2021 Genesis G80 Maintenance, Reliability and Warranty

Hyundai’s very own luxury brand has always been at the top of its game when it comes to ownership experience and reliability. It lets you experience the best without making your faith falter. 

As it continues to grow with its SUVs and Sedans, the trust of its buyers continues to grow alongside. Since you will be incurring low maintenance costs on the G80 as compared to the other luxury Sedans, our take is that you can safely put your trust into it. 

Reliability and Ownership Costs

Over the years, Genesis has been a dependable and reliable option for the gearheads, but one can’t ignore the fact that it’s comparatively a young manufacturer in the industry. For the same reason, the car has been overlooked by some of the users, but the car speaks for itself. Offering a comfortable driving experience and low maintenance cost with no major customer’s complaints, it’s not surprising that for the past two years, the Genesis G80 has not received any recalls. 

J.D. Power has not yet rated the 2020 Genesis G80, but the 2019 model has been rated 79/100, which is decent enough. The Genesis G80 also offers impressive warranty coverage and an excellent powertrain warranty.

On average, the 2020 Genesis G80 demands the cost of about $48,990. While people from New Jersey have to pay high for the car, people from Washington enjoy the lowest prices. 

Type of Expense



$46 (for the first year)

Tire change 

$560(for 18” wheels)





When we calculate the ownership costs of the new Genesis G80, you’ll have to fork out, on average, almost $62,716 within five years. This cost includes parameters such as depreciation, taxes and fees, insurance, maintenance, repairs, financing, fuel, etc.


The Genesis G80 offers a limited warranty of 5 years or 60,000 miles and a more extended powertrain warranty coverage of 10 years or 100,000 miles, which is quite remarkable in the automotive market. 

The Korean auto marque also offers 3 years or 36,000 miles of complimentary scheduled maintenance along with 5-years roadside assistance for unlimited miles on the G80. 



Limited Warranty

5 years/ 60,000 miles; whichever is earlier

Powertrain Warranty

10 years/ 100,000 miles; whichever is earlier

24-hour Roadside Assistance

5 years/ Unlimited miles; whichever is earlier

Standing in competition with Audi A6, Acura RLX, and Cadillac CT6, the G8 still provides the best-limited warranty coverage. Moreover, it offers the most extended powertrain warranty in the segment. 

Miles per Dollar

With a comparatively effective fuel economy and low-cost maintenance, the Genesis G80 is a pocket-friendly investment for a luxury Sedan. You spend approximately $3,250 more on fuel costs over five years compared to the average new vehicle. So for each mile the car runs, you have to pay roughly $0.83. 

2021 Genesis G80 Buying Advice

We would recommend the 2.5T Standard trim level as it comes equipped with almost every tech and feature that a luxury Sedan is ought to offer. It is integrated with the leading safety technology, highly refined luxury interior appointments, and driver-focused features; and all of it at such a budget-friendly price. 

Is buying a used Genesis G80 a good idea?

Though the Genesis G80 is not very popular amongst the luxury Sedan users as it is entirely new for the segment. However, with Hyundai’s backing, its reliability has been increased. Besides, its low-cost maintenance makes Genesis G80 a good investment. It also offers an excellent powertrain warranty coverage of 10 years or 100,000 miles, which makes it more reliable even if you are investing in a used car. 

We would recommend that you go for the 2019 Genesis G80 3.3T sport model because it offers a power-packed engine, which is unlikely to turn weary for many years along with utmost luxury and sporty drive experience. 

2021 Genesis G80 Engine and Performance


The 2021 Genesis G80, offers two engine choices for the users to choose from. There is a 2.5L turbocharged Inline-4 engine and 3.5L twin-turbo V6 engines on offer to choose from. However, the V8 mill, which was available until the 2020 year model is no longer an available option in the new Genesis. 

2021 Genesis G80 Engine

The 2.5T Standard, 2.5T Advanced, and 2.5T Prestige Trim levels come equipped with a 2.5L twin-turbocharged Inline-4 engine generating a power output of 300 hp @ 5800 rpm and torque output of 311 lb-ft @ 1,650 rpm. On the other hand, the 3.5T Standard and 3.5 Prestige Trim levels are powered with a 3.5L twin-turbo V6 engine with a power output of 375hp @ 5800rpm and torque output of 391 lb-ft @ 1300 rpm.

Both the engines are mated with an 8-speed automatic transmission coupled with either a rear-wheel-drivetrain (RWD) or an optional all-wheel-drivetrain (AWD) system.

285 lb-ft @ 5,300 rpm

273 lb-ft @1,600 rpm

With the most potent engine figures, the Cadillac CT6 is sitting on the top of the pack in terms of power output. The Acura RLX bags second place in the same category. Though with the 2.5L Inline-4 engine, the 2021 Genesis G80 is in third place. However, if one is opting for the 3.5T Trim levels, then the Genesis is unbeatable.

2021 Genesis G80 Acceleration And Braking Performance

The 2021 Genesis G80 is exceptionally fast when you test its outright acceleration. It takes only 5 seconds for it to reach 60mph from its steady position. And the quarter-mile timings for the 2021 Genesis G80 is 12.9 seconds. It delivers a decent top speed of 149 mph.

Having a more aerodynamic design than its predecessor, the 2021 Genesis G80 manages to beat the 2020 Audi A6 and tops the chart with its impressive outright acceleration. The new Genesis also offers the most effective braking efficiency against the competition.

