What stands out
Of the 5 model years of Hyundai Genesis we track for lighting problems, this one carries the most owner complaints on file — 30.
Owners have filed 30 lighting complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
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.

full bulletin at NHTSA ↗Hyundai is extending the multifunction switch assembly warranty to 15 years with unlimited miles from the date of original retail delivery or date of first use (whichever occurs first). A service procedure is provided to replace the multifunction switch assembly. Certain vehicles may exhibit intermittent headlight flickering while driving with light switch on the AUTO light mode. Refer to the warranty and service parts information outlined in the TSB whenever the multifunction switch assembly replacement is required.

The failure pattern owners describe
The 2015 Hyundai Genesis has a well-documented lighting defect pattern across 30 complaints. The most frequent failure is the front turn signal bulb (part 2357), which serves dual duty as the daytime running light and turn signal. Owners report replacing these bulbs 2–7 times per year, sometimes within weeks of installation, despite using OEM bulbs. The bulb socket shows browning from overheating. Dealers and Hyundai acknowledge the issue is common but offer no permanent solution beyond repeated bulb replacement; LED replacements don't work because the vehicle won't recognize them.
The second major defect involves headlights cycling off or flickering when the turn signal is engaged, even in AUTO mode. The dashboard display simultaneously cycles between AUTO and DRL OFF. This occurs unpredictably at all speeds and road conditions, sometimes multiple times in a single 30-minute drive. At night on unlit roads, the vehicle goes completely dark—a serious safety hazard.
A third failure mode shows complete headlight shutdown while driving, sometimes accompanied by all interior lights going dark. These failures are intermittent and cannot be reliably reproduced in a service bay, which dealers use to deny warranty work.
Additionally, the multifunction stalk's light control knob is extremely sensitive; engaging the turn signal or even touching the stalk can unintentionally cycle the lights through modes. One tail light shows water ingress causing complete failure of both tail and license plate lights.

