Dreamss Posted July 12, 2011 Report Share Posted July 12, 2011 (edited) Hey Everyone, Im heading over to the dealer to try and fix a problem I've have since i took ownership of my car. I've been there once before about this but they claim to not hear the noise... Here is the notes i am handing to the dealer tomorrow: The car will randomly make a “scratching” / sound while the accelerator is being pressed (or cruise control engaged) while driving on the highway at speeds approx. 80+ km’s / hour. This noise also sounds like a "snowy" channel when the tv cable is unplugged. This happens on almost ever occasion with the exception of a few times per week, if that. The sound is not extremely loud, but annoying as hell and could be heard over soft music easily. This noise will shut off once the gas / throttle is released. I am ruling out this being related to the TSB # 11-2-13 (wind noise due to side mirror) as it will ONLY happens while accelerator is pressed / throttle engaged. If I release the gas the noise stops immediately, if I re-apply the gas it comes back on…I can make it start and stop the noise simply by engaging the throttle. I have tried to identify where this is coming from and it certainly the front of the car, left side, behind the dash possibly. This noise has been haunting me for months now, i just haven't had the time to bring my car in unfortunately to deal with it. The killer was last week on my 18 hour road trip vacation, I had to listen to it all 8 hours driving there and back, i finally lost it and am taking some time off work tomorrow to being it in. Just as an fyi...i did the mirror fix with the foam insert and this noise still happens, I'm ruling out it being the mirrors as this noise will not appear at any speed unless the throttle is engaged. So, the noise ONLY shows up when I am pressing on the gas, or the car is on cruise control, it starts up between 70 and 80 km's per hour and will immediately disappear when i release the gas. It sorta sounds like air, but at the same time it doesn't..it sounds like rushing water, snowy channels, and best word to describe it is "scratchy". It is not coming from the radio as it will do it with the radio on or off. I tried with different setting on the heater and a/c and it still shows up regardless. I read someone mention something about a cracked evaporator on their car causing noise...could this be a possibility? Any help that i can bring it to the dealer with regards where to look or anything that may help would be really helpful! Thanks!

Have you taken a look at the hose leading into and from your air filter? Maybe something like a leaf got stuck in the opening of the intake and is making some turbulence when the throttle gets opened. Quote Link to comment Share on other sites More sharing options...
Dreamss Posted July 13, 2011 Author Report Share Posted July 13, 2011 Thanks for the reply, i appreciate the feedback!! I'll mention this to my dealer who currently has my vehicle in for 9 other issues along with this one, (i have a lemon) and see if this suggestion helps any. Just curious, let's say this is the case or something similar, why does it only start at 80 km's an hour, and almost exactly to that number? Wouldn't the throttle be just as open at lower speeds while accelerating or higher rpm's? Today is Tuesday, i wonder if I'll even have my car back by Friday Any other suggestions welcome for this noise I'm hearing should anyone want to suggest something different. Thanks!!

I would think that below that speed, the airflow is not great enough to cause the sound (at least not to audible levels). Or at that speed, a harmonic resonance occurs where the sound is amplified. (just theories) Quote Link to comment Share on other sites More sharing options...
wilsons66604 Posted July 13, 2011 Report Share Posted July 13, 2011 (i have a lemon) Good Luck DreamAss!! I hear ya. I'm dreading the trip to the dealership to have my BAMR fixed (along with a new update, if any, to MFT). It has gotten really labored at trying to close and I don't think it's due to cold weather in KS. Quote Link to comment Share on other sites More sharing options...
