   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.

   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 twice described by the dealership's technician as "working," and both times disproven by independent testing showing the system displaying "system off." The vehicle has also been producing smoke while driving and idling, consistent with a fluid leak burning off a hot engine component, accompanied by a worsening chemical/exhaust-like odor in the cabin, not yet diagnosed. This is reported given the overheating history, the undiagnosed cabin odor with possible carbon monoxide exposure risk, and engine-bay damage discovered following dealership service, in case relevant to safety monitoring of this repair pattern.

   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 electronic shift-data testing. The written repair estimate does not establish whether all applicable TSB diagnostic procedures were completed. The model also has electrical recall history, including NHTSA recalls 24V-107 and 21V-161. I am not claiming the recalls caused the transmission failure, but the concurrent transmission, ABS, seat-belt and electrical faults warrant investigation. I request that NHTSA examine similar G80 complaints involving slipping, shift flare, delayed shifting and loss of propulsion.

   While driving the engine simply stops and won't restart. When this happens, the key fob won't lock the car or unlock the trunk. The trunk opening button won't open the trunk. It just flashes the parking light and gives a sound.

   At 63,230 miles the engine oil pressure light would illuminate on my 2017 Genesis G80. I took it to the dealer and the technician found the oil pressure switch on my car went bad and in the words of the mechanic was leaking internally. This is a known issue by Genesis/Hyundai as they are performing repairs in Korea (where this vehicle is built and assembled) for this very problem. But in America they are refusing to honor the warranty which under powertrain is valid for 10 years/100,000 miles. Proper function of the engine is clearly a part of the powertrain. The warranty further goes on to state that under engine, "gaskets and seals" are covered. The repairs I had to have performed at great expense for a failed oil pressure switch seemed clear to me under the warranty. Not only a known issue and covered where the car is made, but they seem to know they have a huge issue based on Genesis Forums and their complaints the numbers are large; they don't want to have to make it right for the owners.

    Subject: Safety Concern Regarding 2017 Genesis G80 Dear NHTSA, I am writing to report an ongoing issue with my 2017 Genesis G80. While driving, I have experienced a significant safety concern related to the vehicle's acceleration. Specifically, when accelerating at various speeds, the vehicle begins to jerk abruptly and violently, causing a potentially dangerous situation on the road. After seeking advice, I was informed that the problem might be related to the engine malfunctioning or failing. I am deeply concerned about the safety risks this poses, both for myself and others on the road. I would greatly appreciate any guidance or investigation into this matter to ensure the issue is addressed promptly. Thank you for your attention to this serious safety concern. Sincerely,

    The hyundai genesis and the genesis G80 have an oil pressure sensor defect. Practically, everyone i know with a genesis, in particular the 3.8 L engine, has this issue. The oil pressure sensor illuminates even though the engine oil level is fine and this issue can occur at any time regardless of mileage. I'd be surprised if this issue has not been reported to you all.

    I want to file a complaint regarding the recall issued for my car. I am concerned that Genesis has not issued a resolution at all and suggests parking the car. If it's unsafe and could ignite itself on fire, a remedy should be issued immediately. Offer us a different model and year or fix the issue. This is people's lives at stake.
