2015 Hyundai Genesis

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.

Rt Side Day Running Light. This model Hyundai Genesis uses what is suposed to be an intermittent bulb / socket for turn signaling. In this 2015 model it is so it's on ALL THE TIME as driving lamp. Bulb overheats, burns out, scorches the socket. Bulbs now last less than 5 months. Dealer replaced scorched scoket and bulb today. $169.00 Not under warranty

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.

The 2015 Hyundai Genesis model was produced with a halogen daylight running lamp that is also the directional turn signal; because of this dual function, the directional fails. When you google this issue, there are hundreds of other owners who have either made videos or blogged about the same issue. I have spent over $1000 dollars trying to fix the issue and when it was under warrantee, the dealership must have spent three times as much without success. Drivers coming at you, have no idea that you are turning or not. Wiring harnesses have been changed, switches replaced, multiple bulbs and I have even changed out the headlight assembly. Hyundai is aware of this issue and has turned their backs on their customers

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.

The contact owns a 2015 Hyundai Genesis. The contact stated that the fuel gauge was providing an inaccurate fuel reading. The contact stated that the fuel gauge displayed that the fuel tank was full, with 200-300 miles to empty. The vehicle was taken to an independent mechanic to be diagnosed. The vehicle was not repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 118,806.

The rear passenger brake/reverse light and rear camera were sporadically working until they all stopped working completely. After some research the cause of the problem is the trunk wire harness which has failed (20-BE-007H). Unfortunately this fix isn't know to dealerships who I've had attempt to fix the problem, which leaves me without a brake light, reverse light, and reverse camera.
