What 2023 Genesis G80 owners say
Most recent owner complaints, unedited.
Description of Incident: The car was sold with a passenger-front Dunlop tire that suffered a critical structural failure where the tread rubber completely wore away, leaving the internal metal cords and plies exposed (visual evidence attached). I was unknowingly operating the vehicle in this hazardous condition for 136 miles of highway and local driving until the defect was fully identified on February 14th. Component Availability: The tire was removed from the vehicle on February 14th by an independent service center during the emergency purchase of four new tires. While the physical tire was left for disposal at the service center, high-resolution photographs of the failure are available and attached to this report for inspection. Safety Risk: The vehicle was sold in an unsafe and illegal condition (IL Vehicle Code 625 ILCS 5/12-405). The exposed structural metal plies created an imminent risk of a high-speed blowout or catastrophic tread separation, endangering both the occupants of my vehicle and other motorists. Confirmation/Inspection: The problem was confirmed by a certified technician at an independent service center on February 14th, who identified the tire as unfit for service. The selling dealer (Jidd Motors) was notified of a defect on February 6th but refused to replace the tire. This incident has also been reported to the Illinois Attorney General and the Illinois Secretary of State Police (Dealer Operations). Warning Symptoms: There were no warning lamps, TPMS messages, or symptoms prior to the physical discovery of the exposed metal. The tire maintained air pressure despite the severe structural compromise.

My TWO WEEK OLD 2023 Genesis G80, which has less than 1000 miles on it, lost all motive power (i.e. power to the engine) after driving for approximately four hours. We were sitting in stop-and-go-traffic on the George Washington Bridge in New York, with the engine off (because of the vehicle's auto-off function). When the car ahead of us moved, I lifted my foot off the brake pedal, pressed the gas, and the engine immediately failed to respond, sputtered, and stopped. After about a minute, we were able to restart the engine and continue driving. We drove for another approximately 1.5 hours, including a short rest stop. Then, while traveling at highway speed of ~75 MPH in the left passing lane of Interstate 84, the engine again lost all motive power. When the accelerator was depressed, there was no response. I was able to (narrowly) safely maneuver (drift) my car into the breakdown lane, and when the car finally stopped, the engine stopped entirely (it had been sputtering while coasting). After a few minutes, I was again able to get the car re-started, and we were able to drive another five minutes, before the car again lost all power, forcing us to drift off the interstate into the breakdown lane, near the beginning of an off ramp. I saw that there was a Hyundai dealer approximately a mile off the ramp, and so tried to reach the dealership. The car lost all engine power multiple time, just trying to reach that dealership. In the parking lot, we were unable to even start the engine any time in the next three hours. Most concerning, after having the car towed to a Genesis dealer, the dealership reports that the car showed NO FAULTS OR ERRORS, and they are completely in the dark as to why the car lost all power, both while stopped, and at highway speeds, and failed over and over. The lack of any reported faults or errors is both baffling and extremely worrisome. The dealer "hopes" but is unsure, that replacing the GDI fuel pump will resolve the issue.
