They are changing them.Has anyone actually gotten theirs replaced yet? I've been calling dealer, they don't have - don't know. Called dealer's "Customer Experience Manager" - never got a reply, what a waste. Called GM Customer Service, have a Service Request Number, bumped to a supervisor, was told I would get a call back within 2 business days - it's been nearly 4 weeks and no call, despite leaving a couple of messages during that time.
I'm beginning to wonder if anyone is actually getting a replacement for theirs yet or not. This seems absolutely ridiculous given that the recall was months ago, they have a replacement (changed over halfway through 2018 model year - if memory serves - mine's a 2017), so its not like they have to go to the drawing board to figure it out. It's a production issue, and I have a hard time believing that a cord with heater block attachment is that hard of a thing to produce/procure in sufficient quantities to satisfy current production and the recall.
Mine was done a few days ago.
Lots of others have also posted about completion.
(fwiw, I didn't have the cord cut on mine -- just waited til the parts were in for replacement)
