What 305 owners told NHTSA about the 2015 Hyundai Genesis Coupe

Driver side front turning signal/Daytime Running light burns out constantly. I have replaced that bulb at least 6 times since purchasing the car in 2018. Dealer confirmed it's common with my vehicle, and advised me to use OEM bulbs only as other bulbs would blow out faster. After the first bulb was replaced with a dealer OEM and that blew out within a few months, I purchased one from auto zone and it burned out within a week. Have been using OEM bulbs ever since. I have two friends with the exact same year make and model, and they have experienced the same issue. You can also see many threads hear describing the issue: https://www.google.com/search?q=2015+genesis+sedan+turn+signal+bulb+burns+out+site:genesisowners.com With a bulb that burns out constantly, there's a risk of people not wanting to swap them out and just not having a left turn signal on front of vehicle, this poses a safety risk to the driver and to everyone around them if they cannot properly signal their intent. One of my friends has chosen this route, after swapping the bulb 3 times, he has refused to do it any further. The indication that the bulb has burned out is a "Hyper Flash" meaning the left side turn signals will flash more rapidly than before to indicate a bulb has burned out. Many users have switched to LED lights to assuage the issue, however this is an aftermarket solution, not one that is provided by the manufacturer.

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.

While driving on the highway (70mph) the front sunroof panel unexpectedly exploded raining glass all over the driver and vehicle. Prior to the sunroof exploding there were no signs of it being compromised (dents, scratches, cracks, etc.). Very small shards of glass were impaled into the drivers head and hands. After trying to have the sunroof repaired by two separate Hyundai dealerships who were unable to perform the work, the vehicle had to be repaired by an auto body shop.

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.

The positive battery terminal has a design flaw where it will wholly lose conductivity with the battery post due to vibrations, stress and age. After numerous dealer visits where "nothing was wrong" I began to diagnose the issue myself. I tracked it down to faulty positive battery terminal, which due to the lack of manufacturer availability I had to correct myself. It seems to be such a widespread but "unknown" issue with the entire vehicle model that I made a repair guide on the subject with photos: https://genesisowners.com/genesis-forum/threads/improved-positive-battery-terminal-box.32768/#post-411757 The primary issue at stake is the sudden, unexpected loss of power steering when maneuvering at low speeds. The vehicle will lose additional safety systems when the battery power is interrupted, such as collision avoidance, parking sensors, airbags and even powertrain control in extreme cases. No manufacturer diagnostic codes will ever be set as the systems in the vehicle do not account for sudden unexpected power loss. Problem is aggravated by objects on trunk floor resting on terminal box. The secondary issue is that when a power interruption occurs while the vehicle is in operation, the vehicle will not properly shut down when the ignition is turned off. Rather than unlocking doors and assisting handicapped drivers via the easy exit seat feature, the car completely dies and does not wake back up. Vigorous door slamming or any other large impact to the body of the car will sometimes bring systems back online, by fractionally moving the positive battery terminal. If systems do not return, the driver is unable to lock the doors or open the trunk. Hyundai does not make the positive terminal a replaceable item, rather, it's only sold as a combined part with a $1400 battery cable (plus 8 hours labor). Dealers and owners alike are averse to replace this part for such a high price, when the battery terminal itself is worth less than $20.

I should have listen to all the noise in the market but instead I went any head and did it anyway. The start a knocking sound out of no where. My problem is why do they built these engines when one have to buy another one before the car even gets old enough.

I was driving on the interstate and the sunroof suddenly shattered and glass fell into the car. With the falling glass it was startling and without a calm response could have resulted in a multiple car crash and potential fatalities. Also, the falling glass could've caused physical injury. I was told by the local dealership to wait for 50 days before they would be available to inspect it. There were no symptoms of the problem prior to it happening.

Upon driving many warning lights light up and make warning signals on the instrument dashboard. These warning lights light up at the same time or in succession and include: check bid system, tire pressure, check engine light, skid control, check bsd system, and others. In addition, brakes become sticky and steering is affected. Worse yet, car slows down on its own as it engages crash avoidance system.

The electronic parking brake system engaged and remained engaged such that the car could not be driven. It could not be reset through any available means and no manual method exists. This occurred while the vehicle was stopped thus not a substantial safety risk for the particular episode, however this was a complete failure of a portion of the braking system which made it impossible to move the vehicle. It was towed on a flatbed truck and required skates under the rear tires to be placed on the truck. The Hyundai dealer confirmed that the entire system must be replaced and the vehicle remains disabled at the dealer as the parts are not available. There were no warning indicators, until the event occurred when the EPB and AUTOHOLD indicators lit, and the vehicle diagnostic system alerted a problem with the electronic parking brake system.

ESC failed. I was attempting to make a left turn from a stopped position at a typical intersection. I lost control of the vehicle as it started to fishtail once I began the turn. Brakes did not respond and I ended up hitting the curb on the outer lane with both front and rear tires. Side curtain and passenger seat airbags deployed. Vehicle is now a total loss. I believe the faulty ESC poises a lot more risk that just a fire. From other reports on genesis forums by consumers like me, this problem with Hyundai's ESC seems to be a common and reoccurring problem. Recall should be updated to include that ESC may fail and makes the vehicle unsafe to drive.

The DAB module assembly (air bag system) driver's side has to be replaced due to failure. Only warning was a creaking sound from the steering column when turning. Although I have an extended warranty, never been in an accident, and the car is only 6 years old with 44,000 miles, the extended warranty for the air bags is only for 5 years. The cost to replace the DAB is over $900.00. I feel strongly that Hyundai should cover the cost.

The rear passenger door will not open from inside or from outside of the vehicle. The door lock mechanism has failed internally while the door was shut. This causes a safety issue as passengers are not able to exit the vehicle in an emergency event. Worse, a child car seat is not able to be accessed as the door will not open. There are not warning lights in the vehicle to alert you that the door lock/handle mechanism has failed. Hyundai/Genesis will not repair the defective components under warranty, as they consider it a wear item. As the door will not open it is extremely difficult to repair this issue. The door panel has to be cut off which renders it destroyed. The door lock/latch mechanism has failed at 60000 miles and with a vehicle that is 6 years old. This is a huge safety issue as people will become trapped in a crash, which can lead to injury and loss of life.
