Welcome to the forum AgentOrange. Yours is the first post I can remember about a whistle on acceleration. The noise you are describing almost sounds like a fan belt slipping, which shouldn't be the case on a brand spanking new ride. Open up the hood and have someone else rev the engine for you. Let your eyes do the pointing, (keep your hands out of there!) and listen for yourself. Also pay close attention to your incomming air flow. Make sure all the connectors are nice and snug between the air filter box and the throttle body. I am sure others will post shortly with their thoughts. Good luck!!

You're not alone. I heard it the first time I drove our Nitro with the driver's window down. When I closed the window I could no longer hear it. My wife suggested I drive with the window up.

This TSB won't likely help you out with your R/T. With the 4.0L engine instead of the 3.7L. I recommend you listening to another 4.0L to see if it exhibits the same noise as you have experienced with your service manager involved.You're not alone.

I hate those BS responses from mechanics just to try to get you out of their way. How about "I don't know what it is but we will bring it to Chrysler's attention"?4.0L Whistle anyone?
I've read the whistle noise is a TSB for the 3.7, but my R/T is making a whistle noise around 2k rpm, and it's not wind noise because it does it when I rev the engine while parked.
Anyone else with an R/T notice this?
I'm a little disappointed, I literally just bought the thing 2 days ago and it didn't do this while I test drove it. Also the front of the roof rack bar on the passenger side looks to be warped, and is coming off.

Well I called them today to see how things are going, and they told me the whistle noise is "normal"... I just about started to laugh out of sheer frustration, they said "We had the tech drive the other new R/T on the lot, it makes the same noise so it's normal" :shakehead: I disagreed again and mentioned the TSB for a whistle in the 3.7 and he got quiet for a little, I asked if they could just do the same thing on mine to fix it and he said "Well basically dodge just isn't acknowledging it as a problem on these motors at this point... if we fix it they won't pay us" :smiledown:
So I said "Look, I know how this works... I'll come in tonight to get my car and you'll charge me for the diagnostic time spent looking at something that ended up being quote "normal". I looked at the TSB on-line, I know it only takes a half hour and a drop of silicone to fix this...
at which point he interrupts me "well even so, they won't even pay me for 5 minuets, so I can't touch it"
I told them I will flat out refuse to pay for ANYTHING unless SOMETHING was actually done, fix it and I will pay out of my own pocket "Just fix it, I just want it fixed... what's it going to cost 50 bucks?"
He finally said the tech wants to keep it another day, he wants to find a way to fix it, he's looking into it as best he can, "Don't worry about it, it's not like your warranty is about to expire, who knows maybe Dode will come out with a TSB for the 4.0 soon and you'll end up paying out of pocket for this"
I really could care less if I pay for it... I just want it fixed. This is rediculous...

This cracks me up..."Well basically dodge just isn't acknowledging it as a problem on these motors at this point... if we fix it they won't pay us" and "well even so, they won't even pay me for 5 minuets, so I can't touch it" So Chrysler is perfect now and your dealer can't diagnose if a defect exists, UNREAL!!!Well I called them today to see how things are going, and they told me the whistle noise is "normal"...

It's very possible your noise is caused by the throttle body or where the throttle body mates to the intake, but what if it isn't? What if they do the repair you have recommended and it doesn't fix it. What if they come back again and say its "normal". The dealer can initiate a product report with Chrysler Tech Support and they may be able to help. Hopefully they'll find the cause and you'll be happy.
