NHTSA Complaint #11582551 — 2021 HONDA ODYSSEY

I am writing to urgently bring to your attention a critical issue plaguing the driver assist systems in Honda Odyssey 2018+ vehicles. Despite meticulous maintenance and adherence to manufacturer guidelines, I have encountered a persistent and alarming problem that appears to affect numerous other vehicle owners, as evidenced by online forums and discussions. The issue initially arose during a rainstorm, where I received a warning message stating, "Some Driver Assist Systems Cannot Operate: Radar Obstructed." Despite the weather clearing and thorough cleaning of both the sensors and the windshield camera, the warning persisted. Subsequently, a series of related problems emerged, including: Illumination of the BRAKE SYSTEM LIGHT Malfunctioning adaptive cruise control Faulty collision mitigation system Inoperative road departure mitigation system These errors not only pose a significant safety risk to myself and others on the road but also indicate a systemic issue with the vehicle's safety systems. As my vehicle is just past the three-year mark and out of warranty, I am apprehensive about incurring substantial costs for dealership repairs, especially considering the widespread nature of these complaints among Honda Odyssey owners. Extensive research reveals that I am not alone in experiencing these issues. Multiple reports and discussions online highlight similar complaints from other Honda Odyssey 2018+ owners, particularly following exposure to adverse weather conditions. Therefore, I implore the National Highway Traffic Safety Administration to conduct a thorough investigation into this matter. It is crucial to identify the underlying cause of these recurring issues and hold the manufacturer accountable for any design flaws or defects contributing to the malfunction of critical safety systems. Furthermore, I urge NHTSA to prioritize public safety and take immediate action to ensure affected vehicles are promptly recalled or repaired to prevent further incident
