Totally Bonehead Move

[GPSMan]

Perhaps it fully applied the brakes, and the parking brake came on when it actually came to a stop? That would make more sense from a programming standpoint. The "slightly grabby" nature of the transition from "no brakes" to "friction brakes" might explain the "sudden stop" lurch.

You make a good point.
With all of 2 experiences while not "looking" specifically at the phenomenon and it passed in a moment....

Entirely possible the brake applied harshly first. Good thinking.

Prob no damage to the Mav. There were not any grinding sounds. The new F-150 pure gasser is worse. Open your driver's door without seatbelt fastened and it went to park at 6 mph and there WAS grinding sounds. How's a tabacca chewin Texan gonna spit?

I don't plan to make a habit of this, but looks like you can't put it in drive; jump out, and let the truck go over a cliff.

Man, how am I supposed to fake my death of driving off a cliff if the truck stops when I jump out?

I would have gotten away with it if it wasn't for you kids and that meddling Ford!

Ditto, only I'm 66. Some of those old cars were almost impossible to steer without power steering. My grandfather's 60-something Oldsmobile 88 was a perfect example. My father's '68 Buick Special station wagon was another. Others would flat-out lock the steering column as soon as the key was turned to "off"... I cannot believe a driver's ed program taught that it was a "good idea" to turn off the ignition on a moving vehicle. Seems crazy to me!

Sorry old boy, you are mixing fact with fiction and ages old recollections.

A) turning the key off has never ever locked the steering wheel. Try it. You'll prove me right. It must be in park to lock the steering.

B) turning the car off in drive created "engine braking" say if you lost brakes on a hill; as taught in thousands of schools.

How soon knowledge is lost....

Why not zero? Maybe because zero could happen from impact rather than inertia?

Well, I guess I'll have to take your word on that, since I no longer have access to any '60s area vehicles...

But I can tell you that turning off the engine in my grandfather's Olds 88 (trying to sneak quietly home after curfew) took every ounce of strength in my then-18-year-old 3-sport athlete's body to turn the wheel enough to make the turn in the driveway. Sadly, I sabotaged my efforts by coming to a stop WAY too early, and had to re-start the engine to pull the rest of the way into the widened parking area, lest I block my Dad's car... Busted!

Why would it be a big deal to let the ICE come on for 5 to 10 seconds?

I will place mine in low to max Regen braking frequently for the last 1-2 mile to add hvb charge before arriving home. Probably waste of gas.

 

[GPSMan]

It's "no big deal" one way or the other.

It's about learning the way things work, and eventually why.

Gee I think the OP should try it at 75 and let us all know how it goes.

I think I would ask "Gee I think the OP should try it at 75 and let us know how it COMES OUT?

In the older generations of hybrids, you always wanted to arrive home with a depleted HV battery. Why? Because the first 5 minutes of your next start would ALWAYS be run from gasoline. Might as well do useful work and recharge during those first 5 minutes.

Now, with EV mode allowed from a cold start, it really doesn't matter much. It's what you prefer.

Do you prefer to come home the last mile tonight in EV mode? Or do you prefer to depart in the morning for the first mile, or do you care not?

For me, it's colder in the morning, so I want a little heat, least possible in the morning, so I continue with the old paradigm. I arrive home "empty" so I can recharge during those first few minutes if warm up in the morning.

I am thinking that it's not doing me much if any good if hvb is not at (70°F?) or more as ice will most likely be started to warm HVB. I was hoping that bms would have access to hvb to maintain 12v without the main contactors being closed but what I think is logical isn't the way it is actually done.

My driveway ends on a blind curve on a State route with me making a easy right turn (but puts your view of oncoming traffic at a severe disadvantage). It also rains a LOT here. In years past I always opened my door at the bottom of the drive to both look and LISTEN (I drove VW TDI's, not quite cars).
I can tell you right now the Maverick will slam it into park going 6mph if you open the door. I can tell you the truck doesn't like it one bit! Worse yet is on mine the "chime" for it being a EV is very loud (which makes hearing oncoming cars even harder).
It also doesn't help that this is the spot mine looses its brakes (very repeatable). So my nerves are already frayed by the time I reach this spot.
Someone asked "why do you mind the engine cranking up for seconds". Cold motors use more fuel, suffer more wear. So,if your for less MPG's and more wear, then, I guess you'd ask "why do you mind"....
I'd ask why you'd want a car to slam into park while going forward. I guess the only answer is "if someone jumps out the door"... Think about it, if they did that, they would be gone and if in traffic now you'd have your car sliding to a halt among it all. Would be like throwing dice on which way would end up better tbh.

Absolutely not true.

Gotcha, I mis-interpreted the first post

First off I admit this is kind of a bonehead move. Not only did I do it once, I did it twice. I forgot about the first time and "Ops, I did it again."

But I'm curious if you think this is also a bonehead move on Ford's part.

I'm making a thread of this so hopefully I remember not to do it a third time, and maybe You'll never do it.

First Time:
About 6 weeks ago I was getting close to my usual parking spot. I was in EV mode, I knew the battery was low, and the engine was about to come on. I didn't want the engine to spin up for all of 5 or 10 seconds. I wanted to "coast" via momentum into my parking space.

I turned the key off while rolling less than 10 mph, while still in Drive, foot hovering on the brake pedal and/or braking gently.
At 3 MPH WHAM! Truck goes into park locking up the wheels 3 mph to zero.

Second Time:
Tonight, at under 10 MPH I put it in "Neutral" and coasted, then turned the key off because I was testing new equipment. I had a long way to coast, in a wide open area, so did not use any brake pedal at all. Slowed by nature to 3 MPH and WHAM! Truck goes into park while in motion, locks up the wheels again.

Bonehead move on my part.
I won't be doing THAT again. But also bonehead "programming" by Ford?

P.S.

The reason(s) for turning the key off are unimportant here. Software freeze could be a reason.

I'm asking why. Why shift to park at 3 mph?
Seems very deliberate.
Why not 1 mph? Why not 0.5 mph?

We know it works at 0 mph, if you turn the key off at 0 mph. Why not always 0 mph is my question.

THIS is how I wore down the battery on my Buick. Turn off the ignition as I pull into my parking spot, turn off the key leave it in gear and get out like I've done thousands of times with my manual transmission car/truck. But, with an automatic you can't turn the key all the way off till it's in park. So dead battery.

40+ years ago my buddy thought it was a great idea to turn off the engine to his VW bug when coming down the mountain. Little did he know the steering locks when you turn the wheel with the key in the off position in those old vehicles. We clipped a phone pole. Luckily no-one was hurt. The VW was not so lucky.

Interesting but I wonder if the "Old Boy" isn't right after all... Shift interlocks were not mandated until 1992 although some 89' models had them so prior to these years it would have been possible to position the switch to Off in a running vehicle without the shifter being applied to Park. I'd imagine then that it would be possible to turn the key mistakenly to Off instead of Accessory while driving and lock the steering wheel.

That was my recollection as well.

My 1993 motorhome I know I can turn off while running and in gear as it doesn't have a parking pin or pawl but a drum-type brake on the driveline. It can be turned fully to the Off position, while running and in gear and lock the steering wheel.

Unrelated and off topic but while researching this I came across an article stating that in 1980 Ford had a recall for cars and light trucks manufactured between the years 1970 and 1980. The problem stemmed from reports that involved vehicles slipping out of Park on their own. The solution was to mail 20,000,000 warning stickers to the owners of these vehicles.
