Mine did that once. Happened when I shifted into reverse too quickly. Turned off car and let it completely shut down. Everything was fine after and hasn’t come back

If it doesn't appear again after turning the car off, leaving for a period of time and turning on then don't go it dealer... it's a warning that happens. If it appears again the next time you drive the car then that's the time to see the dealer.

There’s a TSB for it

Mine did that for the 3rd time just yesterday. It took me 45 minutes to get the car to start into gear. I ended up driving it straight to the dealership it will probably be there for a few days

Where can I see the open TSB for it? I do not see it listed in the sticky thread.

Any news @Electric Goat? I guess I'm the second one in the shop from what I can tell. Here's my situation/experience so far:

Ordered my Premium, AWD, ER MME in June '21, Oct 11 build week (so the TSB posted here in theory isn't an issue), and delivered early Dec. I'd had the car for about 6 or 7 weeks and only 770 miles before this issue popped up for me. Started on a Monday morning when I first powered up car and when I shift back to Park from Reverse. Has happened every time ever since. The car has never shown any issues with drivability however so added another 200+ miles before a service appointment was available yesterday.

Dealership failed to provide any info yesterday but called me around noon today. So far, nothing obviously wrong has been observed but the fault persists. Apparently all module diagnostics report back no problems so not clear that Ford will authorize any module replacements. Service advisor suggested that a networking issue is a consideration so a wiring harness or gear shift module (possibly being the knob in the cockpit...advisor wasn't sure) replacement may still be a possibility. The dealership is working with the Ford hotline to determine next steps so I'm guessing I probably won't have any details until tomorrow. Fingers crossed.

Curious as to what others will learn when they bring in their MMEs in the next few days...

@RailBlazer Mine was built near the end of September '21. I"m in the exact same situation as you and I have been told the exact same thing. Currently waiting for multiple teams to figure it out.

So I'll be getting a new GSM. Sounds like 4-5 business days to get the part (which isn't horrible given the general supply chain circumstances). Hope it addresses it.

 

[Fold88]

I got this message today for the first time. Less than 500 miles on the vehicle. Taking it in on Tuesday. I love the vehicle, but obviously have concerns with service needed this soon.

Had the software loaded at my dealer yesterday and everything is fine now

What is a GSM?

 

[RailBlazer]

Gear shift module. I would hope the dealership would check the firmware version of the module to ensure that it's the latest but when I mentioned the TSB, they didn't seem terribly interested given my car was built after it was released. Makes one wonder if I got one sitting at the back of the warehouse shelf though.
