The version owners recommend
The 5.0 V8 is the consensus pick among owners. Multiple owners describe the Tau V8 as "dead reliable," "gloriously powerful," and "silky smooth," with one owner reporting over 200,000 miles without trouble. The 3.3T is considered a good engine but "a tad underwhelming for the big G90." Owners also note the 5.0 uses about 9 quarts of oil per change, adding roughly $30 per service.
Competitors to consider
Owners compare it most often with the Lexus LS, BMW 5 Series (including M5), Mercedes E-Class, Audi A5 and Porsche Panamera.

Overall sentiment
Owners generally view the G90 as an exceptional value on the used market, praising its luxury features, ride comfort, and the reliability of both the 3.3T V6 and 5.0 V8 engines. The dominant sentiment is that the car offers S-Class-level luxury at a fraction of the price, though owners consistently warn about expensive parts, complex electronics, and the importance of a prepurchase inspection. The 5.0 V8 is repeatedly described as "dead reliable" and "gloriously powerful," while the 3.3T is considered solid but slightly underwhelming in the heavy G90. Some owners express hesitation about long-term ownership due to the sheer number of sensors and electromechanical components that could fail without warranty coverage.
Positioning vs competitors
Owners position the G90 as a direct competitor to the S-Class, 7 Series, A8, and Lexus LS, but at roughly half the price. Compared to the BMW 540i and Mercedes E450, the G90 is described as a class above in luxury and quietness. Against the Audi A5, owners note the G90 is a nicer car overall and more affordable to maintain. The Lexus LS is acknowledged as the reliability king, but owners point out that a comparable LS460 would cost roughly twice as much. The Kia K900 is seen as a slightly cheaper alternative with similar depreciation, though the G90 is considered better looking. The Panamera and R8 comparisons are from a separate thread about the BMW M5 G90 (a different vehicle), and those discussions note the Panamera is more special and better on twisting roads while the M5 is more practical and faster in a straight line.
Recommended configurations
Owners recommend the 2017 or 2018 G90 with the 5.0 V8. The 2018 model year is preferred for its improved infotainment, as the pre-2017 system is described as lacking. One owner specifically recommends buying a Genesis that is at least 3 years old to avoid the steep initial depreciation. The 3.3T is acceptable for those prioritizing fuel economy, with one owner reporting 22.5 mpg daily driving, but the V8 is the enthusiast choice.
General recommendations
Owners strongly recommend a prepurchase inspection before buying any G90, given the complex electronics and expensive parts. Multiple owners emphasize checking service history over raw mileage, noting that 105,000 miles is not excessive if properly maintained. The three-owner history on some cars is flagged as a potential concern. Owners advise budgeting for a suspension refresh before 150,000 miles and listening for creaks and rattles during a test drive. Those who cannot do their own maintenance should be prepared for luxury-level repair costs. One owner warns that dealership experiences can vary significantly, with some Hyundai dealers not knowing how to treat luxury buyers. The fire recall on certain models is mentioned as a deciding factor for one owner with young children.
Remarks
Owners note that the G90 is a car meant to be driven in the back seat, with one owner describing it as "more of a car where the owner would sit in the back." The G80 is suggested as a more driver-focused alternative that delivers 90% of the experience for less money. One owner reports that the 3.3T can run on 87 octane fuel, though the original sticker specifies premium. The 2017 model year was the first for the 3.3T engine, which gives some owners pause, though no specific issues with that engine are reported.
