The alternator may fail causing the charge light to illuminate. Driving with this condition will eventually cause the engine to stall due to low system voltage.

The vehicle ran into problems at first when placing it into reverse and did not have enough power to reverse. It instead continued to roll down the hill I happened to be on. Later the same night of August 31, 2011, I had started up fine and when I went to make a U-Turn, the transmission kicked when in reverse and the lights dimmed to almost nothing. Less than 200 feet later, the vehicle stalled and would not start. The alternator was replaced a few weeks prior to this event. The battery is also 2 weeks old.
