Bought a 2013 Silverado 1500 brand new with 10 yrs warranty from Rosner. Now truck driver seat doesn't move due to a bad seat assembly and Rosner no customer service tell me to take my truck back broken because they don t have and can t get the seat assembly. Making my truck useless for two members of my family, because driver seat can t be adjusted. A couple of weeks gone by with no update and no other solution from Rosner! Terrible dealer to do business and very disappointed!
