Had trouble at PA Turnpike with NJ EZ Pass Transponder not registering with I-pace. Had same issues on and off with 2017 F-pace. After reading F-pace manual page 97, lists exact location to mount transponder on windshield. Left Driver side or passanger side next to rearview mirror on dotted spot area is preferred. Any other location will have issues, because of heated windshield or solar attenuated glass. Or You can request licence plate mounted transponder if your state provides one. Lot of new generation cars have this issues due to HUD, heated windshield, cameras.
