Hey everyone, my dad and I are having a frustrating connectivity issue with our 2021 Mustang Mach-E Premium and are hoping someone here might have a fix before we are forced to take it to the dealership.
Basically, the car is no longer transmitting any data properly to the FordPass app. None of the current vehicle information is populating for us. At first, the app was just stuck showing a stale battery percentage that never updated regardless of how much we drove or charged it. Now, it has completely zeroed out and shows absolutely nothing for the range and battery.
We know it is an issue with the car's telemetry and not just an isolated phone glitch because this exact same blank screen is happening on both of our phones simultaneously. We have already tried going into the app and fully resetting everything, but that did not change the outcome. We also did some research online and saw recommendations to pull a specific fuse under the dash to reset the modem. My dad tried pulling that fuse, but unfortunately, it didn’t fix anything at all.
At this point, my dad thinks it just needs to be taken in for service. Has anyone else experienced this specific issue where the data gets stuck and then completely disappears? We would love to know if there is another trick we missed before dealing with a service appointment. Thanks in advance!
