Defective Battery and Charging System
 In December, 2009, I entered the vehicle one morning and it would not start, the  battery was dead.  I called Auto Club, and they jump started the vehicle.  4 months later, the same thing happened, and I attempted to jump start it myself, having purchased a set of cables in the interim.  I was unsuccessful, and called for a tow.  The vehicle could not be jump started, and was towed to a Toyota dealer.  I had purchased an extended warranty, and asked that any repairs be covered under it.  I was told that I had damaged a special fuse, and my actions had rendered the warranty invalid. The battery system is defective.  Several other reviews describe the same problem.
