Frustrated Recall Fix?(Don't know the recall number, yet)

I was called by my dealer to bring my 2017 in for a free oil change and annual inspection, before the 1st year was up. I agreed as I was planning on it anyways. I was told that there was some recall that needed fixing as well, and it could be done at the same time. OK.
The time came I took my car in, when I checked it in, I was told that there was 2 recalls, an emission recall and something else.
When I went to pickup my car, I was told that the emission recall wasn't fixed as they had to order the part in. You think if I made an appointment that they would order the part in.
Anyways 2 weeks pass, and the dealer phones and tells me the part is in. I make another appointment to fix the emission recall, 2 days before a long weekend.
First day, they haven't finished it yet.
Second day(Friday afternoon), they can't get any power to the engine to run an emission test, they will need to keep it until Tuesday. That evening I thought don't they know how to use Hold mode?
Day 3-5, long weekend.
Day 6, I call the service adviser, and he tell my that the dash lights up, but there is no propulsion from the engine or battery. The have gone over what they have done several times, reprogrammed and updated all of the modules and still no propulsion. As it sits now(literally), the are in talks with 'GM', to see what is happening.
They say the have done a few of these recalls before, without any issue. I am the lucky first to have them scratching their heads. At least I have a loaner car, but it is a real pain having to purchase gasoline for CAN$1.30 litre.
Has anyone else had this emission recall? I was told it was new. ???
