I was driving 70mph on an interstate. The battery light came on. There was no immediate change in vehicle performance and there were no odors present so I continued driving for several minutes towards the next exit. About . 5mi away from the exit, the abs, fcw, ldw, and brake lights came on, the air conditioner and console turned off, and the automatic transmission disengaged. This prevented the vehicle from being able to accelerate. The entire vehicle essentially lost power. The local dealer diagnosed the issue as an oil leak in the spool valve that then destroyed the alternator and fried the battery. The manufacturer (Honda) recenty issued TSB 20-023 detailing the problem and repair procedure, but it was limited to the source of the leak, not any of the other components that were damaged. My understanding of the incident leads me to believe a fire could have broken out due to the location of the leak onto the other engine components.
