High-pitched Noise While Moving Quickly
When you accelerate, your Mazda CX 7 may make a loud noise. This suggests that the stator belt may be the cause of your issue. You must determine if this noise appears suddenly and whether it can end the same way it began.
Although it is less important than the timing belt. The stator belt is a worn component. And that is utilized to provide electricity.
Electricity goes to the secondary parts of the engine in your Mazda CX 7. If it breaks, however, engine problems may result. The tensioner blade or its deterioration may be to blame.
This noise is also a sign of a slackened belt. In any event, inspect your belt’s condition and tightness.
Creates a Whining Sound While Accelerating
Sometimes you may hear turbochargers whistling or rattling sounds. It’s probable that your Mazda CX 7’s turbo is deteriorating. And many of its components are getting towards the end of their useful lives.

You may feel as if CX7 makes a louder noise while accelerating the faster you go. You need to consider the rolling portions of your car. In fact, this loud noise doesn’t really come from the wheels.
Also, not from your gearbox, it is most likely coming from your transmission. Your bearings are the most likely culprit. So be careful to inspect them to rule them out.
As the source of the loud noise, you hear while you accelerate.
To sum up, your Mazda CX 7 makes a noise while you accelerate. And the noise, which may sound like clunking, stops when you disengage (push the clutch pedal).
One of the worn elements in the clutch pedal may be to blame. In actuality, the gear release bearings need to be changed every 120 000 to 130 000 kilometers. Simply check to see whether shifting into a different gear is harder than normal for you.
If the clutch pedal seems completely devoid of resistance. Visit your technician to have the clutch release gears on your Mazda CX 7. Replace it if you experience any of these signs.
