False/Ghost Front Parking Alerts

[G213]

Hey All-

Did a quick search and couldn't find any threads mentioning this. (Please feel free to point me to any)

While sitting in traffic, I've noticed occasional false alerts for the front parking aid. The alerts are extremely quick, a very quick loud beep or two and it's gone. Most of the time, the "Front Park Aid" popup on the MFC doesn't appear. However, the tone is clearly for the front parking aid.

Interestingly enough, this only happens behind other Ford vehicles. Overall, I've observed this false alert approx. 40 different times and each time, a Ford vehicle was in front of me, equipped with rear park sensors.

When crawling in traffic, my guess is the front sensors do engage, as the system may not be sure if you're attempting to park. So with the occasional ping that's sent, the rear sensors on the other Fords provide the perfect backboard for the pulse, which is enough to briefly sent my front sensors off.

Anyone else ever experience? Doesn't bother me, just curious

Bought a new 2015 Ford Expedition Limited 4x4 - never wrecked or damaged.

The vehicle has done the same thing you describe (but not always around Ford vehicles - sometimes no vehicles) since I bought it.

I returned to to the dealer and was told there were no codes, thus nothing to fix.

The problems continues - now with 45,*** miles on the vehicle.

Since new, the vehicle has also intermittently and randomly displayed “trailer wiring fault” and “no key detected” messages. I have never towed or opened the four or seven pin connector covers. The “no key detected” message appears after I enter the vehicle and start it. Ironically, it did it earlier tonight.

The dealer also stated there were no codes for both of the messages above, thus nothing to fix.

Poor quality.

Ah bummer, but interesting. Thanks for verifying I'm not crazy.

I haven't even tried to bring it up to the dealer, since I can't replicate it on demand. I thought about checking the connectors to the sensors, making sure they are sealed and no dirt or water worked it's way into the pins. Maybe someday when I'm bored enough.

its a ghost in the machine
mine does it every now and then. I once thought it was the sun reflecting off the car or truck in front of me. They are very very sensitive. if i get repeated ones, i usually wipe off the sensors with a damp tissue, it seems to help.
Might be crap from road or bug guts..?? there is so much liquids from other vehicles maybe this may be the cause.

as far as the no key detected....its not often, but it does happen and i look down and the key is there int the cubby under the radio, if i pick it up and give it a stare the alert goes away...have no idea why
really gives me a jolt if it does it at 75 mph, my brain thinks oh crap the car is going to shut off.

i never get any trailer not connected codes unless i unplug the trailer. i would try plugging in a trailer and then unplug and see if it clears the random electron.
common network its just ghosts of tron

wait till level 5 autonomy comes out.....lots of wires and lots of high speed data. trades predict nearly 250 lbs of added weight from the right wiring required to handle the data transfers and speed on a four door sedan

I sometimes get a warning "Vehicle approaching from *** side" when backing into my drive. No front parking sensors that I know of.

Mine trigger on motorcycles riding lines at certain low speeds

The front sensors on mine go off all the time. It's pretty aggravating. Usually I'll just turn it off.

This is most likely the sensors picking up a radar pulse from someone else's BLIS or parking aid system.

My BLIS activates on guard rails, tall grass on the should or median. Kinda spooky sometimes at night when you think you're all alone.

Other vehicles BLIS systems can activate my radar detector, which is annoying. Really annoying. I can drive for miles with no radar alerts, then someone will pass me. Then for the next 40 miles its a constant alarm.

G213--yes, nearly identical to yours....Front warning only w or w/o visual alert and ONLY with a Flex, Escape or Edge in front of me.

No big deal.....

Noticed mine went off twice this weekend in direct sunlight. I was thinking to clean the sensor and see if that happened again.

We have a 2015 Expedition that is experiencing the same front park assist. It has been to the dealership 2 times for this issue. 1 dealership said that the sensors were dirty. Took to a different one and the tech asked if this happened if I was behind another Ford. I said yes. He says that there is something in the rear lights or that general area that makes it do this. The dealership is not showing any codes so they don’t have anything to replace. It is just really annoying when you are sitting in traffic and it goes off.

I've noticed it with F150s as well.

Try cruising at highway speed in the rain with traffic. System gets truly annoying then. Passengers freak out as they do not like hearing the beeps at speed or seeing the display switch if the event is long enough. Seems to trigger more when there is a vehicle in front and the sensors get hit by spray / mist. Heavy downpours do it too.

A buddy has the same issue with his '17.

I tried to turn-off the front parking system, but it returns with each vehicle start. Anybody find the code to move the default state of the front parking system to 'Off'?



And toward comments about ghost alerts for the trailer system, I recently got a warning that my trailer's right directional light was out, immediately pulled over (was at a slow speed anyway), the trailer lights were fine, and I gave a tug on the 7-pin connector to make sure it was secure just-cause. Has not repeated. Figured that the warning triggered as I was in a sharp turn at the moment and the trailer might have tugged on the cord a bit.

Despite not liking a potential false positive warning, it is potentially impressive that the system is checking for the state of the trailer lighting even when the light are not 'On'. Of course, this presumes that truck is actually polling the lights and this was not just a pure random false positive . . .

In the last few months my 2017 has been displaying the 'No Key Detected' message more and more. Today it did so three times. It has done it randomly in the past. It is indeed always jarring. Especially when the key is sitting right in the center console... Going to replace the batteries since they are two years old now. Hoping that solves this latest rash of key alerts.
