GPS Strange Behavior

Recommended Posts

I have a 2017 MKX with Sync 3 and Navigation. Last week I was traveling south on I-35 from Iowa to Kansas City, MO/Overland Park, KS area using the gps navigation. About 75 mi north of KC, I noticed an icon on the gps screen. It was the letters "GPS" with a cross hatched circle imposed over them. Yet, I was following the gps track. I pulled off at an exit and noticed that the gps did not update or calculate a correcting route. However, the vehicle arrow was following where I was. I attempted to select "Home" from the screen and Sync took about 15 seconds to respond. Then, I noticed the time between selection and response starting taking even longer. I turned off the vehicle, waited a few minutes, and restarted it. Sync 3 response was still terrible and Navigation was frozen. I attempted to call the Lincoln concierge service but got a auto message telling me to try again or leave a message. I left a message for them to call me. I managed to cancel the current Nav destination and then attempted to re-enter it. The system failed to respond, and all the while, the GPS with the cross hatch circle was still displayed. I was thinking at the time that for some reason, the gps had failed/malfunctioned? So, I went to Android Auto, put my destination in my phone, plugged in the phone and restarted the car. Bottomline, I used Android Auto and google maps to continue the drive. When I got to my destination, I received a call from Lincoln. I explained what happened and was asked to check the operation at that point (about 2 hrs after the incident). When I started the car, all seemed well but the rep insisted in transferring the call to their Sync 3 specialist. When I reconnected, the Sync rep suggested (more like insisted) that I do a soft reset that I was unfamiliar with. Basically, sitting in the car with the doors closed, you put the car in accessory mode, turn it off, open the driver's door, with the door open - hit the door lock button and close it, wait 2 minutes and do a normal startup. There was no change, which I didn't expect because all seemed well. I asked if they had any history of this phenomena before and got the expected answer, "no, I'm not aware of any issue." The next morning, I drove to a local gas station using the finder capability. After I filled the car, I selected my home from the Nav menu and noticed immediately a general unresponsiveness from Sync. I'm thinking, "oh $h!T, here we go again. I pulled away to a safe spot away from the pumps and went through the "reset" procedure provided to me the day before. Everything including Sync 3 and Nav seemed to be operating normally. I selected home (Denver area) and was on my way. That night, I stayed in western Kansas, got up the next morning, didn't experience any issues and finished the drive home without incident. Nor has the problem reappeared since returning home. My Sync 3 software/firmware is at 2.3, the latest version. 

 

Sorry for the long posting. Has anyone else experienced or heard of anything like this? I know if I contact my dealer, I'm going to get the "next time it happens, come directly here" answer.

Don't have an answer, certainly sounds like APIM failing. I do know that if the system loses GPS, the nav system will continue to attempt to maintain your location based on vehicle speed and direction. Corrects when it gets GPS signal again.

 

If it were me, I'd run it through the dealer and see what codes are stored. Get a history built up as APIM replacement's are over $1000 (with nav).

Ford issued a tech note on this problem:

 

SSM 45917 - 2016-2017 Ford/Lincoln - SYNC 3 – Inaccurate Global Positioning System (GPS) Tracking Or GPS Vehicle Icon Spinning Or Spinning Compass - Engineering Investigating

 

Some 2016-2017 vehicles equipped with SYNC 3 may experience the following concerns; the GPS not tracking the vehicle position correctly, the vehicle location arrow icon spinning in circles on the navigation screen or a spinning compass on non-navigation vehicles. Perform the following procedure to resolve. Enter BezelDiagnostics per Work Shop Manual (WSM) Section 415-00. Select Testing Settings from the menu. Scroll down and press Clear DR calib. Perform a drive test for approximately 10 minutes, include at least four right turns and four left turns with a vehicle speed of at least 25 MPH. Confirm that GPS position for Navigation or the Compass for non-navigation vehicles is functioning properly. Engineering is aware of this concern.

BTW, did you change tires recently? Know to cause this.

No recent tire changes, but received normal service the week before that included a tire rotation.

Where did you find the TSB?

Ford tech on 150 forum states going up in tire size is a known cause to this problem.

 

Others in the forum who have had this promlem have had APIM reloaded at dealer. If it continues and gets worse (taking longer to lock in), only a APIM replacement will fix. Recommend you consider maintaining a warranty (extended) just in case.

After reading your post, I called my dealer. The service consultant acknowledged that the issue is rather widespread. "When it does it again, and it most likely will, call us immediately so we can grab the code. We'll reprogram the APIM and when that doesn't correct it, replace the unit. It's a well known issue."

When I told him that the Lincoln concierge folks said they had never heard of the issue, he laughed.

Thanks.

Feb 1 - third instance where I had a GPS failure (little GPS with cross hatched red circle around it). Per instructions from last experience, I went to the nearest Ford dealer to get checked. Basically, I was told that they wouldn't be able to address it for a few days. What a bunch of BS! It's not like I could drop the car off 30 miles from home. Making matters worse, after going back to the running car, I turned it off for minute to get my bearings. When I restarted, the error has cleared. Is this going to be another one of those damn problems that has to be caught in the act before anyone will do anything about it? The original Sync is the reason I got rid of my 2013 Edge.... now, the BS continues.

Update, I opened a trouble issue with Lincoln Client Services. The problem continued to be elusive. Lincoln client services suggested when it happens that I immediately go to the nearest Ford or Lincoln dealer and they could capture any error codes. Well.... it did and I did drive straight to a dealer (not mine). They told me flat out that they were too busy and blew me off, so I turned up the gain and wrote a long email to my purchase/servicing dealer with copy to Lincoln Client Services that they were creating a Catch 22 scenario and I considered the dealership network and Lincoln itself as somewhat unresponsive. Next time it happened I captured more video and a ton of pictures. I was emailed by client services who were about the clear the issue. In as nice as I could muster, I pretty much demanded that the issue could not be closed until I saw some sort of real resolution. Shortly after, the dealer manager called and assured me they would be responsive and encouraged me to make another appointment with the service department. I did and as a result they ordered a replacement APIM. That was last March and until a few days ago, I have had no issues. Then Tuesday, the familiar GPS letters with the red cross hatched avatar showed up again. Took another picture and immediately called the dealer. We decided to watch it until my next oil change in a little less than 500 mi.

TO BE CONTINUED?

So, it's been 9 months since my last entry where I had the elusive GPS issue again. That time I had a the GPS in a red-crossed circle but navigation didn't seem to be in error. Figure that one out. The dealership installed a Sync update and I haven't seen the issue since. I still have 9000 mi left on my warranty so I'm actually not too concerned right now.
