The ACC/FCW system on an early 2017 Pacifica Limited fails intermittantly on long trips with the message "ACC/FCW Unavailable Service Required". But when the car is turned off and then restarted the system resets. When I take it to the dealer no errors are active so they "can't get a code" so "there is nothing they can do". I've taken pictures of our dash showing the error and the little yellow error icons, but my car telling them that "Service Required" is not good enough to get any action. Why don't I bring it in when it occurs you might ask? Well I work 8:00 to 5:00. We take long trips at night and on weekends. When are dealerships open? Not at night and on weekends. I've emailed and called Chrysler Customer Care trying to get them to take this seriously as a safety issue but they just send messages or try to set up appointments with the same dealer who can't help! Aaagghhh!!!! I have stopped at Autozone and have them use their code reader but nothing shows up. Advice please?

Hey Gerry. Your thread was awaiting approval because your first post was a new thread. It's been approved. Hopefully someone can chime in with some helpful info. You can try to get a cheap OBD2 reader and plug it in to see what code it throws while the issue is happening to get an idea where the error is occuring. You can also try to get @ChryslerCares involved to see if they can assist you with the dealer. Not sure if you're in Canada but the Chrysler cares on this forum can only assist with US issues. Welcome to the forum and hope you get your issue sorted.

Inexpensive code readers can be had for less than $50 US. I am not sure, however, if the system will necessarily throw a code when your problem occurs, although a code reader is always a good thing to have available.

I might suggest cleaning the from radar sensor. The system should distinguish between a dirty and failed sensor, but maybe not. It's worth a look, and could be a pretty gosh darn cheap fix.

Our 2017 Pacifica Limited has been having the ACW/FCW unavailable service required message intermittently for the last 4-5 weeks. It helpfully suggests to wipe the front radar sensor, which I did several times and it made no difference. The error message is on 90% of the time but intermittently goes away and comes back when you hit a bump in the road so more than likely some sort of a loose connection or broken board or wiring harness somewhere in the sensor. I wasn't particularly concerned and thought I'd defer it to the next oil change in 4-6 weeks.

Here's where it got scary. Two days ago the wife was entering the expressway ramp with no car in sight, in front or rear, and accelerating when the words "BRAKE!" flashed on instrument panel (typically shows up when front collision warning system detects an imminent collision) and the van slammed on the brakes autonomously! She was lucky there was no one behind to rearend us. Needless to say she was shaken up and very uncomfortable in using the car until its fixed. I was able to get an appointment for Monday Feb 12 so I will report back what they find.

Other than this we have had minor easily forgivable issues for a new model year car. We still love this car over the 3 Honda Ody's we have owned in the past.

Should be reported to national highway traffic safety admin as a safety hazard as this vehicle has multiple electronic issues associated with the it.

You can turn off FCW emergency braking in the settings app, which we did now, so its no longer a safety issue.

Dealer looked at van today and found that the front radar sensor is misaligned and its seeing the ground which it thinks is a obstacle and I presume keeps deactivating itself as a sanity check. The reason why its misaligned however is because the bumper bracket is bent and more than likely someone backed into the van. It's a body shop/insurance claim and nothing that was the fault of Chrysler engineering! Other small issues being fixed while van is in shop today:

1. Rear trunk lid foot sensor inoperative
2. Driver side sliding door does not close 2 out of 5 times. Beeps and re-opens
3. Passenger side sliding door grinding noise
4. Safety recall ECM reprogramming
5. Transmission loud thunk (almost like somebody slammed into the car) when accelerating from near stop
6. Oil & Filter change

The one annoying thing about the Chrysler experience thus far however is that Chrysler warranty does not cover a rental car even for warranty covered work. Dealership will pay for a rental for the first 12 months as a courtesy, but not beyond that. We have 17 months and 26K miles on this van and we have to pay for a rental car even for work that is warranty related. For a near $50K car, it should be standard to cover rental for warranty work like most other manufacturers at this price range do. Of course you can call Chrysler customer care and see if they will reimburse but it seems that it should be standard. Just my $0.02!

