My problems so far: engine sounding like an aquarium filter (GM not giving a rats ass about it), something in the dash or back of engine rattles when you cold start the car, diff being replaced on wednesday, a new exhaust on order, mylink screen is now stuck on a black screen with backup guidance lines on it, car emits rotten egg smell everyday, seats get stuck, etc. My previous GM vehicles include a 2012 GMC Sierra, a 2014 Camaro, 2015 GMC Sierra, and now a 2016 Camaro and I can say that this will be my last GM vehicle. I will be opening a case with GM on Monday and will keep you guys updated. In an effort to document and prove everything, I will post videos and pictures of my problems. Here is what my engine sounds like (note: sound can be heard at every rpm, but is loudest atound 3k)
