I have had the Service 4WD light come on twice over about a year (only had it about a year and a half now), both times at the end of a day on the trails, usually even after running 4H Part Time though today I had it in auto for most of the day, switching to part time after lunch. Like everyone else it goes off after turning off and back on, and Uconnect does not send any message about the warning (though I get an email every time about tire pressure sensors since I air down, duh!) Sounds like I need to pay more attention to using 4H part time since I do forget a lot of the time when we are doing fairly easy dirt roads (with rocks, of course, being in CO).
Before my dealer (Wave) oil change, I removed the oil pan access door (only) from my Artec skids, and there was no upcharge. I was advised to do that when taking it in, and have also been told that removing the skids is not covered for warranty repairs, so there will be a labor charge for that. Vexing but not unreasonable IMO. Dropping the skids is a PITA so am not looking forward to if/when I have to do that.
That said, I had a leaky shock replaced under warranty, and they didn't say anything about the rear LCA skid (no extra charge), so there's that. But that's a bolt-on so no additional work for them.
If I take it to my local 4x4 shop, they charge labor by the hour, and said I could save myself money and them time by dropping the skids before taking it in for any work that would require working through the skids.
