I drove mini cooper R56 for a very short distance for about 4 minutes, the whole car died completely. The battery was working fine, everything else seemed fine but the car died altogether with no symptoms.
The car however came back after 3 hours automatically. It appears like maybe this was something to do with theft prevention because its very strange that the key getting stuck (not getting released if you push it again) and car completely dead and then coming back to life after 3 hours. What could have triggered it?
Update: Found someone else also experiencing exactly similar issue in Mini Forum, but unfortunately no valid solution so far.
