Lexus LS460 Mark Levinson audio system failure with chirping noise and intermittent operation issues on Lexus LS460

Some Lexus LS460 owners report experiencing audio issues with the Mark Levinson system, including chirping noises and intermittent operation problems. These issues are often attributed to the amplifier, which can cause popping noises, no audio output, and even blown fuses due to water damage. Some users have noted that the amplifier may need to be repaired at an aftermarket cost of around $700, or replaced by Lexus for approximately $2600. Additionally, there are reports of sound quality distortions persisting even after the amplifier has been replaced. The proprietary nature of Levinson products means that repair manuals are not easily accessible, making replacement the primary solution for addressing these amplifier-related problems in the audio system.
