Approximately once every 500 - 2000 miles (maybe more frequently this year), my car suddenly begins to accelerate hard. This happens even if my foot is completely off the gas pedal. Usually, before the problem becomes severe, there are a few minutes in which I suspect the car is sometimes lurching forward, or losing some ability to accelerate. Then the problem worsens til the car is almost undriveable... it speeds up, I slow it down with the brakes, I release the brakes, the car speeds up, I slow it down with the brakes again, and so on.

The passenger side headlight has significant condensation inside the housing. The car is slightly over five years old, with 40,000 miles It was rarely driven the first year due to the pandemic. I have seen there is a TSB regarding the headlights, but clearly this is a far more significant issue than Hyundai is letting on. I was getting a warning on the dash but that has stopped yet the headlight is still covered in heavy condensation.

Windshield wipers intermittently malfunction in the intermittent setting. The wipers stop at random locations in the middle of the windshield, pause, move a short distance, stop again, and behave erratically. This can obstruct the driver’s forward visibility. The problem occurs without snow, ice, or an obstruction on the windshield. A previous NHTSA complaint concerning a 2021 Hyundai Elantra describes essentially the same failure: wipers stopping midway and obstructing the driver’s view (NHTSA complaint 11685493/complaint record). A separate 2026 complaint involving a 2021 Elantra reported intermittent wiper operation along with other multifunction-switch functions, and the dealer diagnosed
