2025 MG S5 EV DRL PROBLEM (daytime running lights)

[Armani]

Hi guys! I am new to this forum and this is my first post here. I hope i am at the right place.
I bought brand new MG S5 Trophy two months ago. Lovely car, i am almost happy with it.
I noticed one strange thing today whilst driving. I was behind a lorry and was coming to a stop at traffic lights. When the car nearly stopped, i noticed at the reflection of the lorry that my Daytime Running Lights started flashing yellow!!! After full stop, they changed back to white colour. I will include a link to a short YouTube video from my Dashcam to show you what i mean, as it seems i cannot upload videos here.

Does anybody know what was that??? Some weird safety feature?? Or electrical glitch?
It was not emergency braking and i didn't touch anything accidentally in a car. And i think it was only DRL that were flashing yellow, not my mirrors' indicators and hopefully not rear indicators.
I don't know has the car been doing this before or not but today was the first time I noticed that and to be honest it doesn't look right to me.

Hello @Armani, welcome to MGEVs, is it the same as this?

I just went to write a post and noticed this has already been discussed regarding the HS PHEV (see link), but thought I’d post this anyway in case any MGS5 drivers notice the same/have any information on it:

Hello Clive, thank you fo your reply. Yes i think it might be the same. Can this feature be turned off? Flashing lights might be misleading for other drivers.

You probably can't turn it off, you'll have to press the little car button at the bottom of the screen and look through the various settings.

It can be turned off in the MG Pilot screen. You need to turn off Rear Driver Assist and unless you save the setting in custom settings it will switch back on when you restart the car.

I suggest you tap the information icon (i) because it also turns off several other features.

I've seen this a few times, and I just reckon that the "boys in the back room" have their reasons for thinking that this improves safety

I'd assume it thinks you are stopping too close the vehicle in front
I've not seen this happen on my car.

It could be that the vehicle behind you came in too fast towards you. Its called Rear Collision Warning and states "Alarm Mode . When there is a risk of collision, the hazard warning lamps on your vehicle flash to warn the vehicles behind".

Or possibly that it detects cars coming from behind in the other lane, and fails to understand that they are in fact, in the other lane?

I havent noticed this happening on my car, but if it doesnt give a chime then i wouldnt notice it,,

You only notice it when the vehicle in front is reflective.
