So my local dealership told me this: your vibration comes from the v8 to v4 switch. When it goes into v4 it vibrates and you should put it in two haul mode to get rid of the vibration. Lmao!! You mean to tell me that these engineers screwed up? And their answer to fix this is to
Use your tow haul mode when your not towing anything and also means you would waste gas and possibly screw up your transmission. Hmmm waste gas, that's not what GM is looking for, is it? Also, they said it was my aftermarket wheels. Let's see, when I put the factories back on, it shakes and vibrates. When I put my aftermarket wheels, it almost doesn't vibrate. However, it's still there. So how is it that it's my wheels when it's worst with the factory wheels? I feel like another buy back is coming on!
