HV Battery Wont charge past 84%

[WoodduckMN]

Last week Ford came and installed software updates to my 22 Lariat ER. Now my truck won't charge past 84% on my L1 or L2 charger, but shows 100% 250 miles on screen and in the app, until I put the truck in gear then it drops to 84%.

I'm see a few others having similar issues in the last week.. also slow charging rates. I need to get it in to deal to test, sounds like a battery module failing.

Sounds like a bad module.

Unrelated to update. Sorry, but you likely have a bad module (SSM). Exact same symptoms as mine and a few others. If you have CarScanner you can confirm. Make sure dealer knows about the SSM.

Read this post, the symptoms you describe pop around message 17:
