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. I am pursuing correction through the local Toyota customer relations manager and will follow through with Toyota's customer experience center and the California dispute settlement center if a prompt local solution is not achieved. answers.edmunds.com/question-we-have-A-2010-Toyota-highlander-hybrid-the-battery-is-constantly-dying-on-it-example-leave-door-open-10-minutes-and-it-S-dead-144840.aspx

Hybird system overrides all wheel drive system when tires slip disabling the system, in effect rendering it nonfunctional, so that the generator is not damaged. Combustion engine will not turn on and when you hit gas nothing happens. I had to be towed out. Service quoted after examining "did experience concern trac/vcs cuts power to wheel when slippage occurs. Unfortunatly, there is no way to disable this. Everything works as designed." My 2006 Highlander hybrid had similar incident almost causing me to be run over as power cut off on highway and I was told the computer needed to be reset and it was fine. A car equipped with all wheel drive should function as a all wheel drive not be designed to be non functional when it is needed. The first time a barely survived getting to the side of the highway. This time I had to be towed on top of a mountain two hours from anywhere in snowshoe West Virginia. Service anticipates no way to correct.
