While going to LA from Sacramento I noticed that while at 70 mph there is always a whistling noise when you are stepping on gas and when you take your foot off the gas it stopped.

Its annoying and defeats the purpose of buying such a high end SUV and instead of less road noise you hear whistling sound.

I took it to dealer for diagnostic and they stated that its either from engine or from transmission and they have no solution to it and you have to live with it.

I did not spent $50K to hear that noise.

Update from Apr 25, 2016: This is update from last time when Niello Acura could replicate the noise but there wasn't any solution to it.

I called Acura HQ and they set an appointment for Acura Tech-DPSM on 04/21/2016 to drive and next day I get call back that they could replicate the whisling noise but the same noise also came from other 2014 model they drove.

So there is no solution to it.

The same response I got from Kristine from Acura client relation.....

I hope Acura find some solution to it as I am stuck with this annoying sound.

Niello Acura sold me a new 2014 Acura MDX on June 25,2014 for $48,000. At about 1,500 miles a Vibrating Whistling sound started coming from the engine. Their service dept said there are other 2014 & 2015 MDXs with the same problem & they CANNOT fix it. Apparently, the Acura engineers have no clue what the problem is on this newly designed MDX. They think it might have something to do with the fuel pump. The dealership told me: "Do Not Bring Car Back To Service Because We Cannot Fix It". They told me to drive the car with my windows up, so I wouldn't hear embarrassing, whistling, cricket noises.

So now I guess just everyone at the stop light & in parking lots can hear me coming! Isn't it illegal or fraudulent for a car dealership to knowingly sell cars with problems to unsuspecting buyers??? Where's MY protection? The dealership said "no one had died from the noise & I would get use to it"... Buyer beware!
