nope didnt say why it happened. Not sure how often it goes into v4 mode. A gm rep came out tuesday and rode with me. Said hes gonna put a set of new michelins on it and it should tAke care of 80% of my problem. I said what about the other 20%. He told me its the characteristic of the truck. I said ur kidding me right?!.... Anyways ill see how it rides with the new tires. Still gotta get them to fix the vibration on hard accell from a dead stop. They said that was Normal too.. ****ing gm... Excuse my language.. Im just fed up with them insulting my intelligence..
Tires had nothing to do with the failed lifyers right?
