Update, truck is still at the dealership. I dropped it off last Thursday. I hadn’t received any updates from the service department since I dropped it off, so I called them yesterday to figure out where they were at in the service process. I had the truck in for 3 issues: Leaking sunroof, rough 3-4 and 7-8 shifts, and the rattle on cold start. I was told they fixed the sunroof (debris clogging the drain tubes) and the transmission rough shifting (TCM flash/update). The service writer told me they were waiting on parts to finish the truck, but didn’t have specifics on what parts exactly. I’m assuming they are the new updated cam phasers to address the cold start rattle. Kind of frustrating that they didn’t give any update until I called them after being without the truck for a week. However, I’m glad it appears that they are making progress in the right direction.
