Greetings,
My work office has eight EV charger stations to service our fleet of 56 employee owned EVs. A very nice and popular perk! Most of the EVs are Tesla Model 3 vehicles, sadly only one B250e (mine)
One of the Tesla Model 3 owners posted the following to our internal EV forum:
Good morning all,
FYI for EV car owners: I have been experiencing some type of fire-cracking popping sound in the back of my driver seat. It’s happening on the way to work and home yesterday continuously every minute or two, and even I could hear the sound from the outside when all doors closed. Googling people mentioned about the popping sound or banging sound like metal expansion during super-charging, and I experimented it as well but this’s different type.
I am planning to call Tesla support to report the issue today.
Isn't that interesting! It turns out that Tesla issued a Service Bulletin in July 2019 to address this issue. The noise under the driver's seat is caused by blockage of the High Voltage Battery breather, which equalizes the air pressure inside the battery chamber and atmosphere.
Looks like our B250e annual Battery Check avoids this problem by replacing the Desiccant Filter, which can become blocked. The filter's other function is to remove atmospheric moisture from entering the high voltage battery chamber and causing corrosion.
Not sure if Tesla has an annual preventative maintenance program for this issue.
EV tech is fascinating.
