Purchased my H3 last week and on the way home got the Diff Lock light coming on AND the Serv 4x4 light also appeared on the DIC (where the odometer is). So, back to Hummer. After a day in the shop with the tech checking the computer, no definitive answer and no fix. Any ideas? I'm over 3 hours from the dealership and I'm expected to bring it back, again.
