Is the 2020 INFINITI QX80 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The QX80’s appeal comes from its straightforward, durable-feeling formula: a powerful V8, a comfortable ride, and a premium cabin that still feels upscale. The expert notes also point to a capable, heavy-duty character that can handle towing and rougher surfaces without much drama.

Its V8 powertrain is described as able to handle the load, and the SUV’s rear auto-leveling suspension helps keep the ride composed and level when towing. Infiniti also backs the QX80 with a four-year/60,000-mile basic warranty and a six-year/70,000-mile powertrain warranty.

For used buyers, the biggest long-term ownership risk is that its age and fuel consumption can make it more expensive to live with over time.

What should I look for when buying a used 2020 INFINITI QX80?

At 68% 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 thorough pre-purchase inspection, especially if you’re considering a higher-mileage example. Focus on overall condition, signs of prior bodywork, and whether the cabin and electronics still feel consistent with the asking price.

Key things to evaluate:

• Trim level: The QX80 is sold in Luxe and Limited trims. The exterior refresh brings welcome lights, power-folding auto-dimming heated mirrors with integrated LED turn signals, LED fog lights, headlight washers, adaptive front lighting, LED taillights, and automatic on/off LED headlights with high beam assist. Limited-grade models add matte silver and open-pore Ash wood trim, while some top-tier paint choices are reserved for the upper model.
• Powertrain: Every QX80 uses a 5.6-liter V8 with a seven-speed automatic transmission and manual-shift mode. It makes 400 horsepower and 413 pound-feet of torque, and the rear-wheel-drive version returns 14 mpg city and 20 mpg highway, while four-wheel drive lowers those figures to 13 mpg city and 19 mpg highway.
• Safety package: Standard equipment includes automatic emergency braking, rear cross-traffic alert, pedestrian detection, forward collision warning, rear parking sensors, a surround-view camera system, and automatic collision notification. Available upgrades include blind-spot monitoring, lane-departure warning, adaptive cruise control, distance-control assist, and lane-keep assist.
• Infotainment: You get an 8-inch upper touch screen and a 7.0-inch lower touch screen, plus Apple CarPlay, Android Auto, navigation, satellite radio, Bluetooth, keyless entry, remote start, tri-zone climate control, a moonroof, a CD player, four USB ports, and a 13-speaker Bose stereo. Available upgrades include two 8.0-inch displays, a rear-seat entertainment system, and a WiFi hot spot.
• Fuel efficiency: The rear-wheel-drive model gets 14 mpg in the city and 20 mpg on the highway, while the four-wheel-drive version gets 13 mpg city and 19 mpg highway.

Which 2020 INFINITI QX80 trim should I buy?

The 2020 INFINITI QX80 is offered in 2 trim levels: Luxe and Limited.

Here's the short version:

• Luxe: This is the trim to target if you want the core QX80 experience without stretching to the top model. It already gives you the big V8, the dual-screen infotainment setup, Apple CarPlay, Android Auto, navigation, and the full set of standard driver-assistance features. It’s the best-value choice for most shoppers.
• Limited: Choose this if you want the more upscale presentation and are willing to pay for it. It adds a richer cabin treatment with matte silver and open-pore Ash wood trim, and it comes standard with four-wheel drive.

The safety package includes automatic emergency braking, rear cross-traffic alert, pedestrian detection, forward collision warning, rear parking sensors, a surround-view camera system, and automatic collision notification.

Is now a good time to buy a used 2020 INFINITI QX80?

This is a moderate market for selective buyers, with enough inventory and pricing softness to make comparison shopping worthwhile.

• Deal availability: 36.1% of listings are priced as good or great deals.
• Inventory: There are 615 listings available.
• Price trend: Prices have softened 15.22% compared with last year.
• Clean inventory: 68.0% of listings are accident-free.

If you find a listing below $21,798, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 INFINITI QX80's resale value?

The current average of $21,900 sits slightly below last year's $25,830.

That price movement suggests the QX80 has already absorbed a meaningful amount of depreciation, which can help future resale stability if you buy at the right price. If you keep the vehicle in strong condition and avoid overpaying now, you may have a better chance of limiting your loss later.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 INFINITI QX80 safe?

The Infiniti QX80 earns good scores in the moderate overlap front and side crash tests from IIHS, and the National Highway Traffic Safety Administration rates it as having better crashworthiness from the side than the front and a moderate risk of rollover during a crash.

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

Standard safety features include automatic emergency braking, rear cross-traffic alert, pedestrian detection, forward collision warning, rear parking sensors, a surround-view camera system, and automatic collision notification. You can add blind-spot monitoring, lane-departure warning, adaptive cruise control, distance-control assist, and lane-keep assist.

One caveat is that this is an older model, so it doesn’t offer the full set of newer driver-assistance technology found in some rivals.

Should I buy a 2020 INFINITI QX80 or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 36.1% of listings are priced as good or great deals.
• At 68% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 15.22% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It pairs a refreshed luxury feel with a powerful V8 and a comfortable ride.

Consider the 2019 if:

• At $20,332, the 2019 costs less than the current year's $21,900 average.
• It’s a plush, old-school luxury SUV with decent shelf appeal.

Consider the 2021 if:

• At $28,505, the 2021 costs more than the current year's $21,900 average.
• It adds small updates and a reshuffled trim lineup with a more current cabin feel.

The bottom line: The 2020 is the right pick if you want the refreshed luxury look and strong V8 character at a lower used price than newer examples. If you’re more price-sensitive, the 2019 can save you money while keeping the same basic formula.
