2021 6.2 Silverado in shop with 0 miles from me yet.
Ipurchased a 2021 Silverado 6.2 LTZ Z71 2.5 weeks ago and traded my 2018 5.3 in for it. They've replaced the ECM, oil pump, some sensor and they are still getting a check engine light. All of this is still before I took delivery of it. As of today supposedly a GM engineer is coming out to look it. I am really discouraged in the new product
