service AT, ABS, hill assist, steering, blah blah all lit up. Sometimes it goes away, sometimes not. Came after I notices a LR metallic clanging noise. So whats the typical culprits ? ABS ring ? Thanks.

I had the AdvanceTrack Service warning pop up on the last 2 laps of my last HPDE session on Oct 8th. It then said something about “Drive mode selection unavailable” and knocked me out of Track mode.

I figured I just over taxed the system and needed to let her cool off. She was fine all the way home, but it popped up again two days later while cruising at 45 mph in third gear 🤷

Haven’t seen it since, but I’m weary that it’ll come back…

metallic clanging noise.. lets focus on that. When precisely does it make that noise?

That sounds indicative of a hub going bad, which would also explain the service advancetrac errors.

The rear hubs fail more often than the fronts (like, a lot more often). The hubs will sometimes make a ping noise when accelerating and slowing usually at low speeds when they're going. I've replaced like 5 over the years.. the original HUBs ford was using failed more often than the current parts.

Behind the hub there's a washer of sorts (called the thrust washer) and they can get mangled up when the hubs start to go and that's right next to the wheel speed sensors. You need to replace that too. It doesn't come with the hub you need to get one separately.

If you can jack up the wheel, then grab it with a bear hug and try to see if it shifts when you tug and push on the sides. If you can get it to move at all, its failed and needs to be replaced immediately (they can be dangerous to drive when they have some wiggle).

Wheel hub or speed sensor. Being you have an audible noise I'd say wheel hub. Lift it and wiggle the wheels. Should be pretty obvious which one is the culprit. If I was a betting man I'd guess drivers rear.

Sorry OP if I high jacked your thread!

Did you observe any error codes after each incident? Anything at all?
I read for codes immediately after I let her cool down for 20 minutes:

The Active Grill code is expected since I removed them but zip-tied the motor to the front crash bar.

Not sure the MAF code has anything to do with the AdvanceTrac message 🤷

Same issue, different symptoms. No metallic sound or anything like that. Power steering was intermittent and, ultimately ended up going out. No power steering, ABS, trac control or driver modes available.

Went the simple route and jacked up back end to see if I could feel any slop/play in the wheels, nothing. Ordered some ABS speed sensors, $70 shipped to me. Replaced and cleared codes via nguage, symptoms remained.

@fmc_smt hooked up and ran diagnostics, determined to be the rack and pinion/steering gear as culprit. Ordered new one (3 different versions, run vin to determine which one for you as they are unique per the factory rim diameter) and hope to have swapped out and programmed in the next week.

A serious PITA as the advance track system relies on ABS and the input of the steering - if part gives a fault, the whole system is failed.
