Hi all, thanks for the responses, much appreciated. Really welcome the experience.
@NowforThe5th, thanks for the input. Fully appreciate the details provided and correction on terminology, thank you (apologies for spelling, I'm a bit on the dyslexic side of life when typing!).
Whilst I agree with the comments as below, the result is more severe and much earlier than I would anticipate, and I just cannot believe this is normal behaviour from a car. I am not some noob winging for the sake of it, this is a genuine issue. If this is the manufacturer's intended performance, I would not recommend anyone buying the car (although i love it otherwise, this is a show stopper for me). Far from this ute being slow to react, it is reacting much earlier than a normal car.

The above makes sense conceptually, but not how early it engages or how aggressively given the conditions (e.g. driving on dry sealed smooth roads).
I'm no sponsored F1 driver, but I have a hell of a lot of experience in motor vehicles, particularly on-road and race tracks and having vehicles on their limits or close too. One of my gigs is a superbike coach, lucky enough to buzz around on ~200bhp bikes with all sorts of wizardry and control systems these days. I also get to drive a load of cars, from competitor branded dual-cabs through to performance Euro-trash, both track and road. In all of these never have I ever had a vehicle engage like this. My other half as a passenger has been shocked by it, as have other people driving my car, so I know it is a legitimate issue for most people.
The vehicle is not having any issues with acceleration etc (i can moderate the throttle fine and avoid this even unloaded), and if it breaks traction here, no issues, this is normal. I ave the GLS, so can use super select when needed, but this is not a solution to the issue at hand as traction is not being lost, it is very far from this point.
It is under normal driving conditions- normally off the throttle or on a steady throttle that it occurs, always in corners (so yes Yaw related makes sense). It is not just cutting the throttle, but actively engaging the braking system (you can hear and feel this). It is not trying to retard or reduce rear wheel spin/traction loss, but rather it appears to be trying to correct what it perceives as an out of control vehicle or situation and it feels like brakes applied to front wheels (e.g. the fishtailing noted above, even though it is not). Like when you try and throw a modern car into a handbrake turn and it begins applying breaks to front wheels to try and avoid the vehicle crossing up.
Nothing to do with tyres etc as it is actually not breaking traction at all, it is a very long way from this point, and it was the same with the factory spec tyres as it is with my Toyo AT's. I even had it happen in a 50 zone going around a normal suburban corner off throttle the other day.
My suspicion was a faulty wheel speed sensor or Yaw sensor or similar, I have asked my dealer this question But my dealer won't touch anything without a fault code. They replaced one faulty wheel speed sensor, but the problem persists, and when this went it was completely different activating a fault light and keeping it illuminated.
Called Mitsubishi Australia who told me I need to go via my dealer. My dealer says they cannot do anything so talk to Mitsubishi Australia... quite circular and I am left frustrated by an otherwise great car.
