I received a 2021 Insight Seat Weight Sensor Safety Recall in September 2025 saying that recall replacement parts were now available at Honda Dealers. Ever since I received this notice, none of the Atlanta area Honda dealers are able to remedy the defect in my vehicle due to lack of parts, contrary to the notice saying parts are available.Owner report · Seats · Dec 2025
Under certain circumstances, the portion of the PCU that controls charging of the 12 volt accessory battery malfunctions, sending the PCU into a "fail safe" mode, preventing battery charging and activating warning displays for the driver. This has caused my vehicle to stall while driving, potentially increasing the risk of a crash. Other honda hybrids during this year have been recalled but not by my VIN number, however I am having the exact same issue. Below has me give a specific date but this happens almost every morning.Owner report · Engine · Nov 2025

While my wife was driving my car on a busy road. The servo brake control unit/ pedal simulator broke making it near impossible to stop the car. She had to crash the car into a parking block. And Honda import/export is uncooperative and dismissive of the fact that my wife and daughters lives were jeopardized due to the part malfunctioningOwner report · Electrical System · Sep 2025
On two (2) occasions, the "collision mitigation braking system" braked with no reason. It has happened on a quiet and straight line residential street with no other moving vehicle, pedestrian, animal, or any other obstruction in view. After one second or so of braking, it returned to normal. It is available for inspection. I have not spoken to the local Honda dealer about it, and there were no adverser repercussions. There were no prior warnings of any system malfunction.Owner report · Forward Collision Avoidance · Jul 2025
I am urging your immediate attention to a safety issue affecting the 2021 Honda Insight. The vehicle's infotainment system, which controls key safety features including the Tire Pressure Monitoring System (TPMS), has failed. This malfunction prevents drivers from monitoring tire pressures, applying necessary software updates, and accessing navigation and hands-free features, which significantly increases the risk of accidents. The system's failure distracts drivers and compromises critical vehicle safety functions, warranting an urgent recall investigation. Thank you for your attention to this critical matter.Owner report · Unknown Or Other · Sep 2024
