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.
Had bed liner installed. Very good staff and installers.
no problem ,had a app at 10 and my truck was taking in right away
Updated status frequently
Dave was great and very helpful.
Your team are very professional
