Business ProfileforPaul Masse Buick GMC South, Inc

I have a 2016 GMC Acadia with less than ****** miles that I bought brand new from a dealership. The check engine light has come on multiple times in the past 6 months. I brought it to **** Masse in June 2023 and hooked it up to the diagnostic. They did not know exactly what was wrong with it, so they fixed a bunch of things which cost me $2,200. 3 months later, the check engine light came back on again. This time they're telling me the repairs cost $3,725 and it's related to this bulletin (***********************************************************). I opened a case with GMC corporate to cover the cost since it's a known issue with the vehicle. I have called every day to come to a resolution, but there is zero sense of urgency. I've been without my car for 3 weeks and just now, they're telling me that my car VIN is not covered under that bulletin, so I need to pay for it out of pocket. None of that makes sense because they are using the bulletin to diagnosis and fix the car. Corporate said if my VIN was under the bulletin, then it would be 100% covered. The bulletin says ALL VINs are covered, but they aren't honoring it.
