2016 Hyundai Genesis Engine Problems

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 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.

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

The oil pressure sensor is causing a oil light. This is a known issue on these cars and engines due to a faulty sesnsor. There even is a recall in Korea for the same cars; however, there is not one in the US.

The contact owns a 2016 Hyundai Genesis. The contact stated that while driving at approximately 45 MPH, the oil warning light was illuminated. The contact stated while depressing the accelerator pedal, the vehicle hesitated before gaining forward momentum. The contact stated that the failure was intermittent and occurred while slowing traffic or a traffic signal. The oil warning light was occasionally illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the oil pressure switch needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 51,000.

I have been told to not park my car in the garage or near any structure. A fire could happen any time, while driving, or parked in the garage or outside the garage. I've spoken to a Genesis representative who told me they could not give me a loaner until they have a fix. My wife is [XXX] and handicapped. I'm [XXX] and we're very concerned about our safety. We live in a condo community that has no room to park on the street, so I'm parking behind my garage. I believe all these things are special circumstances and warrant special dispensation. It sure would take some stress out of lives if we could get a loaner. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2016 Hyundai Genesis has several open recalls. I cannot get a dealership to help me get these issues resolved. One recall in particular Hyundai recall number 254 is causing major safety issues. My car does not start 90% of the time without being jumped and now the car will die out while driving. It has caused me to almost wreck several times. I have called all of the local Hyundai dealerships none of which say they can get me in for weeks and that there is no fix for my problem. If I do get to someone to book an appointment, when they hear the problem they put me on permahold and then the line disconnects! This is a major safety issue and needs to be fixed by Hyundai immediately.

We have a 2016 Hyundai Genesis 3.8L Sedan w/90,000 miles and the Oil Pressure Sensor light came on. It seems, based on our research, that this is a common issue with this engine. The repair is quite expensive and seems to be a design flaw.

Car is shutting off when stopped. When it shuts off, the engine light comes on, the battery lights, the EPS, the master warning light, the FCA system light, and the EPB. When the engine shuts off, I still have power to my car and the radio still playing but nothing to my engine. I brought my car to 2 different mechanic and brought it to the dealership today and they are saying there’s nothing wrong with my car. My car have been shutting off all this month and that’s not normal,

The engine oil pressure sensor is failing on a lot of these vehicles at around 60k miles. The repair is costly due to where the sensor is located. Repair is more than $1000 dollars for a part that costs $180. I believe a precedent was set when in Korea Hyundai was forced to issue a recall.

Car experience loss of control to accelerator while driving on major highway. The vehicle's speed coasted down from highway speed of 65mph to low 50s before vehicle was safely stopped on roadside emergency breakdown lane. This incident could have easily resulted in a collision with faster-moving traffic. The vehicle has been transported to a dealer for inspection to determine the cause, however this episode appears very similar to a documented issue in 2016 with a faulty fuel harness and low pressure fuel pump. No warnings or indications were present until after the car was turned off and restarted.

IF I DO NOT FILL THE AUTO WITH A PREMIUM BLEND GASOLINE THE CAR WILL INCONSISTENTLY OVER REV AND JERK INTO GEAR IF I ACCELERATE SOMEWHAT SUDDENLY. THIS RESPONSE IS QUITE ODD AND COULD CAUSE AN ACCIDENT SINCE THE CAR KICKS INTO GEAR RATHER HARD AFTER ACCELERATING AND THEN LETTING OFF THE GAS. THE SENSATION IS THE SAME AS EXPERIENCING A LIGHT BUT LOUD REAR END COLLISION FROM BEHIND. THE CAR IS LUXURIOUS AND BIG THEREFORE, YOU WOULDN'T EXPECT THIS TYPE JOLTING FROM THE DRIVE TRAIN.

ABOUT A MONTH BEFORE THE INCIDENT, THE VEHICLE WAS FULLY IMSPECTED IN OFFICIAL DEALERSHIP, NO ISSUES REPORTED. A FEW DAYS BEFORE THE INCIDENT, THE WIPERS STARTED WORKING WITH THE ENGINE OFF; I SCHEDULED AN APPOINTMENT FOR AN INSPECTION. THE VEHICLE WAS LEASED WITH ABOUT 10 MONTHS LEFT ON THE LEASE. ON APRIL 13, 2018 AFTER DRIVING FOR 1,5-2 HOURS, I PARKED IT AND WENT TO THE OFFICE FOR 10-15 MINUTES; ON MY WAY BACK TO THE VEHICLE I HEARD THE FIRE TRUCKS COMING; AS I WAS APPROACHING MY VEHICLE I REALIZED THAT MY VEHICLE WAS ON FIRE. THE INSPECTOR REPORTED THE ENGINE EXPLOSION DUE TO MANUFACTURERS PROBLEM. SO BASICALLY HAPPY TO BE ALIVE AS NOBODY KNOWS WHAT WOULD HAD HAPPENED WITH ME AND MY KIDS IN THE VEHICLE DRIVING ON A HIGHWAY; SO AFTER MORE THAN 3,5 MONTHS HYUNDAI FINNCIAL STILL DID NOT CLOSE THE CASE ALTHOUGH THEY STATED THAT THEY ARE IN THE PROCESS OF PAYING OFF THE VEHICLE. NOBODY EVER SAID SORRY; I CALL TO HYUNDAI / HYUNDAI FINANCIAL EVERY DAY AND ALL THEY DO IS THEY TRANFER ME FROM ONE DEPARTMENT TO ANOTHER; THE CASE MANAGER ASSIGNED TO OUR CASE NEVER PICKS THE PHONE, NEVER CALLS BACK, TO REACH HIM I NEED TO CALL TO THE SUPERVISOR AND COMPLAIN AND ONLY THAN I RECEIVE A CALL FROM HIM. 2 MONTHS AGO HE STATED HE WOULD CLOSE THE CASE THE COMING MONDAY. NO ACTIONS SINCE THEN SO FAR.
