My 2017 GT has a whine sometimes on cold start up. It sounds like an old power steering pump. I have checked several other V6 Challengers at the dealer all of them had it so it seems to be a common noise I figured it was coming from the transmission since I have heard automatic transmissions whine sometimes when cold. I am not worried about it as it goes away when I put it in gear no noise and it shifts fine. I never thought of it being a harmonic noise until now but it seems very likely now that I have read about it here.

Could very well be the alternator as mentioned...at temps the PCM requests more voltage although I never thought of the brake booster. On my liberty the power steering pump whines when temps are below freezing. I have a manual challenger and hear no whine but on my JGC 5.7 I do get a faint whine. This has me thinking could it be the trans pump could be another source (although the JGC also has a PS pump). :dunno:
So it was -8F this morning and all my vehicles with automatic trans & power steering pumps made a noticeable whine (more like a groan) at start-up, but my manual trans challenger did not. This means either the power steering or trans is making the noise. Now if the noise is the same as the OP (has an SXT which is an auto with electronic steering...no pump), it leads me to believe the trans is making the noise at start-up.

If that is the case, we should keep some cheese in the glove box...I hear cheese goes good with whine. :grin2:

26 degrees. Automatic v6. No steering pump (electric) you can faintly hear the whine. It was a little louder but for some reason my phone kept saying recording failed so I had to restart my phone and the noise got softer....https://cloud.tapatalk.com/s/5c4b2a5c169de/20190125_092117.mp4

Hard to tell from the audio but it does not sound like what I hear. You sure you are not hearing more of a "whistle" sound through the throttle body as the blade is slightly open to run the engine at elevated idle until warmer ECTs?

Not sure. It sounds like the start up of an older tornado siren. Like the very beginning and stays at that tone.

i have been in 4 times for the whining noise. it comes from the oil filter housing which tells me i believe it comes from the oil pump. gets worse over time as far as the loudness goes. embarrassing. they tell me it is normal.

I have the "cold start whine" on my 2018 GT as well. Been there since I got it with 3k miles on it... Seems to be "normal" on the V6's - or at least VERY common. No idea what the actual cause is though.

Just tell people that it's your supercharger warming up. ;-)

I wonder if its the pump within the A8 that whines during its warm up cycle?

Would you mind following up with me via PM? I would like to escalate your situation to a case specialist who can review my notes and determine best next steps at this point. Thank you in advance, hope to hear from you soon!

Here is a post with a recording I made of mine back when I originally got my Challenger - I'm moving around the the front of the car while recording, which is why it gets louder and quieter in the recording....

2019 3.6 engine noise?

Just curious if we're all talking about the same nose...

Interesting as I asked this thread question a while back [a month ago?] and never got a reply.

New 2019 SP Shaker, 2500 miles, and yes, there is a hum which with each gear up [6 sped manual] drops in intensity almost none in 6th. I asked service and now I cannot remember what she said!

Okay, I just called.

Becky in service is a very knowledgeable and fantastic person. It is a "relay" that has something to do with the air intake. Having a Shaker package it is a bit "hummier" [new word?] and of course as the RPM drops in normal driving while the gears go up that humming drops.
It is not annoying at all. Most of my previous cars always had a cold air intake installed and I have experienced noises from whistling to louder air being sucked in and more!
As long as that humming stays consistent she said, it is good. If it starts changing pitch it will need to be addressed.
I want to say it is in a certain way "enjoyable". Engines have always been my music! Ironically this car has a HK 18 speakers system which I rarely listen to unless going from point A to point B on a flat road which these days are and have become a rarity.
I don't worry about the car while having purchased a 7 years 10K bumper to bumper warranty including wheels/tires and keys.

Have a great day...

Your "hum" sounds completely different than the issues being discussed in this thread. The whine noise talked about in this thread is only when the car is in it's "warm up" phase and really has nothing to do with shifting gears, etc. THe while sound that we're talking about is present as soon as you start the car and goes away completely in a minute or two - and only occurs when the car is cold. Sounds like your issue is not related at all.

if you're driving with your windows fully open, you'll notice there's a subtle whistle sound you'll hear from the Shaker as you open up the throttle more aggressively. (mine's also M6, so you hear this going through each gear)

I have had the whine since beginning. It is louder now. 2018 Challenger. Brought to dealership 4 times. All 4 times claim they do not hear it and then day it’s normal. The last time I played a video of the noise and the guy said they did hear that but stated my phone exaggerates the noise. Left hotter than a hatees. If it is normal. Tell me what makes that normal sound? Harmonic??? I put my stethoscope all over the engine and seems to come from the oil filter housing.
