Malena, my 2012 FIAT 500 Sport, reached 165,000 miles a few days ago. As I approached my driveway, I heard what sounded like an electric motor following the revs. Neutral, clutch in, minimal noise. Engage 1st, then 2nd and the noise is still following.
What I wonder is since the sound disappears when not in gear, it's not the throw-out bearing or clutch/pressure plate.
Since it seems to be from the driver's side, the half-shaft seems to be fine, so I can only presume the transmission has a bearing failure.
I commute 100 miles a day to work and home and this is the first major issue I have faced in almost 3 years of ownership,
What does this group think? Am I missing something in my analysis?
I have not changed the transmission fluid since I purchased it in 2016. Neither has the dealer. I do my own oil changes, filter changes and spark plugs.

Hey, you are just down the road. Congrats to Malena... the first 500 that has some mileage. I don't know enough about these cars, but this is what I'd check. If you could post a recording, it might help.

To clarify what I'm hearing: Car running, the car is standing still in neutral and there is no noise (even when listening under the hood). You push in the clutch, no noise, but put it in gear and the noise starts softly. Then the noise starts getting louder as you drive away and pitch changes with RPMs, not with with car speed.

Do you hear it in reverse? Perhaps have someone help, so you can lift the hood and listen. Try in neutral, foot off the clutch, then have them raise the RPMs slowly as you listen. Repeat with the clutch in. Sometimes faint sounds can't be heard inside and/or seem to come from a different location on the car. Oh, and have the radio powered off. I got fooled once by static coming thru a stereo.

Fiat says the tranny oil is lifetime, so not changing is on them. It would be smart to change it; maybe the noise will lessen. Can you see any signs of oil leaks? I doubt this is relevant, but any work done on her in the last couple months other than oil changes?

Just an O2 change (downstream) and the 152k major service. That is the big $ job: water pump, timing belt and the associated tensioners. That was done by the dealer and I have put 5,500 miles on since it was done.
My son is assisting me today and we will report on this later.

Alright, it is not the transmission. With his better hearing, my son said the noise is from the driver side. And it does increase with rpms, but only when the clutch pedal has some pressure applied. Resting my foot on the pedal started the noise and fully engaging the clutch made the noise louder.
I drove it in front of my house a few time and I could hear the noise going forward, but not when backing up.
As we talked more, we both think the release bearing is the culprit. I will contact my dealer Monday to learn more.

With the assistance of my son, this forum, my mechanic and dealer's service advisor, the throw-out bearing is the noisy bugger that will be replaced next week.
At the same value of my mortgage payment! Yikes! 6.8 hours is what was quoted. I joked with my co-workers, who tried to convince me to do the job myself, that the engine probably needed to be pulled to do the job.
I can replace the clutch on my 1966 Chevrolet C-10 with minimal effort. I have replaced the clutch on a 1972 FIAT 128 sedan many moons ago. Winter, wet, cold, outside and a girlfriend who sat on a 2x6 to support the tranny during installation.
I honestly cannot fathom the time to do this job, but I am willing to pay the dealer for their experience.

Brilliant decision. It is a lot of work for the average home mechanic and is an excellent time to have them check on other items... like timing belt, CV joints and a tranny oil change. I look forward to hearing all is well.

Just for my peace of mind, I am changing the transmission oil Friday, taking a sample while it drains and will send it off to be tested.
I have been using Blackstone Labs for 10+ years now and at their suggestions, I have extended my oil changes to 10k to an accidental 15k. The last report on the engine was similar to the previous ones: Malena has a heart(engine) that loves to run hard to maximum rpms and putter around 2000 rpms when I'm in the mood.

Thank you for the tip on the lab you use. I look forward to hearing Malena is back on the road again.

After consulting with my local garage (whom I trust) they referred me to an Italian car specialist who recently did my timing belt and water pump service. Saved a few bucks over the dealer and they were actually even closer to my house. Finding a good indy mechanic is worth it.

What happened yesterday? I drove through an old neighborhood and stopped to talk to my old landlord. After saying our good-byes, I drove off to work. Huh? No noise at start up, No squealing, no noise rising with the rpms, nothing.
I did smell a hot clutch smell when I pulled into work. The drive home did have some instances of being noisy, but not the constant whirring, squealing noise of the past 4 days.

I need to approach this thread again with a correction: too many miles listed in the first sentence.
My mileage reading was 162,440 at the first noisy encounter. I re-read the thread and realized my mistake.

If it is the throw out bearing, no noise and a burning smell could mean it is seizing up. When it goes, it will wear the fingers off the pressure plate.

Well, I forgot about the release fork being in cahoots with the throw out bearing.
I received a call from the dealer that was less than cheerful, but taken with the biggest grain of salt I could find.
The flywheel showed hot spots(I smelled burning clutch), so it will be replaced. $350.00=ouch!
The release fork is toast and 3 days away(the 2 days of the weekend are included).
So, the estimate they gave me was under $1400.00. It now is approaching $1900-2100.00. Plus the car rental.
Ah, I needed this day off.

WOW how often do you look up a problem and find a current thread on it. Instead of a 4 year old dead thread that you can't revive lol

Anyway, I want to say I'm having a very similar issue, maybe you can confirm :)

I recently replaced my ( completely toasted) clutch with OEM replacement and decided to go with a lightened flywheel.
I've had a lightened flywheel in the past so I expected the chatter
What I didn't expect was the whining noise when entering 1st from a stop or even when shifting into second sometimes.

Heres what I know:
  • I can disengage the clutch completely and run through all the gears without hearing the whining.
  • the second I come off the clutch it starts to whine, almost as if it were slipping across the brand new clutch/flywheel.
  • It makes no noise when in neutral or in any gear when the clutch is engaged.
  • Once fully in gear the whinning goes away.

Does that sound similar to yours?
(I don't mean to thread jack and will gladly make a new post if this is not similar to yours :) )

Let us know how it turned out when you get it back!
