MG4 Main Screen Stopped Working

[loydex]

On top of everything else the main screen stays off. Unless I have switched it off somehow? Just stopped working since this morning when I sat in the car. Locking and unlocking didn't help. Whats next???

Try rebooting. Press and hold the home button under the screen for at least 10 seconds

I have a reboot problem with touch screen,
Just switch off the on, while radio on or sat nav.
Done a reboot still the problem happens every time I drive.
Only had it 2 years on a 3 year old car. 7 year warranty lost it because they said I didn’t service the car. It was too much to do on universal credit. Now the MG Dealer wants 130.00 just to look at it.

Not sure you are on the right forum. This is the MG4 forum and its only been out for about two months

Same MGs touch screen problems

How do you know that? Does the MG ZS EV forum tell you that the MG4 has the same system? Look at that forum and it will tell it possibly needs a software update as of 2021

Bit confused really: have you been servicing the car or not? You will need to for the warranty to be valid, but independent garage servicing can qualify if they used MG parts.

You have an EV and you are on Univeral Credit? I presume your circumstances changed and am sorry to hear that.

As others have said, if we knew what model of car you had, would be easier to help you.

His profile states MG ZS EV?

No, when I got the used car, they didn’t tell me about the warranty. Don’t really know what that was after being on motability for 30 years, until they changed the disability rules.
Tried several garages who didn’t want to touch it and said go to the dealer. Even one garage said that to change the touch screen could cost up to £1,000 quid with the labour and parts as well. So that put me off as well. They also said just replace the touch screen and hard drive is another option.
Overall a 2019 year car, had it since 2020 and already playing up, just imagine another 6 years down the line.
I have contact MG Headquarters for answers.

I think the bus is calling and ditching the car altogether.

It’s a MG ZS Exclusive car.
2019 year car,
Serviced in 2020.

Difficult situation. It really needs proper diagnostics at MG but if you can't afford it then ?‍

It may well be software or hardware, one cheap one expensive but at least you would know for certain. I think this is beyond a forum answer to be honest and you need a dealership that may be a little understanding of your situation and try and meet your financial restrictions somewhere where both parties are happy.

The sad part is having the car 'serviced' would have had no effect on the part in question.
They're basically saying, 'you didn't scratch our back so we won't return the favour'
I wonder if anyone has ever got satisfaction from the 7 year warranty to date ?

Right Alan, if I have this in the wrong place please feel free to move it thanks.
So yesterday I took my wife’s MG4 SeSr to the bodyshop to get the damage to the door repaired at an authorised MG bodyshop, so I parked the car went into the office there to hand in the Keys and the guy said it was the first MG4 they had had in the bodyshop, so I said we’ll do you know how to start the car he said it’s just like others isn’t it with a stop/ start button no I said it’s not so I took him out side to the car to show him, I had park the car 10 minutes previously so I open the car got in screen in front of the steering wheel came to life but the other did not, now I had had this 1/2 times on my MG5 mk1 so I knew about pressing and holding the home button, I also had read about it many times on here in these forums but this was the first time on the MG4 for me, anyhow finger on home button for 1/2 minutes nothing is happening small screen is still ok and saying ready but with foot on brake I’m unable to select any drive mode.

So got out the car locked it with the button on the handle reopened it again via the handle got in nothing has change on the home button again still nothing got back out of the car again this time I locked the car with the key fob waited a couple of minutes and reopened it with the key fob open the door and got back in and again the small screen came on but not the other so finger back on the home button for around 30 seconds and it came alive and I could select a drive mode and all was well again, I try it again a couple of times no problems just decide to post this in case anyone else might experience a similar issue I know there are several post that manage to get the system to work but this was a little bit different.

Les, with this cars software there could be multiple "burps" that need different ways of getting "it"...whatever that maybe...working again, so one fix doesn't cover all applies. Thanks for sharing your method. The more complex car software becomes the more room there is for glitches irrespective of manufacturer, however the MG4 in particular appears to need a larger iron than normal to press out the problems at the moment. Given time all will no doubt be resolved. I just wish that they had taken advantage of a new platform and new model to up testing and quality control etc. ahead of launch instead of perhaps rushing to the marketplace imo.

The weirdest thing happened to my infortainment main screen over the weekend. I plugged in a new USB C that contained some of my music. First, the USB drive was not recognised and there was a brief message to that effect, followed by another "Can not find activity" whenever I pressed the settings icon. No other icon responded and Android Auto did not work . The AC works with the hard button. My left favorite key stopped working. Followed by the screen restarting in a loop every few seconds. Speed limit detection failure was also displayed. There was no history of the error on my extensive search in both English and Chinese forums.

I took a gamble and went ahead to disconnect all USB connections then removed the battery negative terminal for about 15mins. Problem persisted.

Then I reconnected to my phone for Android Auto. This time it connected and worked. I checked other functions and it mostly returned to normal. All buttons worked fine again, my left favorite key also started working. Speed limit icon was still missing from driver's screen, but that got restored after exiting the car, lock, unlock and sitting in the driver seat again. As did access to the MG Pilot, which until this point did not work.

Earlier that day, I had update MG Android iSmart to v2.0 8. I will not think that had anything to do with this.

Hi gravity not sure if you might have done this but this does normally recovers the infotainment screen and functions so sit in the car to power it up foot on the brake to enter ready mode then press and keep pressed the whole time the home screen button the one below the screen next to the volume button’s not the one in the top right of the screen ignore that one, keep the button pressed for a short while could be a minute or 2 the screen will close down and then start to reboot keep it pressed until you see the MG logo then let the button go but not before you see the MG logo this enables a hard reset hope it might help.

Thank Les. I did try that bit no luck. I found the fault/cure. I downgraded iSmartApp to v2.06. Deleted all bluetooth connections to the car on my phone. Started over with Android Auto. After that the screen functioned normally and the speed limit error went away too.

It definitely had something to do with my phone (Android 12), Android Auto, and iSmart upgrade to v2.08.
