<UPDATE 3/29>
This is now the 3rd HCU that has apparently failed. My original failed per this thread, Ramcares expedited a replacement, which arrived dead/broken per the dealer, and the dealer to dealer part they replaced it with has now failed 9 days after closing my original case.

<original 2/21>
I own a 2018 Power Wagon and while I was on the expressway my truck had a sudden deceleration and almost got us rear-ended.

I had the cruise engaged and it unexpectedly shut off and the whole dash lit up with ABS/BRAKE warnings and a Service Electronic Braking System was displayed on the dash. It kept dinging and spamming the cluster lights every 30 seconds.

I took it to the dealer and set up an appt (they can't even look at it for 4 days and sent me driving it home - hope it is safe to drive!). I am still under my extended factory warranty, but given everything I've read on these forums, I am now expecting to be told there is a parts issue and to expect months of waiting for a replacement HCU. This could kill someone and needs to be a recall!

My question - Aside from the constant dinging, is the vehicle currently safe to drive? Aside from the TCS and ABS not functioning, is the truck otherwise safe to drive? The failed HCU/ABS module will not completely render the brakes inoperable? It will just be like driving an older truck not equipped with ABS/TCS?

Has anyone recently had the work performed? How long was your parts wait?

Please file a complaint with NHTSA: Report a Safety Problem | NHTSA
Due to the many complaints this is being investigated, and any specific details could help in the investigation. https://static.nhtsa.gov/odi/inv/2022/INOA-PE22012-9925.PDF
If the truck throws code C0020-01, which most do with this problems, the TSB for the fix is at: S2005000004 RAM Technical Service Bulletin
As you know the parts are the big problem and over the last year both the ABS module and the HCU have been on back order a number of times. The part number for the HCU changed in the last year suggesting the part has been upgraded. Maybe someone else has some idea of the latest on parts availability.. You can also contact @ramcares as they can provide some help.

Hey,

Thank you so much for tagging us in this. We'd really love to look into this with you, @catalyst . We look forward to assisting you with this.

@ramcares - I have not heard anything else from you since I provided you my VIN and other info about a week ago. Can I please get an update? I took the truck in to the local dealer they diagnosed a faulty HCU and ordered the parts. I have not heard anything else. They reported a 2+ month wait for the parts.

Hey @catalyst ,

We appreciate your patience as we started your case! We've sent the case number to you via direct message.

Hey @ramcares what is going on with replacement parts? Why are they still so hard to get? Almost three years ago your TSB for the repair on this said the ABS module was "on restriction," S2005000004 RAM Technical Service Bulletin
And now the HCU is back ordered 2+ months when we recently were told it would be available the end of January. After three years I would have thought you would have solved the parts problem since so many people are experiencing the failure. What is the problem with parts? @ramcares we have all invested good money in your product and we deserve an honest answer. Last year I traveled from California to Wisconsin and back. If this had failed in Minnesota would I still be stuck there? A little less evasion and more honesty would help everyone involved.

Hey,

We appreciate being tagged in this. We'd be happy to take a look into this for you. Would you mind sending us a direct message with your VIN so we can get a part escalation case started for you?
