Hi everyone. I am a lucky owner of a fantastic Lightening Lariat. The truck intermittently makes a whining noise (sounds like a distant leaf-blower) when in use. This noise does not seem to have any predictability to it. It has happened in 75F and in 25F weather. Sometimes you can turn the car off and restart it and it disappears. Other times starting and stopping does not remove the noise. It is quite apparent when the truck is not moving. It can happen after driving the truck for a while or rarely on starting for the first time. I took it to the dealer and the mechanics felt it was due to a cooling pump for the battery and they heard it in another Lightening that the dealer had. Anyone else have this noise. The dealer said this seemed to be a lightening issue, but curious if others have this. I feel petty making this post, but in an 80k truck this noise drives me a little bonkers.

What you describe (leaf blower) sounds like.............. a fan? Maybe an HVAC pump?

Both are normal sounds....

Thanks for the reply. The noise is more easily heard when the heating/cooling fans for the inside of the truck are all turned off. I was told by the mechanics that this might be the cooling pump for the battery.

I experienced the same thing when test driving various mannequins. Sales dudes were clueless, even after giving them a few weeks to research (they didn't). It comes from behind the soft back wall of the frunk. You don't hear it inside the cab, but sounds like an airplane taxiing on the outside.

This video may help at least narrow down location of components that could be making the noise if it's not coming from the cab. Inside the cab all the only noisemakers I can think of is the blower motor or the ventilated seats.

Is it when you are driving or does it happen when you are also stationary? We had a fusion plug in that when we were driving, it put off a high pitch whining sound. after several months of constantly taking it back for service, we discovered it was the electric motor noise feedback canceling system that had failed and needed to be replaced.

Sounds like an HVAC pump. Very normal sound in a vehicle, but the engine noise masks it in an ICE. They will come on randomly in an EV, vehicle moving or not, "on" or not, to keep your high-voltage battery happy.

Sounds like it is coming from the area of the Max Tow compressor that Munro guys commented about the extreme NVH isolation mounts Ford used. It seems more pronounced than mine. Maybe that black outer sound deadening jacket is loose or missing.

I hope @jbhiggs has Max Tow or that theory is shot.

Hi there, I'd be happy to look into your Lightning concerns on my end. Will you send us a message with your VIN and dealership info? I can look into things on my end.
