Oil pressure light started to come on at idle, goes away while driving.. heard this has been and issue and even the dealership knows about it.. there is also a recall in Korea for the same exact thing for the same exact cars but no recall in the usa..please make this a recall it is not safe nor should this be over looked
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.
My oil light kept flashing on while driving until I come to complete stop. Had to take it to Genesis dealership in [XXX] 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.

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.
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.
Intermittent low oil pressure light (at low RPM) TSB issued for Korean customers, not for US Customers.
I am the original owner and when my vehicle reached approximately 65,000 miles just past the warranty the oil service light would come on sometimes then go out. i have had documented oil changes from my dealer approximately every 3500 miles. Everything seems to be normal in the car and the oil level checked on a regular basis is always ok. When the RPM rises above 2000 rpm the oil service light goes out and returns when the rpm is lower. After visiting a Genesis vehicle Forum web site which i subscribe to i discovered that it's a common problem many vehicles owners of the Genesis model particularly the G80. I am told that the remedy is costly due the need to remove the entire vehicle's intake manifold to get to the device and replace it which is causing the problem. This appears to be a factory device part failure as was explained to me and it may or may not fail within or after the warranty expires. Also whenever it rains my ABS warning light comes stating that the system is inoperable. Never comes on in dry weather.
oil Pressure sending unit I tried to get it fixed at a local shop but they refused because it was too tough a job for their skill level, I was confused about s until I saw a video showing the sensor being under the manifold and between cylinders and someone had broken their timing cover while replacing. Driving with the faulty sensor could lead to not knowing if an oil pump has failed causing engine failure upon driving. problem has been confirmed have not taken to dealer for inspection, mostly because I have not had the money to pay for the job started around 68k miles, oil light went on.
