My service alerts are going crazy

[dakurz]

Can someone please help me and tell me what the heck is going on with my truck. And when this happens, it’s very difficult to drive. I step on the gas pedal and I have to go very deep down just to get the truck going. It doesn’t happen all the time but every once in a while this pops up

Lots of electrical gremlins on the earlier 21-22 F-150s. What year is yours? If it is in that range, you may want to consider replacing the 12V battery and under rear seat Aux battery. Lots of posts on this issue.

• Remember to do a BMS reset if you do replace them.
• If you have a PowerBoost, replace the main 12V with an H7 from AutoZone, Costco, Wal*Mart or something like that.
• If not a PB, you can replace with an H8.
• Make sure all fuses are properly seated. Half of mine were not.

Morning. Mine is the 2020 V8 Lariat. No PB. I changed the starter. The battery as well. Fuses look good. Have not addressed the aux bat.

Don't know that the 2020 has an Aux battery. This forum is for Gen14 starting in 2021. You might have better luck in going to a forum specifically covering your F-150 year.

Good Luck!
