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.
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?
