Louder than normal engine start up?

[suzukikizashi]

Hello,

I am new here, welcome everyone.

My Kizashi is from 2010, automatic CVT, 4x4.

I bought it two years ago. I am concerned that when starting the engine, there is no longer this nice bass, but it's louder, it's quite an annoying launch, as if I was starting the drill. This sound, like an activated drill, like a whistle, appears when I am accelerating, often at low engine speeds (1500-2000).

Why is it like that? Is it normal? Or something with the engine? With gearbox? With the exhaust system? Is it because my hard drive?

I apologize for the questions, maybe too infantile for you, but I have no experience, I badly need an answer, practical advice, cause in Poland it is not a well known model of Suzuki...and this is my first car in which I fell in love.

What should i do ?

Thank you for all the advice and help.

Paweł, Poland.

Hello

Once the car is started and in gear, I could see how CVT whine may resemble the sound of a drill when taking off from a dead stop. Other than that, I have no idea. Bad alternator maybe? They used to sound pretty bad before they die, but I haven't heard that sound from an alternator in a very, very, very long time.

How many miles and is transmission full checked while running in park ? Have drive belt removed, is noise still there? If it is then your noise is transmission related . A mostly clogged pick up screen would then be your best outcome. If the noise quit after belt was removed ,then rotate all driven pulleys by hand and feel for any roughness from the bearing
