Lane Keep Assist feature

[Pianoman]

You should have no issues with that level of LKA.

You’d be surprised!

You’d be surprised!

I had a Scalextric set which was once my Grandfather’s and it was amazing how they could come flying off the track. Who knew that one day I’d be driving a real electric car!

Hope your drivings improved over the intervening years

Had car for one week and been for a few drives on B class roads. I'm struggling to relax at the wheel. In my previous car I would cruise resting arm on door with fingers lightly controlling steering. Not any more. Two hands on wheel at all times ready to fight sudden unexpected tugs on wheel. Despite keeping in middle of lane I am finding the LKA sensor goes crazy on rough road surfaces (most roads in Scotland), is severely effected when damp road surfaces are drying out as well as repaired road surfaces that are different shade from rest of road. Downright dangerous if you ask me. Its only a matter of time before a MG4 wipes out a cyclist due to this feature.

Absolutely agree - I've only had my MG4 Trophy for a week now and the LKA is an absolute nightmare - its far more aggressive than on my previous car a Hyundai I30N - lets have a permanent disable option or sort it out MG!

There won't be a "permanent disable" option. It has to reset every time the car is switched on to receive a 5-star rating from EuroNCAP.

Said this before, but here goes again.

The manual for the car states clearly that the LKA may function incorrectly on a road with poor lane markings, or with no markings at all, where it may latch on to a rut or something like that and steer the car in an unwanted direction. That's fair warning! It then goes on to say that in that situation it should be turned off IMMEDIATELY. Bold type and italics and so on. Again, fair warning.

The problem is that it's impossible to do this. Tap on the car icon. Tap on MG Pilot. Tap on the actual deactivate button. Then tap on "yes of course I'm sure you bloody moron!" All with your left hand stretched away from the steering wheel, and having to look carefully at the infotainment screen to make sure you tap the right bit. Which can be kind of hard in a moving car. In a moving car which is actively trying to steer you into the ditch it's downright suicidal.

In order to avoid encountering this scenario, the only recourse is to turn the damn LKA off when you start the car. Routinely. Thus absolutely negating any safety advantage it might offer on better roads.

The answer is to provide a physical one-button off/on switch for the LKA that can be accessed quickly and easily if the thing is playing up. The two volume switches on the centre console are a waste of space because everybody controls the stereo volume from the right joystick. Programme one to switch the LKA off, and the other to switch the fog lights on (the other situation where you have to stab at a touchscreen in a very awkward position to do something you have to do while driving), and we'd be sorted.

 

[Les burrows]

Rolfe you’re right again it would be sorted, and give control back to the driver where it should be, but because of NCAP rules it is never going to happen.
Now my wife’s 4 had an update for the door locking issue a couple of months ago and I asked the dealer to disable LKA altogether but they told me they are not allowed to because of NCAPs safety suite, so i said to my wife just turn the toggle to off before you set off and she now always gets in the car goes to driving and selects Eco mode and then goes in to MG Pilot and checks that LKA is off and she has told me before that it is off on most occasions so no need to.
I have wrote before on here they can keep NCAP and we will decide how to drive the car would probably reduce the price as well.

[Rolfe]

I don't see why a physical button to turn LKA off would be against NCAP rules at all. We're allowed to turn it off. We're instructed to turn it off while we're driving if it starts to function erratically. It's just that it's impossible to do that without parking up. So people turn it off before they start, pre-emptively.

If there was a single button to press to turn it off, I might even leave it on when I set off. Not as it is now though.

That's fair warning! It then goes on to say that in that situation it should be turned off IMMEDIATELY. Bold type and italics and so on. Again, fair wawarning.So basically

So, basically, as per my experience, this is almost every road in Scotland and be prepared to be killed by the car on such roads. Especially when damp.
Last week I wrote to MG UK about this and got standard fob off, however it is now going back to dealers in 4 weeks as they told me there may be a recent software update to make it less severe. I don't want it at all !!

 

[Rolfe]

Totally agree. I had it on when I took the car on a joyride down the A701 the day after I collected it. I parked up in Moffat and read the handbook to find out how to get rid of it and it has not been on since. (Nor has that barefaced liar called the speed limit recognition system.)

I don't want it at all either, but given the NCAP situation the sane and sensible thing is to map one of the useless volume buttons to give the driver an immediate one-press "off" option. We also need a physical button to turn the fog lamps on and off, so that's both volume buttons nicely re-purposed.

I wish.

the only problem with that part of the plan is someone had the somewhat odd idea to make the volume shortcut on the steering wheel change the volume of the Sat Nav for example when using maps on CarPlay, so there would be no way to adjust the volume of the music if those physical buttons weren’t there.

I really can’t get my head around why this was done, especially given that there is a pull down menu to adjust those volumes, just doesn’t make sense to me.

That said, there is no reason at all why the favourite buttons on the steering wheel can’t be programmable to allow changes such as regen or lka etc…those buttons already control different functions in the SE and Trophy, so clearly they can be programmed as shortcuts.

A physical button is not against ncap rules I have one on my car,on the right side of steering wheel on the dash

Robert Llewellyn, of the Fully Charged Show, is currently driving an MG4, He drove it to and from the Harrogate Live show and commented about the agressive LKA in one of the talks. I drive an MG ZS EV Trophy Connect and its LKA has been very good while driving over the last 3 months. However, today for some reason it yanked the steering for no apparent reason. It happened only once but I was in the middle of a lane anyway so something spooked the sensors. I hope that doesn't happen again.

 

[Les burrows]

The time will come when this type of car will be used a lot more in the hire car business, maybe a few years away as yet but they will replace the Corsa and fiesta in the airports etc here and abroad, and the idea behind eurocap is safety that is obtained by have as many as possible of these features to default to the on setting so that when someone strange to the car starts to drive it all these features are there to improve their safety joke in my book, simple cruise control is all I want nothing more. And I will do the driving not the vehicles software.

Hmmm. But yes, one of the programmable buttons would do it too.

I still want some way to turn the fog lights on without touching the infotainment screen. I think where they have that "button" is downright dangerous. And right now I couldn't reach it anyway, because I've wrenched my left shoulder.

 

[Annaka]

I'v just taken delivery of the MG4 Trophy and am very happy besides the LKA. After turning it off I would drive around and find now and then the LKA would turn itself back on ! I've just worked out why it does this and doesn't stay off. If you have your headlights on Auto when you go under a tree ie a big shadow over the car sensor the lights turn on and so does the LKA, so set the lights to anything but Auto and the LKA will stay in the state that you ask it too. Simple fix but took a bit of head scratching to sort it out.

 

[Rolfe]

Look up the thread on how to stop the lights doing that. It works.

Funny thing is, I've read other people say the LKA will do this in synchronization with the lights, but when I had the problem with the lights, before I got the sensor cover off, mine didn't do this. I wonder if it's really related to the infotainment screen changing from light to dark mode? I have mine set to stay on light at the moment.

 

[Annaka]

hey good point might be the infotainment screen ...I'll try that out today by setting it to either light or dark, and report back

 

[Vingnut]

The left star button can controll regen, I set mine up that way because that stupid acc does not have it's own regen setting but uses the one we set in the main display. So I mostly like to drive in regen 3 mode but the acc is very harsh in that mode, so I switch to adaptive when using acc.

 

[NewMG4me]

First drive to work after car delivered yesterday- a mix of country roads and dual carriageway. LKA did kick in once but was very gentle so I’m going to try to live with it for now.
Speed sign recognition can get in the bin though
