The National Highway Traffic Safety Administration (NHTSA) recently announced a comprehensive investigation into approximately 28,000 Polestar 2 electric vehicles, spanning model years 2021 to 2025. This action stems from a recurring and unresolved problem with the vehicles' rear-view cameras. Despite Polestar's previous efforts to address the issue through two separate software-based recalls, the NHTSA's Office of Defects Investigation (ODI) has continued to receive numerous complaints from owners reporting delayed, distorted, or completely non-functional camera displays when reversing. These persistent failures are critical because they directly violate Federal Motor Vehicle Safety Standard 111 (FMVSS 111), which mandates clear and reliable rear visibility, thereby potentially increasing the risk of accidents, even though no crashes or injuries have been directly attributed to this defect so far.

Polestar's initial recall, identified as 24V-477, was issued in June 2024 and aimed to mitigate graphical rendering limitations within the Infotainment Head Unit (IHU) by optimizing camera stream retry times and reducing memory usage during reverse maneuvers. However, this software update proved insufficient, as user complaints continued to mount, indicating the problem had not been fully resolved. This led to a second recall, 25V-280, in April 2025, which introduced a more aggressive software solution designed to maintain a consistent high-speed signal connection between the parking assist camera and the IHU, alongside a hardware reset mechanism for synchronization errors. Yet, even after this more comprehensive update, the ODI confirmed that new reports of camera malfunctions began surfacing by June 2025, compelling the agency to initiate a formal inquiry to assess the adequacy of Polestar's fixes and determine if further regulatory measures are necessary to ensure vehicle safety.

This ongoing situation with the Polestar 2 highlights a broader challenge emerging in the automotive industry: the intricate interplay between hardware and software in modern, technologically advanced vehicles. While over-the-air (OTA) updates offer a convenient and rapid method for deploying fixes, this case demonstrates that some issues, particularly those involving complex system interactions, may not be easily resolved through software adjustments alone. It underscores the critical need for manufacturers to thoroughly diagnose and rectify underlying hardware-software integration problems, ensuring that safety-related recalls are genuinely effective. This pursuit of robust and reliable automotive technology is essential for enhancing consumer trust and driving forward innovation in vehicle design and safety standards.
