Are you sure that was when it ran the hours up? They are notorious for continuing to run when the key is almost, but not quite off. My wife and I were told by our dealer to remove the key and toss it in a cup holder every time we stop. Right now I am on my third hour meter but need to remember to subtract 83 hours from the true reading as I let a neighbor use it and he left the key on just a little bit. Can't remember how I came up with 83 hours being added on while it was stopped but I felt confident of the number. I first ran into the problem at the dealership. My wife and I test drove it, liked it, signed the papers but wanted a roof and glass windshield installed. It had 2 hours on the meter. One week later I was at the dealership and saw it now had 99 hours. I commented on it and it had its first new meter when it was delivered.
