The 2013 Elantra's lighting system is the source of persistent complaints spanning the entire electrical spectrum.
DRL advertising versus reality forms the core complaint: the window sticker claims daytime running lights, but the system requires owners to manually turn on parking lights—which simultaneously activates rear taillights, front and rear parking lamps, and license plate lights. This setup is illegal in states that prohibit daytime parking-light operation and drains fuel economy and battery life. Owners repeatedly contact Hyundai and dealers, only to be told this is "characteristic of the model" with no fix available.
Brake lights fail chronically, burning out every 3–6 months or in groups of three at once. Owners report being pulled over or warned by other drivers about dead lights, and they keep spare bulbs in the car. Even after wiring harness replacement, bulbs continue failing.
Tail, headlight, and parking-light bulbs follow the same pattern—premature burnout requiring constant replacement throughout ownership, sometimes within weeks of each other.
Lamp housings physically melt from excessive heat, with internal plastics warping and lens cracks appearing at the seal, yet no safety warning alerts drivers to the damage.
Parking and headlights malfunction erratically—turning on in freezing temperatures while parked, shutting off mid-drive, or flashing uncontrollably. Dealer parts replacement (including the switch inhibitor) has not resolved these failures, and Hyundai customer service cases opened remain unresolved.
Turn signals hyperflash, stick on one direction, or fail when headlights are on, and some tail lights allow water intrusion after rain.
Failure modes owners describe
Daytime Running Lights (DRL) Design Defect
DRL system requires manual activation of parking lights, which simultaneously activates full rear tail lights, front and rear parking lamps, and license plate lights. Vehicles lack true automatic DRL operation. This forces owners to run all exterior lamps during daytime driving, which is illegal in some states, increases fuel consumption, reduces bulb life, and makes brake lights less distinctive during daylight hours.
When: Present from purchase; reported across multiple model years within 2013 production
Symptoms owners cite: Daytime running lights do not activate automatically when engine starts; Parking lights must be manually turned on for DRL to function; All rear and side marker lights illuminate whenever DRL is selected; Dashboard gauge lights automatically dim to nighttime levels when DRL activated during daylight; Owners misled by window sticker advertising 'DRL' as standalone feature
Repairs/costs cited: Dealer and Hyundai confirmed this is characteristic design of non-Limited models; no repair offered. Software change implemented mid-2012 identified as root cause.
Recalls/TSBs owners mention: Hyundai case managers confirmed this is 'characteristic of this model (excluding the Limited models)' with automatic headlamp control. Dealers reported unable or unwilling to resolve.
Brake Light Bulb Failures and Premature Burnout
Brake light bulbs fail repeatedly every 3–6 months or more frequently. Multiple owners report entire sides of brake lights failing simultaneously, requiring repeated replacements. Some bulbs burned out after approximately 6 replacements in under a year. Pattern consistent across multiple complaint reports.
When: Failures reported from 34,000 miles through 199,500 miles; recurring throughout ownership
Symptoms owners cite: Brake light bulbs burn out every 3–6 months; Multiple brake lights fail at the same time (all three brake lights out simultaneously); Bulbs requiring frequent replacement despite correct type per manual; Owners being pulled over or warned by other drivers due to non-functioning brake lights; Bulbs failing even after wiring harness replacement
Repairs/costs cited: Multiple owners replaced bulbs themselves or at shops; some had wiring harness replaced without resolution. Costs cited range from $135 for parts and labor to ongoing out-of-pocket replacement expense.
Recalls/TSBs owners mention: Hyundai informed owners no recall exists despite identical failure patterns to NHTSA recall 16V574000 and 17V769000 (brake-related); one dealer said 'possibly related to brake recall' but vehicle excluded from campaign.
Tail and Parking Light Bulb Failures
Rear tail lights, parking lights, and license plate bulbs fail repeatedly and prematurely. Bulbs burn out every few months; owners report constantly carrying spare bulbs in vehicle. Some bulbs require tapping on the fixture to illuminate.
When: From early ownership through high mileage (59,000 to 100,000+ miles)
Symptoms owners cite: Tail light bulbs burn out and require replacement every few months; Parking light bulbs fail prematurely; License plate light bulbs fail; Bulbs occasionally intermittently loose in sockets, requiring tapping to re-seat; One or several lights out simultaneously on occasion
Repairs/costs cited: Owners replaced bulbs at auto shops and DIY; one owner mentioned $135 total repair cost for multiple bulb replacements.
Recalls/TSBs owners mention: No recalls identified; manufacturer informed owners vehicle out of warranty or declined to assist.
Headlight Bulb Failures and Dimming
Front headlights fail repeatedly or become dimmer than normal. Low-beam headlights appear dimmed during normal driving conditions; some bulbs burn out or sockets become inoperative. Pattern of repeated failures even after bulb replacement.
When: Early ownership reported at 2,000 miles and 12,000 miles; recurring at 90,000 and 100,000 miles
Symptoms owners cite: Low-beam headlights dimmer than normal at 35 mph in low-light conditions; Headlights fail or shut off while driving; Headlights flash off and on without warning; Bulbs require frequent replacement despite correct type; Failure recurs even after bulb and socket replacement by dealer and independent mechanic
Repairs/costs cited: One dealer replaced one inoperative headlight; independent mechanic replaced all headlights but failure recurred. Another owner purchased replacement socket at AutoZone after socket burned out.
