Just joined. I was googling "how to manually put a Cmax in neutral when it's dead" when I found this forum and thread. The wife's Cmax has been in to the dealer 5 times also. They've 1) replaced the battery once or twice, 2) did the software upgrade, 3) and said . . . . .huh. It's still under warranty so we call them every time it happens. I don't attempt to jump it, because some bean counter will probably tell me I voided the warranty, so I don't. (And yes, things like this have happened.) Anyway...... What is the wire chaffing deal? Where exactly in the rear hatch area is it located? If I can help the mechanic figure out what to look for, all the better. Bigger battery? How much bigger? Pretty close to turning this thing in for Lemon law. Car was the wife's choice, and I think she may have learned her lesson, since the Focus it replaced has 230K on it and still runs like a top. To save myself time and grief, if this Cmax can be made reliable, then all is good. Also, if anyone knows how to put it in neutral when it dies, it'll save the chance of the tow truck driver tearing the car up because it has to be dragged on to the truck. So far, so good, but at 5 times, pretty sure I'm pushing my luck.
