Does your i-Pace sound like a baby goat when you stop?

OK, so I am having a dispute with Jaguar as to where it is normal for the car to emit the sound of a baby goat when the brake pedal is pushed. I get this at least 60% of the time and do not know if it is (1) normal, (2) brakes, (3) suspension or (4) something totally different. It bugs me to death!


It is hard to capture the sound, but it is there and I do not feel that a $90K car should be like this.


Feedback?

Arg. Baby goat, like a bleat? Does it happen during the regen phase of braking or during the friction brake phase?

Could it be that after not using the friction brakes dust/rust builds up and makes the noise on first engage? If you press hard a few times will it do it every time?

I was just informed that mine also has the “baby goat” sound feature apparently!

Wait: how often do you step on baby goats that you know what they sound like?

The noise occurs within about 6 feet of stopping and especially evident when stopping from slower speeds, like getting to a neighborhood stop sign. It is not during the regen phase, as there is no noise if I let the regen stop the car completely with a smooth stop.

Mine was more of a squawking sound that seemed to lessen as time went on. Others have reported similar braking noises and I don’t recall anyone having a definitive diagnosis or fix.

I've got about 1500 miles on the car. Can anyone confirm that they had this when it was new and then eventually went away? Any ideas on the source...brake pads, brake hydraulics, suspension, other? It quietly, but very noticeably goes "bleahhh" for about about 1 to 1 1/2 seconds.

I'll confirm the 'squeak' of brakes applied "in the last few feet" of stopping, particularly when you stop, roll forward, stop again (as at many stop signs with limited view). It is annoying and I was hoping to read about a "fix"... nothing yet. I'm over 5k mi (on this car, I-Pace #3 with identical noise emitted from #1 and #2), so its definitely an issue across all (most?) vehicles, and not just when new.
While we're on the topic of animal noises... does anyone else hear a faint "whoosh" (rarely, but often just after startup) that very much emulates my dog (or a human for that matter), exhaling loudly as if for emphasis? It appears to come from the back seats, which even more simulates the sound I would hear from my dog in the cargo area. Even my kids hear it and chuckle when I ask who brought the dog along...?

I find that the goat squishing noise is related to the car wash. Since I don’t use the friction brakes much (just the last few feet) the brakes seem to make that noise more often when they are wet or not well worn after a car wash. You can ‘burn away’ that sound with a few aggressive stops but you have to make sure you get into the friction brakes hard and I don’t like to do that as it seems hard on the car and unnecessary but it is worth the experiment if you feel that the brakes are not performing correctly. It seems to be the wax or polish from the car wash in my case, so you can avoid this by not washing your car in a car wash and avoid soaping or waxing the wheels if washing by hand. Definitely a moisture related issue for me.

With regards to the flatulence sound from the back seats, it might be your mother-in-law but more likely the air compressor for the air suspension turning off. It sort of sounds like a turbo wastegate whooshing if it was buried under a stack of mattresses.

I’ll confirm this noise as well. I haven’t tracked it as it’s not consistent and I’m still in my honeymoon phase, but I’ve definitely noticed it

I suggest braking hard, just short of ABS, from 60 twice in a row, rapidly. Gets some heat in there. Scrapes off the rust. Then see if the sound is still there or at least softer. If it is softer but not gone, try again from 80 twice in a row. If it's not changed at all, it's possibly some kind of issue.

Photon FE, 2013 FR-S, 2014 Forester, and maybe going to get a Fiat 500e
