We have had our Edge for app. six months. During that time, it has failed to start several times. We can boost the battery and it will start (so far). We thought it was just the battery, but when we took it to the dealership, they said everything checked out, and there was no problem they could find. It is getting very frustrating to carry a battery booster for a new vehicle. It may run fine for a month, and I may drive it several miles, do my shopping or whatever, and then it refuses to start. We have had it to the dealership for the third time (it is there now). Can anyone HELP?
