Took my 2016 Silverado Double-Cab 4x4 (65K miles) in this morning for the infamous "shake". Driving home from taking my daughter to college on Sunday it got so bad I had to stop to make sure I didn't have a loose tire or something. Long story short, dealer said the Torque Converter has failed, it needs to be replace along with several other parts (know issue with a TSB). Issue is they have another truck with the same issue that has been waiting several weeks for parts. My dealer has been great, providing a loaner, etc. My frustration is with GM, they have a known problem and parts are on an extended back order. Dealer said its covered under my Certified Pre-Owned 100K powertrain warranty, however I won't have "my truck" for several weeks. Filed a complaint with GM they said a Senior Advisor will get back to me and my dealership if they are able to help. I have been a Dodge guy all my life, bought the Silverado in June of 17 with 18K miles, based on this experience guess I will have to look at other brands for my next truck. Sorry to vent.
