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. :surprise::surprise: 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.

Do all the rotors look as though they are wearing correctly and no unusual grooves in them? A defective rotor will have a high spot (warp) and at slow speeds will emit a squeal. Also a loose caliper could make a noise at slow braking speeds and not be heard on hard braking. Most likely you have all checked these components. Is it possible to determine which corner of the car the sound is emanating from?

My first impression after hearing the Jag's brake squeak was that I was driving an old farm truck. I had almost the same thing on my Ford Focus Electric after washing the car and not driving it until the next day, although it was more of a grinding sound than a squeak. It would go away after some decent braking occurred. The Jag has more regen and less braking than the Ford had. The cast iron disk brakes are rusting is part of the problem. Next option should be carbon brake disks! I think some of the noise may also be coming from the pad backing plates and/or the caliper pins needing some grease. Most motorcycles recommend a special grease on these parts to prevent the squeal. The grease came with new pads.

Almost $14K miles and have always had a groaning noise when using friction brakes to come to a complete stop or when releasing the brakes after applying the manual parking brake and the car inches forward a fraction of an inch before stopping. Sometimes it's less, sometimes more, but always there. Two dealers did not find anything wrong, according to both it was normal behavior (which still bugs me).

In my case the noise is caused by corrosion on the discs. I live on Lake Huron and it's always humid. Add to that, I tend not to use brakes very often so if the car sits for a few days unused, there's a mild brownish tinge to the discs - rust.

Jsimons advice is good - the brakes need to be hammered occasionally. 160 kms/hr followed by emergency braking does it for me. And then the discs shine!

Normal? I've owned a dozen cars ranging from a used Toyota Camry to 2 corvettes to several Mercedes and BMWs. NONE of them had break 'squeals' unless there was a brake PROBLEM. Clearly based on the number of people experiencing this I-Pace Break Squeal is a DESIGN flaw that the dealers can't fix! They can't get paid for attempting so they just tell you that as an excuse. If it is 'normal' why don't other Jaguar and Land Rover vehicles 'squeal' like that??

Dtgsrq, I think what many people agree on is that the friction brakes do not get used much since the majority of the braking is done regeneratively. Combine that with excessive washing (I have the Petro-Canada Season’s pass that allows a wash once per day for 90 days) and your brakes get a little contaminated with soap and wax or polish and squeal (or bleat depending if you brakes sound like a piggy or a goat) and it takes longer to dry them out. Some observations from some of the other members indicate that clean dry brakes don’t make noise and that there isn’t really a defect as such. A test would be a few agressive stops to see if your brakes clean up. Obviously I can’t base this comment on proof, but just my observations. The biggest difference between the iPace and all the other cars you listed is the regenerative braking.

I had "grabby" brakes with 'creep' on and also the goat noise. The 'gabby' brakes were improved a lot after Jaguar did a short brake software update. The goat "almost" went away completely when I switched to high re-gen and turned off 'creep'.

I believe part of the squeak, is like ryzvy said above , it is the parking brake engaging at full stop. My wife's old Outback had an electric parking brake and it made a similar sound if you were moving (neutral) when you applied it. The Outback had a motor screw mechanism that put the parking brake on. You can just barely hear the electric parking brake motor on our I-Pace's as the squeak comes in. If you allow our cruise control/follow mode to stop the car, on a slight incline backward, the electric parking brake is definitely the culprit. I still say the fix is grease in the right spot.

I would say it's the electromechanical brake actuator. All ICE cars use an actuator that is driven by manifold vacuum. As the brakes hardly get used I welcome the sound as a reassurance that the actuator is working. I would suggest get used to it and enjoy the car.

I'm surprised there are no complaints about the whining commutation noise that comes from the motors.

I've been getting the "bleat" just as I stop at times too. I'm thinking it is likely that both jsimon7777 and Timbo are on to the right idea.

It is a widely known issue in the Porsche 911 world that the brakes will start making similar noises as you stop IF you don't at least occasionally drive/brake aggressively enough to get some good hardy brake wear. This is most often seen with people that drive their 911's for the luxury/show factor. It seldom happens for the harder core driving enthusiasts that are harder on their brakes. The noise comes from the pads building up a bit of a glaze that doesn't get rubbed off frequently enough with aggressive use of the brakes. The common fix is what jsimmon7777 says, several very aggressive stops in a row (with no traffic around of course!), followed by a short drive to allow the rotors to cool down before parking after the last heavy stop.

Given that many of us I-Pace drivers are using one-pedal driving and have little actual brake pad use due to blended regeneration even when we do brake, our brakes may be experiencing the same problem and the pads just need a little aggressive cleaning. It hasn't bothered me enough to try this, but the next time I'm in a good place to do this I'll give it a shot and report back.