I purchsed my 2018 Pacifica about 3 weeks ago. First drive to work I tried the adaptive cruise control. It’s started and then almost immediately the ACC/FCW not availble wipe front sensor message came up. Then I googled it and read this thread. I was thinking, “lucky me”. So I took it in to the dealer. They said they need to calibrate the sensor. I also have an issue with the bumper not snapped in all the way under the driver side headlight. You can see the unfinished portion of the rear part of the molding. We scheduled an appt for service so that I could get a loaner car. I dropped the Pacifica off at the dealership on 10/22 and picked it up yesterday (10/30). The bumper looks no different that it did before, but I wanted to get my car anyway so I jumped in and straight onto the highway to try the adaptive cruise control. We’ll it work for about 1 minute and the same message came up. This is very unfortunate, hopefully they can fix the next time. I notice my rear liftgate doesn’t have the reveal on each side either, but it doesn’t bother me as much as the front bumper and the ACC/FCW not working. I drive a lot, the reason I picked the Touring L was solely for the adaptive cruise. If anyone has advise on how get through the process of getting this sensor replaced or re-positioned quickly, please let me know.

Hi Spackage,
We're very sorry to hear that this was not resolved the first time you brought your vehicle to the dealer. Send us a private message if you decide to go back so we can assist you with having this addressed by your dealer.

I am new to posting in the forum, but am having issues with our 2018 Chrysler Pacifica Limited S. Tonight, it gave us the warning in the attached pic. At the same time, the window rolled down on its own. It has already been in once with a "Cruise/FCW Unavailable Service Required" message and the same warning lights that are in the attached image. When it was taken in at that time, the main battery was found to be faulty and was changed under warranty. After it was changed, it worked flawlessly for almost two months. We then received the message "Service Electronic Stability Control" with the same warning signs as the attached image and then we are back to tonight's messages. All of these issues and messages are cleared with turning the vehicle off and turning it back on, which doesn't inspire confidence. Has anyone else experienced this? Particularly with the window rolling down when these messages popped up? All help is appreciated.

While driving in the city today (an hour from home), I had the ACC/FCW error happen at 3 seperate stop lights. I also have had issues with my 2028 Pacifica not starting first thing in the morning. I left a message with my dealer, and am yet to receive a call back. I agree that this error should be reported to other agencies as well as this appears to be a badly designed 'safety' feature!

@CouldYouBeMorePacifica, I know this is an old thread, but I'm curious what was the fix? Our 2017 Limited started doing the same thing yesterday.

I scanned the Adaptive Cruise Control module and it returned these faults:
Error code: C2227 [ABS Disabled ECU]​
Error code: U0415 [Implausible Data Received from ABS]​
So I then scanned the ABS module and got these:
Error code: C2102 [Vehicle Speed Sensor Out of Self Test Range]​
Error code: C2100 [Battery Voltage Low]​

After the ignition is cycled the ACC/FCW malfunction indicators go away, but I get the light for the Stop/Start System being unavailable
Rectangle Font Asphalt Electric blue Symbol
.

My best guess is that it's something related to the battery/alternator/charging system (the Stop/Start System failure leads me this way) or maybe a bad ABS module? But the lack of an ABS error on the dash, makes me think this is less likely.

We are having the same issue with our 2017 we bought in May. We took it back to the dealer because they have a "LIFETIME WARRANTY" but they said it was the battery and charged us $530 for the battery and an oil change. On the way home it happened again. Very frustrated.

Sound like it's gotta be something within the charging system. Replacing your battery obviously didn't fix yours and I replaced the battery in ours about six months ago. The Stop/Start system stopped working and I was told it was because of a bad battery. So I replaced the battery and it seemed to fix the Stop/Start problem, I guess...but I'm starting to think it's all related. I'm outside of any warranty, so I really don't want to spend a bunch of money on something that only results in a temporary fix.
