2024 Polestar 3 Pilot Assist & ADAS Sensor Errors - Intermittent Warnings

Vehicle: 2024 Polestar 3 Long Range

Hi everyone,

I just got my 2024 Polestar 3 Long Range a few weeks ago, and I'm already experiencing some frustrating issues with the advanced driver-assistance systems (ADAS). I keep getting intermittent warnings like 'Pilot Assist Unavailable,' 'Front Radar Blocked,' or 'Camera System Error' popping up on the screen.

It's not constant, but it happens frequently enough to be annoying and sometimes startling, especially when Pilot Assist suddenly disengages. I've checked the sensors for dirt or obstructions, and everything looks clean. There are no specific OBD-II codes I can pull with my basic scanner related to these warnings.

Is this a known bug or a more serious diagnostic issue? What should I do? It's a brand new car!

ClearTheCode admin answer:

Intermittent ADAS (Advanced Driver-Assistance Systems) sensor errors on a new vehicle like your 2024 Polestar 3 can be concerning. These systems rely on a complex array of cameras, radar, lidar, and ultrasonic sensors to function correctly. While a 'Front Radar Blocked' message often points to a physical obstruction, intermittent issues after cleaning suggest a deeper diagnostic problem.

Here are potential causes and recommended actions:

  1. Software Glitches: As a new model, software bugs or calibration issues are possible. Updates are frequently released to address such problems. Ensure your vehicle's software is up to date.
  2. Sensor Malfunction: One or more of the ADAS sensors (radar unit, camera module, ultrasonic sensors) could be faulty or experiencing an internal error. Even if clean, an internal component could be failing.
  3. Wiring or Connector Issues: Loose, corroded, or damaged wiring to the sensors or their control modules can cause intermittent communication errors, leading to the warnings you're seeing.
  4. Sensor Calibration: If a sensor has been slightly knocked out of alignment (even without visible damage), it may require recalibration. This is a precise process that needs specialized equipment.
  5. Control Module Fault: The central control unit that processes data from all the ADAS sensors could be malfunctioning.

When to see a shop:

  • Schedule Service Immediately: Since this is a brand-new vehicle and the issues are persistent, you should schedule an appointment with a Polestar service center. These systems are critical for safety and driving convenience.
  • Detailed Diagnostics: A Polestar technician will have access to advanced diagnostic tools that can read specific fault codes from the ADAS control modules, which generic OBD-II scanners cannot access. They can also perform sensor calibrations and test individual components.
  • Warranty Coverage: As your vehicle is new, these issues will almost certainly be covered under warranty. Document all occurrences, dates, and specific warning messages to provide to the service center.
