Sounds like your dealer is trying to help out. I've had Chevy's for a number of years (now own a Chevy Camaro and Olds Silo). Electrical problems do not seem to be extraordinarily high for GM vehicles. To check for past recalls and Technical Service Bulletins for your Venture, go to http://www.nhtsa.dot.gov. On the left hand side there is a menu with "RECALL" listed as an option. From there you can search various bulletins and such based on MY, Make and Model of vehicle.
