This is the SECOND TIME I am reporting this same issue with my accord. I see there is now a recall but I need this to be on file as I can't continue owning this vehicle if this continues. This is a SCARY situation when you are behind the whell. On 10/30/25, I was 60 miles into a trip and the car lost all power on a major highway.
