Hi all. Started getting this weird noise recently and thought I would toss it up here and see if anyone recognizes it. My first thought goes to brakes, but I can't identify where the noise is actually coming from. Seems like from the rear.
The deets: 2017 Automatic Lusso, 42k miles, has MGP caliper covers.
I am not sure whether pads or rotors have been replaced. When I bought the car it had 38k miles and the caliper covers already installed. Brakes were fine and passed prepurchase inspection. Without removing the wheel it appears that rotors are not heavily worn or grooved or anything.
It whines like this intermittently, but most noticeable and most often in the first 5-10 minutes of driving. Sometimes it will stop when I come to a complete stop at a light or stop sign. Then it will go away for a bit. Did not hear it driving to work this morning (about a 15 minute drive), but heard it in the first minute or so when leaving work this afternoon. I heard the whine, came to a stop and it went away. Heard it again when the light turned green and I hit about 25mph. In the video I am driving around 45mph range and as you can hear it kind of starts and stops without regard to speed or throttle. Any ideas?

Auto box whines for first 5 or 10 minutes while transmission warms up so could be this and you are not used to the sound. It's normal for this transmission. I actually thought there was something wrong with my car until I looked into this. Not to be confused with the whine form the turbo. I can still barely hear the trans whine when it is warmed up also.

I definitely get the auto trans whine and I’ve gotten used to it. For me, it goes away or at least becomes somewhat unnoticeable after warm up. This is something else. Today, it happened again on my way to work. It seems to be affected by braking/stopping but if it was a brake issue wouldn’t it happen all the time and not intermittently? Curious. I’m close to pulling the trigger on replacing all the pads and rotors and see if that does it. It pains me to spend money and replace something that doesn’t need replacing but if it doesn’t solve the problem at least I’ll have a new set of brakes to show for it.

If you do replace the brakes, I'd upgrade to EBC yellow stuff pads and maybe cross0drilled discs as the Brembo setup is not adequate imo.

Not sure i would jump to replacing the rotors. If you suspect an issue with the brakes it is easy to remove the tire and give it a good look to make sure there is not something out of whack. pads is a simple replacement and i would do that before doing the rotors.
Agreed. I haven’t even bought a jack and jack stands yet! Who knows what I will find when I take the wheels off…
Obviously though, with the caliper covers being there someone has had their hands on the brakes.

Rotor covers? I'd yank those.
They are red and give a little pop of red color to my otherwise tame white Lusso. Plus, they do seem to cut down on brake dust. Unless there's some safety or wear issue I'll consider leaving them but I'm not married to having them. I could take them or leave them quite frankly. I just think they look nice. Why do you suggest taking them off? Do you think they could be the noise culprit?

Not sure. Just an assumption based on past experiences of owner installed mods causing problems. My thoughts were that the covers might be touching the rotors.

I own 2017 Classic. At around 2,000 miles I was hearing a medium pitch whine which sounded like it was just below my seat. Took it to dealership and FIAT mechanic said the differential was SHOT. They replaced it under warranty. $2,300 was the price.

That was my worst nightmare scenario. Thank god it was just the brake pads.

Bought my Abarth with AT about a year ago with 17k miles. Have always had the “whine”. I too have gotten used to it. I’ve read about everything I could find including all the threads posted on this site. There are a number of folks who I’m sure are much more educated on this than me. It happens most for me when it’s cold (like everyone else), but particularly when decelerating and down-shifting. Seems it is transmission or what I think, possibly the differential gears. It seems like until the differential oil is warm, it happens.
I actually took it to the dealership and asked them to check it out… and they came back and said, “Nope, don’t hear a thing”. I tried to insist on taking the Tech for a drive but the dealership shut that down completely.Having done that, if “it” ever goes bad, I’ll be back to the dealership pronto. 🤷🏻

I sincerely doubt it has anything at all to do with the pads, rotors, calipers… that would be an expensive waste of time!

I have the exact same rotor covers and they also have nothing to do with the whine.
