Update:
Dropped the LR4 off this morning and just got an update call from the dealer. Something "went bad" in the battery and they are replacing it under warranty, charging system checked out okay, and the window switch issue is unrelated; needs to be re-calibrated and that is something they would show me how to do if it ever happened in the future. That, and they said I should flush brake fluid and power steering fluid for $259 each. Ha!
On a side note, I saw the "Range Rover" key fob being handled from the loaner car desk before doing the paperwork and asked if it was an Evoque, to which the clerk said "yes" in a somewhat positive manner, like I should be appreciative (really hate those things). I asked if there was anything else, perhaps a Discovery. She said there was but would a full-size discovery be okay and then apologized it was only a diesel, lol. Much better choice than an Evoque or Disco Sport.
