MGS5 safety software fault - recall level problem? (reverse after hard stop; merged)

[Ian Key]

I was thinking of saying something similar. I don't know how to contact MG about it and the dealer doesn't have a clue.

Reply from DVSA:

...so at least we have documentation for use after a child in a buggy dies.

So MG get to mark their own homework.... nice...

 

[decrep]

officialdom evading work. Surely those vids are clear enough evidence of a real problem!

No doubt, after the children are killed, there will be an inquiry and "lessons will be learned"…

We had to do an emergency stop today while using one pedal drive and I am happy to say this didn't happen for us. I had been meaning to test it out and see if we had the issue but never got around to it. Today we was forced into it - 100% brake at around 40mph and it came to a complete stop, auto held and no roll back.

So it seems it isn't a problem with every car.

Hi all, I have had my MGS5 a week and I stumbled upon this issue quite by accident today. I almost rolled into someone behind, but as commented, it was more than a roll, it was being powered backwards. I think the mention of applying the brake, and most people wouldn’t take their foot off is a slight red herring. In my case I was using OPD and the car had come to a stop by virtue of me taking my foot off the accelerator and slowing down well in advance of reaching the car in front. Once stopped it went backwards and I had to quickly reach for the brake, this isn’t good enough and needs resolving without delay. Is there a fix? In addition, has anyone else had issues with auto high beam assist? Mine won’t work half the time and when it does I get nothing but horns, because it is either too slow to dip or sometimes puts the beam on when moving cars are coming past!

I have it happen on a very regular basis. I still forget between times.

DVSA have told us they don't care. I guess we just wait for a fatality or two...

 

[Hankydoo]

So we have to pay to have it investigated by an MG approved repairer, and as someone says, they then mark their own homework! Unacceptable. Surely if enough of us raise an issue under warranty they will have to provide a fix?

It was also reported in a Dutch review, though it was a downhill related stop. Not an emergency stop. But the reason is the same.

 

[Hankydoo]

Imagine if someone was walking behind your car at the time crossing the road thinking you had gone past. Also whose fault is it when you reverse into the car behind... I can't see anyone being convinced by "Sorry not my fault, it's a quirk with the car".

Playing devils advocate. Those of you who have commented on here or elsewhere that you have a problem with the car rolling back when using OPD if you do have an accident when this happens you won't have a leg to stand on. Why knowingly stop using OPD when you know it can roll back without applying the foot brake?

I, for one, am conscious of the fault and will stop the car before it kills anyone.

I am more fearful for the people pushing buggies behind someone who is not aware.

 

[dx4100]

Just wondering how many people immediatly cross the road behind someone who just emergency breaked

The mostly likely situation is someone didn't keep the 2 second gap behind you. Thats a them problem.... Unless they have a dashcam

 

[TimothyN]

To be fair, the speed at which it goes backwards is not going to dent a bumper. It could knock over a child who then bangs its head, though.

 

[decrep]

If it's an emergency stop, the person behind could be getting very close anyway, if their car is going to hit you, the power back will make the impact all the harder.

If you keep your foot on the brake after you stop, does it still roll back, when you take your foot off?

 

[Hankydoo]

When it did it for me it wasn’t really an emergency stop I don’t think it has to be.

 

[NLMGSAN]

Are you guys seeing it regens 25% when it happens? Engine plus brakes for a stop?
The MG4 received an update limiting regen to 20% with regen only (I think). Since then I did not hear much about it anymore.
