I know that I am suppose to enter multiple problems separately. This same problem has occurred 33 times in 31 months of ownership. There is an electrical problem that drains my battery. The battery has been tested many times and checks out OK. The problem is when I turn a key on to run anything electrical for a short time the battery goes dead. *Turn key to accessory and listen to radio 15 - 20 minutes, dead battery. *Leave rear gate open 20 minutes, dead battery. *Leave flashers on in an emergency for 15 minutes, dead battery. (key not on) *Make 2 blue tooth cell phone calls total time 12 minutes (I checked the call timer on cell phone), dead battery. *Open & close sliding door 3 times key not on - dead battery. *Ran an electric tire pump that plugs into the vans electrical port and added air to 4 tires - dead battery.

I can keep going on - on... you get the picture. My Toyota dealer service tells me this is normal when I turn the key on six computers are activated and drains the battery. I have never had a dead battery on other vehicles that I owned doing thee same operation. My son owns a 2011 Dodge Caravan and battery has never gone dead
