I am loving my new 2023 CX-5 Turbo. I’m at 1,800 miles now and so far I have been very satisfied with making the jump to Mazda. However, there is a slight buzzing like sound, almost a super fast click, that is coming from the engine bay somewhere. It changes speed and pitch with the engine, so it is coming from something that is being driven by the motor. I’m not sure if it is some sort of pump, or pulley, or something of the sort. It is pretty faint, but seems to be a little louder than when I first heard it. It could be something perfectly normal, but I thought I would run it by the folks on here before pointing it out to the dealer. It’s definitely not the tranny but it is similar in sound to a tranny whine.

Very faint high pitched "mosquito" sound
My 2019 GTR (only 160 miles) started producing a very faint high pitched sound today in the cabin.. It almost sounds like a mosquito. I notice it when I press the accelerator and when the car is at a standstill. It increases when I press on the accelerator and dies down when I let go of the...
New CX-5, high pitched whine at 80 km/h (50 mph)
I recently bought a 2021.5 CX-5 GS AWD. When driving on secondary highways, I noticed a high pitched whine when the vehicle was going at 80 km/h (50 mph). The sound is distinct but is not particularly loud, i.e. you can't really hear it with the radio on or if the ventilation fan is above the...
This seems to be related to the high pressure fuel pump. The vibration is getting through and into the cabin. Its normal but really annoying. Some people were able to resolve or greatly diminish the noise by adding insulation but I havent found any pics which show where it was added.
Interesting, my 2022 has been producing the same buzzing sound from the very first day.
I noticed this buzzing tonality or pitch changes with the speed of driving. In other words the higher speed you have the higher buzzing pitch is produced.
Does the fuel pump work harder with the speed increase? If yes then this version can be more realistic.
