2015 HYUNDAI GENESIS Engine Problems

The contact owns a 2015 Hyundai Genesis. The contact stated that while stopped at a red light, the vehicle started shaking with the check engine warning light illuminated. The contact stated that while depressing the accelerator pedal, the vehicle accelerated but failed to exceed 20 MPH. The vehicle was steered to the side of the road and shifted into park(P). The vehicle was restarted, but the failure persisted. The vehicle was taken to an independent mechanic, where a handheld diagnostic machine retrieved DTC: P2106, P0638, and P2110. The vehicle was taken to an independent mechanic, where it was diagnosed that the throttle body and the foot control throttle needed to be replaced. The contact was also advised by the mechanic that there may be an electrical system issue with the vehicle. The vehicle was not repaired, but the codes were reset. The contact took the vehicle to the residence and replaced the throttle body and the foot control throttle, but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 94,600.

After Hyundai performed a recall service on my vehicle, the radiator hose burst while I was driving on the highway, causing the engine to fail completely. Smoke came from the engine compartment, and I had to pull over immediately with my family to avoid a serious accident. Before the recall, the vehicle had no issues and ran perfectly for three months after purchase. The problem occurred only a few days after the recall service, which included work on the ABS module. Hyundai refused to take responsibility, even though this failure happened right after the recall repair. The dealership and manufacturer did not inspect the vehicle properly and made their decision based only on a phone conversation. This is a severe safety concern because the engine failed suddenly on the highway. I believe this failure is directly related to the recall work performed under NHTSA Recall #21V160000, which is still listed as incomplete on NHTSA records.

I've been bringing my car to a repair shop over and over for the past month. Myself and the repair shop had to put a quart of oil once a week in the vehicle. I have spent on numerous things to get down to the problem. The engine is leaking oil. I downloadwd proof leading to the problem I need to get fixed. The problem is still there

I just purchased a 2015 Hyundai Genesis 3.8 4 door sedan 1/10/2025. Randomly lately the car does a slight jerk and the screen goes black, that happened about 5 times in just a few weeks. twice the car shutoff and back on at slow speed coming to a stop, and then entering into a parking lot. same day at 65-70 mph on the freeway it jerked hard and the engine turned off and on. Very scary and dangerous!! I did not see anything on recalls that would pertain to this happening. All recalls have been done on this car, that's what it indicated. Service guy wasn't sure. this is a random thing. I could leave my car with them but they'd have to drive it a lot for long periods before it might actually happen again.

The contact owns a 2015 Hyundai Genesis. The contact stated that the driver's side mirror failed to adjust properly to view the surroundings on the driver's side of the vehicle. The failure was causing issues and a need for chiropractic care due to the contact needing to manually turn and adjust to safely view oncoming traffic, which aggravated previous neck and back injuries. The vehicle was taken to the dealer, who diagnosed that the mirror had failed and needed to be replaced. The vehicle was not repaired. When having the oil changed, the dealer informed the contact of 2 recalls; NHTSA Campaign Number: 21V160000 (Service Brakes, Hydraulics) and NHTSA Campaign Number unknown (manufacturer number 252) and Service Campaign Manufacturer Number 965 (NHTSA ID Number unknown). The fuel module, fuse assembly, and relay were replaced or repaired. The vehicle was kept for the remedies to be completed; however, approximately 2-3 weeks after the remedies were completed, the vehicle would hesitate when driving at various speeds, the engine would stall without warning, and the vehicle would fail to start on initial start-up, intermittently. The contact used engine cleaner, seafoam, and Lucas cleaner for the engine; however, the engine failure persisted. The vehicle was towed to the dealer, who was not able to provide a diagnosis or make contact for any updates since the vehicle's been returned. The vehicle was not repaired. The manufacturer was informed of the failure and had 2 cases of the vehicle. The failure mileage was approximately 96,000.

A well known and documented case of the oil pressure sensor switch failure has occurred on my car. Hyundai has recalled the car for this problem in South Korea. My switch failed at slightly over 60,000 miles. The switch is in an inaccessible location on the engine for even a good DIY owner-mechanic, which makes it very expensive to replace. This is a very common discussion on Hyundai owner forums and elsewhere.

Oil pressure sending unit sensor failed and triggered oil light to come on.

Oil light is on after 65k miles , defective component recalled in Korea already

The contact owns a 2015 Hyundai Genesis. The contact stated that the vehicle failed to start. The vehicle was towed to the dealer, where it was being diagnosed. The vehicle had remained at the dealer for four months. The vehicle was not diagnosed or repaired. The contact stated that the failure could be related to NHTSA Campaign Number: 24V107000 (Electrical System). The manufacturer was not notified of the failure. The failure mileage was approximately 61,000.

