Safety Recall 22S27 Rear Axle Bolt Fractures

[KNTRDR]

I believe it's an effort to reduce the stress put on the bolt from "roll back" when the trans is in park and you're on a hill or uneven ground.

More to the point, it’s because if the bolt snaps, the axle can twist and the driveshaft can become separated from the axle, and then since the axle/wheels would have no connection to the transmission, the car could roll away while in park, potentially killing or crushing the living shit out of someone. The parking brake is a failsafe to make sure the wheels are locked.

Nailed it

The fact we're even talking about the need for a "failsafe" is somewhat concerning.

Yeah but if my wife was driving then it broke she would get pulled over put in it park and never set the parking brake to get out and look at what the issue could be. So I don't mind the programming. I wish the change had not been made in the first place on the diff.

Right on! Seeing they didn't actually fix the problem, the auto parking brake band aid is a must.

I wonder if we'll ever know why FORD changed it up.

In a way yes, but really cars have been equipped with failsafes for years. The parking brake, aka emergency brake, operated separately from the foot brakes being one of them - the car’s ability to go into a “limp home” mode if something fucks up and the computer can’t properly regulate the powertrain - the fact that if the ABS fails it reverts open to keep the brakes working the old fashioned way - the fact that if you put a mismatched size tire on, the car shuts off the 4WD to avoid chewing up the equipment.

In a metal box that can do 100mph, and really in any machine with so many moving parts and electronics and things that can go wrong, failsafes aren’t such a bad thing.

My comment wasn't adressing "falisafes" in general, it was about the need for a failsafe on a part of which the actual cause of the problem has not been addressed.

I can’t stand auto ebrake…yet another button I have to push every time I drive.

gimmie the real fix…wanna feel safe hammering the gas lol

curious If the recall is the reason my car has auto ebrake, or if that was already standard on 2022 ST’s.

You don’t have to press it! Just hit the gas and it will auto release.

 

[Doug]

yep, exactly what I do Not like. Jolting forward pressing the gas to overcome the ebrake. so it becomes yet another button to press every drive to make it a comfortable vehicle

That is quite the exaggeration or something is wrong with yours. When I manually set mine, I always release it with the gas pedal. A gentle tap and it releases easy. Sure, it’s not exactly the same as if you release it with the button but it’s definitely not anything I would be upset about.

It's barely noticeable on mine and I always set the ebrake. It's better for the transmission and this 10 speed needs to be treated gently as it's not very robust. I've had mine rebuilt at 25K miles.

 

[Doug]

was the auto ebrake a thing before the recall?

 

[Dale5403]

No, that's new.

 

[Doug]

No, that's new.

perfect, then I‘m aiming to get the physical fix (police fix) and guessing (hoping) it’s then safe to delete the auto ebrake mandate. utopia…axle won’t pop off and I can ease off the brake instead of hitting the gas when shifting into gear

 

[hbalek]

These people just don't get it. You don't have to accelerate. Literally a light tap of the gas releases it. Not even a blip on the tachometer. It's that sensitive. Same goes for the auto-start/stop using auto-hold. Tap the accelerator pedal and the engine restarts. I've used e-brakes with auto-release since my 2013 MKZ and it works flawlessly. No lurching or fighting the brake with the gas, It's electronic not mechanical. I'm so sick of hearing about this. And yes I have 2 bolts on my 2020 and haven't had the recall but I use my e-brake every time I park.

Actually, today I had an unusual experience with the Parking Brake. Preparing to back out of the garage, I put it into Reverse and tapped the gas, as always.

Nothing happened. Tired several more times. Eventually, it took a decent blip to the throttle to get it to release. It released with a jolt and loud noise.

Scary reversing out of a spot on grade with pedestrians potentially walking behind your car. Or inching forward in my garage with little room to spare. Always want the foot on the brake starting out in precarious situations. It’s truly a band aid. Can’t wait to delete.

Agreed. I’m so sick of repeating the same thing over and over. It’s quite simple and easy to figure out. People are over thinking this whole damn thing.
