Intelligent Cruise Control error

[Marc S]

Unfortunately that's mostly true. Sometimes though it's just the inability of the service advisor to put the truth into layman's terms. The sales/finance departments on the other hand are almost universally full of ?. ??

Service Advisor “truth”: Sir we need to keep you car because it’s hooked up and we don’t want to disable it. Translation into laymen’s terms: “Your car is parked in our lot out back and we just didn’t get to it”. Now that is full of ??

Absolutely. Consider if you didn't have FordPass/SecuriAlert to let you know that your car hasn't moved. Would you be more satisfied with the lie or the truth? Either way your car's not done. How many truth telling calls that get you yelled at would you like to make in a day? Often due to circumstances you have little to no control over. I never envied the service advisor's job either. ?

OK, I surrender, but just for the record, I would handle the truth better than a lie, but maybe I'm the exception. And I guess Service Advisors are just pencil pushers and not up on the latest car tech which is kind of sad. Anyway, have a good evening, I think we have beaten this to death and I hijacked someone else's thread

@Marc S , @Murse-In-Airy - any updates from your dealers? I'm wary to take mine in if this looks to be a protracted issue that Ford engineering still needs to figure out.

Yes. I got my car back on the 5th day. They performed the TSB for Sync and nothing else.Would not bring me up to 1.7.1 or update any of the 6 modules that were in need. I have spoken to others here that stated unless you have a really nice dealer they won’t do any of these updates unless there is a recall or TSB because they don’t get paid for it.
Hopefully you have a nice dealer. I unfortunately do not

No. I have a case open with Ford. A very nice person who is calling me and saying my dealer should have contacted me. They have not. And I’m on vacation half a country away. So I’ll deal with it when I get back to Northern NY.

Got a call from my dealership today. Appointment Thursday morning to have the IPMA tested and if bad have a new one ordered.

Out of curiosity, did they address the navigation issue or is that controlled by the same IPMA module? I've noticed that even with CarPlay navigation my GPS can get wonky. I have a pet theory that maybe our ICC issues are due faulty connectivity / antenna.

Didn’t even think to mention the navigation thing. We never use it. So it didn’t cross my mind. But maybe I’ll mention it Thursday when I’m there.

Latest update to keep you in the loop. Took the car back to the dealer today. They had heard from Ford and wanted to test the circuit to the IPMA which they had updated per the TSB above. Per BIG FORD, if the IPMA was getting reliable power, then they are presuming the IPMA is bad and want to replace it. If the IPMA wasn’t getting power then they were to track down the faulty circuit. Well, IPMA power tested fine so now they are ordering a new IPMA and we’ll see how long that part takes. I truly doubt the IPMA is bad as lane centering works fine. The speed sings are read and come up on the instrument cluster. And what does the IPMA have to do with the navigation?
Here is where it gets super interesting. Three days ago, we finally got a successful OTA 1.7.1. The first few key cycles after that, the Speed sign recognition problem (and the Ford NAV app) was intermittent. Then we had one key cycle of lots of faults, from OPD to Rain sensing wipers. Now, for the last 48 hours it’s been gone entirely. Not a single problem.
My supposition is that her car tried to get OTA 1.7.1 and for some reason was interrupted leaving some corrupted software. This corrupted software caused the intelligent cruise and navigation failures. Now that she finally got a clean install, with a few key key cycles / reboots to let the installations happen, everything is on the up and up. For both 1.4 and 1.6 OTAs, she got the updates a couple weeks before me. This time, she got the errors a couple weeks before I got my update (with one key cycle of errors on my car as the update was installed). So it is a assumption that her errors started when I would have expected her update to occur. Now with a fresh update, all is good.
To me, this really points towards letting us, the end user, decide when updates should be installed. Then we would know if the installation finishes cleanly, or if problems arise directly after. Could have saved me multiple trips to the dealer and them replacing an IPMA that is probably just fine.

Are you still planning to go through with the IPMA replacement?

Thanks for the update. Weird fact pattern and a bit different from mine. 1.7.1 didn't fix my issues when it installed. I'm taking it in in 2 weeks to get it looked at by the dealer.

I have been having similar problems with navigation System not booting up, the intelligent cruise control error message popping up and Apple CarPlay not working properly. All of my modules have been updated and I have OTA 1.7.1. So I was advised to do a master reset of the car to the Ford default values. After the master reset NAV system now works great and Apple CarPlay as well. Further the intelligent cruise control error messages are no longer appearing And it is working again. Thanks to breeves002 for the suggestion

I have been having similar problems with navigation System not booting up, the intelligent cruise control error message popping up and Apple CarPlay not working properly. All of my modules have been updated and I have OTA 1.7.0. So I was advised to do a master reset of the car to the Ford default values. After the master reset NAV system now works great and Apple CarPlay as well. Further the intelligent cruise control error messages are no longer appearing And it is working again.

What's the procedure for doing a master reset?

What's the procedure for doing a master reset?

Open the vechicle drawer
go to settings
select general
scroll down to reset
select master reset

This returns the car to factory default settings. All updates remain in place. PAAK and Ford Pass will be disconnected and you will have to set those up again. All profiles will be deleted. All charging locations will be deleted. All radio presets will be deleted. Etc etc. For me it was worth it. I just hope it sticks and does not get confused again. Good Luck
