⚠️ VEHICLE troubleshooting

Guides to fix issues if something isn’t working.

Troubleshooting Infotainment System / Frozen Screen



  • Press and hold the Power button for 10 seconds to restart the system.
  • Check if your system needs a software update (available via Hyundai’s website).
  • If the screen is black, check the fuse box under the dashboard.

Bluetooth Not Connecting

  • Ensure Bluetooth is enabled on your phone.
  • Restart the infotainment system and try reconnecting.
  • If connection fails, remove the pairing and try again.
  • Avoid metallic window tint, which can interfere with Bluetooth signals.

CarPlay / Android Auto Not Working

Basic Fixes

  • Restart your phone & car’s infotainment system (hold the power button for 10+ seconds).
  • Make sure your phone's software is up to date.
  • Check if your Tucson supports wired or wireless CarPlay/Android Auto.

If Using a USB Cable

  • Use the front USB port (rear ports do NOT support CarPlay/Android Auto).
  • Try a different high-quality cable (cheap or damaged cables can cause issues).
  • Allow permissions on your phone (iPhone: Settings > General > CarPlay, Android: Android Auto app > Connected cars).

If Using Wireless Connection

  • Enable Bluetooth & Wi-Fi on your phone.
  • Forget and re-pair the Hyundai Bluetooth connection.
  • Reconnect in infotainment settings (Setup > Device Connections > Add New Device).

If It Still Doesn’t Work

  • Check Hyundai’s website for infotainment software updates.
  • Try another phone to see if the issue is with your device.
  • Visit a Hyundai dealer if the issue persists.

Lane Keep Assist Not Functioning

Basic Fixes

  • Make sure LKA is turned ON:
  • Press the Lane Assist button on the steering wheel.

A white or green lane icon should appear on the dashboard.

White = Standby Mode (not active yet)

Green = Active Mode (LKA is working)

  • Check your speed:

LKA only works between 40–120 mph.

Below 40 mph, it switches to Lane Departure Warning (LDW) only.

  • Ensure clear lane markings:

LKA requires visible lane lines on both sides.

Bad weather, faded road markings, or glare can interfere with detection.

If Lane Keep Assist Still Doesn’t Work

Check if Forward-Facing Camera is Blocked:

  • The camera is located behind the rearview mirror.
  • Clean the windshield area in front of the camera (dust, fog, or ice can block it).
  • Restart the vehicle:
  • Turn the car off and on and see if LKA reactivates.

Check for system errors:

  • If you see a warning light or message, scan for error codes using an OBD-II scanner or visit a Hyundai dealer.

Power Liftgate Not Opening

  • Car must be in "Park" (P) for the liftgate to open.
  • Enable power liftgate in settings: Setup > Vehicle > Door > Power Liftgate.

Try different methods:

  • Smart key button (hold for 3+ sec).
  • Inside button near the driver’s seat.
  • Outside button on the liftgate handle.

If It Still Won’t Open:

  • Check for a locked liftgate switch inside the trunk.
  • Manually reset:

Turn off the car.

Manually open the liftgate using the emergency release.

  • Close it firmly, restart the car, and try again.
  • Check for obstructions (snow, ice, cargo).
  • Inspect fuse (under dashboard) or disconnect battery for 5 minutes.
  • Visit a Hyundai dealer if the issue persists.

Parking Brake Won’t Release

  • Check if your seatbelt is fastened – Some models require it.
  • Press the brake pedal firmly while trying to release the parking brake.
  • Ensure the car is in "ON" or "RUN" mode – The electronic parking brake (EPB) won’t release if the car is off.

Try both methods:

  • Push the EPB switch down while pressing the brake pedal.
  • Manually drive forward slightly to see if Auto Hold releases it.
