Hello All,
i have 2011 C300 that just recently started giving me the light indicators that ESC malfunction , and then cruse control don't work when the lights are on. I am not sure what could be going on but it only happens when i turn left i noticed and it goes off and on

You must scan for trouble codes. ESC alone when turning could be a failing yaw rate sensor or steering angle sensor. But adding the cruise not working with the lights on may indicate phantom failures caused by some unrelated component.

I have scanned with Autel scanner and it doesn’t find anything

!!! This will make the diagnosis much more difficult.
I suspect something common to both problems. Yet it has to be unmonitored by a sensor. Maybe the front SAM or the pre-fuse block or intermittent connection to or from either.
Do you have a wiring diagram? I can’t get to sny of my manuals or WIS right now.

Which Autel scanner? Autel makes a bunch of stuff from really cheap generic OBD scanners to very expensive multi-vehicle scanners.

Anytime something like this comes up, I first ask how old the batteries are.

I have the same car, got the same message today. Stopped, turned off car and restarted, seemed to drive fine for the next 4 hours on the highway. Gas pedal felt like it wasn't giving me full power when I was putting it down. What was the outcome for you?
