My dealer didn't have a clue.I think my deflector was the first they installed on a Venue. As I detailed in posts before, I had to prove the solution to them. It's really a simple fix, before or after the deflector is installed. If the dealer doesn't want to apply the foam tape to the back of the deflector (not to the hood) at installation, I'd insist that they agree to take it back when it's noisier on the highway. I've never had mine through a car wash but I can't see any reason to be concerned about going through one. Most deflectors fasten to the hood in the same fashion.
