Cruise fault since a software upgrade

[Alex1985]

The cruise control seems to have developed a mind of it's own since I had a software upgrade last week.

I only used it once last week following some traffic in a 40mph limit and the steering wheel became very difficult to turn a bit like fighting the LKA but in both directions I switched it of and have not used it since.
Before I contact the dealer has anybody noticed a change after the upgrade?

In MG pilot has the mode assist been changed from ACC to TJA?

As Ian says, it looks like the setting has been changed from ACC (Adaptive Cruise Control) to TJA (Traffic Jam Assist). With TJA as well as matching the speed of the car in front it also steers the car to follow it.

I've tried it once or maybe twice, but I blinked first and applied the brake because I had no where near enough confidence that it would behave itself.
