What 305 owners told NHTSA about the 2015 Hyundai Genesis Coupe

While driving I noticed an engine noise/rattle about 3000RPM. The engine seemed to run fine but was making this abnormal noise. At 73,083 miles I towed the car to the Hyundai dealer. They found an anomaly in cylinder #5 and recommended engine replacement but refused warranty powertrain coverage because I am not the original owner. They also refused goodwill coverage even though this is a known issue with Hyundai engines.

My turn signals burn bulbs burn out constantly (2x a year) and I drive approx 8k miles per year. Turn signals are a basic basic safety issue & given that if you explore the Hyundai Genesis form it is a KNOWN faulty wiring design. . It is not simply a matter of changing a bulb - it’s very difficult to get to. Hyundai knows this issue since they changed the housing design for the 2016. I believe they owe their customers a safe option.

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.

Car goes completely dead and can happen at any time, will be dangerous if it happens while driving seems like there's a short on the leads on positive battery connection. Connection is tight and battery is good. The the leads that go to positive terminal seems to have a short, when it goes dead will have to wiggle slightly and power comes back. Like I said terminals are tight and battery is in good working condition. So it's the leads at before positive terminal.

I have a 2015 Genesis Sedan 3.8 My cars instrument cluster glitches! Sometime when driving or only starting the car my cluster lights up all of the warning lights. Also it shows incorrect speed. I have found that Hyundai did recall some of of the 2015 models with this problem but mine doesn’t qualify for the recall! Some of the safety features of the car like the bsd system stopped working cause of this.

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.

Steering wheel sticks in turns, requiring the wheel to be pulled back to center. This is most noticeable on long sweeping highway turns and adds additional effort to operating the vehicle. This is the second time I've had this problem. The first time, at approx. 30k miles, the Hyundai diagnosed and replaced the electric power steering rack, which resolved the issue. Now at 65000 miles, the same issue has returned. There are a number of other people posting on the genesis forums about this same issue.

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

The left rear passenger door does not open from inside or outside. I have looked online and see that this or similar problems affect many Genesis sedans as well as other Hyundai vehicles. We needed to seat two young children in the back seat and realized how dangerous it is if something happens and the car door can't be opened from inside or outside. How would rescue teams extract the passenger? How could the passenger extract him/herself? Many people reported paying a lot of money to the dealership to repair this problem. I believe this is a safety hazard that the company should be responsible for. This problem began recently, with no warning. The key fob does not open the door either.

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.

Both the left and right turn signals have had to be replaced over 5 times EACH since I purchased the car in 2018. The first time it happened I took it to the dealer and they said the lighting harness was the problem and they replaced it at no cost since it was under warranty. Then the right one went out and again they replaced the harness free. Then the left went out again and since replaced harness was under a year old, they replaced it at no cost. That was Feb 27. 2020. Each side has gone out at least 4 times since Feb, '20. Please keep in mind I drove less than 5000 miles during 2021 due to the pandemic. Now the dealer says the entire head light assembly must be replaced to solve the problem. This is a real safety concern because other drivers need to know where I'm turning or I might get hit. Hyundai charges $1,100 to replace headlight assembly on each side-any discount given! So now I must replace the bulb about every 3-4 months on each side to feel safe driving. This a problem with their 2015 models because we have a friend who had the same problem

Head light control knob on the blinker handle. While driving, using the blinker, the headlights' turn knob is extremely sensitive. It has happened several times. Driving at night, turn on the blinker to go right, it also scrolls the headlight control and turns them off. HIGHLY dangerous in my opinion. Safety concern for myself and other drivers Mentioned this to Kingdom Kia of Rolla, MO. Service worker said she has heard of this complaint before. The light knob is very sensitive. Has not been inspected by manufacturer No warning lamps etc.

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.

The fuel door will not open, even with the emergency latch located within the trunk. A cursory search of reddit and other forums has revealed the problem to be widespread among other Hyundai owners, with no solutions offered by Hyundai or Genesis. The safety issue is obvious in that drivers will be stranded in unexpected places.

The brakes drag on the primarily on front passenger side and sounds like its cutting into the rotor. They've been replaced several times and after a few months the issue reappears. The issue can affect any of the of the four wheels. It's much worse during frequent braking, or 'stop and go traffic', and when it's warmer outside.

I was attempting to open the rear door to help my child exit the car when the exterior door handle broke off in my hand leaving me unable to open the door. Luckily there was no emergency and I was able to use another door. I was told this is a common problem with these door handles and feel it could create an entrapment issue under the worst circumstances.
