Just curious your thoughts before I take it in my first service..2024 6.6 gasser
intermittent issues
1. On some startups - brake pedal kicks back hard once motor turns over
2. Belt squeal
3. Intermittent hard downshifts, especially at low speeds in traffic
4. Wireless CarPlay works fine most startups, then just won’t on others
5. Lastly, no an intermittent issue, but a one time issue. Truck stopped in reverse, bumped 4lo button, message in dash to shift to
neutral, pushed 2hi and message went away, drove off but during a short couple mile trip, heard grinding on slow turns, sounds like from the area of front diff
Any constructive feedback before I take it in and get a bunch of “could not replicate” at the dealer?
