Merged thread: Automatic Emergency Braking activating for no reason

[GameZone]

Have anyone here asked your dealer if there's an update to improve this?

 

[Matt x power]

Mines only done it when using ACC

 

[PeteC]

I'm pretty sure that mine used to stay on low sensitivity but now it defaults/resets to medium every time I start the car. Not that I've had it slam the brakes on yet.

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.

Totally agree here. My mg4 is getting picked up tomorrow and taken back to the dealers. If its not trying to steer me into on coming traffic its emergency braking for no reason. Its new name is Christine ??

Drove the wife's Aygo X today with her as passenger. She s**t herself and shouted at me for breaking her car. It stamped on the brake when I tried to negotiate parked vehicles on both sides of the road which I would have been able to drive through in my 4 with no issue. So it's not just MG or even EV's that do inappropriate automatic braking . Also the LKA is just as annoying as my 4 . Made me realise how nice the 4 is.?

I'm first at the lights when lights go green. No oncoming traffic so I move half way around the corner and BANG.
Car slams on brakes for no reason. Take my advice guys turn the emergency collision off. I was lucky there was not a car around. Love the MG4.

You didn't say if you were turning left or right. With your experience and a little hindsight can you think of anything which could have upset the camera/radar, sun shining on wet white lines for example, or as the car was going around the corner the camera was sweeping at a relative faster pace? This forum could use any useful info.

And yet many people never experience this. I wonder if it's some sort of setting issue, maybe a camera that needs aligning?

 

[spoton]

To be honest I would prefer my 50 years driving experience over a software program that no manufacturer in the industry has mastered. Remember people have been killed in the USA with rear end hits only a matter before it happens here.
Trust your judgement until the technology can prove it's better than you.

I was turning right and the only vehicle on the entire junction. If it was a camera or radar problem then at the moment it's not fit to be enabled.

 

[Martinonline]

Unfortunately Governments believe that technology hardware and software will overcome all without subjecting it to real life conditions, in order to appear to be 'doing something'. The example being ICE car emissions. Manufacturers seek ways to side-step regulations whilst appearing to meet them. Until independent real life testing is used combined with published User feedback, the status-quo will continue.

I can only say again what i wrote at #20 & #22 on this subject and this should not be happening In any car and I agree with Spoton it’s only a matter of time before it kills someone but I sure hope I’m wrong on that.

The thing with these systems is that 'objective studies' do show possitive effects. But those are extrapolated effects to all road users. There is no discussion about the exceptions: when the systems fail. In some case they scare the hell out of you, in very rare cases they might cause casualties. But overall.... the average is what makes the policies tick.

The manufacturers know this. All of them. Look at the manuals and read the chapters about those safety systems. The most important part is about responsibility: it is you. The driver. Next, there will be lists so you know when these systems may not work properly, or when they simply are bound to fail. The latter coincides with a strict advice to disable immediately/asap etc. So if anything happens, you are the moron. After all of this, then they will describe what these system are supposed to do.

This is why any button, how deeply hidden in the systems it may be, will always allow you to disable them. If they take that away, you can no longer be held responsible in general and that is a risk manufacturers will not take.

What we are currently doing is describe events where these systems either blatently fail or intervene with a better response from the driver. They are anecdotical of nature, poorly documented and easily classified as 'subjective and flawed observations', as well as suspect of poor use. On the other side we have goverments, regulatory organisations with an eye on the big numbers (such as NCAP), insurance and car companies (with an eye on big 'numbers' too).

For things to change we first need a number of deaths and a string of law suites. Unless systems drastically improve. Than the issues will fade away.

I have it and LKA permanently disabled but that doe not say I should not understand how it works or as in this case does not work. For it to work it has to recognise certain parameters within its programming , but on the road these can be replicated just due to the multitude of variables which are present. One of these could be poor alignment as Rolfe suggests , others have had issues crossing rail lines , parked cars etc. Indeed the manufacturers do not have much faith in their products, they probably feel that this has been forced upon them, with all their warnings of ultimate responsibility in the user manuals. Given that ,they do not mind the extra profit margins the 5 star safety accreditation gives them. But it does end up that we are paying for extra features and extra servicing costs for things we never use.

I have it and LKA permanently disabled

There are a lot of drivers that keep LKA activated. And it is quit logical too. First, they probably do work most of the time. And if you use a car in similar circumstances every day where these systems cannot be fooled, why should you disable them? I also hear people say 'I have it on all the time', forgetting they rarely go over 65 kmh when going to the groceries....

Then there is difference between modes. So if by any chance you always set LKA on but select Alert or to LDA (the latter only makes mild movements on the steering wheel), you will not suffer much from LKA. The worst one is ELK, whatever software version you are on. That is the one mode applying more force when it observes 'an emergency situation'. The combo of a wrong assesment of the situation and a strong intervention on the wheel is when drivers sense a feeling of loss of control. Which is opposite to what these systems are supposed to do.

My personal experience adds another one. Wheather was fine. LDW was on (I disable ELK by default). Driving on the highway with ACC at 100kmh I drove the car into a long bend. So the car slowly moved to the edge of the lane (clear solid line). These outer lines create a rumbling sound when your tires touch them. I heared the rumble. So I was like Huuh? I corrected the car. I checked the menu and for sure LDA was activated. A couple of km's later I tried to replicate it but I could not.

A glitch the dealer said. Unreliable I said.. From that moment, I only use Alert. This is the only system that fully and always depends on my own steering capabilities, yet 'attempts' to help me observe.

The same may soon be applied to the forward collision system if it hits my brakes without any reason.

So yes, give me a 4 star MG4!

 

[AndyL61]

Is it just me ? I don't like LKA , and as such have always turned it off on any car I have driven with it fitted. However when I have occasionally forgotten and it has activated, at no point can it over power the driver , you are stronger than the system and you can control where the car steers to. Yes it can be surprising but as soon as you hear the warning, see the display or feel the twitch you can over power it . Like I said, I choose to turn it off because I simply don't like it but I could never seriously say it could kill me.

 

[TerryN]

Indeed, it's the surprise element that I find most annoying. Especially when it kicks in when you're concentrating on trying to avoid something in the road.
I always turn it off (when I remember)

 

[NLMGSAN]

I'm not saying you can't. But there is clearly more resistance against your own steering. Do you happen to have the SE? Because as far as I know it doesn't have all three modes

No I have a Trophy, the point I was making is dislike it as I do I cannot say it could ever be capable of killing me as I can over power it , so yes it is annoying but not the dangerous potential killer some people keep claiming.

 

[tsedge]

I've seen no evidence of anyone being killed by LKA. There are several people claiming they had a crash due to it, but without dashcam evidence it is hard to be sure.

I turn it off every drive, I like to steer myself without help.

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.

Roundabouts. My MG4 hates roundabouts it brakes randomly on them and scares the crap out of me. But then you get on to a straight stretch of road and all should be well! Till the LKA (let's kill you any way we can) cuts in and diverts you into a wide load. I really love my MG4 but the bugs really need addressing.
