I have my '21 RPM 2500 at the dealer for warranty service on the BS issue. I had spoken with Ram Customer Care and they had taken pains to tell me that the factory had found a way to reproduce the problem and that they knew the fix was to replace the trailer tow module. Well, today I talked to the dealer and they told me they had been in communication with Ram Customer Care and that despite receiving some information from them, they were not able to duplicate the problem.

My next move is to call the representative of Ram Customer Care that I had spoken with earlier, and try to light a fire under her. If the dealer can't reproduce the problem, they cannot fix it under warranty.

I had the module replaced ….still have the problem… I videoed the issue occurring when I applied the brakes.

i have a new 2021 Promaster based class b rv and have been experiencing the intermittent “blind spot monitoring disabled” notification. I can turn the system back on through the stereo but the issue resurfaces inevitably. Seems like braking MAY trigger it, but it not always the case

Additionally I get a “Foward Collision Warning System” disabled notification and dash dummy light sometimes.

Hope Ram figures this out.

we have the same problem but our Pioneer radio has also gone out twice. Jayco says Dodge needs to update the software with the original taxi and then reinstall the Pioneer. Dodge says it is a Jayco problem. Our dealer is trying to figure this out. We are not confident they will find a solution.

Our RV is a 2022, Jayco Swift 20T.

My 2021 Promaster RV has similar issue. 300 miles on it so far. Blind Spot detection turned itself off on drive home from dealership...it was off when I started the engine for the first time, and I turned it on, and it turned itself off on drive home.

For me, it seems related to whenever I hit bumps or potholes. It turns back on readily through the Uconnect interface.

I think the visual coverage, between the lower blind spot mirrors, the side mirrors, and the digital rearview mirror, is excellent, so I feel I can see my blind spots pretty well.

I think the consensus seems to be bad connection because of the trailer tow box (through which are connected the blind spot sensors). I wonder if I have a dodgy wire connection somewhere...which is why it turns itself off whenever I hit a bump...central processor loses connection with sensor temporarily and shuts off the system...then gets connection back.

I am planning to bring this up at next service interval, I think...

We too are having the Blind Spot Alert Disabled notice in our 2021 Dodge ProMaster. The Dodge dealer says they don't have a clue how to fix it. Because ours is a Jayco RV, they are saying it's a Jayco problem. Jayco says it's a Dodge issue. Given what I've read here, I am apt to believe it is a Dodge issue as it is occuring in ProMasters that are not converted to class B RVs. I would just like to get some help getting it fixed. This is a safety feature that is extremely important, especially with a large vehicle.

We are having the same problem with our Jayco RV, built on a Dodge Promaster chassis. Have you gotten a solution to the issue?

@jerickso , Please make a proper introductory post first. thanks

 

[Webster-DL]

I think until FCA releases a more formal solution, maybe I just do what the other poster mentioned: I just drive with the screen set to the settings page so I can turn the blind spot back on with a minimum of fuss.

Heck of a workaround...hopefully just temporary.

 

[Webster-DL]

Ok...update.

Since last post, ive taken the promaster out twice. I left the management screen on the "Blind Spot management" page while driving...where you can turn the Blind spot detection on/off/on with chime and lights.

A couple of days ago the blind spot turned itself off spontaneously and I turned it right back on again.

Well...since then, it hasnt turned itself off again...it used to be doing that like twice every drive.

I don't know if I can say it's "fixed", but it seems ok for now. Maybe the parts on this new promaster (like 320 miles) needed to "settle" together or something...dunno.

Just thought I'd let everyone know...

 

[Webster-DL]

Ok. So it appears I spoke too soon.

Went for a drive today. Blind Spot went out five times. Appears that each time I was trying to make a turn or take a curve in the road, and I touched the brakes.

I was able to turn it back on each time, but it did go out no less than 5 times.

Just an update.

So sorry to read about your continued concerns. Could you send us a message with your VIN so we can look into this further?

I took my van to another dealer for servicing today. I encountered another service manager who looked baffled and amazed when I told him about this problem. What a disconnect between forum members here and the people who are supposed to fix our Promasters under warranty! Anyway, the van is there now. They did call us to come get the van and disassemble the bed and unload the stuff stored in the back because they needed to take the 2 vertical black panels out of the rear corners of the van.

