last month i purchased a new 07 TL-S..when i am cruising between 65 and 75 miles i hear a high pitch engine whistle..cannot hear before 60 or after 80 miles..i took the car to the dealer and they told me that is a normal noise of a type S..
are you guys that own the type S experiance the same thing??thanks.

 

whistle? doesn't sound normal to me, try and switch the vents closed, or it could be misaligned hood

definitely not normal

 

thanks for the reply...i will try that..
it sounded strange to me when they told me that's normal..let's see

 

blow off valve too bad its not in our TLS, no turbo.

Don't you love dumbasses at the dealerships?

 

its your turbo spooling duh.

 

what do you mean by the blow off valve??

 

Its a pressure relief valve for a supercharger. Lots of time a high pitched whistle is a leak someplace in the intake system

 

i don't think it's the intake..it was doing this noise with the stock intake and it's doing it now with an aem cai..i forgot to mention that when i am going 70 miles and i heas the whistle, if i let go slightly of the gas pedal for a second the noise goes away and the moment i put my foot on the gas pedal the noise comes back..

 

it has to be from the intake then

 

time to invest in a CAI imo ;-)


god damn it everyone's avatar shows the metallic stripe on the front bumper lower grill...did EVERYBODY just take their bumper off and use the chrome strips?!?! >< god damn it



whistling sound is most likely your intake if the "rest of your car looks normal"

 

the whistle was there even with the stock air intake system...

 

Never heard it on mine. Although I don't cruise at that speed much - more city driving.


Do you have the P2R TB spacer by chance?

 

no..sorryyy

 

My wife's VERY stock Jeep Liberty does the same exact thing. I have no clue what the heck is whistling like that. It comes and goes with the gas though like you said. To make the noise stop, let up on the gas a bit, step on the gas the noise will carry on longer. Yep. Sucks, no clue what it is.

 

my aem cai whistles, thats about it

 

I have a similar issue on th 02 TL-S, when I am at constant speed in between 55-60km/h, I hear a whistling noise which goes away as soon I take the foot off the gas or I drive outside of the 55-60km range by either accelerating and decelerating out of that range, please let me know if you find out what that is, I don't have any aftermarket intakes in the car.

 

nothing so far.. took the car to a second dealer, i drove the car with a technician who told me it sounds like there is something wrong with the tranny and that he would have to run it by his manager..
1 hour later the verdict was out..normal characteristic of the type-s..took my car and left the dealer..i was so pissed...............
