2014 GMC YUKON Electrical System Problems

While driving, the vehicle display screen and lights start turning off and on. The warning lamp says " service trailer brake system" and the vehicle is unable to accelerate at all.

I haven't taken it in to the dealership yet. I looked online and there is a recall called " chassis electronic control module internal contamination" that meets the description of what's going on here, but when I called GMC they said there is no recall for my specific Vin, even though the recall is for my make model and year.