Recalls/TSBs owners mention: Manufacturer not informed in most cases; no recalls identified or offered.
Lamp Housing Melting and Physical Damage
Brake light and tail light housings, along with internal lens plastics, melt or overheat due to excessive heat from lamps. Owner identified that internal plastics exceed glass transition temperature. License plate bulb housings also affected.
When: Reported at 38,000 and 57,000 miles; beginning around 34,000 miles for one owner
Symptoms owners cite: Internal plastics in tail lamp housings melt or warp; License plate bulb housing shows melting evidence; Outer tail lamp housings melt or crack; Brake light lens cracked from overheating; Physical damage visible upon inspection or bulb replacement
Repairs/costs cited: License plate bulb houses and outer tail lamp housings replaced due to damage. Repair costs cited as $560 for brake light lens replacement.
Recalls/TSBs owners mention: No safety recall issued despite defect identified. One owner noted no safety mechanism to warn driver of this hazard.
Brake Lights Remaining Illuminated or Stuck On
Brake lights remain illuminated even after brake pedal is released or vehicle is turned off. Some lights remain on continuously, draining battery. Failure related to brake pedal stopper fracture or switch malfunction.
When: Reported at 69,000 miles, 76,244 miles, and 199,500 miles
Symptoms owners cite: Brake lights remain illuminated after depressing and releasing brake pedal; Brake lights remain on after vehicle is turned off; Battery drained due to continuously illuminated lights; Brake pedal stopper fractured, preventing proper switch operation
Repairs/costs cited: Owner removed fuse to shut off brake lights. Dealer identified need to replace brake stopper and switch; one repair recurred after service. Another owner replaced brake light sensor and bulbs at unknown cost.
Recalls/TSBs owners mention: Manufacturer notified in multiple cases; some informed no warranty coverage applied. Dealers noted identical failure to NHTSA campaign 16V574000 but vehicle excluded from recall despite exhibiting same failure.
Turn Signal Malfunction
Turn signals hyperflash, flash continuously after turn completion, remain stuck on one direction, or fail to work properly depending on headlight status. Some signals fail to operate when headlights are on.
When: Reported at 1,100 miles and during ongoing ownership; recurring issues
Symptoms owners cite: Turn signal flashes continuously after completing turn; Turn signal gets stuck flashing in one direction; Turn signal hyperflashes with headlights off; Turn signal fails to work when headlights are on; Left turn signal continues flashing after left turn completed
Repairs/costs cited: Owners did not pursue repair; dealer unable to duplicate failure.
Recalls/TSBs owners mention: Manufacturer informed in at least one case and stated nothing could be done to assist.
Water Intrusion in Tail Light Assemblies
Water enters driver's and passenger's rear tail light assemblies after rain, causing bulbs to become inoperative. Condensation or seal failure allows moisture to collect inside lamp housings.
When: Reported at 38,000 miles
Symptoms owners cite: Water visible inside rear tail light assemblies after rain; Bulbs become inoperative due to water intrusion; Moisture trapped in lamp housing
Repairs/costs cited: Owner replaced light bulbs after water intrusion incident.
Recalls/TSBs owners mention: Dealer informed no recall exists; manufacturer stated vehicle out of warranty.
Headlight Switch or Stalk Malfunction
Headlight control stalk requires manual manipulation to operate properly; lights flash on and off randomly or require hand adjustment to function. Parking lights and headlights turn on or off erratically without user input, particularly in cold temperatures.
When: Temperature-related failures when freezing conditions occur; also reported during normal daytime driving
Symptoms owners cite: Headlights flash off and on without warning while driving at night; Headlights switch malfunctions require manual manipulation; Parking lights turn on while car is parked and turned off (overnight in freezing temperatures); Headlights turn off while car is running and turn signals are used
Codes mentioned: 42700-26500 (switch inhibitor part number)
Repairs/costs cited: Dealer replaced switch inhibitor (part 42700-26500) and car battery; neither corrected the issue. Hyundai customer service case 9687427 opened but no solution provided after weeks with no contact.
Recalls/TSBs owners mention: Hyundai dealership could not reproduce problem during three service visits; parts replaced without resolution. Hyundai customer service case opened but left unresolved.
Bulb Sockets Becoming Loose or Corroded
Rear signal and tail light sockets fail to maintain proper bulb contact, causing lights to become loose and non-functional. Bulbs require manual re-seating to restore operation.
When: Reported from approximately 34,000 miles; ongoing through 57,000 miles
Symptoms owners cite: Rear signal and tail light bulbs frequently become loose in sockets; Bulbs fail to properly function due to poor socket contact; Lights require fixture access to reset bulb contact; Problem occurs at any time, stopped or in motion; Three tail lights and one license plate light have burned out and been replaced
Repairs/costs cited: No repair mentioned; owner managing by re-seating bulbs as needed.
Recalls/TSBs owners mention: No manufacturer response documented.
