Thank you for that interesting feedback. I am finding that MG Motors Ltd and their dealers have developed a conspiracy of silence on this matter. I have contacted MG Customer Services and my local MG Dealer several times about the dysfunctional software on this car but I am just stonewalled. What is astonishing is the MG Dealer's declaration that the car's software is not covered by the 7 year warranty and any investigation of software malfunctions will cost an initial payment of £144 plus charges for any parts or further work to correct the problem. This is simply disgraceful
 
The software IS covered by warranty and will be upgraded/patched if you have a genuine issue. Take your car to another dealer. Plenty have had software upgrades free of charge when they have reported an outstanding issue.
 
We have now owned our 2022 MG4 Trophy LR for three months and we can honestly say that it is far and away the most dangerous vehicle we have had the misfortune to drive. The journey home from the dealer in Oldham where we purchased the car was bad enough as we did not know how to disable the wretched lane-assist software which repeatedly tried to steer my wife into the nearside kerb or ditch. The software (and the connected cameras) are an absolute crock of excrement, clearly designed by some clueless geeks who are simply incompetent. The driver has little control over the behaviour of the car which is what makes the car so dangerous on the road. The so-called ‘safety features’ which the dysfunctional software controls have supposedly been incorporated in order to achieve an NCAP 5-star safety rating but as they don’t work properly, they have the opposite effect on the driver’s ability to control the car safely. We cannot believe that cars like this are allowed to be sold in the UK

This evening, the car has given us the fright of our lives. We were driving home at around 9.30pm along a clear, straight, tarmac, suburban road with a 30mph speed limit, a white line down the middle and kerbs on either side. I was maintaining 30mph up a slight incline with another car behind us. There were no parked cars on either side of the road and no oncoming vehicles. All of a sudden, the car slammed its brakes full on and brought the car to an abrupt halt for no reason at all that either of us could see. How the car behind us avoided running into the back of us, I don’t know but he must have thought we were drunk or stupid (we were neither). The ELK was disabled but some of the other ‘safety’ functions were enabled by default. We have regularly had the car brake suddenly for no reason, especially when travelling through contraflow road works with oncoming vehicles waiting at the lights on the opposite side of the road. The stupid software thinks that the car is heading for a head-on collision so brakes hard before the driver has a chance to steer the car through the chicane. This is not a safe feature, it is bonkers and effectively removes any control the driver has over what is a simple manoeuvre. As a 73 year old IAM Advanced Driver and a former saloon car racing driver, I wonder whatever happened to driver skill and responsibility. What if the car behind us crashes into us when the car slams its brakes on? Who is responsible then?

I don’t suppose the car’s software is clever enough to ‘remember’ or record the reason it had for slamming the brakes on tonight with no visible hazard. I recall seeing some message in RED that flashed up on the driver’s screen as the brakes were slammed on and I think the touchscreen briefly showed a picture of the road in front of us but both of these disappeared within seconds of the car being brought to a stop. We probably both sustained chest bruising from the seat belts in addition to the trauma of having the car decide to stop suddenly for no reason. We have now lost all confidence in the car so it will have to be replaced with something that allows the driver to have full control. We also own two classic cars, a 1949 Alvis TA14 and a 1999 Jaguar XKR. The Alvis has no seat belts, airbags or power-steering but it is a lot safer to drive than the MG4

I will be taking the car to my local MG Dealer but as the software is not covered by the manufacturer’s warranty, they will likely charge us £144 to poke around in the car’s computer brain and more than likely tell us that there is nothing wrong with the car. Looking at the various threads on this forum, it is clear that MG have known about this software malfunction for years
 
Try telling that to MG Motors Ltd Customer Services or their Local MG Dealer (as I have done). These dangerous cars should be taken off the road until the manufacturer can fix the software to return the car's controls to the driver. Trying to make a car safer to be driven by blind and incompetent drivers is a pointless and dangerous exercise. Whatever happened to driver skill and responsibility? Who is to blame when your car decides to slam the brakes on for no reason and the car behind crashes into you? Chasing NCAP 5-star safety ratings has led to bonkers software controls that are unsafe
 
Sorry to hear about your MG4. 🙁 Some folk to seem to drop on a bad un.
I'm presuming you did not have a good test drive in the car, prior to purchase. As this would have shown up the faults, and then not purchased. Hopefully some updates will, make it a lot better. 🙂👍
 
