Hey folks!
My FCW forward collision warning sytem does not work. I road tested similar vehicles that do work.
I viewed video's done by FAC and one engineer vedio by Stellantis on how the FCW works and responds.
I performed two simulation crash tests on my truck it blew right through them. No verbal warning or braking response.
I hooked up my scanner and drove 100 miles on highway 15 where there is a lot of Simi's rolling tried to get the FCW to respond numerous times. If I dont brake my truck will drive right up a semi's tail pipe! During that 100 miles I received no error codes.
Factory Rep. states no codes vehicle works as designed. Now this IS A BIG LIE! They would not road test the FCW for safety reasons so they never got my FCW to respond. So how in the heck can they tell me it's working as designed. I researched Their safety technology group for weeks before I ordered my truck. I was convinced I wanted it on my truck. From day one my vehicle FCW did not work. I paid for this system and it should work as advertised.
I should have videoed all my research but I didn't so I have to start over and compile evidence to present it in court. I also sent numerous Letters to FAC and Stellantis with know response. If any body with the same problem wants to help me out. They can send me a signed affidavit explaining their concern and what they been through with FAC.

Hello. My FCW (forward collision warning system) has not worked since I bought my vehicle. Been to Dealers 5 times and FAC representative inspected it.
FAC will not allow dealer to road test the FCW for safety reasons. All I hear no scan errors the vehicle is working as designed. False statement.
I drove similar vehicle that the FCW did work. I viewed FAC videos explaining the FCW operation plus one with a factory engineer do a simulation showing how the FCW should respond.
So I know what a working FCW looks like.
I did two crash simulations my truck blew right through them. No verbal brake warning nor brake assist activated. Drove my vehcile 100 miles on highway 15 with a onboard scanner connected. I used big trucks ahead of me to try to make the system activate it did not respond on multiple scenarios. The scanner never picked up any fault codes . If you have the same problem and frustration that I had. Please document and post your FCW history on this forum. I would like to see how many


people are out their with the same problem. I will be taking legal action and your post would be greatly appreciated. Thanks

I will ask the obvious question since you didn't mention it. Is your FCW turned off in the uconnect settings?

I generally go to an eye specialist if my FWC system is malfunctioning.

Mine works. I've had the truck for 3 years now and it has probably signaled 3-5 times in the real world. I put this out there to say that it has been my experience that it does not alarm simply because you are close to something on the road like the parking sensors do. Most of the times that mine went off the car in front of me was braking and turning. If I don't adjust speed by touching the brakes or letting off the accelerator the alarm will go off. It seems to be sensitive to changes in front of you not inspiring a reaction from the driver of the Ram. It would be interesting to know for sure what the programming says.

Mine works, and really well. Had a ******* the other day, 2 lane road, coming right at me and at the last seconds crossed over into my lane to get to the shoulder to thier mailbox. They cut over so close it caused the system to go off.

That was fun

I just bought a 2022 Limited. I thought the same thing when I first got it. It never went off. My previous vehicle was a Nissan Armada, and the FCW on it would go off all the time. I double checked the settings in U-connect, etc. (I also tried to get it to go off several times, and it never did)
Well it definitely works. Has gone off a few times, mostly in traffic when someone ahead of me slams on their brakes. My best guess is that the RAM FCW system works fine, it is just tuned to only go off when it really needs too...

Mine works. I get several alerts every week due to distracted drivers here in Va. Check your Uconnect settings it’s probably turned off or set to not alert.

Well now you will have documented that it does not work , so if you crash you have evidence. Try climbing the corporate ladder to get it diagnosed . In the meantime pay attention !

I'm not sure what you're saying. If you're implying that he won't be at fault if he rear-ends someone you're sadly mistaken. FCW is there as a backup. A driver will not be relieved of responsibility if it stops working and they get into an accident. And having it doesn't mean you don't have to pay attention, or as much attention, as someone who doesn't have it. The amount of attention you pay to what's going on in front of you shouldn't depend on whether you have nanny devices like FCW.

