I am a new member. My name is Dave. I joined so that I might get some guidance on an issue. I have with a brand new 2017 XJR Sport. I bought it a few months ago with 15 miles on the clock. After a day of driving I noticed a subtle but annoying humming sound. It starts at very low speeds around 12 MPH and comes and goes depending on the road surface and at all speeds. It is there at all speeds although it can be quieter or louder at times. It fills the whole passenger area and there is no distinct location of its source. It sounds the same from the drivers seat or the passenger seat or the back seat....same sound same loudness. The dealer has had the car for 20 days trying to locate it. They have changed the wheels and tires. That made no difference. Used chassis ears all with no luck. If I drive over a expansion joints on a bridge, the humming changes pitch as the front and rear wheels pass over the bump. The pitch of the sound changes with both the front and rear wheels going over the bump.The humming is there even if I put the vehicle into neutral and coast. Braking makes no difference either. The dealer has checked the prop shaft bushing, brake pads cooling fans and anything that may be loose on the car.

I do have a video with the sound on Youtube but did not know it it was ok to post here.

I have owned several Jaguars and have never heard a sound like this. It is NOT a mechanical sound. it is more like a harmonic sound. Sorta like the sounds from a freezer fan motor electrical hum.

Any ideas would be greatly appreciated.

What a great welcome. I thank you all. I feel a bit lowly as a newbie and only having had 2 X300 and now my new X351.
I get the distinct feeling this sight is more technical and engaging than some of the others. As an ex ( retired) mechanic I appreciate well informed blokes as yourself.
I will need to use the link Norri provided as I am not certain how to get around the forum as of yet.

Thank you Grant Norri and sklimii for the welcome.
