general problems of the 2018 GMC Sierra

On the morning of oct 26, 2020 @ 845am. . . I was heading south on 287 in mansfield TX. It was raining hard so I was only going 60 mph. The car in front of me was going 55 or so. When the rain and wind picked up, the car in front of me abruptly hit its brakes. That's when my truck brakes locked and I began sliding or being pulled to the right. I was in the left lane on the 2 lane highway. Had it not been for god and me, not panicking. . . I would have crashed! my truck fish tailed twice while I was trying to apply the brakes but. . . I couldn't stop. I almost put the truck gear in neutral but it was raining so somehow the truck managed to slow down going up a small hill, giving me control back. There were 2 other cars that seen this. I was a nervous wreck! I immediately got off the highway and went to the first gas station I saw and thanked god nothing happened. The problem I have is, what if my family were in the vehicle? how is it that gm is allowed to sell these vehicles? also, I searched almost every website and included my VIN. . . But every reply says my truck is ok (until today). I haven't had this truck for a year yet. But I'm ready to trade it in. I don't feel safe at all. I almost want to get my truck towed home. Why put people lives in jeopardy?.

Certain 2018 GMC Sierra 1500 denalis were issued a recall for the "electronic brake control module". For my VIN, it doesn't show that that issue needs to be fixed (I just purchased this truck last week), but it indeed does. When coasting at a low speed on a small hill, brakes almost feel non existent. GMC recalled many of their vehicles to get this issue sorted out with a simple, "software update". For some odd reason my GMC's VIN wasn't up for a recall when it clearly needs one, im pleading for some help; I'm worried for my safety because of this manufacturer defect. Any help is appreciated, thank you.
