We have a 2013 Traverse with the same squeaky brake pedal. Dealership says that is normal. I told him it isn't normal as I wouldn't have bought it making that noise. Then the other person in the dealership (a woman) stated that it has happened over and over and there isn't anything that they can do for it. Come on GM, I have had Tahoes with 250K+ miles that it never happened in, Silverados that it never happened in, I have a GMC 2500 that it has never happened in.... What gives? It's like fingernails on a chalkboard, this needs to be fixed. The dealership shouldn't be telling people basically "oh well, live with it"
