I'm thinking that, they prayerfully caught whatever issues on their time and they get them resolved and I can take delivery and have some piece of mind. Wishful thinking.
I purchased a 2021 Silverado 6.2 LTZ Z71 2 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.