I bought a 2022 Limited Diesel in September 22 and now 4 months in also could never get the system to work as designed. It is set to max distance with braking and tone alert. I also have the 28m package for Pedestrian Emergency Braking and like another post set up a test using trash cans and ran at them going about 25 and nothing happened, not a noise let along braking. Had the dealer double check its all set to maximum warning level. When a couple cars have cut me off at high speed so close you couldn't read their license plate, again no chirp no braking. First dealer in San Diego said I don't have the feature ( it's on the window sticker, the build codes also agree ) second dealer now has had it 10 days and says it will only work when I get to one foot away from crashing, as designed. Funny the Ram Videos don't say 1 ft, that would sure make for one terrible wreck at 70 MPH. The Stelantis Agent assigned to my case is going with the dealer saying one foot is plenty of time. I would not want to be a pedestrian given 1 ft of brake time or some idiot that just pulled out while going 80 the speed limit near out Utah place. Please all keep posting if any dealer has found a repair that corrects this. Other than this one issue the Diesel and rest of the features are great.

where RowdyEddie lives, there are so many switchback 2 lane roads, it is almost a horse riding trail.
There are so many cyclists riding on 2 of the nearby roads, i don't like driving on them.
What is worse, i follow or lead semi trucks carrying trees down Old Castle Rd
This image was taken on Old castle Rd.

One even hairier day, i had to lead a large boat over Old Castle Rd. & then had to travel about 7 miles north on Lilac Rd.

Hey Eddie, do you have any update? My 2023 RAM 1500 has the same behavior, the FCW doesn't work and the dealership said it is working.

Hi op, do you have any news on this?

My 2023 RAM 1500 Classic has a similar issue. THE FCW never worked, took a few times to dealership, they acknowledge it is not working but the computer says it is, no error codes.

One thing they mentioned is my truck didn't come with ACC (adaptative cruise control) and the radar that makes part of it, but for sure it came with the camera (also they replaced the camera to try to fix issue).

Researching online (stellantisnorthamerica.com blog) I found this piece of text:

Full-speed Forward Collision Warning-Plus: Uses radar and camera technology. This system operates with all the capabilities of Forward Collision Warning-Plus. In addition, if the driver does not respond to the alerts, the braking system may bring the vehicle to a full stop when the collision threat is detected at speeds less than 25 mph.

This says the FSFCW-plus works with both radar and camera. Mine doesn't have the radar so I suppose the FSFCW does not work because of that. My conclusion is my truck came without all parts required for the FSFCW work.

I'm looking for legal advice about how to handle this. Other pickups may be in the same situation and this could create a recall.

How are you determining that it doesn’t work?
In all the time I’ve had FCW, there’s only one type of circumstance that I can “safely” and repeatedly get it to activate.
If I’m following a car in city driving, and that car is going to make a right turn into a business on the side of the road, I don’t slow down at all (or I accelerate) because I know that car will be cleared before I reach it, the FCW will think I’m going to clip it’s rear end before it is completely out of the way, and it will activate. I’m an aggressive driver, so that’s why I only have FCW set to audible warning.

There is another instance where I had is go off, but won’t apply to you because I have adaptive cruise.
If I have adaptive cruise on, and I’m following a vehicle coming up to a stop light. There is a vehicle in front of the vehicle I’m following that is already at a complete stop. My truck slows down at the pace that the vehicle I’m following is slowing down for the stop light. That vehicle then changes lanes. Since ACC does not recognize stopped vehicles (the one that is already stopped at the light), once the vehicle in front of me changes lanes, ACC starts accelerating back up to speed causing FCW to think I’m going to run right into the vehicle that has been sitting at the stop light if it doesn’t think I’m going to take action.

Hi Jimmy,

My previous vehicle had FCW and I know how it operates. Since I got the truck, August 2023, I never got any audio, visual or active braking from FCW, even when the car in front of me slam the brakes and I had to stop a couple inches before its rear bumper.

Another time I put a carboard fridge box in the street and ran over it. Not touching the brakes, driving at 30 km/h, and the truck just hit the box without any alert.

I also tried all sensibility options for the FCW in the Uconnect. Nothing changed.

Then took the truck to the dealership, they tried to align the camera twice, compared to the other trucks they had with FCW, the other trucks they got the FCW to activate, but mine not. They replaced the front camera thinking the problem was there, but stills the same.

The only difference they said is all the other trucks with FCW came with front camera and the radar sensor installed in the grill. Mine did not come with the radar sensor.

There’s no radar sensor in the grill for forward collision warning on any ram truck. Camera and radar for FCW is all contained in the driver assist module on the windshield in front of the rear view mirror.

That's interesting. Not sure why the specialist at the dealership I told me my truck doesn't have this radar sensor and the other trucks they have had.

I can see there are two things in the driver assist module, behind the glass.
