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.

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.

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 the federal safety agency 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
