Having issues with 2009 Honda Odyssey. I’ll describe, but I can’t be certain these things are related.
This morning, battery was dead for no apparent reason. No lights were left on, etc. Battery is brand new.
After jump-starting, car ran fine for a few moments, then starting making loud intermittent “buzz” sound from engine/radiator area, down inside maybe on the left side of the radiator. There was also smoke rising from the engine.
I don’t know much about cars, unfortunately, but cursory research suggests it might have something to do with the AC system.
I have attached a MOV which captures the sound it was making.
Any thoughts or advice appreciated.
