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. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.

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
The 2012 Elantra has a systematic lighting package problem that affects multiple systems. The DRL system doesn't engage automatically at engine start as advertised; owners must manually turn on parking lights to activate DRLs, which also illuminates the amber side markers and rear tail lights—a design that masks turn and stop signals. When DRLs are on, the gauge cluster dims to night level, making the odometer unreadable during the day.
Brake light failures are frequent and varied. Some owners find rear brake lights stuck on permanently, even with the engine off, traced to a broken brake pedal stopper pad. Others report brake lights failing to illuminate when the pedal is depressed, sometimes triggered by road bumps. Multiple owners report needing eight or more brake light bulb replacements within six months, along with repeated headlight failures. One owner replaced both high beams simultaneously after 60,000 miles.
Dashboard warning lights—likely airbag or check-engine indicators—cycle on and off repeatedly over months, returning even after mechanic service. Dealers have offered electrical diagnostics for $125 but declined recalls, noting that some brake light issues affecting 2013 models carry recalls not extended to 2012 Elantras. Part store staff have indicated an underlying electrical problem rather than simple bulb failure.

Failure modes owners describe
DRL system design—lights engage via parking lights instead of automatically
Owners report that daytime running lights (DRLs) do not activate automatically when the engine starts, contrary to the Monroney sticker claim and NHTSA/IIHS definitions. Instead, parking lights must be manually engaged to turn on the DRLs. When active, this also illuminates amber side parking lights and rear tail lights, which can mask turn and stop signals. Additionally, interior gauge lighting dims to night-driving level, reducing readability during daytime.
When: Present from purchase or early ownership
Symptoms owners cite: DRL does not engage automatically when vehicle starts; Parking lights must be manually turned on to activate DRL; Amber side parking lights and rear tail lights illuminate together with DRL; Gauge cluster dims to night level when DRL is active; Difficulty reading odometer/mileage display during daytime; Turn and stop signals masked by illuminated parking and tail lights
Repairs/costs cited: Hyundai dealerships confirmed this is 'a new design' and stated no fix is available.
Brake lights remain illuminated when vehicle is parked or off
Brake light switch remains stuck in an activated state, causing rear brake lights to stay on continuously even when the vehicle is parked and the engine is shut off. One owner identified the brake pedal stopper pad as the culprit after it broke and fell off, preventing the brake light switch from deactivating. A 2013 model year recall exists for this issue, but not for 2012 models.
When: 40,000–104,000 miles
Symptoms owners cite: Rear brake lights illuminated continuously while parked; Rear brake lights remain on after engine shut off; Brake lights stay on even when not applying brakes; No warning indicator for the condition
Repairs/costs cited: Brake pedal stopper pad replacement; owner improvised temporary fix with cardboard tape
Recalls/TSBs owners mention: 2013 model year recall exists (not extended to 2012); recall reference number 16138484 issued but no further assistance provided
Exterior light bulbs fail repeatedly in short intervals
Multiple light bulbs across the vehicle fail prematurely and repeatedly, lasting less than one month after replacement. Failures include brake lights (8+ replacements in six months), headlights (4 replacements), and high beams (both failed simultaneously). Problem frequency increases over time. Parts store employee suggested an underlying electrical problem; dealership diagnostics offered for $125 fee.
When: Around 60,000 miles; worsening from late 2017 onward
Symptoms owners cite: Brake lights fail repeatedly; Headlights fail repeatedly; High beams fail simultaneously; Bulb lifespan less than one month; Lights may work in AUTO position but not in ON position, or vice versa; All exterior lights may go out completely without warning
Repairs/costs cited: Bulb replacements (8+ brake light bulbs, 4 headlight bulbs, multiple high-beam bulbs); parts store staff indicate electrical system problem
Brake lights fail to illuminate when brake pedal is depressed
Brake lights do not illuminate when the driver applies the brakes, even though the vehicle is running and the brake pedal is being depressed. Owners report this occurs while driving at highway speeds. Stop lamp switch failure has been identified as the root cause in at least one case. A recall exists for prior model years but has not been extended to 2012.
When: Approximately 40,000–114,000 miles
Symptoms owners cite: Brake lights do not illuminate when brake pedal is depressed; Failure occurs while driving at speed; Failure is intermittent (recurring 4–5 times within a year on one vehicle); No warning indicator illuminates; Brake lights fail to work on multiple separate occasions
Repairs/costs cited: Stop lamp switch replacement indicated; some fuses checked and confirmed functional
Recalls/TSBs owners mention: Recall exists for prior model years but not extended to 2012; manufacturer did not provide assistance in reported cases
Dashboard warning light (airbag/yellow light) cycles on and off repeatedly
A yellow warning light (likely the airbag or check-engine indicator) illuminates and then goes off for a period of time, only to reappear. The cycle repeats over months. Mechanic visits have not permanently resolved the issue, and the light returns after 1–2 months of being off.
When: Intermittent; recurring over past year
Symptoms owners cite: Yellow warning light illuminates; Light extinguishes after mechanic visit for 1–2 months; Light reappears; Cycle repeats
Repairs/costs cited: Mechanic service attempted but issue not permanently corrected
Brake lights fail after minor road bumps
Brake lights go out when the vehicle hits a small bump in the road, and the airbag warning light illuminates simultaneously. The failure appears to be triggered by impact rather than by a persistent electrical fault, suggesting a sensor or connection sensitivity issue.
When: After one year and three months of ownership
Symptoms owners cite: Brake lights go out after hitting a small bump; Airbag warning light illuminates; Failure triggered by minor road impact

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?
