Intermittent Tire Pressure Fault

[John S]

I have a 2021 Ford Edge ST, and when going on a road trip will get a sensor failure fault about every 30 minutes. It usually resets withing 30 minutes from the time of the fault. I have taken it to the dealer the last three oil changes, and they perform the diagnostic test, but because they cannot replicate the failure they have not been able to fix the problem. Failure to replicate the problem I believe may also prevent them from just replacing the sensor, the concern being Ford will not compensate them.  The car is still in warranty with 30,000 miles. The problem occurs only after driving for about an hour at highway speeds. It is the same wheel which move from front left, to rear left because of tire rotation. Has anyone else experienced this problem, or has any suggestions?

Take a photo of the fault indication and show it to the service manager - the service manager can report it as a failure without mentioning that its intermittent - if its the dealership where you bought it they'll be more inclined to help get it passed by Corp.
