Hi guys,
I tried using my valid EZ PASS transponder while driving through a highway toll and for some unknown reason, my EZ PASS box doesn't work. I keep it inside the car and place it onto the inner windshield as I approach the toll but the EZ PASS system keeps telling me, EZ PASS not read. Unpaid toll. I keep going through tolls without paying. Then several days later I receive a letter asking for payment plus a fine amount for this infraction. My car is a 2017 car. Can anyone shed some light on the problem. I call EZ PASS customer service to complain but they keep telling me that my account is in good standing and there is no problem from their end. What's going on ???
Thanks.

 

The 2017's have that heat reflecting windshield that has your problem well documented. It won't pass the reader waves either. Jaguar says try the upper windshield next to the mirror. If that does not work you are SOL. One of the reasons I am glad I have a 2016.

Yes - the windscreen can attenuate the EZPass signal. They make an alternative transponder that attaches to the front license plate so that it's already outside the car. Lots of the Germans (BMW / Mercs) have it. I hadn't seen it as an issue on the Jags before but should be solvable with the front plate transponder

 

And if your state doesn't require a front plate, then use one of these:

But with further thinking, the transponder will NOT be secure - since you can release this device with the simple pull of a pin... Check with the vendor - they are VERY helpful!

 

My boss had the same problem on his Land Rover. The license plate xponder fixed it.

 

Try positioning it to the right of the rear view mirror, - not sure if anything changed for the 17 model year but there should be a small area there that allows the signals to pass through the glass

 

+1. Try that first. Otherwise the plate transponder can be mounted to that bolt that the StoNSho uses (if you don't use a front plate).

 

Okay, well now all of this makes sense. It was driving me crazy every time I went through a toll. The issue is the front windshield, got it.
Thank you

 

Yep. Same technology has rendered my $500 radar detector useless. If it was optional I would've picked a different windshield.

 

im having the same issue with my windsheild. the ezpass transponder works 95% of the time, but the radar is giving me fears because it didnt pick up on 2 cops that i passed that had their radar guns out

 

If you have zero deductible glass you may want to consider the sledge hammer option and ask for a 2016 windshield. Just sayin'

 

Lol... : )

 

I just purchased a 16 R F Type in Florida. Are you saying an Escort Passport radar Will work or intermittently only?

 

You should be fine. I think the infrared reflective windshield is only standard as of 2017.

 

I hate the appearance of toll transponders stuck to the windshield. The F-Type is the third car I have attached my transponder to the moon roof glass instead. Works fine. 100% of the time.

In fact, on two cars, the transponder is mounted to the top side of the sliding sun screen, between it and the moonroof glass, so you can't see it from inside the car, and almost impossible to spot from outside. There is less clearance here on the F-Type, but I improvised and still got it done.

 

I painted the transponder black. Absolutely cannot see it.

 

So did I. Here is what mine look like:

 

Is it left or right of the rear view mirror?

 

Mine is not the EZ Pass, but a similar Norwegian toll road system, and it is mounted to the left of the rear view mirror.

It looks like an oem part of the car, but it was originally white before it was painted matte black.
