I just took two trips on the Dulles Toll Road today using my EZ Pass Flex on the Mach-E. Thanks to this thread, I just checked my EZ Pass account and there are no transactions showing. I'll look again tomorrow, but will likely have to call them to see if they offer an external device.

@ChasingCoral did you use an EZ Pass on the Dulles Toll road?
I did coming out. I'm watching my MD EZ Pass bill to see what happens. I'll also take a spin on the ICC near me as a test once Marlin is out of the shop.

Don't exit the ez pass gate without paying in PA. They will read your plate and charge a flat fee of $10 to your ez pass account for every "offense". Using this racket, the PA Turnpike Authority racks up millions of dollars a year on fines and fees.

I learned the hard way. I had a broken transponder that I did not realize wasn't working until I noticed my credit card was replenishing my ez pass account too often...

so we don't think there is an area of the windshield that doesn't have the IRR coating? It seems like most manufacturers with these windshields do that...

Just ordered a license plate EZ Pass for Maryland. Hope that solves this issue.

I checked the manual. Nothing about a non-ir spot on the windshield. Might be one though. The WA site specifically says most cars with metallic windshields have a good spot and to contact the manufacturer...

from the texas toll

Why does the TollTag have to be mounted on the windshield?
The TollTag operates on a radio frequency and is best read from the windshield’s glass surface. Some vehicles have metallic windshields that can interfere with the electronic signal. In those cases, a customer may request a special TollTag to affix to their vehicle’s license plate.
Thank you Janitorjim I'll need one of those for my premium.

for the toll tag in Texas you can get an external transponder but only will work in Texas. To work in Oklahoma and Kansas need the windshield type toll tag.

If your car's license plate is added to your account, they will just bill you the regular toll without any extras. That's what we've been doing for a long time when we didn't have the transponder... the license plates are registered.

logged into the ezpass website and it's in one of the menus. $13.50
no such luck on the NY site - only type in the drop-down is "INTERIOR" :(

Ford Mustang Mach-E EZ-Pass transponder interference? 1613412617862


their site mentions plate tags in places. we'll just see what happens when I get my car. For the OH TP all lanes are tag enabled, even the manned ones - so I can try in one of those lanes. when I have a car.

Just looked at NJ as well. You need to request exterior tags through customer service. The page says they may request additional information. Given that Ford is silent on the issue, you may be stuck in limbo if they need Manufacturer info to prove you need it.

yeah for me the bigger problem will be that the account is grandfathered in from before Ohio had the system. I suspect if I call them it will force bad things to happen (my grandfathered account has no maintenance fee - Ohio charges one).

OK. I wouldn’t order the LPT until I tested my current transponder anyway. I haven’t looked in manual about this potential problem do you know if it’s mentioned?
I have read the manual cover to cover and I do not believe this is mentioned at all.
I checked the manual. Nothing about a non-ir spot on the windshield. Might be one though. The WA site specifically says most cars with metallic windshields have a good spot and to contact the manufacturer...
I searched the "Owners Manual" and the "Supplemental Owner's Guide" (both dated September 2020) for

  • toll
  • tag
  • transponder
  • infrared
  • irr

and got no hits.
