Genesis
G80

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.

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 cars engine shut down while driving. Once we got it stopped we put it in park and the car started and we drove it 30 minutes home.

Subject: Safety Concern Regarding 2017 Genesis G80 Dear NHTSA, I am writing to report an ongoing issue with my 2017 Genesis G80. While driving, I have experienced a significant safety concern related to the vehicle's acceleration. Specifically, when accelerating at various speeds, the vehicle begins to jerk abruptly and violently, causing a potentially dangerous situation on the road. After seeking advice, I was informed that the problem might be related to the engine malfunctioning or failing. I am deeply concerned about the safety risks this poses, both for myself and others on the road. I would greatly appreciate any guidance or investigation into this matter to ensure the issue is addressed promptly. Thank you for your attention to this serious safety concern. Sincerely,
 [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
