Battery Dead problems of the 2010 Toyota Highlander Hybrid

Multiple battery failures requiring jump starts: seven (7) times since I bought this SUV in Feb 2011. Three times there was a possible known cause for the battery drain: the passenger vanity mirror light was left on for 15 minutes, 2 hours, and an unknown length of time. None of these three episodes was significant enough to cause a completely dead battery in one that has been evaluated as in excellent condition. I drive in the mountains all winter. Getting stranded in an isolated place can be deadly due too exposure, risk of collision on single lane snow-occluded roads with 2-way traffic and fast snow plows. Other Toyota Highlander Hybrid owners have had the same problem. Twice now the dealer has said there is "no problem" with the battery.
