3 Electrical System problem

Failure Date: 01/05/2016

While my 17 year old daughter was driving with the cruise control on in a 30 -40 mph zone, several lights came on, the power steering went out, and the vehicle stalled. She was on a small 2 lane road, and there were no warnings prior to the occurrence. She was very scared, she turned on the hazard lights and called me immediately. The vehicle then restarted and she drove home. Today (Jan. 5, 2016) the problem occurred again, fortunately in a slow speed zone again. She was able to restart the vehicle and continue driving. This problem is potentially very dangerous and needs to be addressed by the manufacturer, or they need to offer a buy back at full value for placing people at risk.

5 Electrical System problem

Failure Date: 11/29/2010

Just purchased a 2004 Mercury Mountaineer today. Driving home, using cruise/speed control at around 30mph and driving on a slight decline, the vehicle shut down. All indicator lights went on, and I had to coast to the side of the road. I put vehicle in park and restarted it without problem. There were no indicator lights (check-engine, etc. ) lit up. Immediately went to local Ford dealership and they had no clue, especially since the computer did not have any codes indicating a problem. . I'm canceling the check and returning the vehicle tomorrow.