Sure hope they find a smoking gun this time! Wish me luck .. we're going back out on the road in 3 weeks fixed or not.

The diagnosis came back that the trailer tow module was defective. They also said they were able to reproduce the problem at will. They have ordered the TTM and we expect to have the fix in place in about a week. Of course, we've been here before. Here is the actual text from the mechanic (a Promaster specialist at an authorized dealer):

"Tech scanned vehicle and test drove it. Tech verified client concern and was able to duplicate it by sitting a stop and letting off the brake and quickly hitting it again. While monitoring the PAM the data would show trailer equipped then change to non-equipped status. Tech checked circuits X774 from the TTM to the PAM. Testing procedure dictates that if wires are good then unplug the trailer tow module. If problem doesn't reoccur then remove rear bumper, tail light cover and tail light to check the X774 circuit for power. Circuit passed test and is clean of water. Then reconnect both sides and retest in the same order. After completing test tech recommended replacing the TTM/Park Module. Part ordered 5 day away."

So there you have it. BTW "PAM" is Park Assist Module, in one of the passenger pillars. I don't fully understand the written message above, but it sounds like they have access to actual factory test procedures.

We've been hearing that the trailer tow module is responsible for this issue. However, somewhere above in this thread someone said theirs was replaced without fixing the problem. So I'm hopeful but not 100% confident.

More useful information. Thank you.

Interestingly, I was having the issue with the BSM shutting off intermittently while driving my 2021 Promaster since picking it up last March. I installed a trailer brake controller while doing my build out and finally went to actually pull a trailer with my van and the trailer brakes would not actuate. I double checked wiring, and using a trailer wiring tester determined that the signal to my trailer brake at the 7 pin connector wasn't working. I very scientifically jiggled the connector at the hitch and the trailer brakes started working and getting a proper signal from the controller. We went on a 3 week trip from Saskatchewan to Arizona and back and the BSM never shut off once and has worked flawlessly since.

Not sure what this means in the scope of this conversation but it is very interesting that since that time, the BSM has worked flawlessly.

I will add the my rear parking sensors have started to act up, so that every time I am reversing the alarm is going off steadily, but this may be attributed to dirty sensors after my last trip through large amounts of road salt that still need to be washed off of the van and bumper.

I’d like to add my 2 cents to this conversation. I have a 2021 high top, long wheelbase promaster purchased new. For the past year or so I’ve been building it into a RV so it was rarely driven.

From the start the blind spot alert was never stable. I reported it to my dealer but didn’t take it in cause I was building the RV.

This past week we took our first long trip. The odometer was reading just over a thousand miles. We added 1250 in our travels. On the freeway the B.P.A. system worked flawless and for that I was grateful.

The problem popped back up several times on the short trips around town when the engine wasn’t up to full temperature and the cabin was quite warm (the AC is a bit slow). Sometimes we could restart the system from the radio but other times the feature was disabled and dimmed. It would only reactivate once the key was turned off which is a challenge when traveling with traffic.

I’ve driven vans for my business my whole life so I speak from decades of experience. The Promaster is easy to drive but the blind spots are extreme. I refer to my van as the Stevie Wonder edition.

I’m taking it to my dealer, Mike Toler in Morehead City, NC on Tuesday. The Blind Spot Alert problem needs to be addressed by Ram soon. This is an accident waiting to happen. A small car or motorcycle is practically impossible to see and, considering how careless most people drive, they have no idea how much danger they are in when the ride adjacent to a long wheelbase promaster.

Aside from this one issue, the Promaster is a fantastic van. My company also uses the Promaster City, another great Ram product.

Thank you, jc

How or to whom does one address a suggested recall to? This problem is egregious enough that IMO Stellantis should bite the bullet and issue a full on recall.

 

[avanham]

Same here - RAM promaster 3500. Blind spot alert disabled message pops up intermittently. Dealer has no ideas, so hoping someone here comes up with a solution.

I think the solution is known - replace the trailer tow module. For some reason many aren't working. RAM won't fix it under warranty at present until/unless their own tech can reproduce the problem. Mine could (see above for details) so they have gone ahead and ordered the new trailer tow module and it will be replaced within a couple of days.

Something needs to be done! Im curious if anyone on here has a pm with bsd that dosen't have a problem with it intermittently turning off on them? Please speak up if you do, I'm sure we are all curious about it.
