its completely out of nowhere. your driving along fine, im usually cruising, doing about 60ish in 5th gear on a carriage way, no chugging, warning lights or anything; then the engine just shuts down instantly, every light on the dash comes on and you have no power at all. it'll run fine for days, except for the low power at a certain temp range which i can deal with, its a headache but not really a serious problem if thats all it is. then it'll just suddenly shut down when it hits full running temp.
there was a problem about 6 months ago with the eml light coming on but that was sorted as it was cam shaft sensors.
im pretty sure ive got the n42 (i think) 2l engine which ive found out has alot of issues.
