We have a 2006 Toyota Highlander Hybrid. There are a number of minor but annoying problems: 1) battery dead in morning 4 or 5 times for no apparent reason. 2) after turning off engine and opening door, buzzer occasionally goes off for no apparent reason. 3) some radio stations pick up a lot of static when brake pedal is pushed. 4) dvd carousel player picks up errors when attempting to play disks four or five. Wrote a letter to Toyota in 2007 regarding some of these issues but got no response. These problems could be related to the electronic issues we have recently been hearing about.