Factory recall 24V-107: On [XXX] took car to Haselwood Hyundai of Bremerton WA. for MANF. recall Genesis Starter Solenoid water contamination. Recall was completed in 2 hours when driving home car went into emergency mode and shut down on freeway with completely dead battery. Was told by dealership they would not pay 1200 tow bill. Applied for AAA membership and was approved. Car was towed back to dealership on August 28th with approx. 100 miles driven since Aug 9th. Dealership had no idea that costs would be reimbursed by Hyundai. Had they known this the car would have been towed ASAP after breakdown. Note: This vehicle had no issues prior to this factory recall being installed. On August 29 service adviser Brandon said Alternator and battery needed replacement. This made no sense because car had no electrical problems prior to factory install. Authorized dealer to replace this equipment if necessary since I would be reimbursed. Sept 2nd Paid dealer $1,567.00 for repairs. After leaving dealer car ran for 62 miles went into emergency mode with completely dead battery. Sept 3rd car again towed into dealership. My car has run for a total of 4 hours since Aug 9th factory recall repair. I've been without transportation going on 4 weeks because of this incident. Hence, I write to text to you asking for assistance in getting this incident over with. I thank you in advance for your time and interest in this request.

Engine warning light is showing up constantly, so visited Hyundai dealer, Valencia, but did not do anything. When visiting another repair shop, technician advised it is related to Stater Assembly Safety Recall. Hyundai did not do anything regarding this recall even there is probable fire explosion. It is seriousely worried about this matter. Please help this one. Thank you.

On [XXX], my vehicle was not starting at all, prompting me to seek professional assistance. Subsequently, the car was towed to a nearby auto shop for a comprehensive diagnostic. The findings indicated that the starter was the root cause of the issue and required replacement. Additionally, a battery replacement was deemed necessary. Coincidentally, on the same day, a recall notice was issued regarding the starter, citing a fire risk associated with the component. In light of the recall notice, the vehicle was relocated from the auto shop to my residence. On [XXX], the car was then towed to the dealership for further investigation and confirmation of the starter diagnostic, as advised by Hyundai corporate by an agent named, Doreen. I contacted Hyundai corporate on Friday, [XXX] , seeking guidance about the starter diagnosis. Their recommendation was to have the car towed to the dealership to validate the starter issue. She stated they will be able to expedite the resolution process at a national level once the dealership confirms the diagnosis. Today, on [XXX], Capitol Hyundai in San Jose, CA, associate by the name of Ali Lee, informed me that the starter was not the culprit; rather, it was identified as a "faulty" new battery installed six months ago. This revelation is disconcerting, especially considering that the car, parked for six days, should not have been able to start if the issue was solely related to the battery, as confirmed by the dealership. This report aims to document the sequence of events for future reference and to address potential safety concerns associated with the recalled starter, which poses a fire risk. Moreover, I would like to bring to your attention some pre-existing issues that might be connected to the recall, including light flickering while driving, headlights turning completely off automatically at night on the freeway & challenges w the car windows when using the designated buttons.

Oil pressure sensor is faulty and has gone out at ~74k miles. Looking into it, this is a known issue and has been recalled in Korea. The sensor is in the engine block and is a very costly repair. This needs to be recalled in the US!!

The oil low-pressure warning light is frequently on while the engine is operating from idle to approximately 2,000 rpm. Engine operation is normal, including high performance. Complaints of this condition abound on Genesis Forums. Beside the lack of a true low oil pressure warning that may result in severe engine damage, a safety issue is present if that damage occurs on roadways with no way to escape traffic flow.

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.

When driving at the speed of 20 - 25 MPH the car feels like its skipping or struggling to shifting into the next higher gear. Then all of a sudden it feels like someone rams into the back of us. Then the car will not shift into the next. I took the car into Coconut Creek Automotive LLC. The car just sat there for almost 3 months. They tell me that they could not duplicate the problem. I spoke with a service rep that told me he felt the problem. The Manager said to me that the car had to be driven and the problem displayed 5 out of 10 times. My car was there for almost 3 months and only drove 12 miles.

Driving and car just quit. Clock turned, wipers went crazy, and then smoke came up the front windshield from the engine. I bailed and left it in the road. Awful and dangerous situation. Dealership wasn’t excepting Genesis anymore. Towed to a dealership 50 min away. Told the engine failed.

I DON'T KNOW IF IT WAS ELECTRICAL OR ENGINE RELATED. THE OIL PRESSURE LIGHT WOULD COME ON WHILE DRIVING - ALL CONDITIONS - SLOW, FAST, STOP-AND-GO BACKROADS AS WELL AS DURING STEADY HIGHWAY DRIVING. WHILE HIGHWAY DRIVING AT ONE POINT, THE OIL LIGHT CAME ON AND THE CHECK ENGINE LIGHT ALSO COMES ON AND THE FUNCTIONING OF THE CAR IS AFFECTED (POWER, STEERING ETC.) FOR A BRIEF TIME, THEN IT WENT BACK TO NORMAL. IT FELT LIKE THE CAR TURNED OFF WHILE I WAS DRIVING ON THE HIGHWAY AND THEN CAME BACK ON.

in cold weather the engine displays a message that the oil pressure is low. This issue has been recalled on this same model in south korea, where all of these cars are manufactured.

