Hi all,
We have just purchased a 2018 Automatic CX-3 Petrol 2WD.
I am enjoying the handling and surprisingly nippy performance very much.

However, one thing that concerns me is a thump/clunk noise that I hear...

I brake at a say a traffic light or junction
The iStop engages and the engine goes off
When ready to move off, I release the footbrake.
The engine comes back on and around the same time as I move off, I can hear this clunk or thump.
Is this normal?

Our current/previous car is a Merc B180 which also has a similar stop/start feature and I don't hear any similar noise under the same circumstances.

Thanks in advance for any replies!

I have the same noise with mine, although I don't really notice it.
I have the same model as you 2018/2019 2WD Auto.
I can't say weather it is right or wrong, but it has never caused me a problem.
I am glad you are enjoying the rest of the car..

Take care.

Mine doesn't clunk. Or not that I can hear. The only noise is that of starting.

I have the same chunk. It comes from the brakes. Try to move your feet off the pedal slower.
