Jumping on the bandwagon here. I have a 2014 Sierra SLT Crew Cab that also has some terrible rust. Waiting for 4 months to get in to my dealer to have the TSB work performed. Pics in my gallery. This is unacceptable. Any class-action lawsuits out there? Emails to Mary Barra? or Jeff Luke the lead engineer on these trucks. What a joke. I was torn between Ford and GM. Should have went Ford.
For those that have had the repairs done - are you happy with it? any further rusting?
