New to this forum but have a spoiler question.

I seem to have an issue with my spoiler as sometimes it just decides to activate when I start the car. The little red light flashes and I am unable to close it or even use the control button on the center console. If I turn off the car and turn it back on then I can control the spoiler. I have taken it to the dealership twice and they seem to think it functions normally and dont understand the issue. Any good thoughts?
