I have 2021 Silverado Custom I bought in October (delivered in December). A couple of months ago every time I hit a bump the traction control indicator would show that it was off. Like to drove me nuts when I was off road because it "dinged" every time. Then before I could get it to the dealer the check brakes light, air bag light and a few other warning lights started periodically going on and off. Turned out to be the brake sensor. They replaced that and it's been good ever since.
