DIM HEADLIGHTS ARE VERY WEAK, NOT AIMED CORRECTLY OR POOR DESIGN. NOT ENOUGH CANDLE POWER TO SEE DIVIDING LINES ON HIGHWAY. WITH BRIGHT LIGHTS THINGS ARE GOOD.

Common questions
How serious is the lighting problem on the 2018 Hyundai Sonata?
It's a documented issue but not catastrophic. 18 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?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
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.
