Update: Fm worked fine at dealer today so working as normal was the response I got from service writer. They checked everything according to service writer. The truck was moved a total of 1km from the time I brought it in so it was not road tested. Anyway, worked fine for the drive home maybe they tightened something not sure but time will tell. The led issue was also looked at. They involved gm and gave me a case number. said some trucks work and others don't. Service writer said this is the first truck to have a complaint about this. I asked" first at this dealer" and he said no first for gm. I laughed and said this is a well known problem and certainly not the first time gm has heard this. I am in canada by the way.
