Vehicle: 2018 Acura RLX P-AWS Tech

Hello fellow RLX owners,

I've been having persistent issues with the infotainment system in my 2018 Acura RLX P-AWS Tech. The screen frequently freezes, becomes unresponsive to touch, and there's a noticeable lag when switching between functions like navigation, radio, or Apple CarPlay.

Sometimes, it'll just completely black out for a few seconds before restarting, which is incredibly frustrating, especially when I'm using navigation. I've tried holding down the power button to reset it, which works temporarily, but the problems always return within a day or two.

Is this a known bug with the 2018 models? Has anyone found a permanent fix or a reliable workaround? It's really detracting from the otherwise premium experience of the car.

ClearTheCode admin answer:

Infotainment system glitches, freezing, and lag are unfortunately common complaints across many modern vehicles, including some Acura RLX models. Your 2018 Acura RLX P-AWS Tech's symptoms align with typical software or hardware issues within the head unit.

Common Causes:

  1. Software Bugs: Outdated or buggy software is a primary culprit. Manufacturers often release updates to address these issues.
  2. Hardware Malfunction: Less common, but internal components of the head unit can fail, leading to instability.
  3. Overheating: Prolonged use or high ambient temperatures can sometimes cause the system to slow down or freeze.
  4. Corrupted Data: Issues with connected devices (e.g., faulty USB cables, corrupted media files) can sometimes interfere with system performance.

What to Do:

  1. Perform a Hard Reset: While you've tried the power button, sometimes a more thorough reset is needed. Consult your owner's manual for instructions on how to perform a factory reset of the infotainment system. Be aware this will erase personal settings.
  2. Check for Software Updates: Visit your Acura dealer or check the Acura owner's website for any available software updates for your specific model year's infotainment system. A dealer can perform this update for you.
  3. Isolate the Issue:
    • Disconnect all external devices (USB drives, phones via Apple CarPlay/Android Auto) and see if the problem persists. If it resolves, the issue might be with a connected device or cable.
    • Try a different USB cable if using CarPlay/Android Auto.
  4. Professional Diagnosis: If the problem continues after software updates and resets, it's advisable to have an Acura dealership diagnose the issue. They can check for internal hardware faults or more complex software corruptions that require specialized tools. They can also check for any technical service bulletins (TSBs) related to your specific symptoms. There are typically no OBD codes for infotainment issues unless they affect critical vehicle functions.
