My C3 randomly cuts out while I'm driving. No pattern and it can go for weeks without it happening Sometimes it may happen while idling at traffic lights sometimes while actually driving or turning corners. It has been into the garage - one I use regularly and trust - but they couldn't find anything wrong and it didn't cut out while it was with them overnight. The car is serviced regularly and I have had a new battery fitted since the problem started and this can happen on a short or long journey. It has been happening for months now and can be a little unnerving to say the least. Has this happened to anyone on here or any suggestions as to what the cause might be?
