Electrical system

28 reports1 related recall
“My 2017 Genesis G90 received Safety Recall 018G (NHTSA 24V-107) on December 31, 2024, addressing a starter-solenoid electrical short/fire risk. Around June 7, 2026, I noticed an unusual odor and found the engine-room junction/fuse box extremely hot, with visible heat damage. An independent shop documented melted plastic near the starter relay/junction box, cleaned damaged material, replaced a 200A fuse, and reinstalled the relay kit. It recommended replacing the junction box, which was not done. Around August 7-8, 2026, warning indicators and steering-related problems occurred. The vehicle was towed to Genesis Dublin August 10. Inspection identified substantial thermal damage to the junction box and wiring. The vehicle remains unrepaired at the dealership, with damaged components believed available for inspection. The vehicle was also evaluated for an insurance claim. At a September 24 walkthrough, dealership personnel confirmed that the damaged junction-box/alternator connection area overlaps the area where alternator-related connections were handled under Recall 018G (Step 6, TSB 24-01-059HG). They discussed possible alternator overcharging but said damaged…”

Engine

22 reports
“This vehicle experienced an engine overheating failure while driving, five days after a cooling-system repair (radiator hoses, valve cover gaskets, spark plugs) had been completed at the dealership. The dashboard displayed an explicit "Engine has overheated" warning, and the vehicle could not continue to be driven. The vehicle was returned to the dealership. Per their own written statement, there were "no signs of engine damage related to the overheating concern" at that time. The vehicle's own mileage record shows it did not leave the dealership's lot for nearly a month afterward, despite a written claim that the shop foreman had personally test driven it before release. After that release, a fractured metal bracket was found in the engine compartment near the serpentine belt, along with multiple additional loose, missing, or unseated fasteners throughout the engine bay. The dealership's technician stated he had no reason to have inspected that area. The cause of the fracture and the discrepancy with the technician's account have not been resolved. Separately, the vehicle's Lane Keeping Assistance/Lane Departure Warning system has been non-functional, was…”

Power train

12 reports
“My 2017 Genesis G80 3.8L, VIN [XXX], has approximately 43,840 miles and intermittently slips or shifts improperly between approximately third and fifth gears while driving and causes harsh jolts forward. Jenkins Genesis confirmed the condition, stated that the transmission was slipping from the 3–5 clutch area, and recommended complete transmission replacement. The malfunction is unpredictable and creates a risk of sudden loss or interruption of propulsion while merging, crossing an intersection, changing lanes or driving at highway speed. A driver may press the accelerator but not receive the expected forward power. A [XXX] infant is regularly transported in the vehicle. The vehicle also has a faulty right-front ABS wheel-speed sensor, a passenger seat-belt safety-system communication fault, and intermittent electrical or sensor warnings. Genesis TSB 21-AT-010HG-1 applies specifically to the 2017 G80 and addresses shift flare or harsh shifting during the 2–3, 3–4 and 4–5 shifts. It requires transmission-solenoid, wiring-harness and fluid inspection procedures. TSB 19-AT-014HG also addresses harsh or delayed shifting in 2017–2018 G80 vehicles and provides…”

Steering

8 reports1 crash
“As I am driving and I make a turn, the wheel actually locks and I cannot steer. It was very frightening. At first I thought it was the lane change device, but I made sure that was off, and it happened twice more. I had the car towed to the Napleton Hyundai dealership in Lake park, FL and they said the entire steering column needs to be replaced. They quoted over $10,000 for the repair. THe car is a 2017 Genesis G80 with 23,000 original miles. THere were no warning lamps or other symptoms.”

Service brakes

7 reports2 crashes
“November 2, 2025 at 12:19 PM, I received a call from the owner, Jose, who accused me of “assault” against his employee Toni—despite the fact that I have never been physically near Toni. I’ve only been calling to follow up on the unresolved safety issues: no fluids, bad brakes (which they claimed to have repaired), and rear tires with no tread at all. When they repaired the brakes, I would have gladly purchased new tires had I been informed. On November 3rd at 8:23 PM, I found myself stranded on the side of the highway once again—this time due to exposed tread and a large bubble on the tire. It’s deeply troubling that a vehicle was sold in such unsafe condition. This raises serious questions about the seller’s standards and accountability. November 5, 2023 at 12:33pm third flat tire and the spare blew out into pieces after one day. On November 8, 2025 at 11:30am, the second bald tire completely blew out while I was driving on 595. This was not just an inconvenience—it was a life‑threatening situation. I could have been killed. The fact that this dealership allowed such unsafe tires to be sold or installed shows a complete disregard for customer safety.This is…”
