On [XXX], my vehicle was not starting at all, prompting me to seek professional assistance. Subsequently, the car was towed to a nearby auto shop for a comprehensive diagnostic. The findings indicated that the starter was the root cause of the issue and required replacement. Additionally, a battery replacement was deemed necessary. Coincidentally, on the same day, a recall notice was issued regarding the starter, citing a fire risk associated with the component. In light of the recall notice, the vehicle was relocated from the auto shop to my residence. On [XXX], the car was then towed to the dealership for further investigation and confirmation of the starter diagnostic, as advised by Hyundai corporate by an agent named, Doreen. I contacted Hyundai corporate on Friday, [XXX] , seeking guidance about the starter diagnosis. Their recommendation was to have the car towed to the dealership to validate the starter issue. She stated they will be able to expedite the resolution process at a national level once the dealership confirms the diagnosis. Today, on [XXX], Capitol Hyundai in San Jose, CA, associate by the name of Ali Lee, informed me that the starter was not the culprit; rather, it was identified as a "faulty" new battery installed six months ago. This revelation is disconcerting, especially considering that the car, parked for six days, should not have been able to start if the issue was solely related to the battery, as confirmed by the dealership. This report aims to document the sequence of events for future reference and to address potential safety concerns associated with the recalled starter, which poses a fire risk. Moreover, I would like to bring to your attention some pre-existing issues that might be connected to the recall, including light flickering while driving, headlights turning completely off automatically at night on the freeway & challenges w the car windows when using the designated buttons.

I was driving the car, and without warning, it just said engine overheating and shut off. If I had pulled out in front of someone, I could easily have gotten killed. There was no prior indication of anything wrong. Just riding down the road and it just shut off for no reason and would not restart. Towed it to the dealership and they told me that I need a new electronic control module and quoted a price of $4,000. That is freaking outrageous for something that should never have gone wrong in this car. I researched online and there are multiple Hyundai Genesis sedan owners have had a problem with the electronic control module going out for no reason. This is something Hyundai should be held accountable for as it is a major safety hazard. For your car to just shut off for no reason while driving it, is extremely dangerous and life-threatening.

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.

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 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.

Rear passenger door failed to open from outside or inside vehicle. Possible door actuator or module. Two car seats with babies inside vehicle,couldn’t open door. Very dangerous in case of emergency. Vehicle has only 54000 miles, with extended warranty, dealer not honoring the warranty, item(s) not covered. Dealer says it’s wear& tear. Not acceptable, it’s a safety issue.

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.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Hyundai Genesis Coupe verdict →
