My 2016 Canyon Duramax has been in the shop for 114 days. Started with turbo wastegate rod falling off, various sensors failing, intercooler issues and now severe turbo lag with no codes showing up. So there is no best guesses as to the issue. GM has been great trying to fix it. I have a loaner so I’m not out any cash other than some repairs I had to cover that did not resolve the issue, whatever that may be. However it is concerning that GM cannot return my truck in working order after such a long oeruid. Anyone else experiencing unresolvable baby duramax issues!
