2020 RX 350 Infotainment Freezing and Apple CarPlay Disconnecting

Hey everyone,

I've been having some frustrating issues with the infotainment system in my 2020 Lexus RX 350 F Sport. Lately, the screen has been freezing completely, sometimes for several minutes, and then it might reset itself or I have to manually turn the car off and on.

The biggest problem is with Apple CarPlay. It constantly disconnects, especially when I'm using navigation or streaming music. It's really disruptive and makes using the system almost impossible.

Has anyone else experienced this with their RX or other Lexus models from around the same year? I've tried restarting my phone and even doing a soft reset on the infotainment system (holding down the power button), but the problem keeps coming back. Wondering if it's a known software bug or something more serious.

Summary: For 2020 RX 350 Infotainment Freezing and Apple CarPlay Disconnecting, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
