This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering lighting on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report two distinct lighting issues on the 2012 Hyundai Genesis.
The first is a turn-signal control problem: the convenience three-blink feature cannot be customized to one or two blinks, and the turn signal cannot be immediately cancelled once activated. It continues blinking three times regardless of stalk position.
The second—and far more widespread—involves headlights turning off or flickering when the turn signal is activated or the stalk is manipulated. Owners describe outages lasting 1–5 seconds, occurring both while driving and stationary. The problem happens almost always when the headlight switch is in the "ON" position and rarely or never when set to "AUTO." Many note touching or moving the turn signal stalk will restore lights. One owner reports that activating turn signals sometimes triggers high-beam engagement instead of low-beam shutdown. The failure appears to occur at various mileages, from 46,000 miles onward, and has escalated in frequency for some owners over time.
A separate tail-light concern involves condensation or water filling the tail-light assemblies around 60,000 miles, often after warranty expires. Owners note this is reported as "very common" on Genesis forums.
Dealer attempts to repair have included computer-chip replacement, multi-function switch replacement, and turn-signal stalk replacement. Many dealers refuse repair citing inability to replicate the issue on demand. Some owners have restricted night driving due to safety concerns.

Failure modes owners describe
Turn-Signal Three-Blink Feature Cannot Be Customized
The convenience three-blink turn-signal feature activates with no option to select one, two, or three blinks. Once activated, the turn signal cannot be immediately cancelled and continues blinking three times even when the feature is in lock position or the driver attempts to cancel it.
When: 600 miles (failure detected); 8,900 miles (reported)
Symptoms owners cite: Turn signal blinks exactly three times with no customization option; No way to manually cancel turn signal immediately; Feature does not respond to lock position or cancellation attempts; 1.8 second activation duration too long and does not work properly
Headlights Turn Off or Flicker When Turn Signal Activated
Headlights turn off or flicker for 1–5 seconds when the turn signal is activated or the turn-signal stalk is moved or tapped. The problem occurs randomly, often multiple times per week, in both moving and stationary vehicles. Touching or moving the stalk usually restores lights. Problem happens in 'ON' mode only, not 'AUTO' mode.
When: 46,000 miles and above; owners report onset from 3 years of ownership onward; problem escalating in frequency over time
Symptoms owners cite: Headlights go off for 1–5 seconds when turn signal is activated; Headlights flicker on and off when turn signal is engaged; Lightly touching or tapping the turn-signal stalk causes flicker or lights to turn off; Occurs when turning left, right, or when steering wheel is turned; Problem happens both while driving and while stationary; Touching or moving stalk usually restores lights; High-beam lights may turn on inadvertently instead of low beams turning off; Problem occurs almost exclusively when headlight switch is in 'ON' position, not 'AUTO'; Difficult to replicate on demand at dealership
Repairs/costs cited: First-time repair: computer chip replacement. Second-time repair (same failure recurring): multi-function switch replacement (no-charge under warranty). Some owners report turn-signal stalk replacement under warranty.
Recalls/TSBs owners mention: Some turn-signal stalk replacements performed under warranty. Dealers unable or unwilling to repair due to inability to duplicate issue on demand.
Tail-Light Water or Condensation Intrusion
Water and condensation accumulate inside tail-light assemblies, causing fogging or moisture buildup. Problem reoccurs after warranty expires, even in lights previously replaced under warranty. Owners report this as a widespread and common problem in Genesis forums.
When: Around 60,000 miles; recurs after warranty expiration
Symptoms owners cite: Water or condensation fills tail-light assemblies; Fogging or moisture visible inside tail lights
Repairs/costs cited: One replacement performed under warranty; problem recurred at 60,000 miles when warranty no longer covered it.
Recalls/TSBs owners mention: Covered under original warranty; owners bear cost for repairs after warranty expires.

What owners are reporting 1 most recent
While driving at night with headlights set to on used left turn signal and headlights briefly went out. Since then have had approximately 3 or 4 further incidents like this. I believe at least one incident occurred when steering wheel was turned but turn signal not used (was going around curve). Outage lasts for just about a second. *tr

Common questions
How serious is the lighting problem on the 2012 Hyundai Genesis?
It's a documented issue but not catastrophic. 17 complaints have been filed. Repairs average $250 and most owners catch it before it causes a breakdown.
At what mileage does the lighting typically fail?
Across the 15 complaints that reported odometer mileage, most lighting failures cluster between 22,245 and 58,000 miles, with the median around 46,000. A quarter of owners report trouble before 22,245; a quarter make it past 58,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $250 for lighting repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to lighting?
No active recalls currently cover lighting issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
