If you check the internet, you will find a lot of gripes about this van and I experienced them all. electrical include brake lights shorting out, turn signals failing, power sliding door going out,and radio lights burning out. Mechanical include brakes constantly need serviced and the head gasket goes out at around 120,000 miles on almost ALL 3.4 motors. My buddy is a mechanic, he says he works on the head gaskets a lot, can do it in his sleep now. Cost $700 to replace head gasket as they have to plain down the aluminum heads to fit properly. Then you may as well replace timing belt and oil pump since you are that far into the motor, talking around $1100 now.
