⚠️ VEHICLE troubleshooting

Guides to fix issues if something isn’t working.

Troubleshooting Infotainment System / Frozen Screen



1. Soft Reboot:

  • Turn off the car: Turn off the ignition and allow the car to sit for a few minutes.
  • Turn the car back on: Start the car and see if the infotainment system responds. 

2. Hard Reset (If Soft Reboot Fails):

  • Locate the reset button: Some Hyundai models have a small reset button (often a small hole) near the infotainment screen or volume controls.
  • Use a paperclip or similar tool: Carefully insert a small, pointed tool into the reset button hole and hold it down for a few seconds.
  • Allow the system to restart: The screen may turn off and then restart, potentially resolving the issue. 

3. Check for Software Updates:

  • Go to system settings: Navigate to the infotainment system's settings menu.
  • Look for software updates: Check for available updates and follow Hyundai's instructions for installing them. 

4. Other Troubleshooting Steps:

  • Clean the screen:
  • A dirty screen can sometimes cause touch issues. Clean the screen with a microfiber cloth and screen cleaner. 
  • Check radio settings:
  • If the radio is the problem, ensure the correct radio settings are selected and that the car is scanning for stations properly. 


Bluetooth Not Connecting


1. Basic Checks:

  • Power Cycle:
  • Restart both your phone and the car's infotainment system (turn them off and then back on). 
  • Bluetooth Enabled:
  • Ensure Bluetooth is turned on in your phone's settings and that the Tucson's infotainment system is searching for devices. 
  • Check for Compatibility:
  • Make sure your phone is compatible with the Tucson's Bluetooth system. 
  • Check for Interference:
  • Ensure there are no physical objects or other devices causing interference. 

2. Pairing Issues:

  • Forget and Re-Pair:
  • On both your phone and the Tucson's infotainment system, delete the paired device and then try re-pairing. 
  • Check for Passkey:
  • If prompted, ensure you enter the correct passkey (if any) during the pairing process. 
  • Check for "Trust Mode":
  • Some phones might have a "trust mode" that needs to be activated for Bluetooth connections. 

3. Software Updates:

  • Check for Updates: Ensure both your phone and the car's infotainment system have the latest software updates installed. 
  • Update Bluetooth Drivers: Make sure you have the latest Bluetooth drivers installed on your phone. 

4. Advanced Troubleshooting:

  • Reset Infotainment System:
  • If nothing else works, you might need to reset the infotainment system (refer to your Tucson's manual for instructions). 
  • Check for Errors:
  • Look for any error messages on the Tucson's screen that might provide clues about the problem. 


CarPlay / Android Auto Not Working


1. Software Updates:

  • Phone:
  • Ensure your phone's operating system and the CarPlay/Android Auto app are up to date.
  • Car Infotainment:
  • Check for updates to your Tucson's infotainment system through the settings menu. 

2. Connection Type:

  • Wired Connection:
  • Cable: Use a certified, data-transfer capable USB cable. 
  • Port: Ensure the USB port is set to data transfer mode (if applicable). 
  • Try a different cable and port: If possible, test with a different USB cable and/or USB port. 
  • Restart: Restart both your phone and the car's infotainment system. 
  • Wireless Connection:
  • Bluetooth and Wi-Fi: Make sure both Bluetooth and Wi-Fi are enabled on your phone. 
  • Pairing: Ensure your phone is properly paired with the car's system. 
  • Auto-Join: Verify that auto-join is enabled for CarPlay/Android Auto in your phone's settings. 


Lane Keep Assist Not Functioning

1. Check System Status and Activation:

  • Ensure LKA is On:
  • Verify that the LKA system is turned on through the touchscreen or the steering wheel button. 
  • Check the Display:
  • Look for the LKA icon on the instrument cluster. It should appear in white when the system is on and in green when actively engaged. 
  • Verify Lane Markings:
  • The system relies on detecting lane markings. Ensure the road has clear and visible lines. 
  • Check for Warnings:
  • If the system is malfunctioning, a warning message or a yellow indicator light might appear on the cluster. 

2. Potential Issues and Solutions:

  • Windshield Obstructions:
  • Clean the windshield and the camera area behind the rearview mirror, as dirt, grime, or moisture can interfere with the camera's ability to detect lane markings. 
  • Turn Signals:
  • LKA might temporarily deactivate when turn signals are used, so check if the system resumes after the signal is turned off. 
  • Lane Position:
  • Ensure the vehicle is centered in the lane when LKA is activated, as the system might not function optimally if the vehicle is too far from the lane center. 
  • Road Conditions:
  • LKA might not function in adverse weather conditions, such as heavy rain or snow, or on roads with poor lane markings. 
  • Vehicle Stability Control (ESC) or Vehicle Stability Management (VSM):
  • If ESC or VSM is activated, LKA might be temporarily disabled. 


Power Liftgate Not Opening

1. Basic Checks:

  • Parked and Engaged: Make sure the vehicle is in Park (P) and the parking brake is engaged. 
  • Clear Path: Ensure there are no obstructions in the liftgate's path, as the system has obstacle detection. 
  • Smart Key: If using the smart liftgate feature, confirm the smart key is on your person and the vehicle has been locked for at least 15 seconds. 
  • Doors Closed and Locked: Ensure all doors and the hood are closed and locked. 
  • Smart Liftgate Enabled: Verify that the smart liftgate feature is enabled in the vehicle's settings (Setup > Vehicle > Door). 

2. Resetting the Power Liftgate:

  • Simultaneous Button Press: With the vehicle in Park, press and hold the power liftgate open/close button inside the tailgate and the corresponding button outside the vehicle simultaneously until you hear a chime.
  • Manual Closure: Gently close the liftgate manually after the reset. 

3. Smart Liftgate Operation:

  • Proximity: Stand within 3 feet of the rear bumper for more than 3 seconds with the smart key on your person. 
  • Activation: The hazard lights will flash, the chime will sound six times, and the smart liftgate will open. 
  • Stopping the movement: Press either the main control button or the button on the smart key to stop the liftgate movement. 

4. Other Potential Issues:

  • Strut Failure: If the liftgate struts are failing, it can cause the liftgate to not open or close properly. 
  • Obstacle Detection: Manually pushing or pulling the liftgate may activate the obstacle detection feature and stop the power operation. 


Parking Brake Won’t Release

1. Check the EPB Warning Light:

  • Illumination: The EPB warning light should illuminate when the parking brake is engaged and the engine is running.
  • Extinction: Ensure the light turns off when the parking brake is released.
  • Blinking: A blinking light could indicate a potential issue with the EPB system. 

2. Verify Proper Release:

  • Before Driving:
  • Always confirm the parking brake is fully released and the warning light is off before starting to drive. 
  • Automatic Release:
  • On some models, the EPB may automatically release when the vehicle is in motion and the driver's seatbelt is fastened. 

3. Troubleshooting Steps:

  • Check for Obstructions: Ensure nothing is obstructing the EPB switch or cable. 
  • Inspect Cables: Look for any damaged or frayed cables. 
  • Check for Rust or Corrosion: Rust or corrosion can cause the brake to jam or not release properly.  

4. Additional Tips:

  • Safety First: A properly functioning parking brake is crucial for safety, so address any issues promptly.
