My husband and I bought a brand new 2007 Dodge on December 31, 2006. We had to take it back to be worked on this weekend because the vehicle dies when you back up. We left the dealership and the transmission was changing gears really hard, but after 10 miles or so it seemed to go away. About an hour later my husband backed out of a parking place and the vehicle died. I called the dealer and they want us to leave it over night so they can drive it. I don't think they will be able to fix it, especially because it doesn't do it everytime you back up. I'm worried about pulling into traffic with my children and the vehicle stalling. Is their anything I can do if they can't fix the problem?
