Randomly UNAVAILABLE ACC / FCW?

I searched on FCW and didn't readily see if this problem has been reported before. 12K miles on my rig, and recently got it back from the dealer for fixing the cat and P20EE.

I randomly get the EVIC message:

ACC / FCW UNAVAILABLE
WIPE FRONT RADAR SENSOR

So yeah I've cleaned it, again and again. I still get the message. Any ideas as to the cause, and to the fix?

What's also happening is, I occasionally get the bright red BRAKE! and loud beeping when nothing is there. Annoying, and alarming, no pun intended.

Well, maybe Casper the Ghost was out there on the road...

Thanks folks!

Roy

Re: Randomly UNAVAILABLE ACC / FCW?

I have noticed I get the big red triangle when I drive over one of those steal plates used to cover holes in the road temporarily. I will get the FCW unavailable when it snows and I'm driving on the freeway but it usually goes away after a few minutes.

Re: Randomly UNAVAILABLE ACC / FCW?

I've had this happen several times on long trips and it always clears itself within five minutes. The dealer checked everything out, but couldn't find any problems - the sensor is tight and seems to be adjusted properly. On my trip to Oregon and back, it seemed to occur about every 250 miles, almost acting like something was overheating and resetting when it cooled down. The regular cruise works when this happens, so I just switch to it for a few minutes and then reengage the ACC. It is irritating though.

Same problem on a 2015 with 5500k miles. The first time they said they couldn't duplicate so I have started taking pictures everytime it happens. I have enough now and am taking it in soon. My dealer is not very customer oriented. On the Ford forums Ford representatives actually monitor the forums and jump in to help resolve issues.

I have crooked steering wheel, rough shifts and this issue with the adaptive cruise. Very frustrating and I am super patient with the dealer.

I'm lucky. The ACC and FCW are the only problems I've had (every now and then the FCW will go off unexpectedly, but I've determined it seems to be while approaching an overpass that is at the top of a hill. I think the radar picks up the overpass since the front end is pointing upward.) I'm also lucky in that my dealer is responsive and seems to take interest in the problem.

Re: Randomly UNAVAILABLE ACC / FCW?

Could also be happening if you drove through high snow or if smth/someone bumped into the front sensor. I had that happening last year...initially I thought it's dirty but no matter how much I cleaned it the error was coming back after 20 min of driving or so.
I did drove through high snow and carelessly bumped every possible snowbank when parking around
Sensor sits on a metal plate or smth and if pushed or pressed too hard need to be recalibrated. Took 5 min in my case.

Re: Randomly UNAVAILABLE ACC / FCW?

I constantly received 'ACC/FCW limited functionality' and last week, my camera module behind the windshield was replaced. Since then, it's working again. Prior to that ACC was actually working but I didn't get the 'BRAKE!'-warning messages anymore.

Tomorrow, I have an appointment regarding the crooked steering. Hopefully, this will be all for the near future..

Update - my message was different ACC / FCW UNAVAILABLE
WIPE FRONT RADAR SENSOR and the dealer stated the sensor bracket was slightly bent and they relaigned the sensor. Unfortunately, I don't have it back because they are having issues with the transmission and they put me in a rental car. I hope they get the steering wheel straight too!

This is the more common error-message in regards to ACC/FCW-issues.

Re: Randomly UNAVAILABLE ACC / FCW?

Jumping back in to report that the FCW / ACC was fixed and I've tested it on a few road trips. Am SO glad to have ACC working again! I was in slow-and-go Bay Area rush hour traffic and I loved its ability to track the car in front, just creeping along. It's great to have it back again, I really missed it.

Re: Randomly UNAVAILABLE ACC / FCW?

Hey Echo,

What was done to fix the problem? I am having the exact same problem and my dealer claims they can find nothing wrong. Also, now the auto dimming high beams no longer work. I wonder if both issues are related to the windshield camera?
