Forward colision avoidance

[hoejef]

Hello all just purchased 2021 Laramie and wondering if you could fill me in on it. I have tried all 3 settings but it does not seem to be working. I mean nothing no warnings no braking. I did take it to the dealership and they checked for codes and found none.
Any replies much appreciated.

Usually only warns you if your about to collide with something. I think it uses closing speed and distance to determine when to function. I also believe it does not function below 10 mph. But I could be full of sh**, too.

There was someone else who had issue with it not working few weeks back.

You didn't really give any details though. I can tell you when I first got my truck, my grass was setting it off. Then I turned off all those dumb things.

I recall someone saying to put a cardboard box in your driveway and drive up like it's not there and see if your system kicks in. Probably the safest way to test it. Good luck.

The OP raises an interesting question, how do you test the collision avoidance system? Asking a dealer to look for codes is fruitless, you would have a panel indicator lamp if so. Then you have to consider the possibility that the designers of the system didn't put in a DTC hook that would signal trouble at every possible place which could cause a no-op.

How do you test it? Well, mine gets a regular workout simply driving around in SE Michigan. It seems too quick to trigger at times but it did save me once, it reacted faster than I did. I understand the system uses a camera located on the windshield opposite the rear view mirror.

The OP is in Flordia, from my many visits to the wonderful state, I've noticed dangerous driving parallels Michigan in and around the metro areas.

I felt it kick in on my 23 when I was closing on a car that was slowing to make a right turn in front of me. I was braking lightly but being on a 2- lane access road my intention was to swerve a little to the left to clear him if he was still moving slow. The RAM couldn’t foresee my plan so it applied the brakes for me.

Mine beeps and bongs at me all the time. Making a left turn from the outside lane with 2 lanes turning left- it always thinks I’m turning left in front of a car to the left of me and beeps loudly at me which never fails to startle.

I am having the same issue, 2021 RAM Laramie

Sorry my notifications were turned off, so 2x to the dealer and no codes but they did do a physical test and agreed its not working. I also took its to a windshield shop to test and celebrate the camera and it works as should. At this point I opened a case with Ram customer care and will see where that goes, I have a feeling not so far.

 

[hoejef]

schu have you done anything about it

 

[Schu2021]

Yes, I took it to the dealer and they said the had the camera calibrated and checked for codes but It still doesn't work. Not sure what to do at this point. I don't want to do anything that would develop a bad relationship between me and the dealer. I was a Service Director at a GM Dealership for 38 years, and when someone would complain to GM, well then it just came back around to the Dealership. Don't want to be that complainer.

if i leave the tail gate down and try to back up....surprise!...those brakes lock up. If i try to back up with a door open....surprise!...brakes lock up....if i approach the wall in the garage too close or fast...surprise!..brakes lock up.

The card board box test is the best way to check that out.

 

[Jproven]

how have you tested it to confirm it doesn’t work?

 

[hoejef]

Well, fast-forward collision is working (Lol) I just had the same experience as DanAr's post above, so it is working.
I had tried just about everything short of running into a tree. My wifes Telluride will brake for a duck fart so I guess my expectations were a little high.

Hi, this thing happened with me and posted all story here:

Could this creates a recall for all 2023+ RAM 1500 Classic with FCW?

Hi everyone, I would like to share my findings about why the Forward Collision Warning on my 2023 RAM 1500 Classic never worked. I took her 4 times to dealership, they acknowledge it is not working but the computer says it is, no error codes. To clarity, my pickup came with Full-speed Forward...

In short, the FSFCW+ does not see trees, cardboxes or people, it sees vehicles. To activate, your speed compared to the car in front of you should be high enough a certain value which I don't know, I know that because mine mostly activates when the vehicle in front of me is stopped in a red light or it is braking to turn right on a driveway, and I did not touch the brakes until it is very close, like 15 meters away.

If your speed compared to the vehicle in front is not too much, the FCW will not activate and you will rear the vehicle in front. My truck does not have the front parking sensors and the Adaptive Cruise Control, which I think can mitigate these situations. Your wife's Telluride has, so that's why it reacts to.
