I opened the Ford app today checking to see if I was going to get an alert about the window wiper issue and got this one.

I got my letter for it today. It's for the Intake Air temperature sensor.

No parts available yet

Here we are in 2026 and Ford can't figure out IAT sensors, or how to have the ECU handle it not working.

Glad quality is job #1 at ford again.

If you're tuned, turn off auto update or be prepared to reflash your tune after this is applied. A PCM OTA will for sure overwrite your custom tune.

Is this a software, or a hardware issue?
It's a software issue.

With certain events, errors associated with the Inlet Air Temperature sensor will not be reported (see wrench light) to the Driver.

The fix will be a re-flashing of the Powertrain Control Module.

Contact your dealer for more information to schedule the free service.

I looked for a NHTSA report with detail, but that hasn't been posted yet.