Thanks Salty. We used to call these rogue cars 'Friday Afternoon Specials' when they were hand-built in proper car factories in the UK. MG cars were special but not all of them were good cars. Skill levels in UK car plants were extremely variable which led to notorious reliability issues for many marques.
Now that new MG cars are built by robots in sterile sheds in China, there are surely fewer excuses for producing 'rogue' cars. I suspect that, in common with our old UK car workers, Chinese workers are poorly paid and are less reliant on their personal skill levels and totally reliant on the quality of the components they are given. The electronic components should have been designed and tested by skilled technicians so that they work properly in every car. This is clearly not the case

We bought the car from a Peugeot dealer so were not offered a test drive because the salesman did not know how to drive the car, let alone explain the controls. The drive home was a nightmare battling with the lane-assist software. This has been upgraded but it is still dangerous
 
I've turned all the panic settings to minimum in the car, it remembers those settings. Every time I get in to drive it, I turn the annoying LKA and totally worthless speed limit recognition systems off. That makes it quite a nice car to drive. I do see the occasional warning flash up on the screen - no idea what it is, it vanishes too quickly to read. I haven't had any phantom braking in the MG though, unlike the Tesla.
 
Earlier cars (2022) should defintely have had some software updates, some of which I think are mandatory for MG to offer for free (the 'locking you inside the car' one and the 'Lane Assist' one ?). Maybe worth checking with your local MG dealer.

In the meantime and as suggested above I'd turn off the "safety" features at the start of each trip if you don't like them and at least try and restore some faith in the car. It has become a habit for me every trip👍 . I've found there is a pretty good drivers car behind all the software !!
 
Sparky 2 , Enable "Towing mode " its at the bottom of the driving mode screen , you will need to scroll up to see it, I think you will appreciate its function. It will permanently turn off , emergency braking , lane departure etc . But you lose some other functions , ( rear parking sensors ) it basically turns the car into a early 2000s automatic Astra/ Golf .
On start up you might get a reminder , press cancel and away you go , enjoy !!!
Others with the Trophy model will give you a better understanding of its quirks and let us know which software , r number , version you are currently on, its on the systems page.
 
The "lock you in" issue was a full recall, which means people were contacted to bring their car in.
The "lane assist" fix is a less urgent "service campaign", which is the manufacturer telling dealerships "do this when you next have the car"
 
When I bought my Trophy in 2023 I had a couple of emergency stops whilst turning right. I set the sensitivity to medium and had no problems from then on. But since the SC077 update for LKA I've left the sensitivity at high because I found the car would no longer alert on medium where it used to do (chicane parked cars).
 
You need a software update. Lane Keep Assist is now fully solved. I did have sudden brakes but I have had none in the last year-ish. So I would suggest that the software update solves that too.

Electric cars are computers on wheels so it is thinking all the time and you need to show it you are aware. I use to creep slowly to the car in front in traffic jams without using the brake. That is when i got the sudden brakes sometimes. If you lightly press the brake pedal you are letting the car know that you know. So, what I am saying is use your indicators etc not only to let other cars know but to let your car know also what you are doing.


Most important though is get the latest software update.

That's atrocious.

I'd expect a test drive, even from a dealer not selling that brand. If the dealer wasn't prepared to offer test drives, why put the vehicle on the forecourt?
 
Since I had a bunch of software updates last year, I haven't had a single AEB false positive. It seems to be fixed now.

I do still keep the rear traffic alert stuff off because it kept flashing the hazards fast and confusing other drivers.
 
That's atrocious.

Totally agree. But I presume they didn't put his arm up his back and make him buy it. 🤔
 
As with a lot of issues it is more about how a dealer/manufacturer responds to their customers rather than the issue itself. AEB systems have been mandatory on all UK cars since 2022 and phantom braking scenarios are not unique to MG. However, when they happen they can be scary and the fact they are random can in some circumstances make them dangerous.

This is ADAS and EuroNCAP explaining the systems and why installing them was made mandatory:


There are lots of examples on the internet of law firms taking manufacturers to court over the implementation of the AEB system:


The use of the systems and their efficacy is also the matter for much discussion:
