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.
2015 Hyundai Genesis electrical complaints
Page 4 of 5: complaints 71 to 100 of 111, newest first, as owners wrote them.
While driving the following codes would flash: AEB, BSM, TPMS, Also while the AEB code would flash it would limit my acceleration weather on the highway or local driving. These issues were reported to Hyundai America Corporate and I have a active complaint as well as a open appointment with a local dealership on 1.4.22. Lastly I do have a video of this taking place
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.
The contact owns a 2015 Hyundai Genesis. The contact stated while the headlights were on the auto setting, the headlights occasionally flickered on and off independently. The contact also stated that the air bag warning light also inadvertently illuminated. The vehicle was taken to the local dealer and was diagnosed with the wiring harness needing to be replaced. The vehicle was repaired however, the failure persisted. The manufacturer had been informed of the failure and informed the contact that an engineer would be sent out to inspect the vehicle. The engineer was not heard from and the vehicle was not inspected. The failure mileage was approximately 15,000.
1.ENGINE WILL NOT SHUT OFF WHEN VEHICLE IN PARK. HAD TO DISCONNECT BATTERY. there was no warning. 2. LKAS warning light remains on. 3. Caution light remains on on the dash. 4. Anti-braking system highlights when immediate car in front of me makes a turn without me being close to it. The first thing the dealer asks is do I have extended warranty! They stated they couldn't get to the repair until maybe Thursday. I'm really afraid to drive my car.
My 2015 genesis having starting issue. I went to youtube & lots of peoples has posted their videos with same issue. Genesis as a company not doing anything to correct or resolve this recalls issue.
Tl* the contact owns a 2015 hyundai genesis. The contact stated that while driving at various speeds, the vehicle seized as the battery, service key, temptuer control warning light illuminated. An abnormal odor appeared. The contact managed to coast the vehicle to the shoulder, turn the vehicle off and on which failed to start. The vehicle was towed to five star hyundai of macon 3010 riverside dr, macon, ga 31210 (478) 345-8927 however it was unable to duplicate the issue. The vehicle was test drove after the technician restarted the vehicle; still unable to duplicate the issue. The vehicle was not repaired. The failure recurred intermediately. The vehicle was towed twice to the dealer. The vehicle had been seen at the dealer over 10 times. The contact feels unsafe driving the vehicle. The manufacturer was not notified of the failure. The federal safety agency campaign number: 16v575000(electrical system) was mentioned as a possible solution to the failure however the VIN was not included. The failure mileage was approximately 60,000.
The car cut off on my twice different days while I was driving on one of the freeway once while turning into my drivingway 3rd I tried to start my car this morning started less than a mili second and would not turned back on
Blind spot warning system is not operating. After having it checked and fixed, the warning is back after threw days. Looks like this is a well known issue that hyundai does not want to repair or make better. After driving from a road trip on the interstate/highway, once I arrived to my destination, the bsd warning was displayed. No damage, and no collision.
The check engine light come on for no reason. The car locked me out while running and both key fabs wouldn't unlock it from the outside. The smart trunk doesn't work. When you lock the doors, the driver's side won't lock.
Rear driver side tail light and turn signal works intermittently. Moisture was accumulated in tail light housing. Hyundai dealers are aware of defect but have taken no corrective actions.
While driving at night with lights in automatic mode, the headlights will turn off for a few seconds and the dash will indicate the lights mode has changed, before the lights will turn back on. This has occurred multiple times typically at night along rural highways but has occurred along lit streets as well. It has happened while simply driving along a straight stretch of road as well as when turning or switching from brights to dims. This safety hazard has fortunately not yet resulted in losing control of the vehicle due to lack of awareness regarding position on the road and could result in a serious accident. Date listed is the most recent time the incident occurred.
Daytime running lights(drl) and front turn signal bulbs burn out very frequently due to the fact they are the same filament in the bulb even though they require a dual filament bulb. The wiring harnesses also show significant signs of overheating. This is a very widely-known issue in the online forums for this car and is a completely unsafe issue. The drivers side bulb is easy to replace, but the passenger side is not. I have replaced the drivers side 3 times and the passenger side 2 times in the last year. Between bulbs and mechanic fees for the passenger side, I have spent $200-$300 in the last year maintain this unsafe problem.
Back up camera. I have replaced the back up camera 3x and it is still messing up. No longer under warranty, when it was like I said it was replaced 3x. The back up camera acts up when put in reverse, it shows a blue screen at times other times it glitches and shows black and white, etc.
Please disregard and delete this voq. I am testing the system for a client to see what if any changes have been made in the last few years.

Headlights turn off an on when in auto mode, while driving
The power trunk hatch malfunctions, opening the trunk either partially or completely. Unfortunately it does not close completely unless using the trunk button inside the vehicle. One incident, the trunk attempted to close without warning or notice. No button was activated to close at the time. The trunk would open when the vehicle was stationary, in motion on the roadway, and when the vehicle was powered off. All were isolated instances. It is unknown what may be causing the malfunction, however has progressively became worst from the onset. I was able to utilize the "valet trunk lockout feature" for now, deactivating the trunk functions. I'm scheduled to meet with the hyundai dealership for an inspection of the vehicle soon. I've also contacted the manufacturer regarding this issue.
