Typical electrical symptoms owners report

  • Brake lights stay illuminated on one or both sides even when the brake pedal is not pressed, sometimes tied to headlight use.
  • A battery discharge warning appears on the dashboard display if the driver stays in the parked, powered-off car without exiting right away.
  • Some vehicles lack a passive engine immobilizer, allowing the engine to be started with a USB cord, prompting a free anti-theft software update from Hyundai.
  • Warning lights for lane keeping, blind spot, ABS, autohold, and forward collision systems turn on and will not reset, misleading drivers into thinking a crash is imminent.
  • A rear-view or reference camera/display loses power intermittently, requiring repeated dealer visits without a diagnosed cause.
  • A flashing check engine light has triggered limp mode multiple times, occurring alongside replacement of a knock sensor, catalytic converter, and spark plug coil.
