Was driving my brand new 2020 Chevy Silverado, Crew Cab, LTZ with 6.2 engine with 750 miles on it, owning it less than 30 days, and all these lights started flashing on dash. The vehicle started sliding all over the place, while I was trying to steer it, though I had it in auto 4x4. I almost hit a tree due to not being able to steer or stop the vehicle. Luckily there was a snow bank. I had a hard time stopping the vehicle, like the brakes wouldn't work. The lane assist light turned off on by console. I didn't know what was going on. I was on a snow covered, dirt road but, traveling less than 15 MPH.

Then the next morning, when I had phone signal, I noticed I had two emails from OnStar that stated I had a diagnostic alert for "Antilock breaking system" and another email with an issue "StabiliTrak stability control system". Needless to say, I spoke with dealership on Monday the 27th and vehicle is set to go to dealership this Friday 1-31-2020.
