Hi group went away on thursday with my "trailer" journey of approx 60 miles in daylight so would have thought battery would have been fully charged. Didn't use car till Tuesday morning only to find battery flat ( dashboard lights came on, only a click when pressing start button) jumped started vehicle and all was fine. Is it even worth phoning dealer or wait n see if it happens again? Vehicle is 09 GS.
Advice please.

for trailer please read Ca..v.n  Al C

See my new thread headed persistent flat battery problem. You are lucky it has done it only once! Can't offer any clues but it has certainly happened to me as well in similar circumstances.

If it were me I would get it checked out things like that only tend to let you down again at the worst possible moment. p****d off with a Digital Keyboard Warrior
