Generation & Refresh (US)
2021 is the first model year of the Second generation (RG3).
- First-year models may have unresolved issues from the new design.
- Redesigned for the 2021 model year.
- Refreshed in 2024.
- 2nd generation G80 (US).
What this means for buyers
First-year models carry more risk — early production issues are common. Consider waiting for the second year if reliability is a priority.

Should You Buy the 2021 Genesis G80?
Reliability is good for this year, and it sits close to average among 2021 sedans. Inside the G80's own history it lands in the middle of nine scored years. The 2020 and 2022 models rate about the same, so no neighboring year clearly beats it.
The tires are the main worry. Owners describe sidewalls that fail suddenly, with no warning, on the 20-inch staggered setup. One owner reports three sidewall failures in the first 25,000 miles. One of the three tire filings actually involves a GV80, so the true count for this car is lower. Electrical faults come next: power windows that work only intermittently, and in one report a total loss of gauges and driver aids. Two owners also describe clicking from the brake pedal, starting around 26,377 miles in one case, with no loss of braking. Federal records list four recalls, three for the gasoline fuel system and one for seat belts.
Ask the seller for proof that every recall was completed. Check the tire brand and age, and look for any past sidewall damage or replacements.
Compared to the 2022 Genesis G80, which scored the same. See also the 2020 Genesis G80 for an earlier comparison.

Used Buying Checklist
Key things to inspect or verify before purchasing a 2021 Genesis G80.
Inspect inner and outer sidewalls on all four tires for bulges, cuts, or cracks.
Check which tire sizes are fitted and ask how many tires have been replaced and why.
Confirm the spare is present, inflated, and usable before buying.
Operate every window from every switch several times, then test the memory seat buttons.
Ask for service records showing any window, door switch, or wiring harness repairs and whether the problem returned.
Watch the gauges and warning lights on a long drive for flickering, dead displays, or a sudden wall of warnings.
Stop in Drive, press the brake pedal repeatedly, and listen and feel for clicking or tapping.
2021 Genesis G80 Common Problems by Component
9 owner complaints grouped by vehicle system.
TIRES
3 complaintsSidewalls fail suddenly, with no warning before the tire goes flat or blows out. Reports center on the 20-inch staggered setup, 245/40R20 front and 275/35R20 rear, with more than one tire failing on the same car. One account describes three sidewall failures within the first 25,000 miles. Another describes two tires failing within about a mile, one exploding while driving on the spare. Owners stress the danger of a blowout at highway speed. One of the 3 filings actually concerns a GV80 on different tires, not this car.
ELECTRICAL SYSTEM
2 complaintsPower windows stop responding to their switches and work only intermittently, sometimes alongside a memory seat that ignores button presses. A dealer harness replacement under warranty did not end the problem in one report. A more serious failure has every warning light come on while the gauges go dead. The speedometer, turn signals, steering and driving assists, collision avoidance, cameras, infotainment, windows, and trunk release all stop working, with power steering, brake, and ABS warnings displayed. Losing signals and safety systems while driving raises crash risk.
SERVICE BRAKES
2 complaintsPressing the brake pedal produces a clicking, ratcheting, or tapping sound, and sometimes a tapping feel through the pedal. It happens with the car stopped in Drive and while moving, and is audible in the cabin. One report places the source under the hood and says the noise is present on every press, beginning around 26,377 miles. Neither filing describes a loss of braking or a crash. The complaints focus on the noise and pedal feel rather than reduced stopping power.
UNKNOWN OR OTHER (1 complaints)
UNKNOWN OR OTHER
1 complaintThe G80 is equipped with a bluetooth system that should read incoming text messages while in drive. (see https://www.youtube.com/watch?v=cxfPQ37jJbI&t=6s) Instead, after I select "Listen" the car tells me "unavailable while Driving." When I close this system message, the display shows the first several words of the text message - allowing me to read the message while in Drive. This is unsafe. My vehicle is not the only one experiencing this problem - see https://genesisowners.com/genesis-forum/threads/voice-text.37457/ for other reports and more details. I have contacted Genesis USA several times with no luck. I have returned the car for service multiple times with no resolution.
POWER TRAIN (1 complaints)
POWER TRAIN
1 complaintThe contact owns a 2021 Genesis G80. The contact stated while driving 30-40 mph on two separate occasions, the transmission disengaged, and the vehicle stalled and restarted without warning. The local dealer was not contacted. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The failure mileage was 29,034.
