Subaru Legacy radio malfunction with intermittent audio issues and feedback noise on Subaru Legacy

Some Subaru Legacy owners report experiencing radio malfunctions, including intermittent audio issues and feedback noise. These problems may stem from faulty wiring or short circuits in the electrical system, which can disrupt radio functionality. Additionally, issues with the amplifier or radio components, such as corrosion or damage, could contribute to these audio disturbances. Some owners also encounter glitching infotainment systems that result in working displays but missing sound. To address these concerns, it is recommended that owners inspect the car's wiring for wear or damage, clean or replace the amplifier if corrosion is found, and perform a radio reset or firmware update to resolve any infotainment system glitches.
