I have a 2011 Honda Pilot with good mechanical history. I dirve it about 20 miles a week mostly on weekends. I have had it for about 8 months with 125000 miles. I was out for a drive last week and everything was normal until after I stopped then got back in to go home the check engine light was on and the 4WD light was on in dash. It wouldn't go out of 4WD and revved high as it shifted automatically after I eased off gas to go from first to second. I guess some sensor got triggered. Wondering if it's a common or simple(inexpensive) fix.
