I like posting quick fixes that don't require a trip to the dealer.

SO. If your sunshade ever decides to stay open a bit, there is a simple solution.

Open it completely, then press the buton to start it closing. While it's closing, use your hand and apply a decent amount of pressure... more pressure than my wife could muster. Hold it firmly and eventually, after a second or two, it will go back into the open position, adjust itself and then you're set.

 

Thanks but this issue has already been covered pretty extensively in the following thread, if you want additional info and some cautions about the suggestion.
