Lexus ES300h audio system malfunction with static noise and no sound on Lexus ES300h

Some Lexus ES300h owners report experiencing audio system issues, including static noise and complete lack of sound. These static or distortion noises often occur at higher speeds, such as 65-70 mph, and can persist even when the engine is off, suggesting a deeper problem with the audio system itself. Additionally, some owners find that no sound from the speakers may be due to amplifier malfunctions or the audio system being muted, highlighting the importance of checking mute settings as a troubleshooting step. Problems with the amplifier, including potential water damage from rain entering via the wheel well, can also lead to sound issues. Owners of models equipped with the Mark Levinson audio system may face challenges, as repairs often require specialized services due to the proprietary nature of the system, with technicians typically limited to component replacement. Furthermore, some ES300h vehicles may exhibit front-rear sound imbalance, which has been addressed through updates to the amplifier logic. For those encountering these audio system malfunctions, seeking assistance from a qualified technician familiar with Lexus audio systems is advisable for proper diagnosis and resolution.
