Common symptoms of a faulty Lexus IS radio (86140-53161)
We regularly receive units with identical symptoms. Most commonly reported issues include:
• The radio does not respond to buttons or knobs
• Continuous system rebooting
• Lexus logo appears and the system restarts (so-called logo reset)
• Device resets when Bluetooth is activated
• No access to multimedia or navigation functions
The issue usually worsens gradually until the radio becomes completely unusable.

What causes this failure?
In Lexus IS models from these years, the problem is not software-related but caused by internal electronic failures within the head unit. The most common faults affect:
• power supply stabilization components,
• CAN communication control circuits,
• system boot initialization components.
As a result:
• software updates do not solve the problem,
• battery reset does not fix the issue,
• replacing the entire unit is very expensive and the units are often hard to find.
