Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
