I have had my Honda Odyssey for three weeks, and have had it to the dealer three times now for a "check fuel cap" warning coming on. I make sure I tighten it. When we drove it home the first time (with only 12 miles on it) the warning came on. Anyone have the same issue? The dealer "fixed" it twice, now they are keeping it for a few days to thoroughly check it out. I am very frustrated! Also, the passenger sliding door (not power) is extremely hard to open sometimes, especially when it is cold.
