We bought this van with low miles and the dealership was willing to do anything to get us into this van. We had zero problems except for the seat trim falling off, headlights full of water, and a loose windshield seal, until about 70K miles. Then the wheel bearings went, the transmission started shifting erratically, and the headlights were completely opaque. Sometimes the radio won't shut off, and the electric door is wonky. Windshield washer tank leaks. Have replaced 12 bulbs in 4 months and the light sockets were melted! Brake lights come and go. Acceleration is measured with a calendar.
Really, there are many. I guess the best is the message center just above the windshield, I also like the dual air conditioners; wife likes to bake and I like to freeze, and we both can be happy.
GM should have done a little more research in the refinement area. This This vehicle is boring, but has been solidly reliable. Others have not been so blessed, but we plan to drive the wheels off this thing because resale is poor.
