I am waiting on a sensor for the DPF it has only been a week since I drove my brand new HC Tahoe off the dealership, never made it 20 miles before Emissions system fault came in then right back to the dealership. When I start it thru the start stop button even in a heated garage 60F the steering wheel heater comes on and also only the driveside heated seat comes on, neither of these should come on. I hope my list doesn't get too long for when it goes in for the sensor replacement.
