2015 Hyundai Genesis: headlights failing or too dim

Filed Apr 25, 2026 · Electrical · TX

I took my car in to Tomball Hyundai due to intermittent failure of the headlight switch and the wiper switch when both of these features are set to the ‘Auto’ setting. These are very intermittent issues, but as luck would have it, it was sprinkling on my drive to the dealership on [XXX] and I was able to capture the wiper issue via video on my phone which I shared with the service advisor. Then, fortunately, 2 days later, the service technician was able to verify the intermittent headlight failure. I was aware of a TSB (TXXH) which is meant to address this problem, however, Hyundai issued a superseded TSB a few months after the original, in which they deleted the wiper switch from the service. The 2015 Genesis multifunction switch is sold as a single integrated unit (P/N 93400-3M031), but Hyundai’s TSB 20-BE-009H-1 mandates a "hack" repair that leaves the failing wiper switch in place. It is my assertion that when Hyundai settled a class action lawsuit regarding this switch, they agreed to extend the warranty on the entirety of the Multifunction Switch Assembly (NOT just the Headlight portion of the switch) for 15 years and Unlimited mileage. The Hyundai National Customer Service Case Manager (Roobika, 714‑912‑2118 National Consumer Affairs) told me that my request of having the complete switch replaced was denied due to the vehicle being out of warranty and having 73,481 miles. *to be clear here - Hyundai HAS agreed to replace the Headlight switch only - their denial centers on the Wiper switch. Eager to find a solution, I suggested that I could cost-share. This was declined as well. I was only given the option of buying the whole switch myself and allowing them to provide the labor to install it. Furthermore, It is technically illogical to perform a warranty repair by disassembling an integrated unit to replace one half while ignoring the failure of the other half—especially when the labor required to access the part is identical.

The headlights intermittently turn off when driving at night. Usually it’s related to using the turn signal, but sometimes it does it completely on its own. Puts others and self at risk as driving down remote roads in the dark and lights cutting out for several seconds can be deadly. Dealer claims they cannot replicate after having the car for nearly 13 weeks total. (7 weeks first time, did not fix issue, 6 weeks second time, “couldn’t replicate”) Unknown. The dash will flash the headlight menu but no other warnings.

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.

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

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.

There is an electrical issue that could malfunction internally and cause an electrical short, potentially resulting in an engine compartment fire. The front bulb for the daylight running lamps/ lane changing blinker has been consistently stopped working and/or blown out. The dealer where I purchased the vehicle has worked on the vehicle a minimum of six times, changing the electrical harnesses (among other things) with no success. When looking up this issue on the internet, other owners have reported this problem with the 2015 model and older Hyundai Genesis. Hyundai did changed the daylight running lights in 2016. On a few occasions (3 times), the headlights turned off at night which may or may not be related. I have another appointment in ten days to address the situation once again.

The auto light position turns from automatic to fully off when driving randomly. This is a big safety hazard as you lose function of headlights temporarily.

While driving at night or during day, multifunction switch that controls headlamps will, without interaction, flip the lights from auto to off. This leads to either the drls blinking like I have an emergency, or the headlamps turning off while I'm driving down an unlit highway at highway speeds. It's extremely dangerous and needs a recall...not a warranty extension. Particularly when the servicing dealers refuse to replace under said warranty because "they cannot replicate the issue".

Headlights flicker while cycling through options on dashboard controls, typically ending on the off selection. Occurs after using the turn signal.
