I think the QC issue is BS. No company would let 200-300M of inventory rot for regular QC - its a nice positivised way of saying "missing parts". If it was just QC, they would have sent guys payed time and a half to get some done a long time ago.My dealer said exactly same: “Spoke with GM. There is a bottleneck in quality control. They were able to give me an ETA. Sorry.”
I assume they meant to say “weren’t able to provide ETA” because that was the entire message.
