My MG4 Trophy has done it a couple of times when I was reversing into a parking space and I thought I had hit something the car stopped so quickly. You do feel like you have hit a brick wall. Especially embarrassing in traffic.
 
After a month and around 3000km I finally had one yesterday what I barely could explain. I'd like to blame the car, but after have another go on the same spot I realized that was me... well, at least what the car thinks.

Slight uphill right bend, narrow road, but good size lanes to both direction for one car. Someone parked on the left hand side of the road (my lane), and I noticed the upcoming car. So, I slowed down, put my indicator out to the right, and bam... the car stopped on the middle of the hill, road.

No traffic behind me, so at least nobody hit me.

The issue what I see. The car saw the parked car on the side of the road, the centerline, and the oncoming vehicle. Also noticed my speed (about15km/h at the time) and the activated indicator. Top of that, I presume, noticed the steering wheel was off center (right bend). Conclusion "...this bastard, wants to hit the oncoming car. I have to stop him..." so it did.

Unfortunately it will not boost my confidence and the trust in the "safety" features of this car, this is pretty much what I would do in any similar situation as I had plenty of space to slow down without a complete stop and roll back to speed after the coming car has passed.
So, dear software engineers at MG. Please, put some testing in to the R&D process... It would bring up a whole bunch of problem before the product hits the market and I can tell, costumers can be happy (or at least less frightened).
 
Great car, like the LKA alone wasn't enough to get you killed, you also have emergency braking which could get yourself and others killed.

Yep...I was really keen on these but that is one of the reasons I am going to pass on a purchase.
My wife and I just want a car that you can just get in and drive without worrying about turning dodgy 'features' off.
That and the fact that they are awkward for me to access and exit due to my declining years, but that is on me and most owners probably find they are fine. ;)
 
I hope you find a car that suits. One of the problems seems to be that new cars are all like this to some extent or another. The best you're likely to find as far as LKA is concerned is a single button-press to deactivate it rather than the MG4's complicated rummaging around in the infotainment screen.

Most people don't seem to have a problem with the emergency braking on the MG4, and it's something that seems to affect quite a wide range of cars. I have a suspicion it's actually something to do with camera or other adjustment in individual cars, rather than the MG4 (or indeed another specific model) as such.

But the LKA on the steering wheel could easily be fixed

Me too. I got out to find what I'd hit & found nothing. It just went bang and stopped. I put it down to some weird anomaly & then on a trip I was reversing into a charger & it did it again. Same thing jumped out, had a look, found nothing & continued in to the charger. It was only then that the penny dropped that it was the auto emergency brake. I have no idea what it detected. There were no pedestrians or bits of rubbish etc being blown about.
 
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.
I believe I know what is going on.

In very slow traffic or coming to a stop, sometimes we let the car creep forward without having our foot on the brake. The car thinks it will hit the car in front and will emergency stop. This is more disconcerting than dangerous since the traffic is moving very slowly.

Solution, don't let the car creep forward. Cover the brake pedal with some small pressure and it will not do so.

I've had two false AEB activations.
In both instances it was when I was in the city overtaking parked bus and truck, where I moved into the oncoming lane with slow moving traffic and enough room to move by.
I think they use vehicle lane assignment for this feature. So it detects that I am in the same lane as the opposing car and it activates, regardless of the amount of extra room there.
I know what is going on. If you try to overtake a car by going into the opposite lane and a car is coming from the other direction the car TRIES to help by braking. To be frank most times this happens I should have waited. Anyway, if you think you have enough time to finish your manoeuvre just indicate first. If you indicate the car will not react.
 
I'm pretty keen on the reversing radar. I've never had anything like that on a car before and I'm using it a lot. Not least, to tell me when I'm in the garage with enough space behind the car to walk past to get to the granny lead. I wouldn't like to lose it.

I just turn off the LKA before I start and try to like it. Maybe if I'd had an issue with the EBA I'd feel differently, but I haven't. I wonder if something needs recalibrating in cars that had that problem?

I doubt it's a calibration issue. Too many thing works oddly, so this is rather the result of early 2000's "Chinese ingenuity", remarks rushed market appearance, before they truly tested the product. I still have the reversing camera, so the radar isn't an issue. I think I'll stick with this, and stop complaining until MG came out with a fix to these bugs. Really nothing else out there to my taste to replace it...
 
I'm with you on the no acceptable alternative part!

I'm just curious why your car seems to be behaving worse than mine, when they are essentially the same model. Or is your main gripe the LKA? Because it is mine.
 
Well, LKA is one of the issues I have, but that is the most predictable. It's s*%# all the time. EBA is different, in the sense of random occurrence. ACC and TJA is fine on a straight highway/motorway, however we don't have many around here. Using in traffic... I understand now why people leaving 2-3 car gap between the vehicle front of them, and roll behind them with very "cautiously", which is really annoys me (the traffic jams here is not even close to big cities in Europe, and a bit of attention could dissolve it completely, but not with "features" like the TJA in my MG). The rest of the electronics is the same. The worst part is, when I asked my dealer about the heating, for example, he said "oh that is the way how it should work" (it cannot maintain any set temperature when heating function is involved, overshoots, then turn the AC on to cool it back). So I concluded I have to sort it out myself... they will do nothing anything about it.
Yes, I might have too high expectation, but I would appreciate functional features. When I decided to switch to EV (this is my first one, as you might can tell), I prepared myself to compromise on range, travel planning, travel time etc., which is fine and I can deal with these. But to be fair, I expected all, I'd call usual features work as they should, and as they worked 10 years ago when first appeared in mass production (OK some of them 5 years ago).
 
I'm just as new as you are I think. I also hate the LKA and turn it off. But I don't have any issue with the emergency braking, and my heating is absolutely fine. I have heard others complain about your issue though. Does your car have a heat pump?

My feeling is that if other/most cars do not have your problem, you have a fixable issue that your dealer needs to take seriously.

My biggest gripe (after the undertray) appears to have been fixed with the new R33 software update, so things are getting better.
 
Scrolling through on the list of topics, I think I'm far from alone, and yes I have contacted with my dealer on the "official way" now, waiting for their response. It doesn't change the fact, the software part of the car feels "unfinished", and I hope from my heart, the part of the software what we, users can't see, works better than the surface shows.
 
You are most certainly not alone, but I think you are in a minority as regards the heating and the AEB.

You're dead right about the software I think. However this is the first car I have had that has had software anything like this sophisticated, so I don't have much of a benchmark for knowing how it's supposed to behave. I hear of a lot of other makes attracting similar complaints. One of our most vociferous complainers is apparently now complaining about his new car on its forum!

Most of my complaints are secondary issues - the USB player, the auto-locking not being able to be cancelled, the radio not staying off, and the stupid things like the temperatures on the HVAC screen being 5 degrees out and the colour of the SoC indicators not changing as it should. And the Sport/Snow thing. None of those affect the way the car drives.

It's also an absolute nonsense that they're still supplying cars with warped undertrays, and although some people claim to have a fix for the problem of the car not pre-heating if it's plugged in and not charging, nobody quite knows what that is.

But these things are common across all cars. The AEB and the unreliable heating aren't.
