Hyundai Genesis overheating problems

Filed Apr 21, 2026 · Engine · MD

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.

I was driving the car, and without warning, it just said engine overheating and shut off. If I had pulled out in front of someone, I could easily have gotten killed. There was no prior indication of anything wrong. Just riding down the road and it just shut off for no reason and would not restart. Towed it to the dealership and they told me that I need a new electronic control module and quoted a price of $4,000. That is freaking outrageous for something that should never have gone wrong in this car. I researched online and there are multiple Hyundai Genesis sedan owners have had a problem with the electronic control module going out for no reason. This is something Hyundai should be held accountable for as it is a major safety hazard. For your car to just shut off for no reason while driving it, is extremely dangerous and life-threatening.

Daytime running lights(drl) and front turn signal bulbs burn out very frequently due to the fact they are the same filament in the bulb even though they require a dual filament bulb. The wiring harnesses also show significant signs of overheating. This is a very widely-known issue in the online forums for this car and is a completely unsafe issue. The drivers side bulb is easy to replace, but the passenger side is not. I have replaced the drivers side 3 times and the passenger side 2 times in the last year. Between bulbs and mechanic fees for the passenger side, I have spent $200-$300 in the last year maintain this unsafe problem.

I've had to replace the turn signal bulbs several times (3 times so far). The 2015 model uses one light to function as both the daytime running light and also as the turn signal. It looks to me like they overheat and it was probably a bad design in my opinion. I feel like hyundai needs to strongly consider a recall to rectify this ongoing problem. I don't ever remember having to replace a turn signal on any of the vehicles I've ever owned and it seems this will be an ongoing problem. It creates a bit of a safety issue too - being without a front turn signal when this happens. I put march 16 below as that was the most recent occurrence.

Takata recall" 4. The airbag light will not go off. Atlanta police stated I not drive the car and to report it. My family lives could be in danger. No mechanic wanted to touch it. I would very much like to this these items repaired, especially the airbag signal/light. I don't know if it will go off or not but I need this done before anything else. I will upload the picture via email. System issues. I purchased a used 2009 genesis sedan in september of 2015. We have noticed that several unusual issues have surfaced since the purchase. I was never notified of any of the recalls or potential issues below. 1. The console for the seater heaters are melted or got overheated and is damaged. 2. When the brakes need updated they are very dry (per the repairman) recall - 114. 3. Window shield wiper seems to have a defect.
