Strange indeed....Wishing you a solution soon.

Might it be the lane centering feature? Using it, are you?
In that case, try disabling it and seeing if it helps.

It is necessary to remove the bumper and OEM trim before installing them. The entrance appears little incomplete without the trim, but it will undoubtedly have a more aggressive appearance. It was somewhat similar to my setup for a time, however I eventually decided to use M60i trim.
