My 2016 Sierra has a factory defect of 'GM SHakes'. Your dealership has followed protocol from GM but unable to correct the issue. Until GM can correctly identify this issue I cant recommend anyone purchasing a GM truck.
David do a good dealership

I WAS THERE A SHORT TIME WHICH WAS GOOD.
Very professional and attentive personnel.
Good service, great customer service.
David, my service advisor, was awesome.
