Odd Electronic Behavior (Proximity Sensors and Door Locks)

[DNBush]

2020 Edge Titanium.

 

Two weird things have begun to happen.

• Intermittently the ability to lock and unlock the doors via the touch points on each door handle will stop working save for the driver door.  
• The proximity sensors will alert when there's nothing even close to the car.  This, interestingly, happens mostly in the morning when the car is first driven and then it happens only at the first or second stop.  

 

Has anyone else experienced this and if so, has a fix been found?

 

Thanks!

Someone else posted this recently, so I went and checked mine, and a couple of times I have had the same issue, only drivers door proximity works (I can only lock/unlock using the drivers door touch points). I went through the settings, thinking that it was related to the "Switch Inhibit" but I think that is only interior buttons. I went to the settings, and then tried, and all doors worked. It has happened a couple of times, because I more commonly unlock from the drivers rear door because I put stuff in there before getting in the drivers door.

 

What alerts do you get from the proximity sensors? What does this mean? The Perimeter alarm is door sensors (a door, lift gate, hood) opened without the vehicle being unlocked. I don't think any Edge gets a sensor alarm (movement, glass breaking) like the MKX/Nautilus.

What I'm talking about is the vehicle perimeter proximity sensors, the ones that alert you if you're too close to an object.  On the center screen they'll light up red briefly even when nothing is near me.

This is due to load shedding. If the battery is weak, the vehicle will slowly disable features to save power. The keyless entry touch points, except for the driver's door, may get disabled to save power.

One of the parking sensors could be dirty or faulty. Do you have the side sensing system? Sometimes the side parking sensors may get close to objects and beep.

Interesting on the battery issue.  I'll try to pay attention but I do believe that the issue with the keyless entry touch pads/points seems to happen mostly in the morning when first starting the car (remote start).  Though I know it has happened during the day after parking the car and then returning to it shortly thereafter.   

So does this imply my battery is losing its ability to hold a charge?

 

Regarding the parking sensors, yes the car has side and front/rear sensors.  Car is clean so maybe faulty.

When you mention that they will light up red on screen, is it always the same sensor?

 

Possible causes: Could there be any object nearby, such as a stop sign pole or plant? Could the sensor be pushed in or not mounted correctly? Is the road surface uneven that could cause the parking sensors to point down at the road?

 

The side parking sensors can be sensitive to anything nearby.

It's the front and sides (both) but mostly the sides and they light up red along most of the length of the image of the car.  It happens, mostly, when I'm at the first stop sign leaving my development.  Nothing within at least 25 feet of the car, smooth pavement.

It seems like the side sensors are just detecting the stop sign pole then.

Hmm... well, there's only one pole and it's happening on both sides of the vehicle.  Either way it seems somethings gone wrong.  This only started a few months ago.

You don't think it might be connected to the battery issue do you?

Well, I just had the battery checked.  It's fine.  I may have to go to Ford and see if they can diagnose this (and the sensor issue).

Any problems with active park assist?

Active park assist?  Is that the push the button and it'll park the car (parallel or into a slot) by itself?

If so, yeah, the problem is I don't trust it.  I tried the parallel one and it whipped the car into the spot so fast that if someone had stepped off the curb at that very moment they would have been killed.  Nope, not for me.

Yes. Active park assist uses the front side sensors to detect the parking spot. The system only controls the steering. It is the driver’s responsibility to control the speed of the vehicle by using the gas and brake.

Well, when I activated the active park assist for a parallel park, it told me, essentially, hands off the wheel and feet off the pedals.  It did it all and damn fast.  But accurately.

[Wubster100]

Yes, you remove your hands from the steering wheel. However, the vehicle cannot brake for you or control the speed. The driver must use the brake and gas to maintain speed and stop the vehicle when it gets close to obstacles.

Well, that would certainly be my preference but as I said, the car did everything.

@DNBush: From the 2020 Edge Workshop Manual, with emphasis added...

 

Active Park Assist

The active park assist system is a supplementary parking system that assists the operator with the task of parking in three ways:

• Parallel Park Assist - Detects an available parking space and automatically steers the vehicle into the space while the operator controls the accelerator, gearshift and brakes.
• Perpendicular Park Assist - Detects an available parking space and automatically steers the vehicle into the space while the operator controls the accelerator, gearshift and brakes.
• Park Out Assist (only for exiting parallel spots) - Analyzes the parking space currently occupied by the vehicle and automatically steers the vehicle out of the space while the operator controls the accelerator, gearshift and brakes.

Good luck!

Well, I can't explain it but, I have only attempted the Parallel and for the third time now, I'll say it, the car did all the work.

It is impossible for active park assist on the Ford Edge to control the vehicle's speed. The operator must control the accelerator, gearshift and brakes. The vehicle will control the steering. However, vehicles equipped with Active Park Assist 2.0, such as the 2024+ Lincoln Nautilus, will prompt you to shift into neutral. Then, you must hold down the park button. Active Park Assist 2.0 is not available on the Ford Edge. The driver must use the accelerator and brake to control the vehicle's speed.

I'm not going to argue with you.  I and the two other people that were in the car with me know what happened.
