TSB 25-2048: Sync 4/4A General System Performance, Stability, and Intermittent System Reboot, etc.

[Firn]

I tried to get the dealer to update knowing I would need to pay the diagnostic fee. But I said no after they told me it would take 5 days to diagnose smh...... I mean, Im telling you CarPlay is hit or miss with sound, I am telling you there is a TSB out.......Why 5 days to diagnose? WTF......

Call the BEV team or have @Ford Motor Company help. There should be no diagnostic fee for a TSB designed to specifically address a customers complaints.

I requested to have TSB 25-2048 done. I was advised that it had been superseded by TSB 25-2105. The paperwork showed that they only updated the BCM. However, it appears that in addition to updating the BCM there were several additional modules updated (ABS, BECM, PCM, SOBDM, SOBDMB, and SOBDMC).

Unfortunately, since XLT 311A doesn't have passive entry or PAAK walkaway lock was not enabled.

I think a lot of people have the silent carplay issue. But I thought I was the only one on the speakers except mine is the rear will stop working. Bout as frequently as you say. Half the time though it happens I probably don't even know because I'm the only one in the vehicle.

Initially, after this TSB I had zero occurrences of this issue for a blissful 2-3 weeks. Now sadly the issue is back and is right around 1 out of 5 starts.

Does iOS 18.4.1 fix this for you? Supposedly this update, which dropped earlier this week fixes this issue.

I’m actually on 18.5 beta. We’ll see.

So I've had the TSB done at the dealer to address the carplay freezing and losing connection and the 18.4.1 update from Apple to address the issue and carplay turned off and restarted or turned off without restarting about a dozen times yesterday in about 3 hours of driving. No issues in my other two cars.
