Should You Buy the 2020 Genesis G80?
Reliability is good for this model year. It is close to average among 2020 sedans and in the middle of the nine scored G80 years. This is the last year of the first generation. The 2019 rates worse, with 27 complaints against 10 here, and the 2021 rates about the same. Federal crash testing gave it 5 of 5 stars.
Tires are the clearest weak spot. Owners report sidewall holes, bubbles and blowouts, some after pothole hits, as early as about 11,000 miles. The tires named are Continental ProContact Rx. Others describe a dead battery that needs repeated jump starts, and rodents chewing soy-based wire coating, which sets off the check engine light. One brake report describes a crash at parking speed. Federal records list two recalls, and one is a park-outside fire-risk recall.
Ask for proof that both recalls were completed. Check the tire brand and the sidewalls, and ask about any battery or wiring repairs.
Compared to the 2021 Genesis G80, which scored the same. See also the 2019 Genesis G80 for an earlier comparison.

Used Buying Checklist
Key things to inspect or verify before purchasing a 2020 Genesis G80.
Run the AC for at least an hour on a hot day and confirm cold airflow never stops or turns warm.
Check around the turbo area for oil or coolant leaks and ask for records of any turbo oil feed pipe repair.
Test the brakes at parking-lot speed and confirm the car stops firmly without lurching forward.
Ask for service records of any ABS module work and confirm what the dealer actually replaced.
Have the battery load-tested and ask how often it has been replaced or jump-started.
Look under the hood for chewed wiring or rodent nests and scan for stored check engine codes.
Inspect every tire sidewall for bubbles, cuts, and wear around the edge.
Connect a phone by USB and listen for crackling or distorted audio.
2020 Genesis G80 Common Problems by Component
10 owner complaints grouped by vehicle system.
UNKNOWN OR OTHER
4 complaintsAir conditioning quits on hot days. After a stretch of driving, airflow stops or warm air comes out instead of cold, sometimes with an odd noise. Cabin heat can climb to dangerous levels. Dealers often cannot reproduce or diagnose the fault, and some decline warranty coverage. Several complaints say many other owners have the same problem. A separate report describes a leaking turbo oil feed pipe, raised as a fire risk, where the dealer repair left the oil leak unfixed and caused a new coolant leak.
SERVICE BRAKES
2 complaintsSafety-relatedBrakes fail to stop the car at parking speed in a crash report, and the car lurches forward into a fixed post. The other complaint concerns dealer work on the ABS module that consisted of swapping fuses for a higher amp rating, which the owner doubts fixes a defective module. With only 2 reports there is no broad pattern, but the crash report describes a loss of braking at low speed.
ELECTRICAL SYSTEM
2 complaintsThe battery goes dead and needs repeated jump starts, with battery replacements reported more than once in a year. Related symptoms include odd noises when a power source is attached, a car that runs hot with no warning lights, and crackling audio over the USB phone connection. A second pattern involves rodents chewing through the soy-based wire coating. That damage turns on the check engine light, can reach the starter wiring, and needs repeat repairs, in one case at about 12,000 miles.
TIRES (2 complaints)
TIRES
2 complaintsSidewalls fail, leading to flats and blowouts. Reports describe holes and bubbles in the sidewall, plus blowouts and cuts after pothole hits, sometimes on several tires at once. The tires named are Continental ProContact Rx in both the 245/40R19 front and 275/35R19 rear sizes. Failures show up early, including at about 11,000 miles. A sudden blowout while driving is a safety risk, and one report describes replacing both front tires after finding damage on each.
