Is the 2021 Nissan Altima reliable?

The owner feedback points to a car that feels quality-built, comfortable, and easy to live with over time.

The expert review also emphasizes the Altima’s broad appeal and the sense that it has been steadily improved over time, which supports confidence in its day-to-day durability. If you buy used, the main long-term risk is less about a single glaring flaw and more about choosing a well-kept example with the right equipment and condition.

What should I look for when buying a used 2021 Nissan Altima?

At 67.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. After that, prioritize a pre-purchase inspection so you can check for signs of uneven wear, poor repairs, or neglected maintenance. Focus on overall condition and equipment level, since the Altima’s appeal can vary a lot depending on how it was optioned.

Key things to evaluate:

• Trim level: The base model feels a little stripped-down, while higher trims add better interior materials, stitching on the dash and seats, and a more polished cabin feel.
• Powertrain: Most versions use a 2.5-liter four-cylinder with 182 horsepower and 178 pound-feet of torque, while the SR VC-Turbo uses a 2.0-liter turbo four-cylinder with 248 hp and 273 lb-ft for stronger performance.
• Safety package: Nissan Safety Shield 360 includes automatic emergency braking with pedestrian detection, rear automatic braking, rear cross-traffic alert, blind-spot warning, lane-departure warning, and high-beam assist. It is standard on every Altima SV and above, so base-trim shoppers should verify equipment carefully.
• Infotainment: The standard touchscreen is 8 inches on most trims, wireless Apple CarPlay and Android Auto are standard on all but S models, and Nissan Door to Door Navigation with five-year trial access to Premium Traffic is standard on Platinum and optional on other trims except S.
• Fuel efficiency: The 2.5-liter engine is rated at 28 mpg city and 39 mpg highway with front-wheel drive, while the VC-Turbo is rated at 25 mpg city and 34 mpg highway.

Which 2021 Nissan Altima trim should I buy?

The 2021 Nissan Altima is offered in 5 trim levels: S, SV, SR, SL, Platinum.

Here's the short version:

• S: This is the least expensive way into the Altima, but it is also the most stripped-down version, with the lowest levels of tech and safety equipment. It makes sense only if your priority is the lowest entry price.
• SV: This is the best-value trim for many shoppers because it adds Nissan Safety Shield 360 and a more complete feature set without jumping too far up the price ladder.
• SR: This is the sweet spot if you want a more appealing mix of equipment and style, including 19-inch alloys and paddle shifters, while still staying below the luxury-oriented trims.
• SL: This is the right choice if you want a more premium ownership experience, with NissanConnect Services, Bose Premium Audio, and ProPilot Assist.
• Platinum: This is the most fully equipped Altima, adding 19-inch aluminum-alloy wheels, an around-view monitor, ProPilot Assist, leather seating appointments, and more.

Safety Shield 360 is standard on every Altima SV and above.

What is the 2021 Nissan Altima's resale value?

The current average of $16,177 sits slightly below last year's $17,730.

That softer pricing suggests the Altima has become more accessible for used buyers, but it also means future sellers may face a more competitive market. If you buy now, you may benefit from the lower entry cost, but resale gains are likely to depend on condition, mileage, and equipment rather than broad market appreciation.

Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Nissan Altima 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:

• 29.5% of listings are priced as good or great deals.
• At 67.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.76% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.
• The 2021 Altima offers all-wheel drive, multiple powertrain options, and wireless Apple CarPlay and Android Auto.

Consider the 2020 if:

• At $14,158, the 2020 costs less than the current year's $16,177 average.
• It adds broader availability of Nissan Safety Shield 360.

Consider the 2022 if:

• At $17,277, the 2022 costs more than the current year's $16,177 average.
• It expands Midnight Edition availability on the SR trim.

The bottom line: The 2021 is the right pick if you want a well-rounded Altima with strong owner satisfaction and a softer used price than newer models. If you are especially price-sensitive, the 2020 is the better value play; if you want a newer setup and can spend more, the 2022 is the step up to consider.
