Help! 2022 Mustang Gt 401A Screen Not Working

[22Coyoti]

Hi,

I’m experiencing an issue with my 401A Digital Dash and wanted to see if anyone else has encountered the same problem. The screen doesn’t fully turn on—it just lights up. It is strange because it will resolve itself, but then the issue returns. The dealer did a update and it didn’t resolve the issue.

I’ve attached a video for reference.

Thank you.

No bueno man! Hope you get resolution.

I'm guessing loose cable somewhere as it bounces around it comes on and goes back out .

Or could be a heat problem and it eventually gets so hot it stops working for a while.

Either way I'm betting Ford's suggested repair is to replace the digital dash unit completely

That the car is still under warranty is a good thing. And you've already started a paper trail.

Can you give more details as to how it fixes itself, then fails, again? Under what conditions (time, temps, etc.)?

Edit,

It's a different Model Year, different screen entirely, but the S650 has some cars under recall for a screen issue, their's never coming on. In those examples, it's something related to the chipset and the firmware. I'm not implying your issue is related to that. Just weird...that may be why your dealer first attempted to re-flash the Body Control Module, to re-baseline module firmware; it's also the simplest step towards resolution, before going into the dash.

Thank you for your response. It will go months without doing this. The other day in the garage I went to start the car and no screen. 5 minutes later screen back on.

My initial thought is, if the car is not throwing codes, if there are no other tells something is awry, remove and replace the screen while under warranty. As the screen is being replaced, any of the connectors, harness and whatnot can be checked to confirm they are secured and run correctly.

Edit,

I can appreciate the dealer wanting to replicate the problem before going further. Their first step, re-flashing the BCM, was fine. But if the failures continue, even without consistent replication, the Service Advisor should be agreeable to replace the screen. If something obvious is found during disassembly, like a half-on/off connector, great. Once correctly secured, let's try that next. Otherwise, replace.

In the mean time, document anything you can. Dates, time, location, condition, etc. These facts can be input as part of the warranty claim and Oasis Report.
