Uncontrolled/Unintended Acceleration on 2023 MME while using single pedal drive **SAFETY ISSUE**

[AliRafiee]

Yeah, unfortunately for the OP these things are pretty common and so far every single one was one of two things-

1. they accidentally hit the accelerator
2. They accidentally hit the resume button on cruise control

It’s not a coincidence that these same exact scenarios always happen when pulling into or out of a parking space.

It’s called an “accident” for a reason. Zero chance the OP is going to find some proof otherwise. Even if they had a dash cam and videos of their feet, all you would see is them accidentally hitting the gas when they thought they were on the brake.

It sucks, but these parking lot gas vs brake things are very common with all cars. I’m kinda surprised with 1PD it doesn’t happen more often since you train yourself not to move your right foot.

That’s probably the reason the application of brakes was never registered in the car computer

I have a 2023 Mach e premium on lease.
I drive using single pedal mode.
Three days ago I pulled into a parking spot in front of a restaurant in a plaza. When I took my foot off the accelerator the car came to a complete stop (as it should have ) … about a half a second later, before I could put the transmission into park, the vehicle went full throttle and jolted forward up over the curb onto the plaza sidewalk and crashed into a full brick column. I slammed on the breaks as fast as I could, but if the brick column was not there, we would have crashed into the restaurant.

Have you ever seen a "1 Pedal Drive Fault - Press Brake Pedal To Reduce Speed" warning message in your instrument cluster, combined with 1 pedal mode deactivating and the car reverting to 2 pedal mode? If so, that might be a factor here if it very unluckily happened right as you were parking.

Since you didn't mention it though, Mach1E's summary above most likely contains the explanation. It sucks and I'm sure was a very scary experience, but hopefully your car insurance will take care of the repairs.

There is damage to the front drivers side of the vehicle. The airbags did not deploy. The beeping sensors never went off. Honestly, the experience scared the crap out of me. We’re lucky no one was injured.

Ford has the car at the dealership now.
they told me that something seems to have malfunctioned. They told me that the car should have deployed the airbags, the sensors should have went off, a deceleration stamp should be logged in the vehicle data and it should be telling ford that the car experienced a collision. None of that happened.
needless to say, they are now telling me that because they can’t mimic the problem, Ford is instructing them to return the vehicle to me.
they have nothing to repair, and are not taking ownership for the damage.
I honestly don’t want to take the car back.
my wife isn’t comfortable driving it anymore as she feels it’s a safety risk.
Not sure what to do. .. thanks

I'm probably doing it wrong, but I have used 1 pd almost 100% of 60+k miles. When I park either with the brake (seldom) or by taking my foot off the gas pedal (auto hold on) I turn the car off which immediately puts it in park and alleviates the possibility of putting your foot on the brake and accidently hitting the other pedal.

That’s what do. If I want to leave the car running, I just open the door.

One nice thing about Ford's standard "Red Carpet Lease" terms, as my finance guy put it, "if at any time you no longer wish to lease this vehicle, you can walk right into the dealership and hand them the keys"...

I imagine this can’t be true .. ??

While all drive modes are equally efficient, in my opinion the dealer was correct.

1 pedal drive does give the best driving experience overall.

Also, using 1 pedal drive encourages you to modulate the pedal slowly when ‘braking’ which increases your odds of using regen vs. friction brakes. Slowing down more gradually will decrease the need for the vehicle to blend in using friction brakes thus increasing your chances of recovering some energy. Could you simulate this using 2 pedals, sure but it’s easier with 1 pedal drive.

I REALLY REALLY wanted to like 1 pedal drive, I tried it with both mach e's and I just didn't like it. To me it feels like surrendering too much control over driving and increases potential inattention. It's only my opinion and apparently I'm one of the few that thinks this way.

Dealerships lie? I got low-key scolded for questioning their integrity in this thread . This is what my finance guy said though I haven’t tested it. Maybe ask yours what an early exit would look like?

 

[rreddy3]

What matters is what the lease agreement says with respect to early termination of the lease. Your dealer finance guy may be correct, I don’t know, although a no fault, no consequences walk away sounds a bit unusual.

Typically, at least in the past, if one wanted out early there was a buyout of the remaining term. But maybe in the current market, EV lease terms have changed…or not.

I’m not sure how using 1P is relinquishing too much control to the car. If, in the rare occasions, it doesn’t do what I want, I use the brake pedal. As far as moving forward goes, it has never done anything I haven’t told it to do in the last 3 years.

in my area there are a lot of hills, when using 1 pedal i am always using pedal or it comes to a stop, 2 pedals my car glides down the hills ….am I using less power when gliding down vs 1 pedal?

It's relatively easy to feather the throttle so that a car glides downhill while using 1pd drive; it just takes a few minutes of practice. Contrary to some folks' apparent opinion, the throttle doesn't have to be fully open or full idle.

And a check for the balance of any remaining payments.

You’ll get a bill later for any excess mileage/wear and disposition fee.

It’s not.

What was described is a voluntary surrender, which would go on your credit as a repossession.

Looks like the disposition fee is waiverable and the excessive use fee is going to vary based on mileage. I'm betting you'd only show a repo on your credit history if you were behind on payments when you terminate the lease. Bottom line is, early terminations happen regularly when people trade-in or whatever and the exit terms need not be punitive. Only way the OP would know how much it cost to get out would be to ask.

I do strongly suspect the unintended acceleration was less of a software glitch than a "squishware" glitch (human error), but I admit to having no basis for this conviction (other than the bitter prejudice against humanity which has taken root and flourished within me throughout the course of my lifetime ).

The few instances of unintended acceleration or deceleration I have experienced in my first 4,500mi of MME ownership so far, have all traced back to errors in Ford's "Speed Sign Recognition" system coupled with the "Predictive Speed" option in my Adaptive Cruise Control. Once in a while (say, when driving past a 20mph sign in a school zone), the Mach-e will hallucinate the 60mph speed limit sign it wants to see instead of the 20mp sign it actually should have seen. The system prolly works right about 98% of the time, but when you drive past that 99th or 100th sign it can get a little over-exuberant or jam on the brakes unexpectedly...

Yes some fees are waived if you buy another Ford.

But what was described as turning in the keys and walking away is not an early termination. If you take the car back and just drop it off, that’s a voluntary surrender (repossession). It doesn’t matter if you are current or past due on your monthly payments at the time. What happens is the car goes to auction. If we get more than is due the customer gets the overage. If the net proceeds from the sale are less than what is owed then the customer is required to pay the remaining balance.

An early termination is trading in or paying the remaining balance, not just dropping it off.

Yes the OP could ask the dealer or call Ford Credit for the termination amount due.
