I’m not seeing how the OEM amp would fix the issue. However, on OTA vehicles the TCU is heavily integrated with other vehicle systems, including the Gateway Module. Without knowing whether the TCU is passing a network test and what DTCs are setting, it’s hard to say what may be causing the issue.

Thanks! I'm guessing the TCU didn't pass the network test given the Ford chat rep doesn't see it pinging since September.

Took the truck to my local customs shop and the awesome guys there showed me that the previous owner actually ruined the OEM sound system too, putting 90's garbage with 5 channels instead, purely focusing on volume. They don't even want to touch it to put it back, but told me they had an ex employee working for my dealership and could work with them directly if I did upgrade the sound system with them ($$$). What a disaster for my dream truck :(

There was an issue where some TCU had the wrong country code in the asbuilt data. Without knowing your vin or the value it’s hard to tell if that’s the issue? Do you have Forscan?

Sorry to hear about the trouble you are having. Stories like this are the reason I would only buy a used truck if it's 100 percent stock. I know that nothing is ever guaranteed but I'll take my chances over a vehicle that has been tampered with.

I don't. Really my first Ford and just purchased it 45 days ago.

I wouldn't buy anything different either. Unfortunately, I just trusted Ford's program and didn't do my own due diligence. Lesson learned the hard way, I guess...

Latest: Schaumburg Ford will reimburse me for the OEM amp, fresh oil + filter, and gas tank after telling them I'd go to the Commerce Commission and Attorney General if I didn't hear back from them. Will work now with my local dealership on what to to next.

Thanks everyone for chiming in. Will update this thread whenever we get to the bottom of it.

I’m still connected to my 22 raptor that I sold over a month ago. Dealer marked it up 20k and it hasn’t been sold. Go figure.

So I had a professional sound installer replace the disastrous installation that came with the truck and he thought it could maybe address the TCU issue since he never had an issue before in any other installation he had done. That didn't fix it.

I now have also the pre-collision assist warning going off (and eventually break-checking people on the highway) randomly. Took it to Lebanon Ford instead and... guess what? They say they need to replace the TCU AGAIN and would need to remove my sound installation.

Called my sound installer and he said there is no need to touch the sound wiring apart from disconnecting less than a handful of cables if at all to access the TCU. My service advisor doesn't want to work with my sound installer.

WHAT IN THE WORLD AM I SUPPOSED TO DO? Why are people so square? I understand the liability question, but it would be incredibly helpful if the Ford mechanic would just get on the phone for 5 min with my sound installer and sort it out - maybe it is just unplugging 5 cables to reach the damn TCU. If they figure it has to be disassembled, peace, but at least try. @FordTechOne any thoughts?

If you really want to solve this, I'd put the sound system back to stock and go from there. That will keep the dealership from using your sound system as a argument to not fix your issue. You really just need to find a stock amp.

Realistically, Fordpass really is useless. I haven't opened it in over a year. You are spending a lot of time and money on something that does not add an equivalent amount of value.

I'd give up Fordpass immediately, but the new issue with the pre-collision assist I can't let go.

Not really, that’s entirely dealership relations. Maybe ask if the installer can accompany you to the dealer to show them how the TCU can be accessed without removing the insulation? It sounds like the dealer is just being obstinate at this point.
