Reduced Powertrain / Reduced Power Notice?

[jthiesse13]

I got in my truck this morning after having it parked all weekend plugged in to find this message. I'm gonna call Ford and "hope" they have someone who knows anything about the Lightning but I figured I'd check here first to see if anyone else has gotten this message and what it might be. I have a '23 ER Lariat, interestingly, this popped up right at the 38,000 mile mark. Could be coincidence?

Dealer time.

I have an appointment at the dealer today. I'll keep everyone posted with updates. Hopefully it's nothing too serious.

My guess, based on your location, is that this is the motorized assembly in the shifter failing.

You might notice that the shifter is attempting to automatically return to park even though it’s already in park.

For me whenever I get this error, there’s a slight, repetitive mechanical/gear movement of the shifter as if it can’t determine that it’s in Park and is still trying to shift farther up. These errors started when I was in Los Angeles and went away when I go to a cooler location. And then earlier this week I was in Phoenix and it immediately started throwing these errors. I just replaced the shifter with a rotary dial about 20 minutes ago. I’ll be heading to Phoenix this evening and expect not to see this error again.

After you’ve had the dealer fail to fix it multiple times by replacing the shifter with the same part, there’s a thread on here in which people have discussed how to replace the shifter with a rotary dial.
