Is the 2021 Genesis G90 a good car?

Yes — 5/5 from owners and 8.67/10 from our experts. The model scores 10/10 across Cost effectiveness and Safety.

Owners consistently praise the luxury and value for money, along with the powerful performance, smooth ride, and comfortable interior. The expert review also backs up that appeal with strong value, a refined ride, and serious presence on the road.

The main trade-offs are that it cannot keep up with the competition even at a lower price and has poor handling. Even so, the G90’s deal pricing and overall market position make it a compelling used luxury sedan if you want a lot of car for the money.

With 24.5% of listings marked as good or great deals, you have some room to shop selectively.

Is the 2021 Genesis G90 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction. Reviews also describe it as reliable, dependable, and trouble-free, with buyers appreciating a car they can count on for the long haul.

The expert review reinforces that impression by emphasizing the G90’s solid, well-rounded character and its ability to deliver luxury without drama. It also notes that the first scheduled maintenance visit is on the house, which helps soften early ownership costs.

For used buyers, the main long-term risk is less about day-to-day dependability and more about making sure the specific car has been maintained properly and hasn’t absorbed hidden wear from luxury-car use.

What should I look for when buying a used 2021 Genesis G90?

At 69.8% 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 the car has been repaired or repainted. Focus on condition details that matter in a luxury sedan: interior wear, electronics, ride quality, and evidence of uneven panel gaps or cosmetic repair.

Key things to evaluate:

• Trim level: The G90’s equipment is broadly generous, with heated and cooled quilted Nappa leather seats, a 12.3-inch display, digital instrumentation, and rear-seat comfort features standard across the lineup. The main differences are the powertrain and wheel choices rather than major feature gaps.
• Powertrain: You can choose a 3.3-liter twin-turbo V6 or a 5.0-liter V8, each with rear-wheel drive or all-wheel drive. The V6 makes 365 horsepower and 376 pound-feet of torque, while the V8 makes 420 hp and 383 lb-ft.
• Safety package: Every version includes forward-collision warning, blind-spot monitoring, driver-attention warning, lane keeping assist, rear cross-traffic alert, and adaptive cruise control. Those features are standard regardless of engine or drivetrain.
• Infotainment: The G90 uses a 12.3-inch HD screen, Apple CarPlay, and Android Auto. The system is not wireless, and it relies on a console-mounted knob rather than a touchscreen.
• Fuel efficiency: The V6 returns 17 mpg city, 25 mpg highway, and 20 mpg combined with either drivetrain. The V8 gets 16 mpg city, 24 mpg highway, and 19 mpg combined with rear-wheel drive, or 15 mpg city, 23 mpg highway, and 18 mpg combined with all-wheel drive.

Which 2021 Genesis G90 trim should I buy?

The 2021 Genesis G90 is offered in 4 trim levels: 3.3-liter twin-turbo V6 with rear-wheel drive, 3.3-liter twin-turbo V6 with all-wheel drive, 5.0-liter V8 with rear-wheel drive, and 5.0-liter V8 with all-wheel drive.

Here's the short version:

• 3.3-liter twin-turbo V6 with rear-wheel drive: This is the best-value choice if you want the G90’s core luxury experience at the lowest starting price. You still get the full standard equipment set, strong power, and the best fuel economy in the lineup.
• 3.3-liter twin-turbo V6 with all-wheel drive: Choose this if you want the same value and standard features as the rear-drive V6, plus added traction for a $2,500 premium.
• 5.0-liter V8 with rear-wheel drive: Pick this if you want the stronger V8 character and are willing to pay more for it. It adds output, but the review still frames the V6 as the better all-around fit.
• 5.0-liter V8 with all-wheel drive: This is the most expensive setup and makes sense only if you specifically want the V8 with added traction.

Every version gets the same standard safety suite, so you do not need to move up a trim for driver-assistance coverage.

Is the 2021 Genesis G90 safe?

The 2021 Genesis G90 is an IIHS Top Safety Pick+. It also earns 10/10 safety score from our experts.

Every version includes forward-collision warning, blind-spot monitoring, driver-attention warning, lane keeping assist, rear cross-traffic alert, and adaptive cruise control. Those safety features are standard across the lineup, so you do not need to step up to a higher powertrain or drivetrain to get them.

Should I buy a 2021 Genesis G90 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:

• 24.5% of listings are priced as good or great deals.
• At 69.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 stands out for combining flagship luxury, strong value, and Top Safety Pick+ status.

Consider the 2020 if:

• The prior year is a strong value play with spacious luxury and a straightforward appeal.

The bottom line: You should lean toward the 2021 if you want the strongest mix of owner satisfaction, expert approval, and safety in this generation. If your priority is simply getting into a full-size luxury sedan for less, the 2020 can still make sense as a price-sensitive alternative.
