Re: Light Throttle Whistle / Whine - V6 / QuadraTrac I - With VIDEO

Palmetto,

I was wondering whether you resolved the whine issue with the dealer?

Re: Light Throttle Whistle / Whine - V6 / QuadraTrac I - With VIDEO

Curious about this too....

I have V6 QTII and I get a whine similar to yours at light throttle tip in. Have asked the dealer to check it out on my previous two visits. I always come back to find the "could not replicate..."

Anyway, I have slightly over 16,000 miles and I have noticed this since probably the first month. My whine is not as loud or pronounced as yours however.

I think it has to do with the transmission. I can get mine to whine for about 1 second when shifting from N to D while idling at a standstill.
Give it a try and see if that happens with yours as well.

-Jay

I also have whining noise comin from the front end It seems I can only hear it when I hit speeds over 60 mph. I went to one dealer today and he said its normal and didn't even bother checking anything else. Anyone get there's fixed yet cause I have another appOintment with a different dealership tomorrow

Re: Light Throttle Whistle / Whine - V6 / QuadraTrac I - With VIDEO

I haven't really had any contact with the dealer since the last time. I've been pretty tied up since then, but I will say that I don't notice it anymore. That may just be because I haven't taken a trip since then and perhaps my commute isn't long enough (25 - 35 min).

I'm coming up on my first oil change and plan to bring the issue up then.

As for transmission as cause - the service manager was confident that to the extent there was/is a noise, it was gear whine from the transmission.

Similar issue. During early acceleration at each of the first two low gears, I hear a two second whining/whistling noise. Much louder outside the car than inside. Thought I was hearing things until one day was standing next to the car when someone else was pulling it into my garage and noted it was pretty loud. Now the whole family notices it. Seems to be only once engine has been running for awhile. I do notice it during highway driving as well. No performance issues noted. Does not seem related to use of A/C since I have been noting it during the winter and without the defroster on.

None of the TSBs seem to address this exactly, although the one about whistling and the HVAC system may be similar. Any thoughts before I bring it in and hopefully am able to reproduce it for them? About 5500 miles on the car. Interestingly there's an old TSB 09-001-07 from 3/14/07 for the WK jeeps that I found searching online: "This bulletin involves applying a thin bead of RTV to the intake manifold-to-throttle body joint....The customer may experience a slight ** high frequency (pitch) ** whistle-like sound while
driving. This sound is not loud and may not be noticed by most drivers. The sound can
occur at any ambient or engine operating temperature. The whistle-like sound is most
noticeable under load, with a light throttle, and between 1,200 and 2,000 engine RPM's."