2021 Genesis G80 Fuel Economy


When it comes to fuel efficiency, the new Genesis G80 performs quite well and delivers an estimated EPA of 19/28/20 mpg in the city/highway/combined. The new 2021 Genesis G80 also offers a generous fuel tank capacity of 20.3 gallons and delivers a handsome combined cruising range of 406 miles.

The 2020 Audi A6 is a clear winner in terms of fuel efficiency. With its smaller engine, the car manages to deliver an outstanding fuel economy of 32mpg on the highway. On the contrary, even with the highest fuel tank capacity, the 2021 Genesis G80 fails to perform well on longer runs.

2021 Genesis G80 Interior


Korean architectonics slurped in opulence; the 2021 Genesis G80 captures the eye with its roomy and luxury-driven interiors. Its interiors are loaded with tech and give out a feel of an austere layout. 

The 2021 model is an excellent resurrection of its 2020 model. Furnished with supreme open-pore wood and metal trim with leather finishing and ambient lighting, the cabin of the car emanates beauty everywhere on the inside. The 2021 model, no doubt, looks more elite!

​  2021 Genesis G80 Front Seat

As you sit in the car, the first thing you’ll notice would be better visibility which you get with the thin A-pillar, lowering the dashboard’s height and altered rearview mirror dimensions. The dashboard is split into the upper panoramic area with center touchscreen and lower house controls that comprise the vehicle’s systems.

Rear Row (Headroom/Shoulder Room/Legroom; inches)





While the 2020 Acura RLX offers the most shoulder room space in its first row, the 2020 Cadillac CT6 provides the best legroom space in its second row. Other than that, the 2021 Genesis G80 is not ready to compromise with its comfortable seating and delivers the roomiest interior space for its occupants in both of its first and second rows.

How’s the 2021 Genesis G80’s infotainment system?

The 2021 Genesis G80 features a massive 14.5-inch touchscreen infotainment system at the top center of the dashboard along with a 12.3-inch 3D digital instrument cluster. The central touchscreen display can be controlled by a circular controller knob situated at the center console. It can also be manipulated via buttons on the steering wheel as well as can be operated with voice commands. 

​  2021 Genesis G80 Dashboard

As standard, the 2021 Genesis G80’s infotainment system features Genesis connected services, navigation, steering wheel mounted audio/cruise/phone controls, wireless Apple CarPlay & Android Auto compatibility, AM/FM/XM Radio/HD Radio and over the air updates. 

There’s no shortage of entertainment in the G80. It comes equipped with Premium audio with 12-speakers which can be upgraded to a Lexicon premium 21-speaker audio system by opting for the advanced package. It’s rumored that the Genesis G80’s infotainment is going to be similar to the revamped 2021 G90! 

2021 Genesis G80 Exterior


If Genesis’ stalwart structure doesn’t convince you of its muscularity, its crest grille and quad lamps ornamented front fascia will surely do. When you examine its exteriors, you notice athleticism and elegance sitting beside each other on the balancing machine! 

​  2021 Genesis G80 Third Quarter View

The car looks familiar but it’s a revamped version of the 2020 model. The rear has a sloping decklid covered with LED taillamps and fender side lamps. Besides, the chrome trim across the exteriors heightens the visual motion. The Genesis G80’s chrome-laden shield grille makes the Sedan look different.

Being the bulkiest, the 2021 Genesis G80 shares its dimensions with its outgoing model. The new G80 offers the highest ground clearance of 5.3 inches, and the new rear-wheel-drive system has lowered the body with its center of gravity and it's more extensive body which now provides a more stable drive.

2021 Genesis G80 Safety


The new Genesis G80 has not been crash-tested by the NHTSA and IIHS yet. But IIHS has given a “Good” rating to the 2020 Genesis G80 in all the parameters, and NHTSA has given “5-star ratings” to it. IIHS also rated the G80 with the “Top Safety Pick+” rating.

2021 Genesis G80 Competition


2021 Genesis G80 vs 2020 Acura RLX

The 2020 Acura RLX boasts a powerful engine as compared to the 2021 Genesis G80. But if we compare its engine with Genesis’ 3.5T Standard and Prestige trim levels, then they’d surely take Genesis ahead.

2020 Acura RLX

Acceleration-wise, Genesis beats the Acura. But in top speed and fuel economy, Acura surpasses it. 

2021 Genesis G80 vs 2020 Cadillac CT6

The Cadillac again beats Genesis in terms of engine and performance, and yet again if we compare it with the 3.5T Standard and Prestige trims, Genesis would undoubtedly win.

2020 Cadillac CT6

When compared based on braking performance and fuel tank capacity, Genesis has the upper hand. Both offer similar fuel economy!

2021 Genesis G80 vs 2020 Audi A6

Genesis comes out as a more powerful car with a better engine in comparison with Audi A6. Even then, Audi gives a stiff competition to Genesis in terms of acceleration, top speed, and quarter-mile timings; perhaps because of its less curb weight.

2020 Audi A6

Plus, Audi A6 has surprisingly better fuel efficiency and a better cruising range even after having a small fuel tank capacity. 

2021 Genesis G80 Final Verdict

Amidst a line of stellar luxury Sedans, the Genesis G80 comes out like a solitaire! It’s a comparatively new brand which is why it doesn’t come with a long history of glory, but it speaks out the brilliance in performance and comfort. 

The 2021 Genesis G80 can give a fierce competition to the leading Sedans in the market with its feature-packed interiors, reduced curb weight, and a new powertrain. You can let the jewel in the crown shine bright and try the Genesis G80!
