My Maverick doesn't have intelligent AWD, it's more like DUMB AWD.

At least it wasn't a post and ghost. Hope you get it resolved OP.

I asked Ai

And OP's follow-up is exactly why you shouldn't necessarily do that.

This is driving me nuts. My 22 Lariat AWD Ecoboost has a really strange AWD behavior that i haven't seen in my last AWD car. Basically it runs like a FWD until the front wheels spin, then it finally starts behaving like an AWD car. I can see this through the AWD monitor on the dashboard and also feel it when accelerating. But after maybe 10 minutes of proper AWD with 60-40, or 50-50 bias whenever i step on the gas, it just goes back to almost pure FWD mode. Shouldn't it kick in if i give it enough throttle from a standstill in order to prevent wheelspin?? It's like the computer is too dumb to predict when it's really needed. Instead it seems like i need to burn out my front tires a little if i want AWD functionality, and only just temporarily... I used to have an AWD RAV4 and it never failed to kick in, so at no point did i ever have any front wheelspin... It's definitely not related to fluid temperature because i've driven the shit out of it the last couple of days and it just LOVES pretending it is a FWD Maverick.

EDIT: I just talked to the Ford dealer and apparently they have not programmed the RDU they just installed on my Mav (the original one died at 28k) So that explains why it's acting so weird. I've got an appointment to get it programmed. Scary to think a non car person could have simply continued driving without noticing anything.

Crazy they would replace the RDU and completely skip the programming! That explains exactly why it was trapped in front-wheel-drive mode—the computer had absolutely no idea how to talk to the new clutches.

Slapping a fresh mechanical unit under a modern truck and forgetting to calibrate it is a classic dealership move, but it's incredibly sloppy. Running it completely unprogrammed is exactly how you burn a brand-new unit up all over again. Glad you finally got an answer, because that behavior would have driven me insane too.
