Please, no one laugh, and I'm not saying this is a fix, try a KAM reset. I've gotten weird warnings and pop ups over the years, and luckily that solved the warnings.
These things have very strange electronics, to me at least. I hooked up lights to my console shifter gear positions, and lost my cruise. Did a KAM reset, and got it back. Not a clue in the world that what I did had anything to do with cruise. Just a thought.

Did you only replace the sensor wire? The exciter portion of the speed sensor is integrated into the bearing itself. 99% of the time it's the hub/bearing assembly that needs to be replaced.
I've got a 2017 with the 2.7, 3.55, and about 45,000 miles
Long story short, hopefully won't still be long.
Drive about 11hrs this weekend, and around hour 7 I got a bunch of notifications in the cluster: Service AdvanceTrac, Hill Start Assist Service Required, steering assist service required. I lost my cruise control, and my rear parking sensors as well
When I got home, I plugged FORScan up and it said I had a bad front left ABS sensor. I replaced that today and am still having the same errors and code via FORScan. The one I removed was insanely dirty. I sprayed some WD-40 around in and around the sensor opening.
I've done some research on these faults and many claim the fix is to replace the throttle body. This doesn't make sense to me since FORScan is literally telling me it's the same ABS sensor, but hopefully somebody can help me out.
Any ideas? My dealer in town SUCKS so I'm avoiding taking it in, and I'm also pretty mechanically sound.
Thanks in advance.

You're saying I may need to replace the portion of the hub assembly that the sensor is mounted to?
EDIT: I ordered the hub/bearing assembly. Comes in on Saturday. I had previously ordered a throttle body, but haven't heard from the seller on eBay.
To be continued..

I just replaced the sensor, it's complete with the wiring.

Remove the four screws and thoroughly wash down the throttle body and the manifold opening. Give time for the cleaner to evaporate as it could be the cause of more codes on restart.

Are you only seeing codes in FORScan, no dash warnings? Codes will remain set until x numbers of engine cycles unless you clear them while in FORScan.

Codes were cleared with FORScan after replacing the sensor, and the codes immediately came back once I started driving and got up to about 20mph or so

Definite possibility. Would a hub bearing wear down even without a bad IWE though? Seems like the best bet would be to replace them both and inspect the vacuum line(s)

Hub bearings wear down every time you drive. The IWE diaphragm is like vacuum hoses, it's aging constantly. IWE longevity, however, is most often a function of the vacuum system remaining in good working order.
