All 1 Known Issues
On the 2018-2025 Lexus LS, the LS500 infotainment system suffers from significant input lag and an unintuitive touchpad controller that makes basic navigation tasks difficult while driving. The Remote Touch Interface trackpad requires excessive concentration to use accurately, and the system frequently freezes or responds slowly to inputs. This has been a consistent complaint since launch.
Common Symptoms
- Multi-second delay between input and screen response
- Touchpad overshoots or misselects menu items
- System freezes requiring vehicle restart
- Navigation destination entry takes excessive time
- Bluetooth audio connection drops intermittently
How to Fix
Update to the latest infotainment software at the dealer, which improves responsiveness somewhat. Lexus has released multiple software updates since 2018. The 2022+ models received a touchscreen that partially addresses the issue. For older models, using voice commands or Apple CarPlay/Android Auto bypasses the native interface.