Failure modes owners describe
Turn signal bulbs burning out prematurely
Front turn signal bulbs (part 2357) fail repeatedly, sometimes within weeks or months. Design combines DRL and turn signal into one bulb with shared filament, causing excessive heat stress. Owners report replacing bulbs 2–7 times per year despite using OEM bulbs. LED replacements are not compatible—vehicle doesn't recognize them. Dealer and Hyundai acknowledge the pattern but offer no permanent fix.
When: Recurring throughout ownership; first failures reported within months of purchase
Symptoms owners cite: Bulb fails without warning; Hyperflashing turn signal (rapid flashing) indicates burnout; Bulb socket shows browning/discoloration from overheating; Replacement bulbs fail again shortly after installation
Repairs/costs cited: Repeated bulb replacement; some dealers replaced harness at no cost under warranty; one estimate $1,100 for entire headlight assembly replacement. Owners resort to aftermarket LED conversions.
Recalls/TSBs owners mention: Dealer confirmed issue is common; advised OEM bulbs only. One owner reports dealer acknowledged multi-function switch as root cause. Hyundai has not issued recall or TSB; Canada market 2015 Genesis uses different eyebrow DRL design, avoiding this failure.
Headlights cycling off/on when turn signal is used
Headlights flicker, dim, or shut off completely for 3–5 seconds when the turn signal stalk is engaged or disengaged, even in AUTO mode. The dashboard display simultaneously cycles between AUTO and DRL OFF or other modes. This occurs unpredictably but more often when turn signal is used. Occurs at all speeds and road conditions.
When: Intermittent, occurring multiple times during a single drive or over weeks; can happen from low mileage (11,717) onward
Symptoms owners cite: Headlights turn off or flicker when turn signal activated; Instrument cluster lights shut off simultaneously; Dashboard light-mode indicator cycles between AUTO and DRL OFF; Vehicle goes completely dark at night, creating safety hazard; Occurs with full, semi, or even just pushing against stalk without full engagement
Repairs/costs cited: Dealer unable to duplicate in most cases and refuses warranty repair citing inability to replicate. One complaint notes headlight wire harness was melting and was replaced.
Recalls/TSBs owners mention: Multi-function switch identified as root cause in at least one case per owner report, acknowledged by dealership to Hyundai. Manufacturer has not issued recall. Dealers typically deny warranty work due to inability to replicate issue in service bay.
Headlights shutting off completely while driving
All headlights turn off without warning while driving day or night, sometimes accompanied by instrument panel and interior lights going dark. Vehicle becomes completely dark on unlit roads at highway speeds. Failures occur randomly and unpredictably, sometimes multiple times within 30 minutes of driving.
When: Intermittent; reported occurring at least 6 occasions in one case, once recorded at 40 mph, once at highway speeds on rural roads
Symptoms owners cite: Complete headlight failure without warning; All exterior and interior lights shut off simultaneously; Lights may flicker and cycle before coming back on; Occurs at all speeds and road conditions (highway, city streets, parking lot, stop lights)
Repairs/costs cited: Dealer was unable to duplicate failure during diagnostic visit; vehicle not repaired.
Recalls/TSBs owners mention: One owner reports contacting Hyundai over 60 times with no response or corrective action. Multi-function switch suspected as cause per owner report of dealership-Hyundai acknowledgment.
Right headlight bulb failing repeatedly
Single right headlight bulb burns out repeatedly despite replacement. Service department performed bulb replacement, but bulb failed the very next day. Technician temporarily resolved issue by jiggling/adjusting connection, indicating loose or intermittent electrical connection rather than bulb failure. Owner alleges unprofessional repair approach.
When: July–September 2020; bulb failed again within 24 hours of initial replacement, and again within 2 months
Symptoms owners cite: Right headlight bulb goes out while driving; Bulb fails again immediately after replacement; Temporary resolution by adjusting/wiggling connection
Repairs/costs cited: Bulb replaced July 6, 2020; failed July 7. Service estimate for permanent fix: $130 parts plus labor (not completed per narrative).
Turn signal bulb failure with intermittent socket/harness issue
Turn signal bulbs fail and sometimes new bulbs do not light despite proper installation. Wiggling harness or adjusting bulb seating may temporarily restore function, suggesting loose connector or corroded socket rather than bulb defect. Bulb filaments appear visually intact but circuit is not complete.
When: Recurring; described as ongoing problem with no mileage specifics provided
Symptoms owners cite: Bulb fails to light despite replacement with new bulb; Bulb appears visually good with both filaments intact; Jiggling wires or reseating bulb temporarily restores function; Issue recurs after days or weeks; New bulb sometimes works, sometimes does not
Repairs/costs cited: Harness replacement recommended by dealer in some cases; one owner replaced harness three times under warranty before dealer suggested entire headlight assembly replacement.
Multifunction switch sensitivity causing unintended light mode changes
The rotary/sliding light control on the multifunction stalk is extremely sensitive. Engaging the turn signal or even touching the stalk inadvertently rotates the light mode knob, cycling through AUTO, DRL, ON, and OFF modes without driver intent. One technician at a Kia dealer confirmed hearing similar complaints about knob sensitivity.
When: Recurring throughout ownership; no specific mileage provided
Symptoms owners cite: Light mode control changes when using turn signal; Headlights cycle through modes unintentionally; Occurs when blinker is engaged or when driver pushes against stalk; Light knob described as extremely sensitive
Repairs/costs cited: Not inspected or repaired by manufacturer per complaint.
Tail light water leakage and corrosion
Left tail light assembly allows water ingress, causing corrosion and complete electrical failure of both tail light and license plate light.
When: Timing not specified
Symptoms owners cite: Water leaking into tail light housing; Tail light stops working; License plate light stops working
Poor low-beam headlight illumination
Headlights provide insufficient illumination at night in standard (non-high-beam) mode, limiting safe visibility distance.
When: Ongoing issue; no mileage specified
Symptoms owners cite: Unable to see safe distance ahead at night without brights

What owners are reporting 2 most recent
The headlights, whether in auto-mode or on-mode, will randomly turn off by themselves for a couple seconds, then cycle quickly back on and off, before turning back on after a few seconds. Within a 30min drive this typically will happen at least once. It is speed independent; it will occur at highway speeds, during rest at a stop light, driving through a parking lot, through dark twisting forest…
When my headlights are in the "auto" position and I engage my turn signals my headlights will flicker and the lcd screen on my dash switches between "auto" and "drl off" which causes my lights to turn off for a couple seconds. This usually happens when I'm in motion and when the turning stalk is engaged, either fully or semi, or even sometimes when I just push up against the stalk without…
