2018 Chevrolet Equinox Electronic Stability Control Esc Problems

I STALLED OUT IN THE MIDDLE OF DRIVING, THE CHECK ENGINE LIGHT CAME ON AND THEN A MESSAGE SAYING THE ENGINE POWER WAS LOW. THE CAR WOULD NOT START OR GO INTO NEUTRAL HOWEVER I WAS ABLE TO PUT THE HAZARD LIGHTS ON AS WELL AS THE RADIO AND ON-STAR. THE TOW TRUCK DRIVER GOT IT STARTED IN LOW GEAR TO GET IT ON THE TOW TRUCK, BUT IT DIDN'T START AGAIN. I WAS ON A CITY STREET IN RUSH HOUR, GOING LESS THAN 15 MPH. I JUST GOT MY VEHICLE BACK FROM SERVICE AT THE MIRAK.COM DEALERSHIP IN ARLINGTON, MA, AND APPARENTLY THE ISSUE WAS: "CAUSED BY: PERFORM SCAN TOOL TEST. THE TECH "EXTRACT CODES WITH SCAN TOOLS". I WAS TOLD THAT IT "JUST NEEDED A SOFTWARE UPDATE". THE VEHICLE DID NOT PROVIDE ANY ALERTS PRIOR TO THE INCIDENT OR SHOW ANY SIGNS OF AN ISSUE, SO THIS IS VERY ALARMING AND A SIGNIFICANT SAFETY CONCERN.

THE ELECTRONIC STABILITY CONTROL SYSTEM KEEPS SHUTTING DOWN, TAKING THE ABS SYSTEM WITH IT. THIS SEEMS TO HAPPEN PRIMARILY WHEN IT'S COLD OUTSIDE. WHEN THIS HAPPENS THE VEHICLE DOESN'T HANDLE OR STOP AS IT SHOULD. MULTIPLE REPAIR ATTEMPTS HAVE YIELDED NO CHANGE IN THE CONDITION.
