I never knew the speed limit recognition was so bad

[SKORPION]

My MG4 TROPHY LONG RANGE of which I have had 3 weeks seems set at 20mph speed sign reading. If I go past a sign it either works 100% accurate or does not work at all. I took it to the MG dealership today and they did a diagnostic and said they could not find an issue. The diagnostic must have reset my date and time which I had to reset correctly. I then tested it and it was working. I drove home and later used the car and it no longer works again! Has anyone else experienced this issue or have any idea how to permanently correct it?

The Speed Sign recognition capability is not reliable. There is no "fix" for this.
It is an aid and no more. You cannot rely on it.

This I believe is a problem with new software. I have a 2025 SE SR and it does this. SOMETIMES it never reads the road speed and the next time it is working absolutely perfectly. The dealership will always say it is working correctly because they don't use it all the time to see the time it doesn't work.

I will look for a thread that started this.

Sep 3, 2024

Hello,

my first post there, not native english speaker, so I hope to get all right.

I'm from a month a proud owner of a Luxury64 MY24, and wile the car is truly awsome on any regard, is plagued by a quite annoying bug: when you start it for the first time speed signals recognition just lock on 50km/h.
I couldn't replicate this glitch on any other situation and the only workaround (over turning ISA off) is to lock the car, waith 30ish seconds and restart it.

Now, on MY24 the intelligent speed assistant is active by default at the start, and being a mandatory safety feature by the new...
