cooling flap comes out at 170 knots

Hi All,
On my new 14 I've noticed that the engine cooling flap comes out by about an inch as soon as I exceed 170 knots. Above 180 knots the force on the knob controlling the flap is so strong, that I'm unable to close it. Need to slow down to close it, but as soon as I accelerate the flap comes out pushing out the control knob. Looks to me, like the locking mechanism is unable to handle the pressure generated on the flap during high speed flight.
Anybody experienced similar problem?
 
Mine has a good bit of pressure but I have not noticed it to open on its own. Although, I don't think I have had it fully closed at that high of a speed. I am limited at the lower altitude with the flap and can close it only high when the air is cooler.
