Does it sound like this? http://www.orangefreesounds.com/dog-whistle-sound/
Just checking in, how loud is this noise? The video isn't very clear.
I have a whine that is audible at higher speeds but is dependent on the throttle position in each gear. If the engine isn't in power making mode, meaning it isn't growling and revving really high, I can depress the gas pedal and release it and create a whine that changes in frequency slightly. I always thought it was the sound of the engine when it was trying to be fuel efficient but now I wonder if it is this.
I have a 07/2012 build date. Don't want the transmission to have problems later in life, I'm at 45,000+ miles.
I have a 2016 CX-5 and it's making the same noise I think but the dealer says my car is too new and the problem shouldn't occur on 2016s.
Here is a video I took of the noise, it's at night and I held the phone up while driving so I was paying attention to the road.
Please let me k ow what you think

Although it's for older CX-5's, but we've still seen a few of newer CX-5's having similar noise issue and the transmission got replacement under this TSB. Use this TSB and be persistent asking the rep at Mazda North American Operations to replace your transmission under warranty:⋯ I have a 2015 Mazda CX-5 FWD w/ 45k miles. About 2 weeks ago, it started emitting a very high pitch noise (~6.5khz) after I have been driving for 35+ mins and if I travel 35+ mph. The noise is constant, except for random 1-2 second breaks. The noise is independent of rpm or wind direction. However, the car starts making the sound quicker on warmer days.
Whining Noise From Automatic Transaxle 2012-2014 Mazda
oemdtc February 27, 2016 Repair Tips
APPLICABLE MODEL(S)/VINS
2013-2014 CX-5 (SKYACTIV A/T) with VINS lower than JM3KE2BE3E0415164 (produced before November 11, 2013)
Whining noise from the automatic transaxle when driving at 10 mph and above.
The noise:
Depends on the vehicles speed only (the more speed, the more noise)
Occurs with all types of driving (acceleration, deceleration, steady speed)
Does not depend on rpm, gear, or ATF temperature
This is caused by a damaged bearing in the transaxle due to improper configuration of the transaxle case.
A modification has now been implemented on automatic transaxles with the serial number 3TR1111680 and higher or 3TD1104906 and higher.

REPAIR PROCEDURE
Replace the 6AT assembly with a new one according to MS3 online instructions or Workshop Manual section 05-17.
Hey. I have a 2016 Cx-5 that has the same problem. The whining noise is audible around 20 mph to 60 mph. At first, I thought the car got louder due to the aftermarket window deflectors. I took the deflectors off, it still persisted. Then I thought it was the road noise because of the tires getting wore out. I took it to the dealer and they said the same thing. However, I tried to listen to it very carefully and realized that it was not the road noise because the noise is not associated with RPM or road surface. It occurred solely according to the speed of the vehicle. I took it back to the dealer. At first, they denied it. However, I insisted that one of the service adviser heard the noise last time so they had to have somebody else test drove it again. In the end, they admitted that they heard it and would like to look further into the problem. They found the noise coming from the transmission a few days later and ordered a brand new transmission for me. The new transmission was installed and the car is now quite again.
I hope this could help you guys who have the same problem.
Hi everyone. I am having the same problem with my 2016 CX-5. I noticed it last week, and I'm still under 13,000 miles. Thanks to this post, I've determined that the sound comes on above 27 mph, it's audible outside the car and appears to be louder on the right side. We also determined that we believe it's a mechanical issue, as we turned the car completely off while driving and the noise still persisted. The noise is steady, loud, and doesn't change with speed. It also starts when the car is warmed up, so it maybe takes 15 minutes for it to start.
I am taking the car into my local dealership tomorrow. Will report back on the solution. Thanks to all posters for helping me not feel crazy about this noise!
Glad to hear they actually made a genuine repair instead of replacing the entire transmission. I always felt mine was seal related, but the powers that be opted for a trans replacement. At least you know that it was something simple.FOLLOW UP: After a week in the shop, I just got my car back. It took a bit for the technician to verify my problem, but after a few test drives, they did finally duplicate the 'high pitched dog whistle' sound. Mazda determined that the cause was Axel Seal Failure. They replaced the seals (a whopping $7 each!) and re-lubricated. Everything was covered under warranty.
Hoping this solves my problem for good.
