Limp mode/stop start fault

[Keefums]

Hi all
Yesterday on the motorway my car (2019) went into limp mode, like it was misfiring and start/stops failure displayed on screen and engine management light was on

Garage where we bought the car came and picked it up ( only had it 31days)

Garage called to say they connect to diagnostic machine ..hasn't recorded fault and no historic faults, engine management light is now off.
They have tested the battery and have told us they cannot fi d any fault

Anyone have similar issues or have an idea what's wrong ?

I have a 2019 too and had this happen just once. Got it home then put it on a battery recharge and recondition and it hasn't happened since.
