How much does the 2021 Lexus RX cost?

Prices have softened 2.96% compared to this time last year, making it a favorable time to shop this model year.

There are 1,485 listings available, which gives you a solid pool of options to compare.

Is the 2021 Lexus RX a good car?

Yes — the 2021 Lexus RX earns a 4.92/5 user rating, and its expert rating is 7.83/10. The standout strength is Cost effectiveness at 9/10.

Owners consistently praise its reliability, luxurious features, and smooth driving experience. Comfort and handling also come through as recurring positives, which fits the RX’s relaxed, upscale mission. The main trade-offs are that some owners want more storage space and better brake response, while the expert review also notes fairly pedestrian performance and unintuitive technology.

For you, that means the RX makes the most sense if you want a comfortable, well-equipped luxury SUV rather than a sporty one. It’s especially appealing if you value a calm daily driver with a strong reputation for long-term satisfaction.

36.5% of listings are priced as good or great deals, which suggests there are still worthwhile opportunities in the market.

Is the 2021 Lexus RX reliable?

Owners rate it 4.92/5, a strong signal of long-term satisfaction.

The owner feedback repeatedly points to reliability, and it also describes the RX as dependable and smooth to live with over time. The expert review reinforces that theme by noting Lexus’ tradition of reliability and describing the RX as a comfortable cruiser that feels easy to guide in everyday driving.

The cost-effectiveness review also highlights the RX’s value positioning, which matters if you plan to keep the vehicle for years. For used buyers, the main long-term ownership risk is less about durability and more about whether the technology and driving feel still match your expectations.

What should I look for when buying a used 2021 Lexus RX?

At 74.3% 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 careful inspection of body panels, paint consistency, and signs of prior repair. Because the RX is often bought for comfort and family use, it also makes sense to check interior wear, seat condition, and how well the electronics and infotainment functions operate. If you’re comparing multiple listings, focus on maintenance records and overall condition rather than mileage alone.

Key things to evaluate:

• Trim level: The base RX comes with standard 18-inch aluminum wheels, LED lighting, rear privacy glass, integrated turn-signal mirrors, NuLuxe-trimmed seats, power-adjustable front seats, a reclining second row, and a power tilt/telescoping steering wheel. The F Sport adds a more aggressive appearance with unique fascia, F Sport badging, F Sport wheels, and performance-oriented trim details, while the extended-body RXL variants add a third row.
• Powertrain: The standard RX uses a 3.5-liter V6 with 295 horsepower and 267 pound-feet of torque paired with an eight-speed automatic transmission. Hybrid versions use a 3.5-liter V6 with three electric motors and an e-CVT, and they come standard with AWD.
• Safety package: Lexus Safety System+ 2.0 is standard and includes pre-collision warning with automatic emergency braking, pedestrian detection, cyclist detection, automatic high beams, adaptive cruise control, lane-departure warning with steering assist, lane-keep assist, lane-trace assist, and road sign assist. Every RX also includes a rearview camera, 10 airbags, enhanced vehicle stability control, and blind-spot monitoring with rear cross-traffic alert.
• Infotainment: Standard tech includes an 8-inch infotainment touchscreen, voice recognition, Bluetooth, Apple CarPlay, Android Auto, Amazon Alexa, satellite radio, HD Radio, a WiFi hot spot, six USB ports, and a nine-speaker sound system. A 12.3-inch screen is available, but wireless Apple CarPlay and Android Auto are not offered.
• Fuel efficiency: The front-wheel-drive RX 350 returns 20 mpg city, 27 mpg highway, and 23 mpg combined. AWD and RXL versions reduce combined efficiency by 1 mpg, while the RXL with AWD gets 21 mpg combined. Hybrid models return 29 or 31 mpg city and 28 mpg highway, depending on configuration.

Which 2021 Lexus RX trim should I buy?

The 2021 Lexus RX is offered in 5 trim levels: RX, RX F Sport, RXL, RX Hybrid, and RXL Hybrid.

Here's the short version:

• RX: This is the best-value starting point if you want the core RX experience: comfort, strong standard equipment, and the familiar luxury-SUV formula without paying for extra styling or size.
• RX F Sport: Choose this if you want the most driver-focused version, since it adds a sportier look and available handling upgrades, but it’s still more about feel than outright performance.
• RXL: Pick this if you need the extended body and third row, since it adds practicality for families who want more seating flexibility.
• RX Hybrid: This is the efficiency-minded choice, pairing the RX’s comfort with stronger fuel economy and standard AWD.
• RXL Hybrid: Go here if you want the third row and the hybrid powertrain together, though it’s the most specialized option in the lineup.

Lexus Safety System+ 2.0 is standard across the lineup, so you get the same core driver-assistance coverage regardless of trim.

Is now a good time to buy a used 2021 Lexus RX?

This is a moderate market for selective buyers, with enough inventory to shop carefully and enough deal activity to find value.

• Deal availability: 36.5% of listings are priced as good or great deals.
• Inventory: There are 1,485 listings available.
• Price trend: Prices have softened 2.96% compared with last year.
• Clean inventory: 74.3% of listings are accident-free.

If you find a listing below $35,277, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Lexus RX's resale value?

The current average of $35,429 sits slightly below last year's $36,510.

That softer pricing suggests the RX is in a buyer-friendly phase right now, which can help you negotiate if you’re shopping today. For a future seller, it also means resale value may depend more on condition, mileage, and equipment than on market momentum alone. Well-kept examples with strong service history should stand out more clearly when it’s time to sell.

Vehicles with strong owner satisfaction ratings, like this model year's 4.92/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Lexus RX safe?

The 2021 Lexus RX earns a Top Safety Pick designation from IIHS and four-star ratings overall from NHTSA, with five-star side-impact crashworthiness.

It earns an 8/10 safety score from our experts.

Every RX comes with Lexus Safety System+ 2.0, which includes pre-collision warning with automatic emergency braking, pedestrian detection, cyclist detection, automatic high beams, adaptive cruise control, lane-departure warning with steering assist, lane-keep assist, lane-trace assist, and road sign assist. It also includes a rearview camera, 10 airbags, enhanced vehicle stability control, and blind-spot monitoring with rear cross-traffic alert.

One caveat is that the longer RXL and RXL Hybrid versions were not tested by IIHS, so their crashworthiness is less directly verified than the standard RX.

Should I buy a 2021 Lexus RX 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:

• 36.5% of listings are priced as good or great deals.
• At 74.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 2.96% compared with last year.
• Owners rate it 4.92/5 — a strong satisfaction signal.
• It adds new standard safety systems while keeping the RX’s familiar comfort-focused formula.

Consider the 2020 if:

• At $33,162, the 2020 costs less than the current year's $35,429 average.
• It offers comfort, refinement, and a two-row or three-row layout.

Consider the 2022 if:

• At $39,160, the 2022 costs more than the current year's $35,429 average.
• It brings minimal changes, including new colors and a standalone fog lamps option.

The bottom line: If you want the best balance of price, comfort, and standard safety, the 2021 is the sweet spot. If you’re especially price-sensitive, the 2020 can save you money while keeping much of the same core appeal. If you want a newer model-year example and don’t mind paying more, the 2022 is a reasonable step up, but it doesn’t change the formula much.
