Toyota RAV4 intermittent radio volume control issue with knob, functions normally with steering wheel controls on Toyota RAV4

Some Toyota RAV4 owners report experiencing issues with the radio volume control knob, including the knob stopping entirely, becoming erratic, or the volume unexpectedly dropping to zero. Additionally, some users have noted that there can be no sound from the radio even when stations are displayed, and the volume knob indicator may not reflect any changes. Touch sensitivity problems have also been reported, where slight touches can cause the volume to fluctuate unexpectedly. To address these issues, some owners have found that firmware updates can restore functionality, while others have had success with power cycling the audio system. Troubleshooting steps, such as unmuting the system or using steering wheel controls, may help resolve sound issues. In persistent cases, seeking professional assistance from a dealership is recommended, particularly if software compatibility issues are suspected.
