It happened to me once at a night time. I just pulled over, stopped the engine and started again after several minutes and everything was OK.
Edit: After reading other's comments, I realized that mine also related to coolant system. Some time after this incident I replaced radiator because of a coolant leak. May be this warning is related to that.
Pros: Everything was OK
Cons: coolant leak
2004 E46 320i manual with 116k miles. Bought it just over a year ago for \u00a32000 probably spent around \u00a31000 on it (radiator, air con, rocker cover gasket, oil sensor, boot switch, coil pack), not too bad for a 20 year old car I don\u2019t think. Only thing that doesn\u2019t work on it is the cruise control, it used to but recently stopped.
Pros: not too bad
Cons: cruise control stopped
Vehicle:
BMW
Mileage: 116000 km

The stock piece lasts well over a decade in my experience. That's more than enough for me for a part that fits and functions perfectly.
Pros: lasts over decade, perfect fit, functions perfectly

bmw makes a sad excuse of a cooling system with brittle plastic, sad plastic joins and a pathetic plastic and metal radiator, like that's gonna last
Cons: brittle plastic, sad joins, pathetic radiator
During Covid a lot of brand new genuine BMW parts had some issues so I had to change my radiator twice, was covered by BMW dealer after loads of back and forth. (There’s two part numbers for B48 engine main radiators and the dealer said the part number used was not meant for the car but the other radiator clearly wouldn’t fit)
Cons: parts had issues, changed twice
