Powertrain Malfunction/ Reduced Power

[Marc]

I got into my truck this evening and when I put it in reverse to back out of the garage it surged and the lost power and I got a gold wrench. It states that there is a powertrain/four wheel drive fault and to contact the dealer. Has anyone experienced this before? I have 23 Lariat ER.

Lots and lots of posts unfortunately. Including me.
This is the main one: https://www.f150lightningforum.com/forum/threads/powertrain-malfunction-reduced-power.12873/

But there are others. Scroll down to the similar threads section of your post and see them as well.

Shifter module.

Search the forums for your thread title and you'll see everyone who's had a problem.

Welcome to the club!

Very likely yours is also the shifter - I swapped mine out for a rotary dial 3 weeks and 3k miles ago and bada-bing no more errors!

Ouch. I'm guessing you were out of warranty? No issues for my 2023 yet (warranty for a few thousand miles still). I have the rotary shifter sitting on the shelf if/when it goes.

It started when I had 43k miles, and I swapped it out at 49k miles. I have Ford ESP for 4yr/150k miles but chose a $200 deductible and the cost of the custom base and used rotary shifter was $160. I didn't want to have another one of the same shifters installed as I've seen posts by others that they'd gotten a replacement and encountered the issue again, so I decided it was better to go with the rotary shifter which I hope will be more reliable.

Mine was a shifter. But if your issue is accompanied by actual power loss, it's not the shifter, it's probably a bad battery module.

It ended up clearing itself up overnight. When I tried it in the morning it was fine. I did shift it quickly into reverse which caused the initial issue.

There is a "pseudo" recall on the shifters (CSP? Customer Service Program or something like that). After a bit of negotiation I got my local dealer to swap it. Of course the parts are on back order! The "magic date" (I think) is a build date of 10/18/24. My truck's birthday is 10/10/24! After that they reportedly fixed the shifter issue.

Anyone understand why a shifter issue would cause the dreaded Powertrain Malfunction?
