Latest Genesis engine complaints
Starter wiring burned and caused a small, localized fire in the engine compartment of the vehicle. Replacement of the starter assembly along with related engine wiring harness is necessary for vehicle operation. After mechanic review, it was determined the vehicle will catch fire upon attempt to start the vehicle. The vehicle was parked near our home when the internal burning and subsequent small fire started. The problem was reported to our nearest Hyundai dealership and the car was evaluated by the dealership to...

confirm the above. The car was inspected by Progressive insurance as well at the dealership and it was determined it was not included in TSB 24-01-057H recall for this VIN for the 2015 Hyundai Genesis. For this specific issue, there was zero indication this was a possibility.
Oil pressure switch in engine fails to accurately read oil pressure due to a lack of voltage, needing replacement. Causes driver to be unable to read proper oil pressure, leading to a possibility of fire through extreme overheating and friction-induced mechanical failure if the oil pressure is too low and unable to be read. The part has not been inspected by the manufacturer in any capacity, but it is a known issue with the Hyundai 3.8L V6 GDI engine. The oil pressure lamp will display at low RPMs and when at idle. A known fix it replacement of the sensor.
Oil light keep coming on when the car is stopped or at the light and turns off when it's running mechanic says it's an oil pressure switch which is a common problem with this car. I read a lot of complaints about this but Hyundai is not doing anything.
The contact owns a 2015 Hyundai Genesis. The contact stated that while stopped at a traffic light or while the vehicle was in drive, the vehicle failed to move, and the engine shut off unexpectedly. Several unknown warning lights were illuminated on the instrument panel. To restart the vehicle, the driver had to shift the gear selector into park and then press the start button. The vehicle was taken to a local dealer, but the dealer was unable to duplicate the failure or determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 120,000.
The oil pressure light illuminates at low RPMs and turns off under a load or higher RPMs. In checking Hyundai Genesis forums, this is a common failure/fouling of the oil pressure switch. Oil level is fine; it is the switch that fails, giving the owner a false sense of low oil and potential catastrophic engine damage. Unfortunately, the engine design requires a very expensive disassembly of the engine manifold and other parts to access and replace this small switch.
My car has previously been reported for having issues with electrical problems that I have had to fight the manufacturer to get repaired unsuccessfully.I am constantly experiencing and smelling burning in my dash when I crank the car. Car is no longer under warranty, so therefore, I cannot afford to continue to go in and report the same problem over and over again.My turn signal bulbs are constantly blowing, and I'm having to replace them at a rate that is not normal.I'm sure this is all related.
So there are TWO main points of concern on this vehicle, number 1 being the steering racks. Many other people have had the same issue as myself. Steering rack completely shut down about a year ago on the freeway, rendering my steering completely useless which was extremely dangerous. 8K repair bill that Hyundai will not acknowledge. Now that comes to my 2ND point, the oil pressure sensor switch. It's more common than the steering racks. Many owners are reporting it as low at 40-50K miles, yet there's an open recall...

in Korea for this exact problem. But the USA does not get any acknowledgment for it??? Yet another costly repair due to defective engineering. Might I add as well, the transmissions Prior to 2018 no matter if you've had them replaced, they end up failing and people get absolutely 0 help with them. It's ridiculous and these issue can eventually cost someone their life some day.
Was told by mechanic their was a possibility for fire with the starter mechanism.
Oil light appears when at a stop and goes off when accelerating. was told by mechanic this is a sensor problem common to my vehicle.
Engine oil light comes on and turns back off. Car has 97,000 miles and has regular oil changes.
The contact owns a 2015 Hyundai Genesis. The contact stated that while stopped at a stop light, the oil warning light illuminated on the instrument panel. The contact depressed the accelerator pedal, and the vehicle started to sputter and then stalled. The contact restarted the vehicle and drove the vehicle to an independent mechanic. The mechanic diagnosed the vehicle with a defective oil pressure sensor, and the contact was informed that the oil pressure sensor needed to be replaced. The manufacturer was notified of the failure and referred the contact to a local dealer for another diagnostic test. The vehicle was not repaired. The failure mileage was approximately 76,000.
The contact owns a 2015 Hyundai Genesis. The contact stated that while stopped at a red light, the vehicle started shaking with the check engine warning light illuminated. The contact stated that while depressing the accelerator pedal, the vehicle accelerated but failed to exceed 20 MPH. The vehicle was steered to the side of the road and shifted into park(P). The vehicle was restarted, but the failure persisted. The vehicle was taken to an independent mechanic, where a handheld diagnostic machine retrieved DTC:...

P2106, P0638, and P2110. The vehicle was taken to an independent mechanic, where it was diagnosed that the throttle body and the foot control throttle needed to be replaced. The contact was also advised by the mechanic that there may be an electrical system issue with the vehicle. The vehicle was not repaired, but the codes were reset. The contact took the vehicle to the residence and replaced the throttle body and the foot control throttle, but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 94,600.
While driving at approximately 70MPH on the highway, my 2014 Hyundai Tucson Limited suddenly locked up with no warning lights, no noise and no prior symptoms. The engine completely seized, causing immediate loss of power. I was barely able to coast off the highway exit to a final stop on the feeder shoulder, in a desolate area. The vehicle has always been properly maintained and is in excellent condition. Upon research, I learned that Hyundai has known of internal engine defects caused by metallic debris left...

from manufacturing since 2010, which can cause bearing failure and engine seizure. My Tucson's failure matches the same pattern described in Hyundai's Theta II engine recall and warranty extension campaigns. This sudden failure created an extremely dangerous situation at highway speed and possibility of injury while being stranded on an open road. Many owners, myself included, were never properly notified of the risks. I am filing this report because this incident represents a serious safety defect and potential recurrence among similar vehicles that may not yet be covered by recall. I respectfully request that the National Highway Traffic Safety Administration investigate this issue and ensure Hyundai expands its recall and warranty coverage to include affected 2014 Hyundai Tucson Limited vehicles exhibiting this defect that was well-known to the Hyundai Corporation. Date of Incident: October 23,2025 in Houston Texas. Vehicle towed to Hyundai dealer which diagnosed Engine Seized and currently awaiting Warranty Extension Approval (TXXC/TXXI)
Dear NHTSA, I am filing this complaint to formally report a serious vehicle safety hazard and to express concern over how Hyundai/Genesis has handled it. My 2016 Hyundai Genesis 3.8 AWD experienced a n engine compartment fire originating from the starter motor, which subsequently melted the engine wiring harness and surrounding components. This fire could have easily caused serious injury or death, as it occurred shortly after starting the vehicle. Fortunately, I was able t o shut the vehicle off and get t o safety...

before the flames spreadThe dealership and Genesis Customer Care opened a case (Case #41642221) but later informed me that this was "not related" to the existing Hyundai/Genesis recall involving the same starter and wiring harness fire risk. Their explanation was that my incident was merely a "coincidence" - despite the identical cause and symptoms described in the recall documentation. This reasoning is unacceptable, irresponsible, and ignores the fundamental issue: the fire originated from the starter, the same component already known t o have a fire-related defect. Dismissing a near-identical safety incident as unrelated poses a severe public safety concern and suggests Hyundai/Genesis may be avoiding accountability for additional affected vehicles outside the recall's VIN range. I believe this defect and the manufacturer's response warrant a n urgent NHTSA investigation into the scope of the existing recall and whether it should be expanded. This issue is not only mechanical but life-threatening, as an engine fire caused by electrical failure could easily occur while driving or in an occupied area. Please investigate this issue and ensure Hyundai/Genesis takes full responsibility for this defect before someone i s seriously injured or killed
