I have a 2006 Odyssey that sometimes will not start. I will admit a few times an interior light was on, but many times there was nothing left on. It is really strange because it will happen three or four times and then will be fine for months. I have taken it to the dealer and they say the battery and ignition are fine. The warranty is going to be up rather soon so I don't know what to do. Is there anyone who has any idea of what this could be. I have thought maybe electrical or something. When I turn the key, it just ticks, the engine doesn't even turn over. I greatly appreciate any help anyone can give. I have an instant jump box that will start the car, but talk about inconvenient.
