The MME's first TSB! New software to fix LVB issues.
You're welcome. BTW, Marlin hasn't had any more 12v drain problems.The MME's first TSB! New software to fix LVB issues.

I'm amazed they're paying actual time!The MME's first TSB! New software to fix LVB issues.

The challenge is knowing IF it was fixed already. That may have been part of the delay for my car. It did not go to the KC Speedway, but did sit in MX for two months with the delivery date being pushed back a couple of times.It’s good to see a formal TSB for this issue. I wonder why the issue only affects some cars built before 2/3. If that’s the date they changed the software in the factory, you’d think all cars built before that date would be affected. Since it’s not a recall, I guess we’ll have to wait and see if our 12v batteries die to know if we‘re affected.
Probably a combination of all of the above. Software and Firmware updates (QA and dealer) on vehicles not delivered. Factory updates for those of us after that date (2/10 for me). And I'd bet part of this was also in OTA number 1 which just launched.The challenge is knowing IF it was fixed already. That may have been part of the delay for my car.

Given the timeframes on some states' lemon laws, Ford could get in a bind if any major issues arise requiring new modules....The good news in all of this is that the number of LVB draining incidents seems to be low and we know it's not a hardware issue given the contents of the TSB. With all the chip shortages, not needing to replace hardware might be a very good thing.
Use the Tracker at the top of this page.How do I check my cars build date? I didn't put a reservation I just bought it at the lot.
You can narrow it down to the month by looking at the sticker inside the drivers door jamb.How do I check my cars build date? I didn't put a reservation I just bought it at the lot.
It says that, but if you click on any of the tabs, like "General Information" it will show it.It didn't work. It just says Can't Retrieve This VIN
Not if it's already been delivered. It gets removed from the tracking database shortly after.It says that, but if you click on any of the tabs, like "General Information" it will show it.
