We had smoke coming from under the hood in Austin and then a little bit more while putzing around Galveston. So I made an appointment with GMC dealership in New Orleans where I know we would be for a few days. Our last 2 days of travel to New Orleans the HVAC fan was temperamental…wouldn’t run at all then randomly would start up again. Then in Baton Rouge I got the dash message that said I had 500 miles of DEF left…I figured I’d just have dealer top it off for me.
