Saber Amine

My car came with a dealer branded Euro (thin) license plate on the front of the car 20" x 4". To make a long story short my front radar was going crazy every time I pulled out of my garage or I was behind another vehicle. After taking it back to the dealer, the service department informed me that the licensed plate was the culpable party and it was blocking the front sensors. Sure enough once I removed it, the Pre-sense worked fine. I really liked the look of the longer plate and I was originally contemplating getting a Euro custom plate. Does the US get a different version of sensors? Does anyone have any information?
