I am an Engineer for a company that is a Tier 1 supplier to Ford, GM & Stellantis, among others, and I can assure you that the Quality control is stricter than ever. You would be amazed about how tightly control contamination on transmission parts now. Also, actual production doesn't start until several years after product launch and they perform lots of builds and testing during that time. The Quality precautions being taken are abundant. IMO, quality is tightly controlled & better than ever.
