Question Steal on Start Up 2014 Grand Cherokee Limited

Just spent 4 hours at the dealership and they could not recreate this issue.

The temps here in VA, USA finally fell below freezing for the first time this winter. For the last 3 days when I start the Jeep there is an ungodly loud squealing whine under the hood.

The sounds gradually lowers, then disappears after the engine has warmed for about a minute or two.

The dealer says the belt is fine, the pulleys are fine--and of course they couldn't reproduce the noise even after the vehicle sat in the cold 3 hours.They suggested it could be the alternator charging, but I have never heard a sound like this that was normal in any vehicle. I've attached a video of what it did this AM before I drove off to the dealer.

It does not happen after the car sits in a garage at work for 9-10 hours; only in the AM.

Anybody have a similar issue or a suggestion?

Re: Squeal on Start Up 2014 Grand Cherokee Limited

Well, now that I fixed the typo in my original post it might make more darn sense.

A gear head at work suggested that the vehicle is not getting enough air on start up due to an intake flap sticking on freezing morning. Back to the dealer on Monday so they can keep it overnight and start it cold to try to diagnose the problem.

That is almost certainly not the problem

Post the audio/video somewhere (I didn't see an attachment?) ... let's hear what it sounds like..
