The 2023 Genesis G80's available Lexicon premium audio system promises concert-hall sound quality. When this sophisticated system starts cutting out, producing silence or intermittent audio, the luxury listening experience is compromised. Understanding this multi-component system helps identify where problems may lie.
The Lexicon System Architecture
The Lexicon system includes multiple amplifiers, 21 speakers (in some configurations), complex processing, and integration with the infotainment system. Audio passes through numerous stages from source to speakers, and problems can occur anywhere in this chain.
Common Cutout Symptoms
- Audio drops to silence momentarily
- Specific speakers stop working
- All audio cuts out simultaneously
- Static or distortion precedes cutouts
- System works normally, then fails
- Audio returns after system restart
Primary Causes
Amplifier Issues
The external amplifier powering the speakers can overheat, develop electrical faults, or experience internal failures.
Wiring Problems
Speaker wires or power connections can develop issues from vibration, corrosion, or loose connections.
Software Glitches
The audio processing software can have bugs causing temporary failures that restart resolves.
Head Unit Problems
The infotainment system controlling audio can experience issues affecting output.
Speaker Failures
Individual speakers can fail from coil damage, cone deterioration, or connection issues.
