Should You Buy the 2023 Genesis G70?
This year holds a good reliability standing, but it is not the strongest pick. It rates below average against other 2023 sedans and lands in the middle of the eight scored G70 years. The 2022 rates about the same, with 25 complaints and 2 recalls. The 2024 rates better, but it has no complaints on file, which mostly reflects less time on the road.
Power loss is the problem to know. Owners describe limp mode on the highway, where the car will not go past roughly 50 mph even with the pedal floored. A restart often clears it, and dealers sometimes find no codes. Some owners tie it to the fuel pump and say repairs did not hold. Fogged headlight housings are the other repeat complaint. Federal recall records list one recall, in the fuel system, gasoline.
Ask for service records on any limp mode or stalling visits, and confirm the fuel system recall was completed. Look inside both headlights for moisture.
Compared to the 2024 Genesis G70, which scored 8 points higher. See also the 2022 Genesis G70 for an earlier comparison.

Used Buying Checklist
Key things to inspect or verify before purchasing a 2023 Genesis G70.
Accelerate hard onto a highway and confirm the car pulls cleanly, with no limp mode or capped speed.
Scan for stored codes, especially P0191 and P061B00, before buying.
Run the VIN for open recalls and ask for records of any fuel pump or software work.
Remote start the car, wait a few minutes, and check for a raw gasoline smell.
Inspect both headlights for fog or droplets inside, then test both turn signals for a "check turn signal" message.
Listen above 40 mph for a rear whine that rises in pitch with speed.
Watch for false slippery-road or uneven-pavement warnings while driving on dry, smooth pavement.
2023 Genesis G70 Common Problems by Component
17 owner complaints grouped by vehicle system.
POWER TRAIN
4 complaintsSudden power loss at highway speed is the main pattern. The car enters limp mode and will not accelerate past a certain speed, even with the pedal floored, and the dash may light up with warnings. Some drivers report high RPM with sluggish response. The problem comes and goes, and dealers often cannot reproduce it. Restarting usually brings back normal driving for a while. The risk is getting stuck in traffic, unable to merge or pass. A separate report describes a rear whine, like a wheel bearing, above about 40 mph that rises in pitch with speed.
ELECTRICAL SYSTEM
4 complaintsRandom limp mode and engine shutdowns lead these reports. Cars lose power at any speed and need a restart to recover. In one case the engine died in a parking lot and would not run for hours. Dealers sometimes find no error codes. Owners link the problem to the fuel pump and say repairs have not fixed it. Other reports describe a strong gasoline smell after remote start, which raises fire worries, and false slippery-road warnings on the dash. Several cases involve long dealer waits, back-ordered parts, or waiting on tech support.
EXTERIOR LIGHTING
3 complaintsMoisture and condensation inside the headlight housings is the main complaint. Once water gets in, the turn signal may stop flashing properly and a "check turn signal" message appears. Owners also report headlights going out, including at night, and fog forming in one lamp and then the other. Dealers have blamed cracked housings, but owners say the lenses are intact. Repairs are described as expensive, and some cars fog up again after being fixed.
ENGINE (2 complaints)
ENGINE
2 complaintsPower loss while accelerating onto the highway is the pattern here. The car hesitates, jerks, or stalls, then enters limp mode and will not go past roughly 50 mph, even with the pedal floored. Drivers end up in the slow lane with hazards on, unable to keep up with traffic. One report ties the fault to the fuel pump and fuel rail pressure, with code P0191 coming back after a dealer software update. Both complaints describe a problem that keeps returning after earlier service.
SERVICE BRAKES (1 complaints)
SERVICE BRAKES
1 complaintSafety-relatedI had heard a thumping noise in the front end when I would turn the vehicle. On the date of crash, there was a very loud pop noise, then loss of brakes and impact. Air bags deployed due to impact. Total loss.
