2007 Chevrolet Uplander LS 4dr Ext Minivan (3.9L 6cyl 4A)
Out of 1 year I have owned vehicle, it has been in the service shop 6 times because of passenger sliding door problems. It's either the door gets stuck in fully opened position (2x), 'pops' back open after closing, closes partially then stops. Door has been out of alignment 4 times, and the the front passenger door was out of alignment once. Other consumers have reported door opened while car was in motion. Chevy has been unable to fix and seems to be stymied.
Roominess, gas mileage.
Second row seats need improvement, like standard captain's chairs or at least wider seats. These are uncomfortable for passengers.
