2015 Hyundai Genesis

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.

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.

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.

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
