Sudden automatic braking issue (merged, MG4)

[Bricktop X PWR]

The radar sensor is behind the coloured panel below the number plate and between the vent grilles.

Not it isn't.

It is behind the front bumper.
You cannot see it from outside the car.

It's just to the right of the front camera.

Good to know, I thought it was the bit in the middle of the splitter

So did I, till I got told off some months ago!

We all thought the same , even though the user manual tells you to keep the area clear of dirt/snow etc , it does not tell you where it is? So , what's under the falsie?

I'm surprised it's not lower since it can see the car beyond the car in front.

It just guesstimates that, it often enough “sees” a second car that’s not there, or ghostly motorcyclists.

No it's not guessing, it never suggests there is one there when there isn't one present, but does (most of the time) when there is.

Yes you did!!!!!

You naughty cheeky boy...

But I'm afraid at some point you are correct.

Ha, you can lend mine and enjoy the fantom cars ahead of you. It also spots motorcycles when there is none.

Last week it smashed the brakes when it thought there was a lorry in front of me (clean screen, no dirt on radar). It kicked back from 100 to 65 before I got it accelerating again. On the motorway....

I will be connecting my camera again in case it becomes a standard.

That’s a strong, factual sounding, statement coming from someone who’s never driven my car

My MG4 sees vehicles that aren’t there all the time. Even when sitting at a public charger the other day, it identified a building’s pillars as motorcycles all around the front of the car. So yes, it’s just guess work.

It also doesn’t detect car sized trailers, which strikes me as odd seeing as it detects buildings as motorcycles.

In my four months of ownership I've not had an AEB incident, but I always set the sensitivity to low level when getting into the car. I cleaned the small squarish area below the bumper for the first time this week. I'd rather keep the AEB enabled but I can fully understand decision to turn it off should a incident of unwarranted braking occur.

It sounds like yours may need re-calibrating, last week mine correctly identified a rabbit running across the road.

The car is barely four months old so I doubt it needs recalibrating, especially taking into account other drivers reporting guessing by the car. What is the symbol for a rabbit on the screen? Could it be a motorcycle?

Definitely not a motorcycle, they definitely look like motorcycles. Never seen a rabbit. Could it be a hare .

If it shows up as a pedestrian on the screen it could’ve been the Easter Bunny

I have the same model, 17 months old & 22,000km. I I haven't had any issues like you have described. I used to turn LKA off but leave it on all the time now. It just made me drive more accurately.

Automatic braking has worked when the car detected a pedestrian emerging from between 2 cars. The car decided they were walking in to my path but they were just going to the drivers door to get in. The car reacted before I would have but software doesn't have human intuition.

Oh I leave everything on as default, I have near zero issues with LKA and the likes, I just don’t believe the car really knows what’s in front of it. It sees obstacles and guesses what they might be in my experience.

I'm another "no pre-flight procedure" driver. I think that the software and firmware set that comes with Australian 2024 MG4s is pretty safe and usable. It's a great shame that the set delivered in many other regions is so poor and apparently dangerous.

I believe the software and firmware is likely the same, but the issue is that the climate, sunlight and roads are very different and the system has essentially been built for an environment where roads are wide, without narrow bends, and don't have dappled shadows from trees or frequent patches of drizzle, mist and fog.

What makes you think we have none of those things?
