I have a 2012 Honda Odyssey EX RES with just over 94,000 miles on it. Beginning on March 27, my wife, who is the main driver of the car, went to start the car and nothing came on the dashboard. It then started after about 5 minutes of waiting.

Between this date and April 2, the car would start up and run fine, including the morning of April 2. In the early afternoon of April 2, I went to start the car. As I turned the key past I and II, dashboard lights came on and then went I went to 0, the lights went off and it would not start. The interior lights of the car also went off. After about 3 minutes, the lights came on in the interior, car started.

On April 9, turned the key, lights on the dash came on and then off before I even turned to fully start. Wait about 3 minutes, interior lights come on, start car.

I have many different examples from the first time above through now including:

• Sometimes the whole dashboard is dark or 3 or 4 dashboard lights will be dimly lit
• When this happens, no power works-headlights, interior lights, locking the car, etc.
• When it is not working ling enough, I have to enter the security code for the radio for it to operate
• When I try to start and the it wont turn on, I have opened the door and shut it to find that the dashboard illuminates. Sometimes I then am able to start the car right away and sometimes wait a few minutes

We just got back from a week long vacation where the car was not turned on for a good 6 days. Today, April 29, was the worst examples so far. It happened multiple times today and with a longer wait for it to actually start. 5, 10, maybe even 15 minutes. Sometimes when I would open the door, interior and dash lights would come on. Sometimes they wouldn't. Just around 730 PM EST, the car had been off for a good 30-45 minutes. Opened the door, nterior lights come on. Turn the key, lights on dash are on, then they go off. Walked the dog for 10-15 minutes. Came back, open the door, no interior or dash illumination. Then the interior did come on. Put key in, turn to 1 and then 2. Dashboard lights are lit. Turn to ignition, lights go off. Open and shut door. Dash illuminated, interior lights on Put key in, turn to 1, lights go off.

This was taken to a dealer the week of April 2. They had it for 2 days and it started up each time of course! I spoke directly with the technician wh said they could rule out the battery, starter, and alternator. They spoke with Honda directly too because they were very stuck on what the issue was. They think it might be the immobilizer or under dash fuse box but don't know for sure. Given today's events, I of course want to bring it back but weary of them having it because of Murphy's Law and it always starting as well as renting a car.

Coming here for some insight and guidance! Not very knowledgeable about car maintenance and what each part does.
