On three occasions on one day I experienced sudden loss of power. There was a slight bang from the radio as it happened but no light indications on dashboard. Lost steering, engine & electrics. Re-starts straight away. The previous day it had made the same sound but I only lost the radio and sat nav and they re-set within minutes so I thought no more of it. It was towed to Honda garage and has been there a week. Download from the computer confirms loss but no fault codes are bought up. They have checked "all the normal things" but no faults have been found. They have driven it for about 100 miles at various speeds etc but can not get the fault to replicate. They have now said to take it away and if the fault re-occurs to note all driving conditions ie temp, speed, gear etc However I am very nervous of it as I do a lot of motorway driving where suddenly stopping in the fast lane might not be a good idea! Does anyone have any experience of exactly the same problem and what was the cure? Thanks for any help forthcoming.
