Turned car on (in driveway) and service esc light came on. traction control, stability control, and driver front and lane assist all disengaged. unable to manually turn back on through steering controls. stopped the vehicle, parked in a parking lot, and turned on and off multiple times and the service esc light was still on. drove to destination with the service esc light still on, turned off vehicle, waited a few minutes, turned it back on and the service esc light was off. contacted local chevy dealer's service department. was told to drive around for a couple more days and see if the issue returns. if it does return after a few days, recommended to schedule service.
While driving, the tires felt like they were being locked up to keep from fishtailing even though roads were clear and dry with normal acceleration. after driving, parked vehicle and sat in it for an hour. afterwards, turned vehicle on and the screen stated to service esc. stabilitrak, lane assist, and parking assist light came on. after a couple hours with the vehicle off and drove a block, the warning lights turned off and became normal. then after an hour of the vehicle sitting and turned off for an hour, we began driving on the highway, after an hour of driving, the screen stated to service esc again. stabilitrak, lane assist, and parking assist light came on again.
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.
