Today I was toggling between the various driving modes, in the mean time on screen checking which wheels were powered. I ended in Sport mode again. When I had to slow down for the next crossing the car was regenerative braking, but not enough to halt in time. It also felt like the regenerative braking suddenly stopped. When I pushed the brake pedal with normal force nothing much happened and I had to apply a lot more pressure to get the car to stop. Five minutes later it happened again, just before I was back home. It felt like the snow mode kicked in or similar.
Anyway, back home, I checked the braking fluid, just to be sure. I also had new tyres fitted yesterday. Nothing reported by the car.
Could this be some kind of software glitch ?

It's not a glitch, that's how sport mode is programmed in MG4.
If you need full regen potential you need to keep it in normal or eco.
 
I've only used Sport mode once by accident/ignorance, didn't know how to turn it off or how I got there. The acceleration and steering were more than I'd expected as far as response goes, but the battery % dropped like I'd put a hole in the tank, it used 20% from full in the stretch I did with 7% yesterday ...... great for impressing new folk to a poverty pack model EV, but not for use far from home where I can plug it back in to recharge :ROFLMAO:

When you toggle through driving modes SNOW mode will set the regen to 1, it may be that this did not change back to 3 when you then moved through the other modes to get back to SPORT. Just something to check.
