-speaker Bose audio system.
• Fuel efficiency: EPA ratings are 16 mpg combined, 14 mpg city, and 20 mpg highway with rear-wheel drive, or 15 mpg combined, 13 mpg city, and 19 mpg highway with four-wheel drive.

Which 2021 INFINITI QX80 trim should I buy?

The 2021 INFINITI QX80 is offered in 3 trim levels: Luxe, Premium Select, and Sensory.

Here's the short version:

• Luxe: This is the entry point, and it gives you the core QX80 experience with the standard V8, leather upholstery, dual-screen infotainment, and the full suite of standard driver-assistance features. It makes sense if you want the QX80’s size and comfort without paying for extras you may not need.
• Premium Select: This trim adds a more upscale look and 22-inch wheels, making it the better middle-ground choice if you want a richer appearance without jumping all the way to the top model.
• Sensory: This is the most luxurious version, with perforated semi-aniline leather, 22-inch wheels, and Hydraulic Body Motion Control. It suits you best if you want the most polished ride and the richest cabin, but it is not the value pick.

The safety package is standard across the lineup, so you do not need to move up a trim just to get the main driver-assistance features.

Is now a good time to buy a used 2021 INFINITI QX80?

This is a moderate buyer’s market, so you can shop selectively and still find room to negotiate.

• Deal availability: 29.8% of listings are priced as good or great deals.
• Inventory: There are 496 listings available.
• Price trend: Prices have softened 12.55% compared with last year.
• Clean inventory: 76.6% of listings are accident-free.

If you find a listing below $29,668.81, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 INFINITI QX80's resale value?

The current average of $29,648 sits slightly below last year's $33,903.

That decline suggests the QX80 has softened in the market, which can help you as a buyer today but may limit what you recover later. If you plan to sell in a few years, you should expect resale value to depend heavily on condition, mileage, and equipment.

The good news is that the current pricing gives you a lower entry point than last year’s market. The downside is that a vehicle with a softer price trend can also mean slower appreciation of premium features when it comes time to trade or sell.

Is the 2021 INFINITI QX80 safe?

The National Highway Traffic Safety Administration (NHTSA) gave the 2021 Infiniti QX80 a four-star overall safety rating, with five-star ratings for side crash tests, four-star ratings for frontal crash tests, and a three-star rollover rating.

It earns a 7/10 safety score from our experts.

Standard safety equipment includes adaptive cruise control, blind-spot monitoring, lane-departure warning, lane-keep assist, forward collision warning, automatic emergency braking with pedestrian detection, and Backup Collision Intervention. That is a strong standard list for the class, especially because Infiniti makes it standard rather than optional.

The main caveat is the three-star rollover result, which is worth keeping in mind if safety is a top priority for you. The IIHS did not test this vehicle.

Should I buy a 2021 INFINITI QX80 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 29.8% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.6% — always verify the vehicle history report.
• Price trend: Prices have softened 12.55% compared with last year.
• It keeps the old-school body-on-frame character while adding small updates like the improved Smart Rearview Mirror.

Consider the 2020 if:

• At $22,916, the 2020 costs less than the current year's $29,648 average.
• It emphasizes comfort and capability with a more luxurious feel than the Armada.

Consider the 2022 if:

• At $36,974, the 2022 costs more than the current year's $29,648 average.
• It adds a larger 12.3-inch display with wireless Apple CarPlay and more modern convenience tech.

The bottom line: You should focus on the 2021 if you want the best balance of current pricing, standard safety equipment, and traditional full-size SUV character. If your budget is tighter, the 2020 can save you money, while the 2022 is the better path if you want newer tech and can pay more for it.