1.ENGINE WILL NOT SHUT OFF WHEN VEHICLE IN PARK. HAD TO DISCONNECT BATTERY. there was no warning. 2. LKAS warning light remains on. 3. Caution light remains on on the dash. 4. Anti-braking system highlights when immediate car in front of me makes a turn without me being close to it. The first thing the dealer asks is do I have extended warranty! They stated they couldn't get to the repair until maybe Thursday. I'm really afraid to drive my car.

MY 2015 GENESIS HAVING STARTING ISSUE. I WENT TO YOUTUBE & LOTS OF PEOPLES HAS POSTED THEIR VIDEOS WITH SAME ISSUE. GENESIS AS A COMPANY NOT DOING ANYTHING TO CORRECT OR RESOLVE THIS RECALLS ISSUE.

THE CHECK ENGINE LIGHT COME ON FOR NO REASON. THE CAR LOCKED ME OUT WHILE RUNNING AND BOTH KEY FABS WOULDN'T UNLOCK IT FROM THE OUTSIDE. THE SMART TRUNK DOESN'T WORK. WHEN YOU LOCK THE DOORS, THE DRIVER'S SIDE WON'T LOCK.

VEHICLE WOULD NOT SHIFT UP TO THE NEXT GEAR AND AND STARTED ATTEMPTING TO SHIFT BUT FAILING EVERY TIME AS IT PASSED 2000 RPMS. INCIDENT HAPPENED WHILE PASSING ANOTHER VEHICLE, AFTER AN EXTENDED TIME OF VEHICLE NOT BEING ABLE TO ACCELERATE WHILE ATTEMPTING TO PASS THE BRAKES HAD TO BE APPLIED IN ORDER TO AVOID A COLLISION WITH AN INCOMING VEHICLE. THE VEHICLE LATER FAILED COMPLETELY AND ALL POWER FROM THE ENGINE WAS LOST AND STARTED RAPIDLY DECELERATING THEN FINALLY CAME TO A COMPLETE STOP. INSTRUMENT AND ELECTRIC POWER WAS STILL ON BUT THERE WAS NO POWER FROM THE ENGINE. VEHICLE WOULD NOT MOVE FOR ABOUT 15 MINUTES, THEN IT FINALLY HAD LIMITED POWER TO 45MPH

I WAS DRIVING NORTHBOUND ON I-295 IN WASHINGTON, DC WHEN MY CHECK ENGINE LIGHT ILLUMINATED AND THE CAR BEGAN TO SLOW DOWN IN EXTREMELY HEAVY TRAFFIC AND I LOST THE ABILITY TO ACCELERATE. I ATTEMPTED TO ACCELERATE IN ORDER TO GET MY VEHICLE OFF THE BUSY HIGHWAY AND TO A SAFER LOCATION, BUT I WAS NOT ABLE TO GO MORE THAN A FEW METERS. IT WAS FORTUNATE THAT I WAS NOT SERIOUSLY HURT OR KILLED. THIS IS CLEARLY A SERIOUS SAFETY ISSUE AND I AM SURPRISED THAT THERE HAS NOT BEEN A RECALL TO FIX THIS PROBLEM, ESPECIALLY CONSIDERING THAT IT APPEARS TO BE SOMETHING THAT HAS BEEN HAPPENING TO MANY HYUNDAI VEHICLES FOR SOME TIME NOW. AFTER MORE THAN ONE (1) HOUR, I WAS RESCUED BY A TOWING COMPANY THAT LEFT MY CAR AT THE DEALERSHIP. THE DEALERSHIP HAS DISCOVERED THAT I REQUIRE AT LEAST A THROTTLE BODY ASSEMBLY TO REPAIR THE ISSUE AND HAS ORDERED THE PARTS WHICH MEANS THAT I AM RENTING A CAR UNTIL THE REPAIRS ARE MADE (THE PART WILL TAKE SEVERAL DAYS TO BE DELIVERED). AFTER THE THROTTLE BODY ASSEMBLY IS INSTALLED, THE DEALERSHIP WILL RESCAN TO SEE IF THAT ELIMINATES SOME OF THE OTHER CODES THAT WERE DISCOVERED.

THIS IS AN ONGOING SAFETY ISSUE THAT I'VE TRIED TO GET THE DEALERSHIP TO ADDRESS. FROM A STOP OR SLOW IDLE, THE ENGINE EXHIBITS ACCELERATION HESITATION. THIS HESITATION LASTS UP TO 2 SECONDS AND WHEN TRYING TO MERGE INTO TRAFFIC HAS NEARLY RESULTED IN ACCIDENTS NUMEROUS TIMES. I BELIEVE A HYUNDAI WHISTLE-BLOWER CAME FORWARD RECENTLY TO EXPOSE THIS ONGOING ISSUE BUT HYUNDAI HAS YET TO ADDRESS IT.
