RF Hub Failure

[wheelz96]

I have experienced my first significant failure on my 2022 Ram Limited. Last Tuesday, when leaving work to go to my truck, I went to remote start and nothing happened. As I got closer I then just tried to unlock and nothing. I had to use the manual key to unlock and then the alarm starting blaring and truck would not start or any buttons would work inside. I held the fob to the start button an no bueno. I tested my battery and it was 12.9V and I had wife bring me my spare key and same thing.

I had to tow this thing to the dealership and have determined this is the RF hub failure. My truck is a 22' so not sure if the rear window leak is still an issue on my year but the day this happened was 70 degrees and sunny. I also felt back around rear window and back carpet for moisture but did not feel anything. This was brief as the alarm was blaring and I was waiting on a tow truck. Fast forward to today and the dealer finally started working on it and i got a video from mechanic stating both key fobs are fine and he will be replacing the RF hub.

I suspected this was issue from the moment symptoms began so no surprise here. However, when I called the dealer to inquire more about lead time, the service advisor stated they will also need to order a new BCM which is apparently on BO and he does not know when this will be in. I'm still waiting on a new radio from the dealer that was ordered back on 10/2025 and still nothing. My stomach is upside down thinking about this as they dont even have any loaners they can provide.

I'm sure my warranty will cover this but my question to the forum is, if the RF hub fails, does this usually take out the BCM with it? I still dont know if this is precautionary or standard when the RF hub fails?

No matter what, when this is all said and done, I think I will be moving away from Ram. Something this new and expensive should not be leaving me stranded. Not saying a GM or Ford wont do the same but between this, the radio, and the fact the truck only has 20,XXX miles and I'm having this much of an issue, I will take these signs and move on.

Unfortunately, all new vehicles are completely controlled by computers. One glitch and your vehicle can be rendered useless for a long period of time. This is some scary stuff. I have a 2022 as well, and am quite often on pins and needles just waiting for something bad to happen.

They can use a BCM out of a 2023/2024 model.

When the RF hub failed in my '21 (had to also have it towed after ticking off the neighbors with the alarm blaring 4x) they did not have to replace the BCM.

Do you know if the BCM is automatically prone to failure if the RF hub fails? I have seen many others have the RF Hub fail and replacement/reprogramming seemed to fix it. With that said, I spoke with a manager and told them to replace the RF hub, reprogram and if its still not resolved, you win and I will wait for a new BCM. They did agree to trying just the hub today and we will go from there.

Manager went out of his way to state its all covered under warranty which was never really a worry of mine, its the fact I have 2 kids in daycare and need my vehicle which they dont have any to offer.

I will post an update once the hub has been replaced in case anyone here experiences something similar.

They are not prone to failure.
