Used 2021 INFINITI QX80 for Sale near California

How much does the 2021 INFINITI QX80 cost?

Prices have softened 10.97% compared to this time last year, making it a favorable time to shop this model year.

There are 489 listings available, which gives you a meaningful amount of inventory to compare.

Is the 2021 INFINITI QX80 a good car?

With a 3.8/5 user rating and a 7.3/10 expert rating, the 2021 INFINITI QX80 lands in the range of a capable luxury SUV with clear strengths and clear compromises. The model scores 8/10 across Look and feel and Performance.

Owners repeatedly praise the luxurious and comfortable ride, the smooth driving experience, and the refined interior. The QX80’s full-size layout and premium materials also fit its role as a large luxury SUV, and the overview points to a model that blends upscale comfort with rugged capability.

The trade-offs are just as consistent: poor fuel economy and poor value for money come up in expert and owner feedback, and the driving experience is less appealing if you care about handling. If you want a big, comfortable, premium SUV with a strong presence and you can live with its efficiency and dynamics, it makes sense; if value and agility matter more, you should look carefully at alternatives.

36.4% of listings are priced as good or great deals, so there are some attractive opportunities if you shop selectively.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80 is built around a body-on-frame layout and a proven V8 powertrain, which supports its long-term durability story. Owners describe it as reliable, comfortable, and smooth to drive, and the expert notes emphasize a responsive engine and a relaxed, confidence-inspiring highway character.

The QX80’s dependability is helped by its straightforward mechanical setup and standard safety equipment, and the cost-effectiveness notes point to Infiniti’s four-year, 60,000-mile basic warranty and six-year, 70,000-mile powertrain warranty. For used buyers, the main long-term ownership risk is that repair and operating costs can add up if you’re not prepared for a large V8 SUV.

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

At 71.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially on any listing that looks unusually cheap. Focus on signs of prior body damage, uneven panel gaps, tire wear, and any evidence that the SUV has been used hard or repaired poorly.

Key things to evaluate:

• Trim level: The base Luxe trim rides on 20-inch wheels, while Premium Select and Sensory move up to 22-inch wheels. The interior is dressed up with wood trim, contrast stitching, and standard leather upholstery, with perforated semi-aniline leather on Sensory models.
• Powertrain: All QX80 models use a 5.6-liter V8 with a seven-speed automatic transmission. Rear-wheel drive is standard, and four-wheel drive is available; the engine makes 400 horsepower and 413 pound-feet of torque.
• 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, Apple CarPlay and 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, and 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, Sensory.

Here's the short version:

• Luxe: This is the entry point, but it still gives you the core QX80 experience with standard leather upholstery, the dual-screen infotainment setup, and the full suite of standard driver-assistance features. It makes sense if you want the lowest-cost way into the model.
• Premium Select: This trim adds a more upscale look and feel with 22-inch wheels, making it the better-value choice if you want more presence without jumping all the way to the top trim.
• Sensory: This is the most luxurious version, with perforated semi-aniline leather, 22-inch wheels, and the strongest feature set in the lineup. It suits you if you want the richest cabin and don’t mind paying more for it.

The standard safety package is generous across the lineup, so you don’t need to move up a trim just to get the core 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 worthwhile listings.

• Deal availability: 36.4% of listings are priced as good or great deals.
• Inventory: There are 489 listings available.
• Price trend: Prices have softened 10.97% compared with last year.
• Clean inventory: 71.6% of listings are accident-free.

If you find a listing below $28,407, 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 $28,407 sits slightly below last year's $31,907.

That price movement suggests the QX80 has softened enough to create a better entry point for used buyers, but it also means sellers are facing a less favorable market than they were a year ago. If you plan to resell later, you should expect the model’s value to depend heavily on condition, mileage, and equipment level.

Because the current average is below last year’s level, a clean, well-optioned example should still be easier to justify than a rough one. If you buy carefully now, you may reduce the risk of taking a bigger depreciation hit later.

Is the 2021 INFINITI QX80 safe?

The 2021 Infiniti QX80 earns a four-star overall safety rating from NHTSA, 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 features include 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. Those features are standard rather than optional, which is a strength for a luxury SUV at this price point.

The main caveat is the rollover result, which is lower than the rest of the crash-test performance. If safety is a top priority, you should pay close attention to that rating and make sure the vehicle’s condition and equipment match your expectations.

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:

• 36.4% of listings are priced as good or great deals.
• At 71.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.97% compared with last year.
• It adds a refreshed mirror and a reshuffled trim lineup.

Consider the 2020 if:

• At $21,801, the 2020 costs less than the current year's $28,407 average.
• It emphasizes luxury and comfort over the sibling SUV.

Consider the 2022 if:

• At $35,358, the 2022 costs more than the current year's $28,407 average.
• It adds a larger display and wireless smartphone integration.

The bottom line: The 2021 is the best fit if you want the current-year balance of price, features, and availability. If your budget is tighter, the 2020 is the value play; if you want newer tech, the 2022 is the upgrade path.
