[HUMTECH]

I dont know about the US but in Canada any Hummer repaired under warranty has to be done at A Hummer dealer unless the repair is deemed an emergency repair, in that case the non hummer dealer doing the work has to actually call the nearest Hummer dealer and it is set up as A sublet repair through the Hummer dealer. Big pain in the butt. Off warranty take it anywhere and any dealer should have no problem working on it unless there are any hummer specific tools required for the job as only Hummer dealers have these tools shipped to them as essential tools.
