Reverse while vehicle is in drive

[Ford Motor Company]

The car has been with dealership today for testing and for updates. They haven't found anything wrong yet. They will continue testing tomorrow.

I double checked the dial so many times. Ofcourse when something like this happens you don't think it's the cars fault. But the D was lighting up on the screen as well as on the dial. The car just wanted to go backwards. When i did get it out of the slot we noticed that it went back a few meters before starting going forward. This happened many times. When i woke up today and drove it to the dealership everything was back to normal.

One other oddity that was occuring during this crazy situation was the signals for going left and right. They usually make this ticking sound in a Rhythm. While now they were completely off sync, jumping over beats and sometimes doing a reggaeton beat.

Also i was getting error messages for the reverse braking guidance.

Hey there! I can look into your Mach-E’s concerns on my end if you’d like. Will you send us a private message with your VIN and dealership info?

I own Mach E SR RWD - build February 2021 (Netherlands)

I thought I am the only one who experienced this problem - it happend 2 months ago.

I stoped the car for probably 5 minutes, I parked facing a wall (approx. 50cm apart). Started to reverse (R-Mode) but the car started moving forward, it was about to hit the wall. Tried different combinations N, P and another try to reverse (R) but same problem the car was moving forward in R mode. I had no more space to go fwd so tried to manually push the car back in N, but could not move it further.

Switched the car off and tried again. but same thing still moving forward in Reverse mode.

if I remember correctly, I was also not able to remove the parking brake when this issue happened.

I had to call the ANWB (Vehicle breakdown assistance), it took 30 minutes before help arrived, with some help we moved the car further back in N, tried to stop/start and then it started working normally again and I could reverse.

ANWB guy checked all previous complains if any one experienced such issue but looks like I am the first person in Netherlands to experience this strange problem.

It is already two month since this issue happened and the car is driving normally, I have not experienced this issue anymore.

I had this happen the other day. Backing very slowly out of my garage, squeezing past another car. Stopped but did not shift. When I resumed OPD'ing, the gear selector still showed "R", but the car moved forward till I slammed on the brake. Looked again, "R" was selected, took my foot off the pedal and the car moved forward (uphill). One more time - same result.

I shifted gears a couple of times among "P", "D" and "R", and the problem resolved - I was able to select "R", and actually get reverse gear.

I looked carefully several times, so I can swear under oath:

1. The car shifted itself from R to D - I had not shifted it, and
2. The car showed the wrong gear selected.

Disturbing. No damage this time, but certainly could smash the car - or much worse, a pedestrian.

I have high confidence that bringing it into the dealer would be a total waste of time. Will just have to be extra careful in case it happens again.

I had a similar thing happen the other day to me, going between D and R.

Did anybody here get resolution on this issue?

My Route 1 is at the dealership now for the same issue. This happens to me when I'm backing out of my driveway on a slope - it seems to be super specific to what angle the vehicle is at, but it's very consistent that it continues to go backwards even after switching to D. The motors do seem to make a straining sound when it happens, so it's clear that there is a conflict between signals and mechanical response somewhere along the line.

Dealership said that there are no error logs and no open service bulletins with Ford, but they are going to continue looking at the car once they get some space to lift it. If anybody got an answer back, I'd love to point them in the right direction.

I think there might be two different problems, one is the actual motors being driven in the wrong direction from what is commanded and displayed, and the other might be if auto hold is not working properly.

I have seen strange response if vehicle is on flat surface, but just one wheel is placed such that it wants to move the vehicle in one or the other direction, and in those cases auto hold seems to not be active (auto hold is enabled regardless of setting if one pedal mode is active). It might seem like a "false" case of the same issue. If vehicle is on a flat surface it seems to not enable auto hold by keeping (friction) brakes on until there is enough torque to move, which makes sense since it probably tries to calculate it based on slope degree.

The case I had where it actually moved in the wrong direction it was not a case of auto hold, it moved significant distance in the wrong direction before I turned off one pedal mode and it immediately started going in the correct diretion. I have never had this issue after this incident, but several cases of the other (which I do not consider an issue)

So toggling 1PD may fix it.

Can you push this vehicle in neutral? Or does it need to be in L or tow mode? Sounds like a rare occurrence so far. If it happens and it gets too close to something I want to be able to try it again. Never thought I would try to push this heavy beast but maybe we should know how. If you exit the vehicle to push it I think tow mode would be required? Get out the passenger side in neutral?


Edit: link guess if I did car washes I would have known.

This is alarming. One thing not clear here is whether these incidents are all relatively recent, regardless of build year, or if this has happened to owners of '21s & '22s a year or more ago. If all of these incidents happened recently to all build years, could a relatively recent OTA update have been the issue?

They need to update your PCM to fix it. I reported this bug (I think it’s the same, mine would roll backwards downhill in 1PD without braking) months ago and it was finally fixed in the latest powertrain release.

Does not sound the same this is it goes backwards with drive selected or visa versa.

The bug seemed to prevent forward torque output when rolling backwards down a >5% grade faster than 5 MPH. Being in drive would have the same effect as 1PD because forward torque would be commanded in both situations.

Either way, if the PCM is not fully updated that should be done first and the vehicle re-tested on an incline.

Thought I read flat and both ways ?‍ People should give sync version may not be perfect but a ball park.

My particular experience is backing up a slope, it's jarring because the vehicle should want to "roll" forward, but even when pressing the accelerator once in D it's actively moving in reverse. Neutral rolls as expected, but interestingly even going to D after N first the accelerator still moves the car in reverse - only going back to P seems to "reset" things. Haven't tested it facing the other direction. Will mention PCM to the dealership while they have it.

I'm on SYNC 4.0.23031

I think I've had this happen before but chalked it up to me not being used to the rotary shifter dial.
