Bought van new and it performed well until it reached 60,000 miles. Then the electric door locks began to fail. The power window motor failed on drivers side. Water pump and and thermostat @ 80,000. 100,000 differential bearings went bad. 119,000 cooling leak around intake manifold gasket. Always maintained van and never abused.
At this point none!
Don't buy G.M. products. They are not designed to last but engineered to fall apart so you will buy another one.
