Ever since getting the car back, the fans haven't been working. I believe these are the fans that cool the batteries. Up until now, whenever I'd plug the car in to charge, the fans would come on and you could even feel the draft if you put your hand under the rear of the car. They would also come on while driving once the batteries got hot enough.
While the car has been driving fine, I've noticed the battery temp has been running about 20+ degrees higher than normal and my range has dropped. Heat is definitely no friend of lithium batteries.
With the fans not working, the car is completely silent. You get a little bit of road noise from the tires but at low speeds it's silent. No complaints about that.
Dropping car off Wednesday morning.
