Engine Clicking And Tapping Noises problems of the 2010 Honda Odyssey

Van will start periodically. But the next day the battery will be dead & has been jumped off with jump box & other vehicles assist. But battery is new, terminals cleaned. Van will not even make a clicking sound. I feel that there is evidence of faulty ignition switch, starter relay or parked/neutral safety switch & maybe more depending on chassis electrical. The vehicle is also stationary until the next morning. This happens to be my wife's vehicle. . . Need this fixed ASAP. .

2 wks ago 1/7/18 we noticed a ticking noise that my husband said sounded like it was coming from the engine sitting at idle or moving. . He checked the oil and there was none there. . It was not time for a routine oil change and we get them done reg. At a nissian dealership. . He put 2 qts of oil and lucas additive to see if the noise would quite down. . However it did not and has started to get louder. . He then went to a mechanic friend who used a stethoscope and said that it was coming from the engine for sure. . We called the dealership who we got the van from and they said to bring it in because they didn't understand why there wasn't any oil in it. . They said that they did some research and show that Honda settled a lawsuit about fast oil comsuption and engine failure. . My local Honda dealership said that there is nothing they can do because the extended warranty went out 9/17 and it would need to have a cel. . I asked them if they would be able to start a complaint with american Honda but they said that since I'm not a customer of their dealership that it would be out of their control. . It sounds terrible at idle and when you are going through 1st and 2nd gear. . I'm afraid that it's not safe to drive with my kids in the car and will stall out anywhere. . I don't know what to do because a new engine will cost thousands of dollars and I'm afraid that the van is only worth like $6-7000 but we owe like $12900 still.
