Hey everyone it's time to get real with gm, I'm looking for people that want in on this upcoming class action lawsuit. I have a 2015 Sierra that have the tapping/knocking noise. I discussed with gmc, they played me off. The dealer did a #7 injector & lifter Replacement job, that they screwed up. But I got that A$$ Now. I don't trust gm or the dealership. But, if your vehicle has that noise, then you need to inbox me at [email protected]
