ESC warning/hard shifting

[Silverado_19]

Hi all, 

 

I’ve had my 2019 Silverado LTZ 6.2L for a little over year now with 42,500 miles. No issues experienced with anything until today. 

Issue: was driving at speed under 45 mph. Slowed down to a complete stop at stop sign then Suddenly, engine starts making a slight winding noise. ‘ESC disabled’ message appears. check engine light begins rapidly flashing. A “P” symbol with wrench below it appears in orange as well. 

 

OnStar diagnostics sent me this (attached) 

 

afterwards I was able to drive it, however when shifting into gears it jerked slightly but jerked more intensely when shifting from park to reverse. Engine Winding sound still continued. And when accelerating it’s almost like the engine was slipping slightly. Todays Saturday and can’t get it in anywhere until Monday morning. Does this seem familiar to anyone? Any feedback would really mean a lot. Thank you!

some of the canyons had this problem and it was corrected by an updated flash, might be the same for your truck
