Our 2009 EXL with 23,000 miles occasionally seems to get "stuck" in 3rd gear. It only happens every so often. Happened about this time last year and a couple of time during the winter, not at all in the summer and again yesterday... Only happens when it has been sitting at my wife's work all day. I thought perhaps she was accidentally hitting the D3 button but after much fiddling with it, I cannot see how she can accidentally do that - and she is sure the yellow light indicating D# is not on... Didn't throw any codes last year and seems to solve itself if you stop, put it in park and put it in gear again....
