Ordered a 2021 6.2l AT4 early October, each month get this same message from gm chat: At this time your order has been accepted by GM and will be placed in sequence for production. Presently we are unable to provide a Target Production Week however we do recommend you follow up with your dealership or Customer Care in 3-4 weeks for further details. Sitting at 17 weeks now and no sign whatsoever that this truck will actually be built.
