    Whenever I cross the Sault Saint Marie bridge into or out of Canada several electronic features are disabled by the bridge when I drive over it (auto off/on, cruise control, emergency braking sensor, etc). The vehicle is a new 2022 Grand Cherokee Limited. This never happened in my 2018 GCL. Crossing the Mackinaw bridge which is far bigger is no issue. Has anyone else encountered electromagnetic interference when crossing a large metal bridge? It happens every time I cross. I stop after crossing and shut off the vehicle for a few minutes then everything works fine. This vehicle is toast in a strong EMP event.
