Just so you guys know, this is also a problem on my 2014 KL trailhawk. No thread about it over in the KL section and I was starting to think I was alone with this problem. I was thinking it was an exhaust issue.

Re: Cold weather starting noise

I just got this on my 2014 GC Limited 3.6L this am... Remote start wouldnt work (because of some other problem.. the MIL light is on) and I walked out and started it to hear this high pitched wooooooo .. loud. Never heard it before and its been cold here for months.

Great.... another "item" to add to the list of this POS. cant WAIT for 3 years to be up.

Re: Cold weather starting noise

Good day gentlemen

I have a 2012 3.6 with 21000 miles - I have this problem currently

Located in Chicago - currently 0 degrees F

If I had to guess its just a belt/tensioner problem that will not affect longterm

But I could be wrong

Re: Cold weather starting noise

My 2012 overland 5.7 make a squealing sound on cold mornings here in VT. I'm not worried about it. Poop happens when its cold. Only makes noise for 3 to 5 seconds and its gone. I'm not going to let it bother me.... I squeal a little when its cold outside too...

Re: Cold weather starting noise

LOL... you'd squeal too if someone started you up on a sub-zero morning.

Strange sounds are pretty normal under those circumstances.

Yup. Sometimes it is the belt, but another culprit is the bearings in the tensioners squealing because the lubricant at those temperatures is more of a glue than a lube.

If the sound has gotten worse at similar temperatures, it is worth checking the bearings and either replacing or giving a careful shot of a silicone based lube.

Unfortunately no... I haven't encountered the banshee yet.... and it was a tad chilly for a few days here.
