I have had a flat battery 4 times (April 10, May 21, June 10, June 22) on my Journey R/T 2011 - electrical system always checks out O.K After the third time, the dealer contacted Chrysler engineering and they suggested the steering switches (ones on back of steering wheel that control radio etc.) should be replaced. That work was done on June 15, 2011 and the battery was again flat on June 22, 2011. The service advisors report that they have had 4 others with similar complaints. I called Chrysler customer service and was given a file number. The service advisor at the dealership wants me to have the vehicle towed in to the dealer the next time it happens and they will contact Chrysler engineering again. The customer service rep. said to call them the next time it happens for followup.
