As of August 2015, information about Dodge Grand Caravan maintenance costs is online at U.S. News & World Report and Edmunds.com. Both offer information for several model years.
On the Dodge Grand Caravan Repairs page, U.S. News lets a site user input a specific vehicle year and local ZIP code. On the next page, the user selects a scheduled maintenance service period, such as 16,000 or 88,000 miles. This links to a listing of typical service procedures, required parts and price range for that maintenance appointment.
Edmund's True to Own section allows users to input makes, models, years and styles, such as the 2015 Dodge Grand Caravan SE Plus. The following page provides estimated costs, including maintenance fees, for five years.
