So I tried searching for this topic, but wasn't able to find much.
The other day when starting the car up after a 4+ hour road trip on an 80 degree day, I heard a loud noise from the engine bay, as though something was being chopped up by the engine fan. Popped the hood and saw that the two battery caps have popped off - one just barely hanging on, one fell and got bounced around by the fan - destroying the fan shroud.
Did a little research and everything is leading to the battery over-charging and creating excess gasses. This potentially being caused by a bad voltage regulator.
Anyone have any experience with this? Any other ideas? Car is less than 4 years old and i'm just surprised to be running into an issue like this already...
any help or advise would be greatly appreciated!
