Gas Recirculation Valve (egr Valve) problems of the 2020 Chevrolet Equinox

Equinox has 4636 miles and all three times it has been driven in snow a service esc message comes on dash and traction control and stability control are turned off along with awd. One time was highway driving, and other two times on a local street. Also while driving down the highway the dash message said reduced engine power (stayed on for 400 miles/two days) may reduce speeds to 50 mph. Rpm's stared running 1000 higher to maintain speed and fuel economy dropped about 8 mpg. Gm mechanic didn't have time to diagnose but said the turbo was frozen because of temperatures (-10 degrees) and that it needed a winter front and new intake tube. Mechanic said he has seen this problem over 10 times with the same engine that day.

Vehicle completely lost engine response reaction to acceleration peddle from a yield turn into main road. From the yield, slow rolling less than 1 mile per hour, I stepped on the gas peddle to merge into the main road and the vehicle had zero response for nearly 30 feet. If there was a car coming I would not have been able to avoid being completely hit in the side. I pumped the gas peddle in an attempt to regain any response, after several pumps the engine rpms increased drastically to 3000 without upshifting at proper time and the vehicle surged ahead. Odometer reading 2376. 1200 mile service completed. 2400 mile vehicle service scheduled. Filled tank 37. 8 miles prior to event with 89 octane. Roughly 35 to 40 degrees.
