2015 Hyundai Genesis

The contact owns a 2015 Hyundai Genesis. The contact stated that while stopped at a traffic light or while the vehicle was in drive, the vehicle failed to move, and the engine shut off unexpectedly. Several unknown warning lights were illuminated on the instrument panel. To restart the vehicle, the driver had to shift the gear selector into park and then press the start button. The vehicle was taken to a local dealer, but the dealer was unable to duplicate the failure or determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 120,000.

The vehicle exhibits a severe vibration and shaking at normal highway speeds, most notably around 70–80 mph. The condition is repeatable and occurs during steady freeway driving. The vibration is strong enough that the vehicle feels unstable and unsafe to operate at typical highway speeds. This condition significantly affects safe freeway operation. Due to the severity of the shaking, I no longer feel comfortable or safe driving the vehicle at or above normal traffic speeds, which increases risk when merging, maintaining speed with traffic, or responding to road conditions. The problem has been reproduced and confirmed by authorized dealerships. Multiple inspections and repair attempts have been performed over several months for the same vibration concern. Major drivetrain components, including the rear differential and driveshaft, were replaced, but the vibration remains unresolved. The servicing dealer has stated they do not have a further diagnostic path and are unable to continue addressing the issue. The issue has been ongoing since approximately November 2024 and has not been resolved despite repeated service visits. No warning lights or messages are present. The vibration is speed-dependent rather than engine-speed-dependent. The vehicle remains available for inspection upon request.

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.

I took my car to South Shore Hyundai sometime in May 2023 to find it has internal transmission failure at 107,500 miles and a new transmission would cost $6,200 and change. This transmission issue has been gradually getting worse since around 87,000 miles when I did a computer reset to attempt to resolve it. The issue didn’t show up on a computer and it wasn’t an everyday issue at 87K but now it’s an everyday issue and concern while driving. I also believe I had the transmission examined at around 97K by allowing Advantage Hyundai Service in Hicksville NY to test drive the car for over a day and they found nothing. I was hoping to fix the transmission under the 100K mile powertrain warranty promised to me by my salesman but not executed on paper as I was an inexperienced buyer and was taken advantage of. About 1 year after I bought the car the drivers heated seat stopped working and would cost me about $2,500 to fix which I never paid for. Absolutely loved the car but it costed me so much in repairs over the years and the transmission failure has me so upset. I wish I could get it replaced as I still owe $ and can not afford a new car not even an old car for $5000 yet.

There are multiple problem points with this vehicle that become apparent far earlier than they should including but not limited to 1: Starter Motor complete failure at 70k miles (affects every single 3.8 2015-2017 genesis sedan) 2: Sunroof front panel seal degradation 3: Shuddering driveshaft early into new ownership (also afflicts most of these vehicles) 4: BRAKE BOOSTER AND MASTER CYLINDER SUDDEN COMPLETE FAILURE 5: Oil Pressure sensor improper calibration All of these issues have been checked by multiple service centers at Hyundai/Genesis dealers, all of them confirming reluctantly that these issues affect all genesis models similar to mine. The braking issue is the worst, happens suddenly and at a random point in time, and costs thousands to fix. The starter motor failure is very common, and every dealer kept forcing me to replace meaningless parts until the car would no longer start and then they admitted it needed a new starter. The front panel between the sunroof and the windshield has rapidly degrading rubber seals, which will loudly shake and move around while driving. The driveshaft will shudder when the vehicle is cold and it’s sub 80° outside, even if the engine has warmed to operating temp. The oil pressure sensor rapidly breaks just months after the car is brand new, with it on average reading a much lower oil pressure than is actually being applied. All of these issues have been replicated, and only the faulty oil pressure sensor had a warning light, no light for the faulty brakes, starter, or driveshaft issues. The more I research into genesis, the more I realize that these issues happen just a couple thousand miles after new, and affect every single genesis model similar to mine.

Got oil changed at Genesis dealership at 79K miles. Within a day, Low Oil Pressure light began to turn on and off sporadically. Usually showing up when idling and turning off while accelerating. Took car back to dealership and they identified a faulty oil switch (which appears to require a significant amount of labor to access/replace). This has already been recalled in Korea as it has been happening to many vehicles around the 60-70K mile mark and it is a major safety issue (people driving with a faulty sensor may get complacent on urgency if the warning light). I sincerely hope Hyundai/Genesis USA issues a recall for the faulty oil pressure switch issue and this most definitely should be covered under the 100K miles Powertrain warranty.

Transmission at low speeds going into the 1st gear has a hard pull. Rmps jumps from 2to4 and back down until it reaches 2nd gear and it doing it again. After that it's smooth. Only way to avoid this is drive fast. Other genesis owner has the same issues. They say to change the Transmission fluid but it will eventually do it again. It makes alot of people that drive my car really scared.

The contact owns a 2015 Hyundai Genesis. The contact stated while driving at various speeds, the vehicle loss motive power and stalled, with the accelerator pedal depressed. There was no warning light illuminated. A dealer was not contacted. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000.

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
