On the 2018-2023 Lexus LC, the LC flagship coupe shares the same frustrating Remote Touch Interface touchpad and laggy infotainment as other Lexus models. On a $100,000+ vehicle, the slow response times and imprecise touchpad control are a particularly sharp contrast to the otherwise exceptional driving experience. The system is widely criticized in professional reviews.
Update to the latest infotainment software version. The 2022+ LC received a touchscreen update that significantly improves usability. For pre-2022 models, use Apple CarPlay (added 2020) or voice commands to minimize touchpad interaction.
Parts and tips from 1,200+ owners who fixed this issue
On the 2018-2025 Lexus LC, the LC500 V8 produces a prominent exhaust drone in the 1,800-2,200 RPM range, which corresponds to 65-80 MPH highway cruising in the 10-speed automatic. The drone is a resonance issue where exhaust frequency coincides with cabin structural resonance, creating a low-frequency hum that becomes fatiguing on long highway drives.
Install aftermarket exhaust resonators or a Helmholtz resonator to cancel the drone frequency. Some owners have had success with Dynamat sound deadening material applied to the trunk floor and rear firewall. Switching to Sport mode forces lower gears and higher RPM that avoids the drone window.
