Symptoms
- Screen displays normally but taps don't register
- Some areas of the screen respond, others don't
- Problem worse with wet or gloved fingers
- Hard buttons around the screen still work
Likely causes
- CommonSoftware freeze affecting touch input onlySometimes the display renders fine but the touch layer stops responding until restarted.
- CommonDirty, wet, or greasy screen surfaceCapacitive touchscreens can struggle to register touches through moisture or residue.
- PossibleAftermarket screen protectorThick or poorly fitted protectors can reduce touch sensitivity.
- Less commonFailing digitizer (touch layer)Physical damage or age can cause the touch-sensing layer to fail while the display still works.
What to do
- Clean the screen gently with a dry microfiber cloth and try again.
- Restart the car to refresh the software, since this often resolves touch freezes.
- Try touching with a bare, dry fingertip rather than a gloved hand or wet finger.
- If you have a screen protector installed, remove it and test the bare screen.
- Note whether certain areas of the screen never respond even after these steps, which suggests a physical fault.
- If certain buttons or a rotary knob duplicate the touchscreen's functions, use those temporarily.
Tools and parts
- Microfiber cloth
When to call a pro
If specific zones never respond even clean and after restarts, the touchscreen's digitizer may need dealer service or replacement.
