Hairy, it never hurts to gently take your hand & whack the seams around the spoiler, just in case. And check to make sure it goes up before you take it out on the road!
In the 2 years we've had the Coupe & throughout the snowiest winter on record here last year we've never had a single issue with the spoiler other than an intermittent squeak that went away after a wee bit of WD-40 sprayed on the moving parts.
