Recently I starting noticing a terrible noise coming from underneath the front passenger side bumper. Often happens when I go to plug the car in at night. Here's a video grab I got of it last night. You'll hear it right off the bat: Tesla Model S Pump Noise? - YouTube The humming noise heard in the background is normal - I believe it's related to the coolant pumps. However, the fact that it coincides with the coolant pumps has me wondering whether one of them is on the fritz. Car is going in for service tomorrow, but I'm not quite sure how to explain the noise to them. Anyone else heard this before and know the source?
