Sudden automatic braking issue (merged, MG4)

[tsedge]

Well here’s my opinion not in any vehicle should anything that might affect the actions of that vehicle on the road default to On.

You are the driver and you should decide what is right or wrong for your journey, when a vehicle brakes suddenly and unexpectedly that might, cause an accident in some circumstances.
Or the steering on the vehicle decides it is going to turn the vehicle left or right and might run you into an oncoming vehicle or a lamp post, it will be you the driver that will be standing in the dock or by the grave side, not the software that might have cause it and not the person who designed it.
Not the NCAP people who demanded it. To some box.
No it’s you.
The driver should have total control of the vehicle they are driving at all times from the start to the Finnish of there journey and it is the driver only that is responsible for the action of the vehicle they are driving.

DEFAULTS don’t count.

I agree Les, I really do. It is the way things are heading sadly.

Thanks tsedge and I agree with you also it’s the way things are heading but I’m not sure it’s a good thing when a Tin box you climb into with your loves ones decides how you the driver must drive it.

You know I could understand if the powers that be had said all cars now must be fitted with speed signs recognition many are nowadays and it must default to on and the vehicle will automatically keep you at that speed, but no they put a number in a circle on the dash and if it’s flashing your going to fast for that stretch of road, so you the driver have to decide if your going to slow down or not I know if that was the case it would drive us mad but that would reduce accidents Im sure, Statistics have already proven that to be the case.
LKA and unnecessary emergency braking might work the other way in my honest opinion.

Hi Jim but please correct me if I’m wrong you, I seam to recall are drive a MK1 SR MG5 the same as my first one and if so this car was never fitted with this software I don’t think, so it can’t happen in that model I believe.
Les

No, I have a 2022 LR. It definitely has the AEB because there are settings for it in the menus.

 

[Les burrows]

Apologies Jim my mistake

I think I got this - I was stopped, indicating to turning into my local lidl car park and it braked . Is there any log of these events ? How can I confirm it was this - its disconcerting.

It dead right Jerry disconcerting it is. I don’t know of any logs that the owner can access maybe dealer can I’m not sure for this.
Did you have TJA ( traffic jam assist )or ACC ( automatic cruise control ) engage by any chance as this can effect it in this way

yes, I think TJA might be on. I've just left everything the way it was set from the dealer. leave the techy stuff for next weekend.

Could not agree more with this. We should be able to have total control, and cede it voluntarily as we wish. Since the AEB defaults to 'on', I have to deactivate it every single time I turn the car on, and if i forget, I run the risk of it emergency braking me for no reason and potentially causing an accident, which is unacceptable. I understand the legal rationale, but as Les says, it's not MG or its designers who will be standing on the side of the road somewhere with an angry driver who's just driven into the back of us or arguing the toss with some incompetent copper (as happened to us with our last car) debating whose fault it was.

Wait until the auto high beam flashes the car yards in front of you, as has also happened to me in my 4.
Then they’re the one slamming the brakes on thinking you want some road rage.
In your case and mine, we’re both left saying ‘sorry it was the car, not me’

Driving out of a Morrison's supermarket at the weekend my MG4 suddenly decided to [for the want of a better phrase] emergency brake. This happened once before in the new year, but I out it down to a one off. Fortunately there was no one behind me, but it did give my passenger and I quite a shock. It was at an exit point with a street bollard nearby. I wonder if somehow the cars system my have mistook the bollard for a pedestrian, and if anyone else has had this problem/reported to a dealer? Once I've had feedback I can then discuss with my dealer. I'd appreciate any feedback from anyone else who have had this happen to them.

MG4 EV Trophy has recently done a similar thing. Whilst driving at 20mph without any other vehicles or pedestrians around it suddenly applied the Emergency Brakes. No verbal or visual messages displayed just the sudden stop!! Nearly caused an accident with the car behind. My car is now back with the MG technicians and is having various software updates completed?

My emergency automatic breaking system has engaged twice for no apparent reason - once when trying to turn right and the second time on the approach to a roundabout. I was no where near the car in front, my foot was not on the break and the forward collision warning didn’t come on the car just did a full on emergency stop out of nowhere - luckily no one went into the back of me, obviously this could be dangerous should this happen on a motorway for example. Has this happened to anyone else?

 

[Norfunk]

It happened to my wife driving her car this morning doing a right hand turn at traffic lights the car did a full emergency stop. The person behind her was paying attention luckily otherwise this would have been much worse. It shook her up.

Unfortunately this is the state of AEB across most manufacturers at the moment. They rush to add it for the NCAP points but the technology is immature.

You can switch it off.

Ive had my first AEB, no car in front but there was a pedestrian on side of the road. It was a full on screech with tyre smoke for about 1 sec and then it released. Luckily the car behind was way behind me but the pedestrian needed new trousers

Was it merited then with the pedestrian in the road?

Not when they are on a footpath no!

Thanks for everyone's comments. Can I turn this iff in the MG Pilot menu's? If so, could anyone advise me how to do this, and if advisable to book into the dealer to look at this?

 

[siteguru]

Why book into a dealer? They'll not be able to turn it off permanently.

Go to the Home screen, click the Car icon (might need to click Settings first - I'm not in my car and can't remember) and the Auto Emergency Braking is a setting somewhere in there.

Never happened on my Kia Sportage GTline-S, LKA worked properly as well.
