On 5/29/2004 I purchased my Toyota Sienna. I started having "mysterious" lights coming on at all different times. On 7/15/2004, I went out to my car and it wouldn't start. This was the beginning of a nightmare. Since then my car has been in the shop at least 6 times for this problem. I have not had my car start at least once a month since I purchased it. I would usually just jump the battery but they could never tell me the reason why it kept on happening. There were times that I couldn't even leave my doors open for 5 minutes without it wearing the battery down. When the battery is checked it is always fine. When the battery is fully charged I have the interior lights turn on for no reason. They have put in a new battery and replaced the jbl audio switch because that had been shown to turn on intermittently and drain the battery/engine. Neither of these solutions have worked. They finally told me that my car had too many "bells and whistles" (which all are factory installed) and that I need to connect to a car charger when I come home or to go on long drives at least once a week.
