This may have been addressed in the hundreds of pages but the part number for the radio module is shared with several cadillacs. Do those cadillac owners have the same issues as we do?

I'm certain that's what GM would like for him to do. If more customers held their feet to the fire, quality would improve.

Theses are multiplex electrical systems and must have a good battery or any number of cascading and seemingly random issues can occur. Get a new battery and stop screwing around with the bad one. Auto store testing is notoriously inaccurate.

I can only assume I'm one of the fortunate 2014 Sierra owners. Has my truck been perfect? Absolutely not! I've successfully worked with my outstanding dealer/service adviser to remedy to my satisfaction to date all the issues I found problematic except for the less than stellar radio.The headlights originally were a disgrace, the Volsa solution has proven to be a safe and acceptable solution for me. The exhaust flapper squeak took two replacements to finally fix that issue. Seat was loose. Had the transfer case and hvac software updates. Had an incarnation of the dreaded vibration issue that thankfully was addressed by replacing one rear tire that had a 30 lb. roadforce reading. Truly smooth as silk now. Heck, nearly every malady discussed here. LOL While I don't like the time and aggravation of working through these issues, my observation is that it's not that unusual when purchasing a brand new platform. I can truly sympathize with you guys and girls who have not been so fortunate and suffer seemingly never ending frustration and disappointment when you should be enjoying your beautiful new truck. Now GM; get busy and fix this sorry ass radio!
