There has been ungoing electrical issues since buying this vehicle new. The headlights have stopped working and there is an intermittent problem with the lights and the internal chime. Sometimes the lights don't come on or the chimes can not be heard and then it is working properly again. The engine in the vehicle ihad to be orepalced just before it went to 60000 miles so, it has an 2005 engine. This engine has a hard revv when shifting gears. There are gas fumes coming into the cabin.
