Lol sorry I'm being a little dramatic with the title of this thread. But seriously, I just started experiencing issues with Sync in my 14 V6 and now a new issue is being thrown into the mix.
Note that the car has ~5,100 miles.
Upon cold start, something squeals loudly. It sounds like it could be a belt, or maybe a tensioner, or something like that. Anyways, the squeal slowly dies down as the engine warms and by the time the engine fully warms, the sound completely stops. It's frustrating as hell to drive such a beautiful car...that squeals.
The sound echoes in my parking garage and a guy getting in his car next to me looked over with a puzzled look when I started it. Embarrassing. Haha
I'd attach a video of it squealing but I'm on my phone. Might be able to get it put up later on.
I'm having the same problem on my truck. Annoying as hell.
Tried new belts, tensioner, tensioner pulley. The squeak always comes back. I'm going to try new pulleys next. I've always been against "belt dressing" because it can collect in the grooves of the pulleys and be a real b!tch to remove.

Yeah I don't have time to fiddle with it by myself with classes and work since I leave my place as the sun comes up and return as it's going down. Lol but my dad offered to come up here tomorrow and swap cars with me and said he'd take her into ford so they can deal with it. Thank god too because I really don't have any time to take it to ford. I figure that if I give it to ford, they'll find and fix the problem because I'm friends with one of the GMs there and he's pretty cool about this kinda stuff. I guess I'll have them take a look at the sync issue while it's there.
My 13 did/does the same thing. I've tried the belt dressing and it worked for a little while but it came back. Mine doesnt do it all the time, in fact its pretty rare and it goes away a minute or two after its running. I took it to the dealer and they put, if I remember correctly, a Teflon on it but it wasn't a long term solution. The sound is between a squeaky belt and/or noisy pulley.
Mine does the same thing and I have 3700 miles and it's been doing it since around 2000 miles. Mine does it after I've driven it and parked it and if I go somewhere 30 mins. Later it squeals. I read on another forum it's due to alternator position. It soaks up the heat and causes it to squeal. Like I said it sounds weird but that's what I've heard from others. Some have tried different alternators and it worked. I'll try to find that thread and post it.

Idk, I let two ford mechanics listen to the video I have of it and neither said that it is a normal sound for the 3.7 to make. If it were the alternator soaking up heat then shouldn't it have done it from 0 miles?
When mine does it, its only on a cold start up. Mine car has 18000 kms on it and has done it since it was new. If that's all I have to worry about with this engine I'll be very happy seeing that its very minor and happens only sometimes, but yeah I would still like to find a more permanent solution!
Yeah the phenomenon which you're experiencing doesn't seem to be the same that I am. If it were only every once in a while, it'd be okay. But it's actually on every cold startup. Pretty lame. Lol
Good, you took it to a dealer for warranty work. Paying what you did for that 2014 Mustang should not have required you to have to squirt belt dressing on it to quiet it down.
Very interesting. There is a video of a guy turning his alternator by hand on page 3 of that thread and it sounds very similar to what I heard. It sounds pretty metallic, like a squeaky bicycle wheel rather than a rubber squeal. BUT, he also claims that the sound is produced after sitting for short periods (so that the engine is still hot and the alternator brushes are a little larger due to thermal expansion). My sound occurs when the car is totally cool (like after it's been sitting all night) only. So thermal expansion of alternator parts doesn't quite add up in my mind. Hmm...
Avoid belt dressing on any belt, anywhere unless its an emergency or very temporary. Belt noise is never acceptable. Ford will take care of you. Good Luck.
Everything under the hood is stock. Completely untampered. Haha I have doubts that it would be the alternator because it does it on cold start when the effects of thermal expansion on the alternator wouldn't be present. And as bucko suggested, if it were a design flaw, this problem would be hugely widespread. It's just that the The sound of the squeaking alternator in the video sounds very similar to mine. Might hear back from them later today, anyway. I swear I will put a fist through a wall if they say that they don't hear anything. Lol
You may be able to but if it's gotten to the point that his did then it probably won't help. I've noticed my doing sometimes when cold too but it's kind of faint

Okay Ford called. They thought it was the idler pulley at first. So they replaced it. They assumed that the ball bearing didn't have enough lubrication so they replaced that. They waited for the car to cool and they test drove it again. Lo and behold, it squealed. So they now are pretty sure that it IS in fact the alternator...which they currently have none of. So I won't get my car back until next week. Blown.
I'm back in possession of the car. I had it sit for 5 hours earlier and then started it up. It didn't squeal. But the real test is when I leave for class tomorrow. It will have sat for about 12 hours and it's going to be below freezing tomorrow. If it squeals don't be surprised if you hear about me on the evening news.

Well I think that I figured out what was causing the squeaky belt on my truck. The air conditioning compressor pulley was out of alignment. It's held onto the mounting bracket with four long bolts. I loosened them all up and moved the compressor exactly opposite of how it was lined up and the squeak almost completely disappeared. It still does it a tiny bit right at start-up, but I can barely hear it when the hood is closed.
I could probably do a better job lining up the pulley, I kind of did this on a whim, I'd tried everything else so I thought what the hell... it seems to have made a BIG difference!
Keep in mind that this is 20+ year old F250 that I'm talking about. I looked on my New Edge and the A/C compressor mounts the same way, with four bolts. Maybe the accessories on the 3.7 are similar?
Anyways, the pulley alignment is something to look at for you guys with a mysterious, persistent belt squeak.
Good to hear your squeak is mostly resolved. The car will be back at the dealership tomorrow morning. Hopefully they actually fix something this time around.
Sucks man, I know the feeling of having a new car then something being wrong with it. My brother has a cts v and his started squealing last week as well, we sprayed some of that belt dressing on it and it got worse. Luckily his car just needed a new belt, as soon as we replaced that it was quiet again. Good luck with yours hope it gets resolved.
Thanks. Also forgot to mention that Ford cracked my radiator cover somehow while it was with them. It's got about a 3 inch crack in it which isn't a huge deal but just to add insult to injury...
