The failure pattern owners describe
Owners report multiple lighting failures across the 2017 Elantra. Headlights cutting out while driving, sometimes triggered by turning or switching beam modes, pose the biggest safety concern—lights go dark for seconds before returning on their own. Several owners cite headlight bulbs burning out repeatedly every few months, with one owner replacing the same bulb three times in 2020 alone. Lights turning on by themselves when the car is parked (even with the key fob and remote lock engaged) happen intermittently. One owner describes the same incident repeating within 24 hours around 11 p.m. Brake lights need replacement multiple times, with one owner mentioning a known faulty harness issue discussed widely in Hyundai forums. A parking light (center park lamp, passenger side) doesn't work due to missing power feed wire in the headlight assembly, though the driver side has the wire. Owners also report intermittent warning messages for Automatic Emergency Braking, Lane Departure Warning, and Automatic High Beam systems cycling on and off while driving. One owner had lights flicker on and off in auto mode while driving. Dashboard warning lights for check engine, check brake light, and check oil lamp either malfunction, fail to appear, or display incorrectly.

Failure modes owners describe
Headlights cutting out while driving
Headlights go completely dark during operation, usually when turning or switching between low and high beams, then return on their own after several seconds. Occurs without warning or diagnostic messages.
When: While driving at night or in dark conditions; intermittently, sometimes when making turns or switching beam modes
Symptoms owners cite: Complete loss of headlight illumination; Lights return on automatically after seconds; Occurs when switching low/high beams or turning right; No warning lights or messages displayed
Headlight bulbs burning out prematurely
Headlight bulbs fail frequently and require replacement every 3–6 months, far more often than normal. Owner reports replacing the same bulb multiple times within a single year.
When: 3–6 month intervals; one owner replaced the same bulb 3 times in 2020
Symptoms owners cite: Bulbs burn out repeatedly; Both headlights may go out at the same time; Low beam headlights fail; Check engine light appears when headlights fail
Repairs/costs cited: Bulb replacement required multiple times per year
Lights turning on by themselves when parked
Headlights and tail lights activate on their own while the vehicle is parked and locked. Occurs unpredictably and cannot be controlled remotely; requires physically entering the car and turning it on and off to stop the lights.
When: While parked; incidents reported around 11 p.m., occurring on consecutive nights
Symptoms owners cite: All exterior lights turn on without input; Remote key fob will not turn off lights; Lights turn off only after physically starting and stopping the engine; Lights turn back on by themselves after turning off
Brake lights requiring frequent replacement
Brake lights fail repeatedly and need replacement multiple times. One owner cites a known faulty harness issue widely discussed in Hyundai owner forums as the underlying cause of chronic brake light failures.
When: Multiple replacements over 8 years of ownership
Symptoms owners cite: Brake lights go out; Bulbs fail multiple times in multiple areas; Check brake light warning appears
Repairs/costs cited: Known faulty harness issues cited by owner and service technicians
Passenger-side park light not working
The center park light on the passenger side does not illuminate. Inspection reveals the passenger-side headlight assembly lacks a power feed wire for the park light circuit, while the driver-side assembly has the wire installed.
When: Present from manufacture or early ownership
Symptoms owners cite: Passenger-side park lamp in center does not work; Missing power feed wire in passenger headlight assembly; Driver-side park lamp works normally
Repairs/costs cited: Missing power feed wire in passenger-side headlight assembly on original and replacement units
Intermittent warnings for driver-assistance systems

When: Intermittently while driving; may or may not begin at startup; occurs at any speed or while idling
Symptoms owners cite: Intermittent warning lights for AEB, LDW, and AHB systems; All three warnings appear together; Warnings cycle on and off over hours or minutes; No consistent pattern or trigger identified
Lights turning on and off randomly in auto mode

At what mileage does the lighting typically fail?
Based on the 13 complaints filed, lighting issues most often appear around 64,700 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
