Another run away ZS EV?!

Just spotted this news report.

Moment EV 'gets life of its own' & SMASHES into wall after brake failure

AN ELECTRIC car took on a life of its own – smashing into a wall and parked cars after the brake failed. Helen Rees-Jones, 47, has been left “traumatised” after her MG ZS EV went rogue and wr…

Sounds like a case of user error? Coincidence that the first reaction again is "I'll never step in another EV car"?!

Just more anti-EV tripe from a tabloid, I'd say.

Didn't Toyota go through a world of pain with one of their ICE cars with uncontrolled throttle opening killing people?

Will anyone post news articles showing the number of ICE vehicle uncontrolled throttle opening and fatalities resulting from that, and a comparison of the same thing with EV's and the resulting fatality count from this same problem .......

I understand the airbag modules in a number of Aust vehicles, store the throttle position and brake apply pressure ..... that can be and is downloaded by insurance companies where the driver story is different to the observed accident scene.

I'm guessing, if MG could download this information, they might have a claim against these tabloids for spreading incorrect information or suggesting that something happened caused by the vehicle without driver input .....

Totally agree! When will it end?!

I suppose it is more comfortable to think it is driver error.
Certainly it could be, but then two Boeing 737maxx crashed due to faulty software....

“I turned to the right to avoid the wall I was pulling up to. I probably had my foot off the accelerator.

“I went to hit the brake but there was nothing.

“I was just slamming my foot down but nothing happened.

“There’s no handbrake nothing to stop me.

Really ???? Yeah, right ...

The faulty sensors and the software not recognising the faults resulting software contributed to the crash, pilot error as a result of poor pilot training caused the crash. All the pilots previously flying those aircraft had had reported the problem, but know what to look for that were the signs something was not working the way it should, so they disabled that pilot assist .... the crashes were the result of pilots not understanding what was happening and turning the pilot assist off.

Definitely a software issue, there should be enough sensors to recognise the nut behind the wheel is the problem and simply slam on the emergency braking and open the door .... a message running across the screen "the system has recognised a serious fault resulting in a situation where an accident will be immanent, please exit the vehicle so it can return to a safe operating condition"

Also a well known computer error, techs refer to as PEBCAK issue, "Problem Exists Between Chair And Keyboard"

Yes, the word 'probably' doing some heavy lifting in that quote.

My experience of the ZS is it definitely has a few software hiccups.
I always set the ACC when going to Sainsbury's as it's a 20mph limit all the way. Yesterday, on turning into Sainsbury's I pushed the ACC lever forward to stop the cruise control, it kept going, nothing in front of me incidentally that it had latched on to. I braked as I hit the mini roundabout, the brakes worked, but the ACC didn't disengage. On leaving the roundabout, I hit the brakes again, and it worked.
I'm not saying that these stories aren't fabricated on some level, but it makes you wonder if there's equally some truth behind them too.

I'm with you with the software glitches, but one thing I think is guaranteed - when you hit the stop pedal it stops. I don't think it would still be on sale now if that wasn't the case.

The only exception is when the ACC radar is "locked" onto the car in front as mentioned by dspencer12345. Even if you hit the brake pedal and cancel the ACC, the radar will still be locked onto the car in front and control your speed. It's the one feature of the MG Pilot I really dislike.

Was the ACC light green or yellow on the dashboard?

that never happened to me... I don't normally use ACC as it's pain in the neck to depend on the driver in front or dodgy road/weather conditions but when I did use it on M25, it always disengaged fully ...

For throttle yes - but brake overrides everything in ALL circumstances, even that one.

Not on mine it doesn't if the car in front is also braking, then the radar remains locked on to that car. Only when you tap the accelerator pedal does the radar stop reacting to the car in front.

You can tell when the radar has disengaged when you see the power go negative when the regen kicks in. Otherwise the power remains on zero, even when you think regen is slowing you down, it's the radar using the brakes.

 

[Tim Green]

I have never known my car not disengage ACC when the brakes are applied.
However, that is dependent on the accurate working of a cheap limit-switch.

the instructions manual says that the accelerator will override speed limit on ACC but as soon as you let go, it will automatically go back to the speed/follow setting. if you break, everything should disengage and not go back onto ACC or follow the car in front ... if not, there might be something wrong with yours that needs checking?
(unless we are not understanding each other about what happens when .. )

Not so! My damn MG 4 took off after I stepped out of it, having put it into Park, with the confirmation lights illuminated, and the door open. VW e-Golf had same problem. Very dangerous and impossible to occur with an ICE car. I didn't even get the audible warning of an open door. Dealer's response, "Oh, well that shouldn't happen".

Didn't Toyota go through a world of pain with one of their ICE cars with uncontrolled throttle opening killing people?

It was the Prius, so a Hybrid, not an ICE.

 

[Gadget Geek]

I'll try and clarify what happens with my ZS.

When you brake or disengage the ACC, the ACC does disengage and the car slows down.

However, if you brake or disengage the ACC when the radar is "locked on" to the car in front, if that car is slowing down, my car slows down with it without the expected regenerative braking.

If you brake or disengage the ACC before the car in front starts to slow down, then regenerative braking kicks in and my car slows down on its own, regardless of the car in front.

It can be quite disconcerting when you expect to slow down, and the car in front keeps going. If the radar is still locked on with ACC disab;ed, my car also keeps going.

Not dangerous, because the default is to slow down and stop, just unexpected and annoying.

 

[Roldorf]

Getting out of your car without hitting the stop button is not recommended, and the car will warn you if you do that.

 

[DB Go Rex]

Not on mine it doesn't if the car in front is also braking, then the radar remains locked on to that car. Only when you tap the accelerator pedal does the radar stop reacting to the car in front.

You can tell when the radar has disengaged when you see the power go negative when the regen kicks in. Otherwise the power remains on zero, even when you think regen is slowing you down, it's the radar using the brakes.

So you are saying if the car happens to be braking under ACC and you brake, there's no response and no cancellation?

I'd be shocked if that's the case, I'm pretty sure you'd get the braking you ask for and a cancellation of ACC - that's my experience.

I would report that one to MG if you think that's reproducible.
