How are you?
In one of five 20V31SG sufered a damage in one cylinder head. Motor was tripped by “Cylinder in CCO mode”
An inspection was performed. a Crack in cylinder head of one cylinder was found. After that, the inspection was deepened and the following issues were found.

Could you please let me know if your motors continue with these issues about cracks? Did you received any feedback from manufacturer?
