Hazards flashing when braking?

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:

Thread 'Indicators flashing when stopping in traffic'

May 29, 2025

Hi all,

I’ve had my new HS Trophy PHEV for about 4 weeks now but only noticed something strange today. When braking a little more firmly to stop in traffic, I noticed in the reflection on the car in front that my front indicators were flashing and went off when I was stationary. The rears may have been flashing too, but I couldn’t tell because there was nothing visual or audible in the car say that the indicators were flashing.

I wasn’t braking hard at all so I don’t think it was anything to do with emergency braking and the forward collision warning didn’t come on. Has anyone come...

I have noticed the same reflection in the car infront, but i drive an MG4 Trophy.

It also happens if i am already stationary at traffic lights and someone passes by me in the same direction as me, but they have a green light. Say i am stopped and someone flies by with 54kmh. If they are too close to me that my rear parking sensors / blind spot monitoring maybe thinks they will crash into me so the car tries to make it self visible?

It is almost funny when a bicycle passes by me too close at 25kmh though.

Must be a shared logic of a shared system between these cars?

Can confirm this happens on S5 also. I am stopped in traffic w/auto hold, and the hazards would flash sometimes. Not sure about the logic, I was pretty close to the car in front of me, so I could see the front reflection. It could be rear cross traffic alert via the rear radar. I do live in a country where there are many lane-splitting motorbikes, maybe that's it...
