I just recently bought a used 2021 AT4 with 28400 miles. After driving 400 miles and stopping for fuel, I noticed the service 4 wheel drive message come up, so I called the dealership and they told me to run by the local dealership and have them run it through there scanner. I told them I have another 400 miles to drive to get home and would take in first thing Monday morning. When I got home the parking message came up. The next morning I noticed that there was transmission oil leaking underneath the truck. Anyone have transmission oil leaking?
