Is anyone else having this problem? I have tried three EZ passes. None will read when placed anywhere within the Tesla. A toll booth operator helped me out once by taking it out of the car and waving it around the outside of the front window. It worked! I took delivery in June. I've received over 15 toll violations in 7 states since then (I've been driving the car all over the U.S.!) I'd like to be able to go through a toll without opening my sun roof and waving the transponder around. Yes, another toll booth operator suggested that and it actually works. Anyone else having this problem? Given I've tried three transponders, it has to be my Tesla blocking the signal. Right?
