South Carolina | I have a '23 AT4 and the fuel mileage around the farm was 18-20 and 24-28 highway. However........ mine has spend the better part of 3 months at the dealer waiting on parts. First the turbo went out and that was a 6 week wait for the part. Drove it for a week and the truck started running hot. Coolant control valve is bad and the truck has been parked at the dealer for 6 weeks waiting on a replacement valve. No scheduled ship date for that part. We finally went over and cleaned out the truck and moved all of my tools to a different truck. GM customer service says they will provide some relief. 46K miles. I like the truck and the fuel mileage can't be beat but parts sourcing has soured me on the 3.0 . | |
