I've been fighting this all month. 85 messages on the ford app in 2 weeks- nearly all the faults the car can show. Took 2 weeks to get an appt, took my 2020 ST in Tuesday- they found a extra wire harness up under the dash- this may have been an alarm (I think the dealer alarmed them during covid when nobody was working the lot). Took it out and it cleared....1 mile after leaving all the faults are back took it back 10 min after leaving. Yesterday they said it's a PO504 code- Brake sensor, replaced and they say they drove it 25 miles. Took it home, went to fill up the tank and the errors back, but fewer. Took it back this morning, and they decided it's the half-shaft speed sensor (which I had mentioned when dropping it off- after reading the forums when the issues started- but why believe me?). Hopefully they get it replaced today. I'm out $700, including a $220 diagnostic fee which apparently gets added whenever you bring a non-warranty issue in.
I bought this in April 2020, might have been the first guy with the Blue screen back-up camera problem- took 4 trips in 2020/21, then the recall came out later. Overall, I've enjoyed it....we replaced a Jag F-Pace with this: more power, better 4WD on ice/snow, better gas milage, more comfortable to drive, better suspension, more safety features, and Massaging seats! and for less $$. But it has had more recalls, warranty issues, and now this sensor- than the 2 Jaguars I had before this car.
