Has anyone heard of the dealer being able to 'reflash' the car's ecu to get this shade to work? If so, approx. what's the charge? Thanks.

When you say your rear sunshade is "not working", what do you mean? The rear sunshade on my 2013 "hangs up" and won't deploy unless I wiggle the drivers side around. It always retracts. I can't figure out how to keep it from hanging up, but I never thought it was ECU related.

By "Not working", I mean that use of the switch on the console will not cause the shade to go up or down.
