FCW+ error. Need advice or suggestions

[scottmoyer]

Quick summary here. In May, I took my truck to the dealer to get an alignment after installing the Bilstein 5100s. While there, the dealer "good will" replaced my driver side axle because the CV boot was ripped. My 3 year warranty expired in December, so I was already out of warranty for 6 months at this point.

They aligned my truck 7 times for whatever reason. The wheel was off center, the truck pulled right, there was rubbing on the mudflap, etc. When I went to pick up my truck, the Forward Collision Light was on and I couldn't adjust anything. I mentioned it to a salesman because service was already closed, but he's no longer there.

The dealer told me that Stellantis is no longer honoring "good will" repairs, and some on this board have said differently, but I can't force the dealer to fix this issue under good will if they believe differently.

Reading multiple threads via Google search links associated with FCW+, I saw a couple things that have me questioning if the dealer caused this. I saw someone say they had the FCW warning after the dealer replaced the hub bearing assembly. No explanation as to why though. Another person said theirs was repaired when the dealer found an issue with one of the ABS sensors, since FCW deals with the braking system. Lastly, a third post mentioned that they had the issue after the LCA was replaced.

This weekend, I found my driver's side LCA bolt loose. I had a creaking front end since I did the lift, so I started looking for something loose and found the LCA bolt loose. I tightened it and the creaking is gone, but I never removed the LCA. Did the dealer remove the LCA to replace the axle? Did they potentially cause damage to the ABS sensor? Could it be something else near where they did the work? I drove the truck for a week after the lift without issues. The FCW light was on after they worked in it. They want to change me hundreds to diagnose and repair. I don't want to pay for something I don't use.

Advice? Suggestions? Is it possible they caused this?

i had a very very similar story with my 2023. A few weeks ago, I discovered grease slung around my driver side front wheel well area. After some investigation, I found my CV axel boot was torn. Not sure how this happened. Anyways, I too at the time, had the Bilstein 5100s as my leveling kit up front and have had them installed for about a year and a half prior to this. I took my truck to the dealer, they of course wanted to blame my leveling kit as being the cause of the CV axel boot being torn. But they did a good faith warranty for me since my truck only has 7k-ish miles on it. Fast forward, I ended up taking the Bilsteins out and installing the RC 3.5" kit. I did the work myself. Everything was fine on my drive home. Once I put my new wheels and tires on, I reprogrammed my speedometer with Alfa so it would be accurate. After that is when I then got the FCW error on the dash. I drove it a bit thinking maybe it would clear itself. It did not. I ended up just doing a soft reset by disconnecting the negative terminal on the battery for a few minutes and the error was then gone and has not returned since. I'd try a simple battery reset. Something may have happened the truck didn't like while it was being worked on and a simple reset may be all it needs. I also ran my OBD reader while my FCW light was on and there were no codes at all being thrown.

I've tried the battery reset and it didn't work. I've read on other forums that the FCW is a supplemental safety option and doesn't provide a code. So, without a diagnostic code, I question what the dealer will do for me.

You mention that you used Alfa to reprogram your truck. Do you know if Alfa can turn off the FCW lights on the dashboard? If so, I might just purchase it to remove the option from my truck. I don't need it

That I am not sure of.
