The 21P22 software update program is ending on November 30th 2022. I strongly recommend anyone with a 2021 Mach-E built before Sept 30th 2021 get these updates applied (if you haven't already) while they are free. They provide many improvements in software made since your vehicle was built (such as PAAK). After the program expires, it will be much harder to get your dealer to update these modules without charging you.
Original forum topic: Customer Satisfaction Program 21P22 - Software Calibration Update
Due to current dealer service backlogs, try to schedule with your dealer ASAP if you still want 21P22 done! You might have to wait a month to get in.
How do I check if I'm eligible for the 21P22 updates?
What if I don't see 21P22 listed?
Then it was either done already, or your vehicle is too new to qualify.
I've gotten some OTA updates, do I still need this?
YES! OTAs do not update nearly as many modules as 21P22 does. Most OTAs only update one module, 21P22 updates up to 13 modules. 21P22 also updates modules that have never had an OTA update yet, including the door modules, BCM, and RFA modules.
Will all these modules be updated by OTA eventually?
I wouldn't count on it at this point. Ford is assuming you'd come in for 10k services or recalls so would get these updates during the past year, meaning they wouldn't have to OTA them.
Will this improve PAAK?
YES! The latest RFA module update makes PAAK much more reliable. Significant improvements have been made in the software since your vehicle was built. PAAK is now reliable enough for daily use. I've been using PAAK daily for months, I never carry a fob and it hasn't been a problem.
Will this improve charging?
YES! AC charging speed is slightly improved. DC charging is faster above 80% (charge curve update). Compatibility with certain brands of DC chargers is improved. If you've ever encountered a DC charger that didn't work on the Mach-E but did for other cars, the latest OBCC update might fix that. Battery capacity will be increased to 70/91 kWh with the buffer adjustment.
Will this improve 12V battery issues?
It may. The latest version of the BCM software improves 12V management and some drain scenarios.
What modules are updated?
What if some of these modules have already been updated?
Not a problem! Modules that are already up to date will be skipped. In some cases there may be another update available since you last updated. Getting 21P22 done should ensure the listed modules are fully updated. You will not hurt anything getting subsequent updates on the same module.
Is this a recall?
No, it's a customer satisfaction program (CSP). You may get it done at the same time as other recalls however.
How long will this take?
The paid labor time is 1.3 hours. You should expect to drop your vehicle off for one day at the dealer. Rentals for 21P22 are not authorized unless you are getting other repairs done.
What if can't get it done before Nov 30th?
Try to schedule with a different dealer. After Nov 30th you will have to pay for updates out of your own pocket. Estimated cost $200-400.
Can I do this myself?
Yes, but it requires special equipment. See the DIY FDRS topic or contact a forum member near you that does updates.
What if I already got 21P22 done?
You only get to do it once. You may be able to get some updates through other CSPs or TSBs if you are experiencing issues.
