I'm having the coolant light problem as well.

This time is even worst, when I reach >6K rpm, coolant goes on which is expected.

Then the computer stalled my engine suddenly. After a few seconds, when the coolant light goes off, my engine is alive again.

Does anyone experience this before?

 

Hey Berik, I had a similar, less severe issue with the coolant light. Run the car up to 7 or 8K and begin cruising; coolant light came on. My engine ran normally, light went out, no further issues. A second occurrence and the dealer replaced the coolant tank and sensor (my car still under warranty)

 

Don't know if your case is similar, but several people on the forums have experienced this:

Hope your problem isn't serious, and good luck getting it fixed

 

stalling is not associated with the known coolant sensor issue as far as i know.