My headlights flicker off and on randomly while sitting still and driving, it shows on my instrument panel switching from auto mode and off randomly I looked up the problem on a couple forums and hundreds of people have had this problem please make this a recall before some hits a child or a car in the street cause the dealerships are not trying to work on it some people said by replacing the turn signal handle it fixed the problem but it needs to be a recall fix not a owner fix if this many people are having a problem ( I found as video on youtube which is the exact problem every one is having https://youtu.be/wyamrudmtqg)
At times the vechicle surges forward when close to another vechicle when in cruise control. Heads lights have turn off, on, automatic, low with out any human interaction. Navagation screen went completely blank
The driver side front turn signal intermittently inoperable. When under warrantee, had dealership repair 5-6 times without success. They changed bulbs and both electrical harnesses. Problem still exists. Took the car into a different dealer and they stated that the left and right sockets burned internal to headlight assembly. This has occurred from early on and continues today. On two occasions at night the entire headlights shut off and I can only assume it is related to the burned internal sockets as well
My vehicle showed solid check engine light while I was on 101 freeway and after exiting to city road I could park and read the error code "p0880 power input to TCM", I reported the issue to hyundai dealer and they diagnosed the issue as internal TCM defect. Dealer replaced the TCM but that couldn't fix the problem. And they just released the car as is. After a short while my car had become unable to reverse, and when set the gear to reverse, my car moves forward to make a very life threatening. I called hyundai corporate office but they didn't help. Now, I cannot drive my car because it is unsafe and because because I'm not a mechanic to diagnose the problem while the dealer and the corporate don't help. I found out that the model of my car is a subject to recall for gear problem which is exactly what I face now. It seems that both of the dealer and the corporate office are aware of the issue in this particular model but they did not even mentioned it to me until I found it by myself. A car like that is unsafe for me to drive because it runs forward only even when the gear is reverse and if stops I cannot even push it backwards. A car with this defect is dangerous for my community. Please help to force that company either replace the car for me, repurchase or repair it to full operational status..
The federal safety agency campaign number 16v575000 - my hyundai is experiencing the exact same symptoms that is portrayed in the campaign number I have listed. I have taken it to a hyundai dealership multiple times and have been told that they are unaware of what the issue is or have "attempted" to fix the issue yet it still occurs. Now, because I have just surpassed my warranty, the hyundai dealership is making me pay for all diagnostics and fixes. My VIN, however, does not show that this was a part of this recall. All of my warning indicators illuminate. My steering becomes tight. My backup camera will not work. And my speedometer and tachometer will glitch and not accurately display my speed or rpms. All indicators inside the lcd screen will show me that I have a malfunction. This includes my passenger seat belt, my lane keep assistance, my autonomous emergency braking, my tire pressure, my engine light, as well as my blinkers not properly illuminating or making any sound when turned on. This will occur from time to time and is not always constant. It will also occur at random, whether I am driving, stationary, or if I have just turned my car on for the first time of the day. I have videos and pictures of these events occurring.
During start-up while stationary, car randomly experienced a full loss of electrical power rendering the whole car inoperable and requiring a tow truck. Upon tow truck arriving at destination, car was running. Highly unsafe. Occurred on 7/2/2018 and 7/19/2018 to date.
Tl* the contact owns a 2015 hyundai genesis. While driving approximately 35 MPH, the contact experienced a loss of steering and brake functionality. Various warning indicators illuminated on the instrument panel. The contact was able to move the vehicle to the side of the road with an excessive amount of effort. The vehicle operated normally after it was restarted. Stevens creek hyundai (4425 stevens creek blvd, santa clara, ca) diagnosed that a rodent had eaten the wiring in the vehicle and it would need to be replaced. The contact stated that this was the second occurrence of the same failure. Upon research,the contact found that the vehicle used soy coated wiring. The manufacturer was notified of the failure. The failure mileage was 14,837.
On june 2, 2017, I was attempting to park my vehicle in a parking stall at a minimum speed of 5-8 MPH. Suddenly, the engine revved up, instrument panel flashed and radio changed stations. When trying to brake the car, the brakes did not engage and I subsequently hit a wall. The airbags did not deploy. When the ealer came to get the car, the individual picking up the car indicated something was wrong with the breaking mechanism. However, the dealer and manufacturer says nothing was wrong with the car but won't provide the details of the report.
I was attempting to make a left turn into traffic when several dashboard indicators went off and the power steering shut down. My family and I were almost hit by on coming traffic! In seconds I was faced with having to turn off and restart the vehicle in order to get it to work correctly and get out of the road. Got home and parked it over night and the next day the same thing happened again with steering and instrument cluster. I absolutely do not feel safe in this vehicle! 2015 genesis 5.0
Electronic gremlins periodically hit. -at random times the front or rear sensors don't "see" objects. I have kissed bumpers with another car when neither of us saw the other, and my genesis failed to see. It's allowed me on at least two occasions to pull too close to objects in front. -worse, there are random episodes where the adaptive cruise control fails to see traffic in front of it. Numerous times we have narrowly missed collisions when we had to quickly and forcefully apply brakes. I've experienced this as has my wife and more importantly clients! -the self-retracting mirrors frequently to not work properly and we have to manually override.
