vehicle still would not start because the starter relay circuit was failing. Instead of repairing or replacing the defective recall relay assembly, the dealership wired an unauthorized aftermarket Relay Bypass Switch Kit (Part #54762610) directly into the under-hood recall relay assembly. Shortly after retrieving the vehicle and installing a new battery, the under-hood relay assembly and bypass switch caught fire, melting the components and leaving the vehicle inoperable. Both the dealership and Genesis Motor America have failed to remediate the fire damage or honor the safety recall repair. I have both service invoices and photographs of the burned components available for NHTSA investigators. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
This complaint is filed regarding an under-hood thermal fire incident and unauthorized modification involving a federally mandated safety recall for a 2018 Genesis G80 (VIN: [[redacted]]). To resolve a starting issue, technicians at Van Hyundai in [[redacted]], bypassed the standard ignition circuit and installed an un-fused manual starter bypass switch kit. This bypass directly conflicted with active NHTSA Safety Recall Campaign 24V107000, which requires a specific fused relay kit (Part 91950-DH15KQQH) to...

prevent engine fires. This unauthorized, un-fused modification caused a severe electrical short and a subsequent thermal fire incident under the hood. The fire physically melted and destroyed the recall component and adjacent wiring infrastructure. The dealership and corporate office are now refusing to fix the fire damage they caused unless I pay out of pocket. I request an immediate federal investigation into this hazardous repair practice that completely compromised a critical safety recall remedy.

Failing oil pressure sensor which "blinds" the driver of the engines true oil levels. It occasionally causes the car to go into "limp" mode or stall which could cause unnecessary and unreasonable traffic safety hazards. This is a well known and documented critical safety defect by Genesis as they've already executed a recall for the issue in their home country / market of South Korea.
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.
When you press on the gas accelerator- the car only moves at a few miles per hour. This is intermittent but makes the car undriveable and very dangerous to drive in traffic. The throttle body was replaced but now geneis says it is another electrical issue and the car needs a new harness- but gensis no longer makes this part (the harness) so genesis even under my warranty cannot fix the car genesis says it is a harness issue and they don't have and cannot get the part- hence they cannot fix the car
The contact owns a 2018 Genesis G80. The contact stated that the Check Oil and Low Oil warning light illuminated while the vehicle was idling. The warning lights turned off while driving. The vehicle was not taken to the dealer or an independent mechanic to be repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 72,200.
My oil light kept flashing on while driving until I come to complete stop. Had to take it to Genesis dealership in [[redacted]] Ms. They did a check on my vehicle and found the problem. I had to pay to replace these issues the sender assy-oil pressure & the harness-op sensor. The total bill was $1,012.14.

Car less than 1 month old with approx 500 miles caught fire from the engine and was totaled. Nearly took the driver and house with it.
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.

Component: Engine / Turbocharger / Oil Line / Fire Risk Vehicle Problem: For the past five months, my oil light has been coming on and off sporadically (not flickering), even though mechanics and oil shops said there was no issue. A few days ago, the car started smoking out of nowhere, though it wasn't overheating and there were no visible signs of leakage. I took it to the shop, and they diagnosed a turbocharger oil supply pipe leak that is severe and poses a fire risk. I am in a new city with no support system...

and have a baby. Multiple car dealerships have refused to fix my vehicle, even though I have been informed this part is under recall. I have tried calling and visiting, and no one will help. This is a safety concern, especially since the vehicle is at risk of catching fire while driving.
Engine while driving inadvertently stalls and vehicle shuts off. Does not matter what the conditions are. Have to place vehicle back in park and completely shut down vehicle to restart. It first starts by engine slowing down and then engine speeding up and ultimately stopping. When placed in park vehicle lungs forward slightly and front sensor tends to go off in warning without a vehicle in front of
I took my car in to have a recall repair completed. A relay kit was added to the engine compartment and my car has not operated the same since. When I start my car now it idles rough and is making noises that it wasn't making before. When I accelerate my car stalls and is sluggish. Also when I accelerate my car stalls and speeds up uncontrollably, which is a concern for safety. I've contacted the dealership where this repair was completed and told them all the issues I've been having since the repair was completed....

They keep stating that there is nothing wrong. I've spoken with Customer Relations and the Regional Manger only to get no assistance. I'm concerned about my safety and how this repair will affect my extended warranty because my engine has been altered. I wasn't having any of these issues until this repair was completed and the dealership seems not to care or taking this seriously. The Regional Manager didn't call me back until maybe a week or so after I kept constantly calling and advising that I was going to go to the news and get a lawyer. This issue has not been resolved.
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.
